【摘要】：对天津国家会展中心展览大厅凹形四弦桁架结构特点进行了详细分析介绍,对凹形四弦桁架结构进行了详细的静、动力特性及地震作用参与组合下的结构内力分析,得到了结构杆件的内力分布情况、凹形四弦桁架结构的刚度分布及人字柱柱脚支座受力特点.同时针对国家会展中心展览大厅进行了结构方案比选,在柱子形式及约束等一致的前提下,针对屋盖结构分别进行不同结构体系与凹形四弦桁架结构体系的对比分析,得出不同结构体系的受力特点及经济效益上的优缺点.对凹形四弦桁架柱的结构性能有了全面了解,为工程的实施提供了参考依据.
[Abstract]:The characteristics of concave four-chord truss structure in the exhibition hall of Tianjin National Convention and Exhibition Center are analyzed in detail. The static and dynamic characteristics of concave four-chord truss structure and the internal force of the concave four-chord truss structure are analyzed in detail.The distribution of internal force of structural members, the stiffness distribution of concave four-chord truss structure and the bearing characteristics of herringbone column foot are obtained.At the same time, according to the exhibition hall of the National Convention and Exhibition Center, the structure scheme is compared and selected. Under the premise of the same column form and constraint, the comparison and analysis of different structure system and concave four-chord truss structure system are carried out respectively for the roof structure.The mechanical characteristics of different structural systems and the advantages and disadvantages of economic benefits are obtained.The structural performance of concave four chord truss columns is fully understood, which provides a reference for the implementation of engineering.
