Personally, I think these directions are easier to write about steel structures, because there are still many immature places in steel structures that can be studied in the past two years, which have great research value and prospects ~ ~ ~ ~
It is as big as studying the overall design of prestressed long-span steel structures, as small as studying the connection and anchorage between components, and also studying the steel structure engineering market from a social perspective, and so on ~ ~ ~ ~ ~
You can check the relevant information in this field (go to the library, surf the Internet and ask the tutor) and you will find that there are so many things to learn ~ ~ ~ ~
Don't worry, relax!
