摘要:

针对施工方便、造价低廉的交错桁架结构体系的设计方法、构造细节及防震减灾问题,对影响交错桁架结构体系的整体延性性能的若干结构因素,如桁架不落地、桁架构件、柱的连接形式及建筑高宽比等进行了研究。研究结果表明:在交错桁架设计中,应采用抗弯矩连接,避免采用底层桁架不落地的交错桁架结构形式。该研究结果及建议对交错桁架结构体系在中国的推广和应用有积极的意义。

Abstract:

Improved fabricated efficiencies and low mill prices make staggered-truss structure system winning choice for multistorey residential construction. To generalize the use of the system, more works need to be done on design methodology, details of seismic design and seismic design methodology. Authors investigated influence of some factors on global ductility of staggered-truss framing system. Those factors included non-truss on the firstfloor, the model of connection of elements and ratio of building height andbuilding width. Some suggestions about seismic design of the staggered-truss framing system were offered. It is good to the application and popularization of the staggered-truss framing system in China.
