The increasingly serious tinnitus, as well as the frequent red-green color blindness, made He Ying uneasy at the moment. In the speakers around him, Liang Sige introduced the deep voice of the ancient tower damaged in the earthquake:

"The masonry tower was seriously damaged in this earthquake."

"In the area of seismic intensity VI and above, a total of 61 ancient towers were damaged, of which 16 were partially collapsed or completely collapsed."

Every word that drilled into his ears was like a loud sound of masonry collapsing, shaking He Ying's eardrums.

But she still silently held the empty cardboard box, and sat calmly and seriously in the chair like hundreds of teachers and students in the school, regarding Liang Sige's sharing as a rare experience. It's just that she can't control it, and the dampness in her palm will always slowly seep into the light brown texture of the carton with every force she exerts on her fingertips.

There was a question she had asked countless times about all the nerves, the bloodlines, and every cell in her body.

That is, eleven years have passed since that incident, and she has received enough comfort and care. But why, every time I hear those two words, I still have such a strong stress reaction?

With her weakness back then, she couldn't prevent that kind of disaster from harming people. So for her grandfather's death, she didn't need to blame herself at all.

So, why?

Is it because he pestered his grandfather to talk about this and that, delaying his repair progress, and regretting it?

Or did you regret it because you told your grandfather that you wanted to stay there for a few more days, so you encountered such a tragedy?

No, it's neither.

Grandpa has always been excellent in every restoration job.

He said that every ancient building, every statue, and every painting is a testament to the civilization left by our predecessors. This verification is not that we have seen them and repaired them, but that we have let them know and let the younger generations know that we have been here. In this way, the Chinese civilization can be passed on forever.

Therefore, grandpa will not change his working hours because of himself, will not blame himself for saving people and sacrificed, and does not want to see himself now.

In that case, what can't she let go?

From the perspective of structural type, the slenderness ratio is greater than 3.0 and the damage degree of the pavilion tower is the most serious, because the wall of the pavilion tower is relatively thin and the spatial rigidity is relatively small; The degree of collapse of the tower body increases with the increase of seismic intensity, and the height of the mountain has an obvious amplification effect on the seismic action, so the ancient tower built on the top of the mountain will be more likely to collapse; The quality of the tower's construction is also closely related to its ability to resist collapse. ”

Liang Sige's voice was low and powerful, but in He Ying's ears, it was intermittent.

The structure type of the ancient tower has a great correlation with the degree of seismic damage, and for the pavilion-type ancient tower located in the intensity area of the seismic fortification intensity of 7 degrees or more, and the slenderness ratio is greater than 3.0, it is necessary to pay more attention to the seismic collapse identification of the structure, so that we can repair this kind of ancient tower for the purpose of earthquake resistance."

At this point in the speech, Liang Sige saw that several students in the audience raised their hands, so he temporarily stopped to communicate with everyone. After choosing for a long time, he casually pointed to a boy who looked elegant like himself, wearing glasses:

"That's it."

Lin Ru got up elegantly, took the microphone and asked:

"Hello Senior Liang, I am Lin Ru from Tianyang University, thank you for sharing. What I would like to ask is, based on what you have just said, can I understand that the ultimate purpose of your research on the seismic performance of ancient towers is only to better strengthen and protect them, but you cannot prevent them from being damaged by earthquakes, nor can you use their structural characteristics to design and build earthquake-resistant buildings? ”

Such questions are too sharp and even quite provocative. The school instantly fell silent, and the teachers and students in the audience raised their heads one after another, casting different emotions at Liang Sige.

Among these people, some are puzzled, some are probing, some are sweating for him, and of course some are gloating.

Liang Sige just pushed his glasses and glanced at Lin Ru deeply, before coldly spit out two words into the microphone:

"Yes."

"Huh?!" There was a roar in the hall.

"Is there any mistake, didn't Liang Sige study a lot of earthquake-resistant structures? Why do you say that? ”

"But what he said is right, he was originally a major in ancient architecture, and the purpose of studying these ancient towers is to protect ancient buildings, strictly speaking, architectural design is not his main business."

"Isn't it! I've always read his papers as if they were the Bible! Now that he has overturned his theory, what should I do? ”

"yes!"

Just when the students couldn't understand Liang Sige's speech, they heard the familiar voice in the speaker and rang again.

"The reason I say this is because, in my personal opinion, no matter how we study earthquake-resistant structures, we need to have a sense of reverence for nature."

The hall was quiet again.

His voice became clearer and clearer in He Ying's ears, who had been closing his eyes:

"Human beings are very small in front of nature. In the face of extremely destructive natural disasters, no matter how perfect the building structure is, there is no 100% guarantee that it will not be damaged, which is why I have repeatedly emphasized the correlation between the site where the ancient pagoda was built and the degree of earthquake damage. As for the study of the seismic performance of the ancient tower, my original intention was indeed to repair and strengthen the ancient tower, but at the same time, in the process of research, there was a kind of thinking, that is, what kind of ancient building structure should we use as a reference for architectural design, so as to better cope with the earthquake that is not so destructive? So, an all-timber tower in SZ City, Shanxi Province, built in 1056, came into my field of vision."

In the following content, Liang Sige gave a brief introduction to the research direction of the corresponding county wooden tower, and the teachers and students of the entire school, including Lou Xinyue and Tang Guoguo, also listened to the lecture meticulously.

But when He Ying heard Liang Sige's words, "Human beings are very small in front of nature", his heart tightened, and he completely blocked other contents from his eardrums.

Is that the case?

The reason why I have a stress reaction because of the memory of the earthquake is not because of the earthquake itself, nor because of the death of my grandfather. But because in her subconscious, she didn't believe that the structure of ancient Chinese buildings could resist natural disasters such as earthquakes?

That's impossible!

A student majoring in ancient architecture who loves ancient architecture and wants to fight for it all his life will lose confidence in his professional beliefs? This is ridiculous!

However, who stipulates that people who are engaged in the ancient construction industry must believe in the earthquake resistance of ancient buildings?

He Ying was entangled in his heart, but he still comforted himself: it was a natural disaster that was rare in a century, and there have never been several records in history, so such destructive power cannot be used as a measure of the seismic performance of mortise and tenon structures. Moreover, it is a well-established fact that ancient Chinese buildings have the strongest seismic performance.

What are you thinking?

Her color blindness was caused by eye lesions, and there could be no other cause.

Countless thoughts flashed through He Ying's mind and were overturned. repeated this several times, and was finally interrupted by the sweet voice of the host on stage:

"Thank you very much Liang Sige for your wonderful sharing, and at the same time, please pay attention to the registration time of the National University Earthquake Exchange Competition. Strive to be able to discuss the seismic views of ancient buildings with Liang Sige on the field. Next, we will invite Professor Liang Zhibo to come to the stage and talk about the idea of the research on the "Evaluation Standard for Seismic Resilience of Buildings". ”

In the warm applause of everyone, Liang Sige and Liang Zhibo completed the handover of the stage.

"In this case, let me first introduce the background of the development of the standard."

Although Professor Liang Zhibo is over half a hundred years old, he still speaks like a bell:

"The seismic resilience of a building refers to the ability of a building to maintain and restore its original building function after a set level of seismic action. In recent years, scholars mainly engaged in earthquake engineering and structural engineering research in the United States, RB and other countries have successively put forward the concept of seismic toughness and conducted in-depth research. The requirements for the comprehensive seismic performance of buildings, building complexes and cities have also been upgraded from "earthquake safety" to "earthquake resilience". At present, there are three international standards for the evaluation of seismic resilience of buildings, namely FEMA-P58, the REDi Rating System and the USRC Building Rating System."

Hearing Professor Liang start to talk about dry goods, He Ying wanted to take out her mobile phone and record a video to go back to study, but she found that she couldn't calm down no matter what, so she planned to go out to breathe, and by the way, take a look at Chu Mingchen's research model and how the research was going.

It's just that what she didn't expect was that.

As soon as she went out with her front foot, the boy sitting next to her pointed to the cardboard box on her seat and said to Liang Sige: "Third child, isn't this express box mine?" You said you were going to load things, why did you get here? ”

Liang Sige looked over, but he couldn't see clearly because of the distance.

The boy was afraid that he wouldn't believe it, so he took a picture of the courier on the carton and sent it to his WeChat, and said, "I didn't lie to you!" The recipient on it still has my name written on it! ”

Seeing this photo, Liang Sige's face was obviously displeased.

Drop a sentence, "I'll go out for a while, and you will come out when the time comes." And he got up and left.

He Ying went to the bathroom first, walked around but didn't find Chu Mingchen, and walked aimlessly to the door of the theater next door. There was no performance scheduled in the theater today, and He Ying was suddenly a little curious about what was inside, so he tried to pull the entrance door.

It's actually open?

So, she opened the crack in the door wider.

Turning sideways through the crack in the door, she turned around and just pulled the door shut, when she heard a series of familiar and strange voices coming from behind her:

"Dad, I promised you to come and speak, and I have already done it. I have something to go back to school in a while, and I won't attend the evening drinking party, and the next two days will be very busy, so don't call me. ”

"I'm really busy."

"You have to tell the truth, I delayed for two days, all to help you make a model."

"But I told you, don't give my model to a girl I don't know."

"At this point, I don't have much to say. But please tell her, don't add me on WeChat in the name of asking me to answer questions, and you can't make phone calls. And I really didn't go to the drinking party, so that's it, hung up. ”

Although He Ying couldn't see the boy's appearance, he could still hear from his indifferent voice that he was not a person to be messed with, and he must be very mindful of others eavesdropping on his phone calls.

However, I really didn't mean to, I think I should be fine if I apologize, right?

But just as she turned around, she heard the boy's self-talk that made her jaw drop.

"Ahhh What do these two couples want to do? Why would you give my model to a girl! Be! I'll admit that girl looks like my thing, but they don't have to be so deliberate to let her sit in my place, right? I can't listen to them next time, for such a boring occasion! It really is! Liang Sige, you should be angry, don't always be kidnapped by their morality! Ahh!!hhhhh ”

Then, Liang Sige rubbed his hair and turned around, looking at He Ying at the door.

Because of the suddenness of the incident, he even forgot to put away his face, and after being bullied by his parents, he had a helpless and aggrieved expression.

He Ying's head was instantly struck by lightning.

I can't believe that the boy in front of me with a chicken nest and messy hair will be the same person as the high-spirited god on stage just now!

From his words, no matter how shocked He Ying was, he could hear that Liang Sige had misunderstood him.

"Well, listen to me, actually." He Ying wanted to talk about the misunderstanding, at least to make it clear that it was an accident that he came.

But seeing that Liang Sige instantly changed to an indifferent expression, he asked himself:

"What the hell do you want to do? Want my WeChat? Impossible. ”

"What?" He Ying looked shocked, couldn't believe that this person was so narcissistic, laughed self-deprecatingly and turned away, and in order to express his anger, he also slammed the door shut!

As a result, I heard a scream from inside the door:

"Ah!! My nose! ”

No way?

He Ying hurriedly opened the door, wanting to see how he was injured, but as soon as he said "I'm sorry", he saw the pale Liang Sige looking at the nosebleed on his fingers, and said a word weakly:

"Blood~~~?"

Then, with a roll of his eyes, he fainted.
