威海香水海项目钢异形柱支撑框架结构设计

Structure design of steel special-shaped column braced frame for Weihai Perfume Sea Project

通过对于小高层住宅钢异形柱支撑框架结构进行整体分析,确定异形柱及支撑的布置方案。对异形柱和钢梁的连接节点选用四种方案进行有限元分析,给出各种连接方式下的内力及位移的比较结果。分析结果表明:钢异形柱支撑框架结构满足受力及建筑使用功能要求;合理设计异形柱-梁连接节点,可以有效减小局部应力集中,降低施工难度。结构方案及节点连接方式具有较好的工程应用参考价值。

For the small high-rise residential steel special-shaped column braced frame structure for Weihai Perfume Sea Project, through the overall analysis, determine the special-shaped column and braces layout plan. Four schemes were selected to analyze the joint of special-shaped column and steel beam, and the results of internal force and displacement were given. The analysis results show that the steel special-shaped column braced frame structure meets the requirements of stress and building function;reasonable design of special-shaped column beam joint can effectively reduce the local stress concentration and reduce the construction difficulty. The structural scheme and joint connection mode have good reference value in engineering application.
