In case the height span ratio is comparatively big, the shear strain and the moment of inertia of a beam bridge must be taken into consideration under vertical seismic force. In this study,we give the vibrational solution for such a bridge.是什么意思_In case the height span ratio is comparatively big, the shear strain and the moment of inertia of a beam bridge must be taken into consideration under vertical seismic force.
