【摘要】 结合交错桁架结构的特点,分别建立了混合式交错桁架、加十字支撑混合式交错桁架以及空腹式交错桁架有限元模型,并对其在多遇地震下进行时程分析,得到结构在地震时的动力响应,通过结果比较得出交错桁架的优点,并在一定程度上探讨了交错桁架结构的抗震性能。更多还原

【Abstract】 Combining with the characteristics of the staggered truss system,it establishes finite element of hybrid staggered truss system,hybrid staggered truss system with cross support and vierendeel type staggered truss system.And it has time history analysis to obtain the dynamic response of the structure,get the extent of the staggered truss system under comparison.To investigate the seismic performance of the staggered truss system.更多还原
