Blast Analysis of a Bridge with AASHTO Type VI Girders Using CSI Bridge
Protection of bridges from blast load due to terrorist attacks or accidental explosions is necessary. For this we require to study the performance of a bridge when blast loads are applied above the deck slab. The research presented in this thesis represents the response of AASHTO type VI girders of …

Probabilistic models for blast parameters and fragility estimates of steel columns subject to blast loads
… probabilities of steel columns subject to blast loads. The framework considers the uncertainties in the blast phenomenon, the demands imposed on the column, and the capacities of the column for the limit states of flexure, local buckling and global buckling. As part of the work, we propose …

Behavior and design of steel-plate composite (SC) walls for blast loads
… have historically been the preferred choice for blast resistant structures because of their mass and the ductility provided by steel reinforcement. Steel-plate composite (SC) walls are a viable alternative to RC for protecting the infrastructure against explosive threats. SC structures consist of …

The effect of stand-off distance on the failure of thin plates subjected to blast loads
… of fully clamped circular plates subjected to blast loads. The experimental procedure consists of creating a blast load using disc shaped plastic explosive mounted onto a tube of required length. The length of the tube is the stand-off distance. Different lengths of tubes are used ranging from …

Tools for the formation of optimised X-80 steel blast tolerant transverse bulkheads
… effort focussed on the development of X-80 steel blast tolerant transverse bulkheads. Unfortunately, due to the Australian Maritime Engineering Cooperative Research Centre not being re-funded after June 2000 and other project factors, the planned blast tests were not conducted, hence this research …
