simple t-stub steel connection

The following contents are studied this paper:(1) 3D models of simple T-stub steel connection and endplate connection are developed, implementing geometric non-linearity, material non-linearity in both room temperature and high temperature as well as contact non-linearity in fire.
主要研究工作包括以下内容:(1)考虑几何非线性、常温及高温下的材料非线性和接触非线性因素,建立短T型钢连接和梁柱端板连接的三维有限元模型。
