A Wooden House Cluster Model for Earthquake Damage Estimation by Nonlinear Response Analyses

Strong Ground Motions and Damage Conditions Associated with Seismic Stations in the February 2011 Christchurch, New Zealand, Earthquake

“…We adopted the Takeda Model ( Figure 5A; Takeda et al 1970) for RC build- ings and the Modified Takeda-Slip Model ( Figure 5B; Iizuka and Sakai 2009) for wooden houses as hysteresis models. We set these model parameters, as shown in Table 5, to assume general buildings and houses and an allowable ductility factor of 6, given the heavy damage to buildings Sakai and Iizuka 2009). Figure 6 shows the required strength (base shear coefficient) spectrum of REHS compared with that of Takatori, Fukiai, and JMA Kobe.…”
