房屋抗震设计的竖向地震动反应谱研究

A study of response spectra of vertical ground motion for buildings antiseismic design

在建筑结构设计中,为了保证结构安全可靠,都要考虑地震荷载。破坏性地震之后,通常把造成建筑物损害的直接原因归因于竖向地震动。文中以国内外多次地震的竖向地震动加速度记录为数据基础,总结竖向加速度反应谱特征,通过对竖向反应谱特征的分析,给出竖向地震动反应谱,为工程结构的抗震设计提供理论依据。

In order to protect building from destroy, the earthquake force in designing structure needs to be considered. After earthquake, it is often concluded the destruction has resulted from the vertical ground motion. Based on data of vertical ground motion acceleration, from earthquake recoids at home and abroad, it analyzes the feature of response spectra of vertical ground motion, and works out vertical ground motion response spectra. This will provide theoretical basis for the related design.
