Development of Nonlinear Analysis Method to Simulate Nonlinear Behavior of RC Walls in RC Wall-Frame Buildings Suffering Damage from Earthquake and Subsequent Tsunami

TL;DRAbstract

After the 2011 Great East Japan earthquake and tsunami, overestimated and unexpected damage, such as overturned buildings in Onagawa town, was a result of earthquake and subsequent tsunami.In the future, more severe and different unexpected damage by earthquake and subsequent tsunami may occur in the Tokai, Tonankai, and Nankai region.The occurrence of building overturning in Onagawa town encouraged the author to focus on structural damage of RC wall-frame buildings from earthquake and subsequent tsunami.Previously, macro plate model had been proposed to simulate earthquake response of a wall member in RC walls.In this research, macro plate model was proposed to simulate tsunami response as same as nonlinear analysis in earthquake response.Since macro plate model had been developed based on nodal displacement, distributed force from tsunami was converted to nodal force in order to evaluate out-ofplane strain using average curvature.Then, nonlinear analysis of out-of-plane behavior was
