结合工程实例对隔震结构设计中的嵌固刚度比问题进行分析,认为嵌固验算位置选取不合理将使嵌固刚度比要求失去实际意义;对隔震支座位移计算的地震输入及位移控制方法进行探讨,认为采用单向位移的控制方法偏不安全;对隔震支座拉应力计算相关问题进行分析和探讨的结果表明,在支座出现拉应力后,对隔震层的内力的计算将进入复杂的非线性阶段,如果计算模拟不得当将使支座拉应力计算结果出现严重偏差,影响隔震方案。
Combined with engineering examples, the problem of embedded stiffness in the design of isolated structure is analyzed. It is considered that the unreasonable selection of embedded verification position will make the embedded stiffness less practical than the requirement. The seismic input and displacement control Method, it is considered unsafe to adopt the control method of unidirectional displacement. The analysis and discussion on the calculation of tensile stress of isolation bearings shows that the calculation of the internal force of the isolation layer after the tensile stress of the support Will enter the complex non-linear phase, if the calculation is not properly simulated will make the bearing tensile stress calculation results serious deviation, affect the isolation program.
