【摘要】 使用有限元软件Etabs对基础隔震结构在不同场地类别条件及不同支座布置方式下的力学性能进行分析,发现结构无论在任何场地类别条件下,四周布置铅芯橡胶支座、中间布置天然橡胶支座这种布置方式更为适宜.从能量的角度分析,在同一加速度峰值的影响下,在软土地基中的隔震效果最明显.更多还原

【Abstract】 The finite element analysis software ETABS was used to analyze the mechanical properties of the base isolation structure under different site classification and different bearing arrangement. It is found that the arrangement of lead-core rubber bearings around the structure and natural rubber bearings in the middle is more appropriate regardless of the type of site conditions. From the point of view of energy, the isolation effect is the most obvious in soft soil foundation under the influence of the same peak acceleration.更多还原
