某综合服务办公楼结构设计

Structure design of a complex service building

结合某综合服务办公楼的结构设计,分析了中外联合设计时对建筑形体及构件布置规则性等抗震设计内容的不同要求。针对办公楼竖向构件不连续的特点,使用MIDAS软件对采用不同转换结构构件的整体模型进行分析,计算结果表明:斜腹杆桁架、空腹桁架、实腹钢梁均能满足结构受力要求,三种转换结构的跨中挠度及用钢量依次增加。着重介绍方钢管与圆钢管连接的节点设计方法。

Combined with the structural design of a complex service building,the difference in regularity of building configuration and structural assembly between China and foreign countries in seismic design was analyzed.The office building has an irregular arrangement in vertical,and diverse transfer structures were analyzed with MIDAS software.The results show that transfer truss,vierendeel truss and transfer beam are also adapted to the structure,and the deformation,steel consumption are increased in turn.The design problems about the joints of different steel tube were introduced.
