【摘要】 汶川地震中非结构构件有不同程度的破坏。总结非结构构件震害反应特征,将非结构构件分为加速度敏感型构件、位移敏感型构件和混合敏感型构件,对非结构构件提出加速度指标、位移角指标和混合指标;探讨各指标的分析方法,提出加速度放大系数谱和位移幅值谱的概念和生成方法,建议拟合楼层包络谱,指导非结构构件的计算和分析;在总结国内外对于非结构构件计算方法的基础上,提出基于性能的非结构构件分析方法;对非结构构件抗震性能试验方法进行探讨,为正确评价其抗震性能提供支持。更多还原

【Abstract】 The damage states of non-structural components were various during Wenchuan earthquake.The earthquake damage characteristics of the non-structural components are classified into three kinds of non-structural components, which are acceleration sensitivity components,displacement sensitivity components and hybrid sensitivity components with acceleration indicies,displacement indicies and hybrid indices.The acceleration amplification factor sprectrum and relative displacement sprectrum and the methods to produce them are put forward.The floor enveloped response specctrum is specially advised to direct the calculation and seismic analysis.Prime equations of China and abroad on calculation the equivalent sieismic force are discussed and further research is mentioned.Experimental seismic test approaches are discussed make it convinent to examine the seismic performance of them.更多还原
