Summary: The Blast Protective Design Capstone has been working to improve the modeling tools readily available to NAVFAC EXWC engineers that will enable deeper levels of performance-based design of blast loaded reinforced concrete structures. Current code provisions use flexural member support rotations as a key parameter for assuming different member damage levels, and consequently, levels of protection. Some current modeling procedures do consider ductility demand on a material, but they do not provide insight into the material’s performance in terms of stress and strain. The team has built a custom suite of modular Mathcad Prime sheets/tools that enables efficient Single Degree of Freedom (SDOF) modeling and prediction of material strains for use as a refined member damage criteria. Additionally, more advanced nonlinear modeling concepts were investigated for incorporation into the SDOF modeling.
