Lud.Hangzhou Zhejiang 311209 China) Abstract:In recent years the emerging plex model structure system makes the connection model of members more and more plex.Joint design guarantees the structure safety and reliability security.But for such plex joints the codes have no explicit formulae.Test and research are limited by some conditions such as cost and construction period in practice engineering.So 3-D model and finite element analysis are effective to solve the problems.In this article the optimization design and finite element analysis for the cast steel joints are introduced based on Hangzhou Olympic Sports Center Stadium project.
