Abstract
This study aims to enhance the performance of explosion-proof doors by analyzing the structure, arrangement, and features of their stiffeners. Numerous numerical models were developed to assess how the above parameters affect the performance of rectangular doors under blast loads. The modeled doors consist of stiffeners on their inner face that help them absorb energy and reduce displacement. An optimization process was also carried out to determine the best number and thickness of stiffeners that can minimize displacement while optimizing steel consumption. The analysis revealed that using a non-parallel stiffener can decrease the displacement of the door's center by about 30% while maintaining the same weight. Moreover, the optimal number of stiffeners depends on their thickness. If the thickness of the stiffener is less than 25% of the door panel's thickness, seven stiffeners should be used. If the thickness is between 25% to 40%, five stiffeners are optimal. When the thickness ranges from 40% to 60%, three stiffeners are sufficient, and if the thickness is greater than 60%, one stiffener will provide the best functionality for the explosion-proof door.
