Seismic Behavior Analysis of Gate Dam

The mode-superposition response spectrum method was applied to calculate structure seismic action of a gate dam. Based on the analysis of the structure performance,we paid special attention to the stress state of the key parts. The results showed that the displacement and stress of the whole structure were related to the direction of earthquake excitation. As large principal tensile stress and principal tensile stress area appeared in steep change points of geometry shape and material, special attention should be paid when calculating anti-seismic checking and reinforcement arrangement. The displacement, stress and the stability against sliding should meet the standard requirements.

Key words:mode-superposition response spectrum method,seismic performance,finite element method
