A new blast-resistant design method of rc members and its application in performance based blast-resistant design procedure

Anotace: Design method is very essential and important for engineers. Present study proposes a new blast-resistant design method. First, two common used blast-resistant design methods are discussed. By analyzing the disadvantage of the common procedures, a new blast-resistant design method is proposed. The new design method has less design loops, as well as good control of the maximum displacement and ductility. Then, a dimensionless P-I diagram, which is convenient for design, is proposed based on the new design method. Finally, the new blast-resistant design method is applied in the performance-based blast-resistant design (PBBD) procedure described using a detailed design example. The design example shows that the proposed design method could be easily applied in the PBBD procedure.
