根据能量法原理，列出钢筋-沥青复合隔震层在整个地震过程中的能量平衡等式；结合不同隔震层高度、不同地震波输入和不同加速度输入下钢筋-沥青复合隔震层的振动台试验数据，从总输入能、变形能、动能与阻尼耗能几个方面对隔震层试件进行能量平衡分析，绘制试验过程中的能量时程曲线。研究结果表明：相同高度和加速度输入条件下，阻尼耗能和塑性变形能随加速度的增加呈非线性增大；阻尼耗能在振动台试验中占总输入能量的60％～70％，对结构耗能起主导作用，说明钢筋-沥青复合隔震层具有较好的耗能特性；同时误差分析表明，该能量分析方法可行。

According to the principle of energy method,energy equilibrium equation of steel -asphalt compos-ite isolation layer during the whole earthquake time history was presented.The energy equilibrium analysis of iso-lation layer specimen was carried out in aspects of total input energy,deformation energy,kinetic energy and damping energy based on shaking table test data of steel-asphalt composite isolation layer under the conditions of different layer heights,seismic wave inputs and acceleration inputs,and the energy time history curves were plotted during the test.The results show that,with the same heights and acceleration inputs,damping energy dissipation and plastic deformation energy increase non-linearly as the acceleration increases.Damping energy dissipation in the shaking table test accounts for 60% ~70% of total input energy,taking a dominant position on structure energy dissipation,which indicates good energy consumption characteristics of the steel -asphalt composite isolation layer.Meanwhile,the error analysis shows that this energy analysis method is feasible.
