Abstract:This paper describes a simplified methodology to design masonry and concrete walls retrofitted with fiber-reinforced polymer (FRP) products to resist blast load. The wall is analyzed as an equivalent single-degree-of-freedom (SDOF) system responding in flexure to a spatially uniform blast load. The methodology provides specific guidance on how to define all the relevant properties of the equivalent SDOF system based on flexural and shear properties of the retrofitted wall using equations similar to those for static properties of retrofitted walls in ACI 440.2R responding in flexure. The methodology also provides response limits that give correlations between the calculated maximum dynamic response and the corresponding blast damage level to the retrofitted wall. The response limits can be used to design a blast resistant wall for a given amount of acceptable damage.
This paper discusses the SDOF-based procedure, summarizes available blast test data on retrofitted walls, and shows comparisons between maximum deflections calculated with equivalent SDOF models of the test walls and measured values. Also, the development of the response limits is described with photographs of observed wall damage levels in shock tube tests.
