COLLABORATIVE RESEARCH AND DEVELOPMENT (CR&D) Delivery Order 0064: Advanced Computational Dynamics Simulation of Protective Structures Research
Abstract
This research in support of the Air Force Research Laboratory Materials and Manufacturing Directorate was conducted at Wright-Patterson AFB, Ohio from 21 December 2006 through 1 February 2008. This task defined the effects of extreme dynamic loading on civil structures reinforced with advanced materials. Due to the nonlinear behavior of concrete masonry walls, the use of advanced simulation techniques provides advantages over experiments for full understanding of their structural responses under explosive loads. In this study, several finite element models were developed according to blast test conditions, and analyzed using LS-DYNA explicit code. Input sensitivity studies were conducted to investigate the variations of a wide range of parameters on wall deformations, damping coefficients, boundary conditions, and arching action. The effort has led to cost effective analysis techniques for use by structural engineers in designing membrane retrofit concrete masonry walls subjected to blast loads. This report summarizes the simulation methodologies, challenges, techniques, and comparison to full-scale dynamic tests for membrane retrofit concrete masonry walls.
