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 ...

Background: A steel frame system becomes structurally less efficient when subjected to large lateral loads such as a strong wind, earthquake. Many research efforts have been made develop more structural systems with better resistance against loads. Methods: An attempt is in this direction by both analytical and experimental studies. bare framed model of size 4m x4m chosen for G+2 storey columns...
