| 摘 要： | L型框架码头平面布置不规则,质量、刚度不均匀、不对称,水平地震作用下应考虑扭转影响。采用SAP2000有限元分析软件,考虑沿建筑结构的两个主轴方向及与主轴斜交方向的水平地震作用,对内河某L型布置的框架码头进行扭转耦联的振型反应谱分析。通过数值计算求得L布置码头结构在地震作用下的内力反应和位移变形,对码头结构的动力承载性状做出了评价,找出结构薄弱位置,为该类工程的结构设计和方案优化提供参考依据。

| Abstract: | L-framed wharf is irregular in plan with uneven distributed mass and stiffness, and torsion effect shall be considered under the horizontal earthquake effects. Using the finite element analysis software SAP2000, and considering the horizontal earthquake induced response along two main axes direction and spindle oblique direction of the structure, this article analyzes the elastic response spectrum considering torsion-coupled effects of L-framed wharf in inland river. Based on the numerical calculation for the internal force response and displacement deformation of this arrangement wharf structure under seismic action, this paper makes the evaluation for the dynamic bearing behavior of the wharf structure, and finds out the structural weak position, serving as reference for the engineering structure design and optimization. |
