摘要：
Currently, there are hollow spaces in stiffened steel anti-explosion doors, which will reduce their anti-explosion capacity. To solve this problem, a novel steel anti-explosion door filled with reactive powder concrete (RPC) is designed. An approach for modeling steel-RPC anti-explosion doors under blast load was presented using the software LS-DYNA. The validity of the model was established by comparing displacement predictions from numerical analysis with relative test results. Results from the analysis of dynamic response indicated that the anti-explosion capability of the steel-RPC anti-explosion door is better than those of the steel anti-explosion door and the steel-concrete anti-explosion door. Results from the parametric analysis of dynamic response indicate that the dynamic response of anti-explosion doors is decreased significantly by increasing the number of ribs and the plate thickness. The thickness of ribs and RPC strength have minor influences on the dynamic response of anti-explosion doors. Design suggestions of steel-RPC anti-explosion doors with various dimensions and anti-explosion ratings are provided based on numerical results. It can be served as reference for anti-explosion projects. © 2016, Editorial Office of Journal of Building Structures. All right reserved.
