| 摘 要： | 研究了三维高层钢结构交错桁架的动力内力反应,在计算水平地震作用下交错桁架的动力反应时考虑土-结构共同作用。在进行内力计算与分析时,同时研究交错桁架结构底柱固定与考虑共同作用两种情况,对水平地震作用下的最大动力反应进行了研究。计算结果表明:考虑土-结构共同作用时,水平地震作用下交错桁架柱子的最大内力将减少,并且其内力变化也更加缓和。

| Abstract: | The dynamic internal forces of the three dimensions high-rise steel staggered truss were studied,and the influence of soil-structure interaction(SSI) were considered when the responses of this system under horizontal seismic was calculated.The internal forces of staggered truss system with column foot fixed and with pile group's foundation considering SSI were calculated and investigated.The maximum dynamic response of that under horizontal seismic was also investigated.The result shows that the maximum res... |
