Composite Column and Wall Systems for Impact and Blast Resistance

Short description

Composite steel-concrete members provide ideal systems for impact and blast resistance, which have not been utilised to their full potential due to the lack of appropriate investigations, particular when using high-strength materials. This programme has developed design guidance, for members incorporating conventional and/or high-strength materials, under extreme impact and blast loading. The work has involved experimental and theoretical determination of bearing and rotational capacity, coupled with complementary dynamic tests and nonlinear analyses. Evaluation of residual strength/damage enables also assessment of interaction with probable subsequent loading scenarios, such as ensuing fires, with a view to provide performance-based design procedures.
