带连体的高层综合办公楼的连体结构设计

结合河南省洛阳市洛龙区行政中心综合办公楼的设计,探讨了连体结构选型、结构计算及经济分析等问题。研究表明,连体结构的地震扭转效应特别明显,连接体桁架的布置方式及楼板刚度对整体结构的计算结果十分敏感,设计时应用多种软件计算并比较分析,选择合适的连体结构形式。另外本文还重点论证了连接体钢结构方案的优越性。

Conjoined Structure Design of a Office Building

Tall building with conjoined structure is a kind of typical high-rise building.Because its power transmission way and earthquake resistance performance are quite complex,its mechanical analysis,structural design and construction are relatively difficult.In this paper,combined with the design of Luo-long district office building,the conjoined structure type,structural computation and economical analysis are discussed.The study indicates that earthquake torsion effect of conjoined structure is distinct and the lay out of conjoined truss and stiffness of floor are very sensitive to computation results of the whole structure.The designed structure should be computed with some different computation software and these results should be compared and analysed in order to choose suitable conjoined structure type.Moreover,superiority of conjoined steel truss is demonstrated in this paper.
