SEISMIC BEHAVIOR OF AAC STRUCTURES DESIGNED WITH DIFFERENT FLEXURAL CAPACITIES
The behavior of three structures of autoclaved aerated concrete (AAC) designed with different force-reduction factors is evaluated in terms of maximum displacement ductility and drift ratio demands. The maximum demands are obtained from nonlinear analyses carried out using earthquake ground motions, representative of the Mexico City firm soil, together with hysteretic models obtained from laboratory tests results. Earthquake ground motions were scaled by making the corresponding response spectra to represent in average the design spectrum. Based on the nonlinear analyses results and assuming a maximum displacement ductility capacity of 3.5, a value of the force-reduction factor of 1.5 and a value of the displacement amplification factor of 2.0 are obtained. It is concluded that those values are adequate for the seismic design of the AAC structures studied.
