H型钢梁与钢管混凝土束刚接节点的优化设计与分析

Optimal Design and Analysis of Rigid Connection of H-section Steel Beam to ConcreteFilled Steel Tubular Beam

钢管混凝土束剪力墙组合结构用于高层住宅楼具有绿色环保,自重轻,施工速度快,用工少,抗震性能好,布局灵活,无凸柱,梁截面小,增加使用面积的天然优势[1]。在住宅类建筑中具有相当广阔的应用前景,本文主要从可靠性及节约用钢量方便施工等方面对规范建议的节点做法做出优化建议,通过简化计算及SAP2000有限元分析两种途径进行可靠性计算。最终给出节点处常用端板的建议厚度以供相关工程人员参考。

CONCRETE-FILLED STEEL tubular shear wall composite structure for high-rise residential buildings has the advantages of green environmental protection,light weight,fast construction speed,less labor,good seismic performance,flexible layout,no convex columns,small beam cross-section,increasing the use of natural advantages 1.It has a wide application prospect in residential buildings.This paper mainly makes optimization suggestions on the recommended joint practices from the aspects of reliability and saving steel quantity for convenient construction,the reliability calculation is carried out through simplified calculation and SAP2000 finite element analysis.Finally,the recommended thickness of the common end plate at the joint is given for the reference of related engineers.
