The simplified models available in the literature for the seismic analysis of MSC are listed in Table 3. Gunawardena et al. [104] used spring elements to model the horizontal end plate bolted connection using SAP2000 and RUAUMOKO 3D. The vertical joint was modelled by beam elements considering ...
(1)振型型分解法,首先是进行模态分析,有多少个动力自由度,理论上就有多少个模态,相应的有多少个周期(频率),及振型。 (2)振型向量关于质量矩阵及刚度矩阵正交。因此,无阻尼运动方程可以实现解耦,将耦合的运动方程,解耦为多个广义单自由度运动方程。
