dc.description.abstractDamage assessments have shown that a significant number of older reinforced concrete buildings constructed in North America before 1971 have suffered severe structural damage as a result of strong earthquakes. The level of damage in some of these buildings has motivated researchers to develop new and improved modeling techniques that can be used to simulate their behavior up to severe levels of distress with the goal of assessing the risk of collapse and threat to human life. This study is focused on evaluating recently-adopted modeling parameters and techniques to simulate the response of an instrumented building located in Van Nuys, California. The building is a seven-story non-ductile reinforced concrete frame building, which suffered extensive damage during the 1994 Northridge earthquake Blume (1973). The objective of this study is to evaluate the calculated response of this particular reinforced concrete structure using a computer model based on standardized nonlinear modeling parameters. By simulating the response of this building for an earthquake in which the both the acceleration response at several stories and the damage are documented Blume (1973), it will be possible to evaluate the outcomes obtained when standardized nonlinear modeling parameters are used to simulate the response of a large system. This is a question of great significance because practicing engineers rely on these parameter to evaluate the seismic hazard in building structures that do not comply with modern seismic codes. The study focuses on use of inelastic modeling parameters for structural components established in the ASCE 41-13 Standard ASCE-41 (2013). Both nonlinear dynamic and nonlinear static (pushover) analysis were performed using the computer program OpenSees (2006). OpenSees, the Open System for Earthquake Engineering Simulation, is an object-oriented software framework developed at the Pacific Earthquake Engineering Center (PEER). The results of nonlinear static and dynamic analysis were evaluated in terms of the hinge distribution for the collapse mechanism, the base shear force, and the drift ratio associated with the collapse of the building. All of these performance measures are affected by a number of modeling parameters, such as inelastic rotations corresponding to shear and axial failure, the effective stiffness, and the material strengths.
