摘要

大跨度维修机库结构动力特性复杂,研究该类结构并进行多维地震响应具有重要的实用意义。本文在分析平板网架类大跨机库动力特性的基础上,对机库进行了单维以及多维地震作用下的时程分析,研究了机库屋盖杆件在不同方向地震波作用下的内力分布特点,进而给出了机库在各种工况下的杆件内力放大系数分布规律。结果表明,水平地震作用下机库下部支撑柱附近的杆件往往内力值与内力放大系数均较大,在设计中应给予足够重视。最后通过大量计算分析研究了地震动输入角度对结构主要响应指标的影响效果。
The dynamic characteristics of long-span hangar are very complex,and it has practical significance to study the seismic response of this structure under multi-dimensional earthquake.Based on the dynamic characteristic analysis of long-span hangar which structure type is plate space frame,time-history analysis of one hangar under single-dimension and three-dimension seismic wave is carried out.Distribution characteristics of internal force of member belong to the roof is studied,furthermore magnification factors of internal force are given out.Results show that the members near columns should be paid more attention during design.Finally the influence of seismic wave input angle to structural seismic response is studied through a great deal of calculation and analysis.
