Abstract

Full-scale, blast arena testing has been performed on cold-formed rectangular hollow section (RHS) members in flexure. RHS members with width-to-thickness ratios of 15 and 24 were tested at two scaled distances. These tests were heavily instrumented to gather detailed information on the behaviour of both the RHS members and the air blast wave profile. Additionally, material testing was performed to confirm the properties of the steel. Data from the blast arena testing is used to validate predictive and numerical models. One modeling method in blast-resistant design is explicit finite element (FE) analysis. ANSYS LS-DYNA has been used to numerically model the RHS members and to subject them to blast loading profiles similar to those from the arena tests. The LS-DYNA models incorporate measured test parameters and include strain-rate-dependent properties for the steel. A comparison between data obtained from the field blast tests and the model is then presented herein.
