Title: Review of Past Performance and Further Development of Modeling Techniques for Collapse Assessment of Existing Reinforced Concrete Buildings
Published: January 23, 2014
Abstract: The first phase of work of the Program Plan, documented in this report, included the identification of critical deficiencies, refinement of the list of common deficiencies, and development of collapse mitigation strategies for older reinforced concrete buildings. To facilitate the anticipated analysis program that is envisioned for developing collapse indicators, this phase also included identification of the latest analysis, modeling, and collapse simulation techniques for reinforced concrete components and systems. Because analytical capabilities are rapidly evolving, and the Program Plan includes several research initiatives related to improving collapse simulation that won't be completed for many years, a key strategy in this effort was the conduct of a Collapse Simulation Workshop. In this workshop, leading researchers and practitioners were assembled to review and discuss current state-of-the-art techniques, and to define recommendations for analyzing and simulating degrading response of reinforced concrete systems, which can be used in the near term.
