无侧移半刚性连接钢-混凝土组合框架的二阶内力分析

The Analysis of Second Order Internal Force in Non-sway Semi Rigid Connection Composite Frames

钢-混凝土组合框架结构在高层建筑中应用越来越广泛,但是目前的钢结构规范采用的仍然是纯钢框架的分析方法。本文章提出了组合框架的二阶分析方法,并给出适用的内力计算公式,该方法可以考虑楼盖的组合效应以及节点半刚性连接的影响,可为完善组合结构相关的规范规程提供理论依据。

The composite frames are widely used much in tall structures. But The design method of steel frame was adopted in design code for the steel structures. The second order Analysis method and calculation formula ofinteral force were established. The influence of composite action and semi rigid co rmection can be taken into account. This method can provide theoretical basis for the improvement of related codes o fcompo site structures.
