Evaluation of ASCE-41 Modeling Parameters and Acceptance Criteria through an RC Building Case Study

摘要

The ability to simulate the nonlinear dynamic response of RC buildings up to significant levels of component damage is of fundamental importance to evaluate their expected performance for different levels of seismic hazard. In the United States there is an increasing reliance on the provisions in the ASCE-41 standard for developing models to simulate the nonlinear response of structures during strong earthquakes. This paper presents fragility relationships from incremental dynamic analyses performed with ASCE 41 modeling parameters on a non-ductile reinforced concrete building located in Van Nuys, California, that was instrumented during several earthquakes. Analyses were performed for the ground motion sets in FEMA P695 and ground motions from earthquakes recorded at the building site. Results from incremental dynamic analyses are used to evaluate modeling parameters and acceptance criteria in ASCE 41 as well as the calculated intensity measure at collapse.
