摘要
通过分析预应力等效荷载的特点,对预应力等效荷载法在有限元分析中的具体实现展开讨论,提出将预应力筋与结构单元对应分段,利用有效预应力将预应力荷载统一转化为单元集中荷载的办法,简化了荷载类型,便于程序处理。
This paper discusses the application of prestress equivalent load to infinite element calculation,analyzes the performance of prestress equivalent load,points out that by taking the effective prestress,turning prestress equivalent load to element concentrated load can simplify the load types and conveniently deal by program.
