Abstract
Under extreme loading condition, a shelter will provide a safe place to protect people from injury caused by blast wave and fragments. In order to save resource and reuse waste materials, a new design concept for blast protection shelter was explored. The new construction was composed of I-section steel panel or C-channel steel panel filled with recycled concrete aggregate. The compaction process of the recycled concrete aggregate filled in the steel construction was experimentally investigated. A single storey shelter based on the proposed design concept was numerically simulated by using LS-DYNA software. In the 3D numerical model, three walls were designed using I-section steel and one wall using C-channel steel, and all of the four walls were filled with recycled concrete aggregate. The penetration analysis was done by using ConWep. Some penetration tests were also carried out by using a gas gun. It is found that the proposed shelter based on the design concept is effective for blast protection.
