A New Generic Approach for Assessing Blast Effects on Reinforced Concrete Members

Funding: 2015: $60,159

Project Member(s): Wu, C.

Funding or Partner Organisation: Australian Research Council (ARC Discovery Projects)

Start year: 2015

Summary: A framework allow for both flexural and shear response analysis using a new segmental approach is developed in this proposal. A blast test program is designed to validate the framework for reinforced concrete members. The validated framework is then used to derive normalized pressure impulse programs for reinforced members in unconfined and confined spaces. The proposed research will provide design engineers guidelines for reliably and quickly assessing the effect of different kinds of blast loads on different types and properties and geometries of reinforced concrete structural members, saving computation time and efforts while providing increased realism and accuracy.
