Shear capacity of reinforced concrete beams under complex loading conditions

Abstract

In this paper, the shear capacity of reinforced concrete specimens without shear reinforcement loaded under multiple point loads with both continuously and simply supported boundary conditions is investigated. Various experiments have been carried out in the laboratory. The test results are compared with those obtained on similar specimens loaded by a single point load in the same research project. Besides, the test results are compared with design formulas suggested in design codes such as Euro-code and fib Model Code 2010. Several recommendations are given with respect to the tested loading conditions.
