With funding from the Network for Earthquake Engineering Simulation Research (NEESR) program of the National Science Foundation, seismic behavior of rectangular cast-in place concrete walls and an equivalent precast wall system has been studied. In addition, complex behavior of T-shaped concrete walls subjected to multi-directional loads has been investigated. The rectangular cast-in-place walls has focused on the influence that the anchorage of the wall longitudinal reinforcement into the footing has on the in-plane response concrete walls while the precast system was motivated to produce a low-damage self-centering wall option with superior seismic response to that observed for the cast-in-place walls. The T-walls were used to investigate their complex seismic behavior and the ability to predict their behavior under multi-directional loads. All of the investigations included large-scale tests and advanced analytical simulation based on fiber-based or equivalent finite element models.
The presentation will focus on the motivation for the study, lessons learned, advancements made to simulation capabilities, and recommendations for design and analysis. It will be concluded with some details of an ongoing NEESR research on precast concrete walls.
Bio: Dr. Sri Sritharan is the Wilson Professor of Engineering and Associate Chair of the Department of Civil, Construction and Environmental Engineering at Iowa State University. Sri’s research expertise includes earthquake-resistant design of structures, precast structural systems, soil-foundation-structure interaction and Ultrahigh Performance Concrete. Sri has engaged in NEES research since its inception and an active member of several professional societies. He is the current chair of the American Concrete Institute Committee on Earthquake-Resistant Concrete Bridges and serves on PCI’s Research and Development and Piling committees. Sri has won several awards including PCI’s Young Educator Achievement Award and Martin P. Korn award as well as the Best IT Innovation award from NEES.
