Physics-based probabilistic demand model and reliability analysis for reinforced concrete beams under blast loads

This paper proposes a general physics-based probabilistic demand model for the reliability analysis of reinforced concrete (RC) beams under blast loading. The formulation of the proposed demand model builds on a computationally convenient representation of the governing physical laws from structural dynamics and adds a correction term and a model error. Specifically, the proposed demand model starts with predictions from a generalized...
