The nonstationary random response of elastic circular arch under horizontal seismic excitation was studied by the method combining the pseudo-excitation algorithm with Galerkin algorithm.
应用虚拟激励法与伽辽金法相结合，分析弹性圆拱在非平稳水平随机地震作用下的随机响应问题。

Secondly, a classical elastic flexural-torsional buckling tests on arch is introduced, which is simulated by shell element SHELL63 and beam element BEAM189 of commercial software ANSYS.
The paper introduces uneven load in the arch-back to calculate the internal force in the linking of an interval tunnel for a metro line by theoretical formula and elastic uniform rigidity ring model.
