    • In order to determine the seismic vulnerability of a structure, a vibration sensor is placed on each of the top surface of a layer of the structure and the ground surface near the structure so as to record vibrations. A seismic vulnerability data processor assumes a transfer function of vibration of the top surface of the layer of the structure based on a spectral ratio between the vibration recorded on the top surface of the layer of the structure and the vibration recorded on the ground surface, thereby obtaining a predominant frequency and amplification factor of vibration of the top surface of the layer of the structure. A seismic vulnerability index of the layer of the structure resulting from a deformation of the layer is obtained based on the obtained predominant frequency and amplification factor of vibration of the top surface of the layer of the structure and on the height of the layer of the structure. This seismic vulnerability index is multiplied by an assumed seismic acceleration so as to obtain a maximum shear strain of the layer of the structure upon being subjected to an earthquake.
    • 为了确定结构的地震脆弱性,将振动传感器放置在结构的层的顶表面和结构附近的地表面上,以便记录振动。 地震脆弱性数据处理器基于记录在结构层的顶表面上的振动与记录在地面之间的振动之间的光谱比,假定结构层的顶表面的振动的传递函数,由此 获得结构层的顶表面的振动的主要频率和放大系数。 基于获得的结构层的顶表面的振动的主要频率和放大系数以及结构层的高度,获得由层的变形产生的结构层的结构层的地震脆弱性指数 。 该地震脆弱性指数乘以假定的地震加速度,以便在遭受地震时获得该结构层的最大剪切应变。
