I'm a sophomore now, and that's all the professional courses I've taken. Mathematics is the basis of specialized courses, so I counted him in. There is also a mess to learn.
There is a kind of component in high-rise buildings called energy-consuming component, which is usually located in an unimportant position and silently bears its own responsibilities. When the earthquake disaster comes, these components will be assigned an extremely important task: sacrifice themselves (crushed) to consume most of the earthquake energy to ensure the safety of other components. Like a civilized dog.
At that time, I studied this course from the foundation, the main body to the capping construction technology and matters needing attention, without elaborating. I didn't know much about this book because I didn't participate in the site too much during my school days. I didn't further understand the meaning of this book until I participated in the site construction.
