摘要
以直流电压发生器结构的抗震计算为例,讨论了采用不同模型对双塔结构地震反应计算结果的影响.数值分析的结果表明:当采用单体模型计算时,主结构的计算结果与整体模型的计算结果差异不大,而从结构采用单体模型计算时,地震反应的数值较整体模型计算结果大,说明当主从双塔结构作为整体抵抗地震作用时,主结构会分担一部分作用在从结构上的地震荷载.通过输入不同场地类型地震波的双塔结构地震反应计算,讨论了双塔式直流电压发生器结构采用单体结构计算模型时应取的修正系数.
Pertaining to the anti-seismic analysis for a direct current voltage generator, the seismic response analysis is adopted for a twin-tower structure based on various models. It is observed that, while applying the single-body computation, the computational results between the primary tower and entire structural model are quite similar, thus seismic response values of the secondary tower are larger than those of the structural model. This is because the primary sidering various on-site seismic structure shares the seismic loading acting on the secondary structure. By conwaves, different correction coefficients are postulated for single-body computational models of twin-tower direct current voltage generator structures.
