摘要
从基本概念出发,阐述了次内力的概念,探讨了国内外对次内力问题的多种看法,以及求解次内力的多种方法,并结合工程实例进行了比较,以帮助人们正确计算次应力,从而正确进行结构设计。
It commences on basic concept,concept of the secondary internal force is described,several thoughts on the secondary internal force problem at home and abroad are discussed,as well as multiple methods of solving secondary internal force,and combining with project case gets comparison,so as to help people correctly calculate the secondary internal force,thus getting structure design correctly.
