Abstract
A series of field tests was carried out at the BakerRisk test site in San Antonio, TX, on 1/4 scale stainless steel blast panels. The panel design was based on a deep trough trapezoidal profile with flexible welded angle connections. The loading applied to the test panel was a shocked pressure pulse representative of an air blast. The aim of this work was to investigate the influence of the connection detail on the overall performance of the panel/connection system under shocked pressure loading. The data were also used to develop appropriate analytical and finite element numerical models for correlation with the test results. Large permanent plastic deformations were produced in the panel without rupture. The work has shown that the connection detail can significantly influence the response and blast resistance of the panel to extreme pressure loading. This, in turn, should lead to more economical design.
