Performance-Based Analysis of a Reinforced Concrete Shear Wall Building

Abstract

In this thesis, a special reinforced concrete shear wall building was designed per ASCE 7-05, and then the performance was investigated using the four analysis procedures outlined in ASCE 41-06. The proposed building was planned as a 6-story office building in San Francisco, CA. The structural system consisted of a two-way flat plate and reinforced concrete columns for gravity loads and slender structural walls for seismic loads. The mathematical building models utilized recommendations from ASCE 41-06 and first-principle mechanics. Moment-curvature analysis and fiber cross-section elements were used in developing the computer models for the nonlinear procedures.The results for the analysis procedures showed that the building met the Basic Safety Objective as defined in ASCE 41-06. The performance levels for the nonlinear procedures showed better building performance than for the linear procedures. This paper addresses previously found data for similar studies which used steel special moment frames, special concentric braced frames, and buckling restrained braced frames for their primary lateral systems. The results showcase expected seismic performance levels for a commercial office building designed in a high seismicity region with varying structural systems and when using different analysis procedures.

Evaluating Seismic Performance in Reinforced Concrete Buildings with Complex Shear Walls: A Focus on a Residential Case in Chile

“…This approach intends for the structure to accommodate seismic displacements with pre-dictable and desired behavior, maximizing deformation and energy dissipation capacities while effectively reducing seismic demands on the structure [40]. Analogously, this concept likens the structural system to a chain that remains ductile overall if the weakest link is intentionally designed to be ductile, thereby maintaining integrity even when not all links share this property [41][42][43].…”

Seismic Performance Study on Rc Wall Buildings From Pushover Analysis

“…Presence of openings, irregularities, unusual slenderness and lack of proper ductile reinforcement are likely to cause failures in RC walls. Many such instances of RC wall failures (Fig-2) can be found during past earthquakes [2]. Also, there is acute shortage of codal provisions and specifications for the seismic resistant design of RC wall buildings.…”

Evaluación comparativa mediante diseño basado en el desempeño de un edificio estructurado en base a muros

“…Asimismo, se unió a esto la necesidad de los tomadores de decisiones de cuantificar el beneficio de invertir en una estructura sismorresistente superior, analizando a partir de su desempeño los daños y pérdidas que podría sufrir en eventos durante su vida útil (Dabaghi et al, 2019;Abdullah y Wallace, 2020;Kolozvari et al, 2018;Arifin et al, 2021;Ji et al, 2018). De igual manera, está la preocupación de la sociedad acerca de la seguridad y confiabilidad del diseño frente a los sismos fuertes, buscando en si el resguardo de vida de los ocupantes, el continuo funcionamiento de servicios esenciales y asegurar la contención en las instalaciones que manejan elementos peligrosos, entre varias otras funciones específicas (Abdullah y Wallace, 2020;Zhong et al, 2021;Vielma et al, 2010;Hagen, 2012).…”
