摘要(Abstract):

通过对有上柱的空腹式格构钢柱以及完全空腹式格构钢柱在低周反复荷载作用下的构件试验,研究了空腹式格构钢柱的滞回性能及抗震性能。结果表明,对于有上柱的空腹式格构钢柱,上柱底端部位属于薄弱部位,最早发生破坏;对于完全空腹式格构钢柱,中间的受力小梁最早发生破坏,构件具有良好的延性性能,耗能性能明显;另外,为研究空腹式格构钢柱在地震作用下的动力反应及破坏机理提供了两种恢复力模型,为进一步对其进行弹塑性地震反应分析提供了条件。
The seismic behavior and the hysteretic behavior of open spandrel latticed steel columns was studied through the test of open spandrel latticed steel columns with the upper prop and the test of the complete open spandrel latticed steel columns.The results show that the end lap of the upper prop is the weak part of the open spandrel latticed steel columns with the upper prop,destroyed earliest.In addition,intermediate force received beams are destroyed earliest,it has good ductility performance,and its energy dissipation ability is very obvious.Furthermore,two restoring force models for the study on the dynamic response and the failure mechanism of open spandrel latticed steel columns are supplied,provides the conditions for further elastoplastic seismic response analysis.
