Dynamic Shear Resistance of Thin-Webbed Reinforced Concrete BEAMS
Experiments were performed to obtain information on the dynamic shear and diagonal tension resistance of reinforced concrete I-beams constructed with welded-wire fabric as web reinforcement. These experiments were in support of the ultimate objective of the project, which is a formulate design criteria for thin-shell concrete structures to withstand dynamic loading such as is produced by the detonation of a nuclear weapon. Under uniformly distributed loads, the dynamic diagonal tension resistance of the beams was found to be significantly greater than the static diagonal tension resistance. The increase in resistance was attributed to the increase in tensile strength of concrete under rapid stressing. The ultimate shear resistance of the beams could not be precisely determined from the tests because only three of the beams failed in shear. However, evidence was found that the dynamic ultimate resistance of such beams is only slightly greater than the static ultimate resistance. (Author)
