按抗震要求设计高层建筑时,满足规定的侧移限值要求是结构设计人员最关心的问题。本文采用简化的连续-离散化力学模型,分析得到振型地震荷载及相应的楼层侧移反应,经组合以满足结构的侧移限值要求,不仅可以进行后继地震反应分析,而且也是初步设计阶段确定主体结构尺寸的直观依据。由于联络矩阵元素具有明显的分布规律,因此,用微机分析时可充分利用这一特点加快计算速度。
When designing high-rise buildings according to seismic requirements, meeting the requirements of the lateral shift limit is a major concern for structural designers. In this paper, a simplified continuous-discrete mechanical model is used to analyze and obtain the mode-induced seismic load and the corresponding floor-side lateral motion response. After combining to meet the lateral shift limit requirements of the structure, not only the subsequent seismic response analysis can be performed, but also the preliminary design stage. The intuitive basis for determining the size of the main structure. Because the elements of the liaison matrix have obvious distribution rules, when using computer analysis, this feature can be fully utilized to accelerate the calculation speed.
