Abstract

There are limited studies that directly correlate the increase in structural column capacities in resisting the blast loads with the strengthening measures, such as the strengthening materials, layers of Fiber Reinforced Polymer (FRP) applied and types of epoxy used. In this paper, numerical analyses of dynamic response and damage of reinforced concrete (RC) columns strengthened with Carbon Reinforced Polymer (CFRP) are carried out to examine the structural response under different blast loads. The research illustrated that the effective strengthening can be achieved with FRP wraps to increase column's shear capacity and three longitudinal composite strips on each of the column's face to increase its flexural capacity. LS-DYNA software is used to carry out the structural response analysis and the results obtained are also used to construct the Pressure-Impulse (P-I) curves of the strengthened columns. These P-I curves can be used to assess the performance of FRP strengthened RC columns under various blasting scenarios.
