大跨度连续刚构抗震设计研究

The study on the earth resistance of the long span continuous rigid-frame

以一座四跨连续刚构为例,对大跨度连续刚构抗震设计进行了研究,计算分别采用了反应谱、线性时程和非线性时程分析的方法,考虑了结构关键部位在50年10%和50年3%两个超越概率水平下的地震响应。

Taking a long-span rigid frame with four continuous span as an example, the paper studies on the earth resistance of the long span continuous rigid-frame, uses the response spectra, the linear dynamic method and the nonlinear dynamic method to calculate, considers the earthquake response of the key parts of the structure in which the exceeding probabilities are ten percent and three percent in fifty years.
