Abstract

Full-scale blast arena tests involving concrete-filled rectangular hollow sections (RHS) have been completed. The tests utilized two RHS sizes having width-to-thickness ratios of 15 and 24, both filled with non-shrink, cementitious grout, that were each tested at two standoff distances. The cold-formed RHS members were subjected to air blast loading and their flexural response was measured. The data obtained during the full-scale blast tests was used to validate numerical models of the composite RHS elements. For this research study, the explicit finite element program LS-DYNA has been used to develop the model. LS-DYNA incorporates features such as strain rate-dependent material properties that are included in the numerical models. Results thus obtained from the numerical models are compared herein to the results of the full-scale blast arena tests.
