| 摘 要： | 腹板柱复合空腹桁架转换结构(以下简称腹板柱转换结构)是一种新型的结构形式,通过在框架梁间的适当位置设置腹板柱,使梁上出现多个弯矩峰值点,同时弯矩峰值也大大降低,从而优化结构的内力分布。通过模型试验对腹板柱转换结构进行了抗震性能试验研究,分析了结构在水平往复荷载作用下的屈服机理、承载力、滞回特性、位移延性,得出该结构形式具有较好的抗震性能,并对该结构形式提出了设计建议。该结构已应用于建筑物外套框架增层工程中,取得了满意的效果。

| Abstract: | Composite truss transfer structure with web-type column(web-type column transfer structure) is a new kind of structure,where web-type columns are set up between beams.The function of web-type columns is to adjust the moment of the structures.It can realize reasonable distribution of moment in structures.It reduces the peak value of moment in the end of girders and makes the moment balance in the whole structures.It is presented the experimental study of seismic behavior on web-type column transfer structure.The failure mechanism,bearing capacity,hysteresis capacity and ductility of the structure are analyzed under lateral cyclic load.The structure has better aseismic resistance.The suggestions on design are given.This transfer structure is successfully applied to extension-story engineering of building. |
