RR404 - Pulse pressure testing of ¼ scale blast wall panels with connections - Phase II

A detailed experimental and numerical study of 1⁄4 scale stainless steel blast wall panels and their connections under pulse pressure loading has been conducted at the University of Liverpool. The panel design was based on the deep trough trapezoidal profile with welded angle connections top and bottom and free sides. Three types of panel/connection system were studied, namely a short, medium and long welded angle connection to compare the influence of the angle length. Large permanent plastic deformations were produced in the panel/connection system without rupture. Phase I established that modelling the support correctly is fundamental to the response of the blast wall and can significantly affect its ultimate capacity.
