Analysis of the Response of Reinforced Concrete Buildings During the 1987 Whittier Earthquake

1987年加利福尼亚州惠蒂尔地震后，几个钢筋混凝土结构的强烈地震记录被恢复。这些记录中的大多数都显示了加速度随高度的显著放大。其中一些记录来自1971年圣费尔南多地震后重建或抗震加固的建筑物。这项研究将回顾钢筋混凝土建筑的现有数据，选择具有代表性的建筑，并使用现有的计算机程序对这些建筑进行钢筋混凝土结构的非线性分析。通过将计算机分析的结果与现有数据进行比较，将得出现有分析模型的适用性和有效性、地震动随建筑物类型和高度的放大程度以及抗震加固的有效性的结论。这项研究将为钢筋混凝土建筑的现有分析模型和抗震加固技术提供有价值的评价。

Strong motion records from several reinforced concrete structures were recovered after the 1987 Whittier, California earthquake. Most of these records showed significant amplification of the acceleration with height. Some of the records come from buildings that were either rebuilt or seismically strengthened following the 1971 San Fernando earthquake. This study will review the available data from reinforced concrete buildings, to select representative buildings, and to analyze these buildings using available computer codes for the nonlinear analysis of reinforced concrete structures. By comparing the results of the computer analysis to the available data, conclusions will be drawn regarding the applicability and validity of available analytical models, the amplification of earthquake motion as related to building type and height, and the effectiveness of seismic strengthening. This study would provide a valuable evaluation of current analytical models and seismic strengthening techniques for reinforced concrete buildings.
