Simplified modeling of non-rectangular RC structural walls

To facilitate development of performance-based engineering (PBE), a simplified modeling approach was developed for use by structural engineers to predict the load-deformation response of structures incorporating walls. In addition to determining the load-displacement response of walls, it associates predicted strain levels with expected degrees of damage, such as cracks requiring repair, concrete cover spalling, and imminent failure. The predicted load-displacement response is separated into components of deformation due to flexure, shear, and strain penetration to give further indication of types of expected damage, such as flexural or web shear cracks. To investigate the robustness of the model relative to the prediction of the force-deformation response of wall systems, results were compared to the response of several specimens tested by other researchers.
