Behavior of Building Structure Subject to Tsunami Load

Abstract This study aims to analyze of the structural behavior two-story building under combination earthquake forces and tsunami hydrodynamic forces, with model variations included percentage wall’s opening thickness. The 3-D modeling buildings were conducted in this using software SAP 2000; first consisted wall panels openings 0% (PD0), 25% (PD25), 35% (PD35), 50% (PD50), while second 150 mm 250 In addition, force predicted by numerical simulations based on Smoothed Particle Hydrodynamic (SPH) was compared that semi-empirical design equations. results panel show greater opening, smaller load can be carried out structure hence, lesser stresses wall. increase building’s thickness from loads decreased stress walls, moments transverse forces. Conversely, tensile shear walls increased due loads. comparison shows maximum SPH generally higher
