摘要:
提出了使用无条件稳定显式Chang积分算法的剪切型子结构振动台试验方法,包括子结构定义及试验流程。进行某12层剪切型结构的整体结构及子结构方法的时程分析,整体结构分析结果作为子结构方法分析结果的参照。对于无时滞的情形,采用两种误差指标来量化子结构方法结果的准确性,研究了积分时间步长及时程分析类型对结果的影响。最后,考虑时滞对子结构方法结果的影响。结果表明:当系统不存在时滞时,即便在较大的积分时间步长的情况下,子结构方法的分析结果依然可以较好地吻合整体结构的分析结果;当系统存在时滞时,时滞对子结构方法结果的准确性产生不利的影响。
Abstract:
A shear-type substructure shaking table test method, which includes the substructure definition and the testing flowchart,was proposed using the unconditionally stable explicit Chang algorithm.Complete structure time-history analyses of a certain 12-story shear-type structure were conducted and used to provide a reference to the results using the substructure method.For the caseof the system without time delay, two error indicators were adopted to quantify the accuracy of the substructure method. The influences of the integration time step and the time history analysistype on the numerical results were studied.Finally, the influence of the time delay on the substructure method results was taken into consideration. The results show that for the case of the system without time delay, the analytical results obtained from the substructure method agree well with those from the complete structure analyses even if the integration time step is relatively large. As for the case of the system with time delay, time delay has negative impact on the accuracy of the results obtained from the substructure method.
