大跨度T构连续梁振动模态分析

On analysis of vibration mode in large-span T-frame continuous beam

指出模态分析是进行抗震分析所必需的前期分析过程,建立了T构连续梁系统的振动分析模型,并对该系统进行了模态分析,得到了该系统的振动动力特性(固有频率、振型),为该结构的抗震分析提供一定的理论依据。

The paper points out the mode analysis is the necessary analysis process in early period in seismic analysis, establishes the vibration analysis mode in T-frame continuous beam system, has the mode analysis in the system, and points out the vibration dynamic characteristics of the system, so as to provide some theoretical reference for the seismic analysis of the structure.
