Research Institution

To achieve a superior, more accurate simulation model for next generation progressive collapse of buildings, Applied Science International proposes use of the Applied Element Method (AEM) as the core solver of a fast running software tool for evaluating structural integrity following a blast or other extreme loading event. Due to its simplicity in modeling, speed of computing, constitutive models, and visualization of the outcome, AEM enables practicing engineers to conduct the complicated analysis usually done by specialists. In Phase I, ASI will examine the accuracy of structural responses when compared to live blast test data provided by the Defense Threat Reduction Agency (DTRA) and simulations based on DTRA’s blast model built by Applied Research Associates (ARA). This will determine validation or improvement of the blast wave-structural interaction and structural response for accurately predicting component behavior. This comparison will also include the time needed to prepare and run models, accuracy of predicting damage levels and locations, and determination of fragmentation and debris behavior. AEM solver performance of structural and non-structural components will be examined and include analysis of selected experiments that may include reinforced concrete, steel, composite columns, reinforced concrete slabs, brick walls, and glass windows.
