Abstract
Reinforced concrete slabs are one of the most frequently used blast-resistant structural elements. The RC slab behavior under blast loading is nonlinear and complicated. The maximum slab displacement differs by the amount of explosive, support conditions, steel ratio, etc. In the present paper, the maximum deflection of two-way RC slabs subjected to blast loading is studied. To this purpose, the RC slabs are replaced by SDOF equivalent systems with bilinear stiffnesses through determining the equivalent mass and stiffness. The results of comparing the analytical proposed method with the nonlinear analysis by the LS-Dyna software and the method specified by UFC 3-340-02 guideline show that in most loading conditions and slab geometries, the output of proposed method is more economical than the UFC guideline. In addition, whilst the UFC method is not applicable for all time ranges, the proposed method can determine the structural element response at any time range.
