Abstract
A new steel-concrete composite beam with notched web of inverted T-shaped steel section is proposed in this paper. This composite beam is composed of concrete slab and inverted T-shaped steel beam. Experimental studies on the bend and shear behavior of the composite beam are conducted. Four specimens are tested to investigate the bend behavior of the novel composite beam, and the formula for predicting the bend capacity is proposed and verified by comparing the results between predicted with the formula and the measured from the tests. Six specimens are also tested to study the shear behavior and the formula for estimating the shear capacity of the novel composite beam is recommended on the base of the test results. The formulas proposed in this paper may be employed to estimate the bend and shear capacity of the composite beam with notched web of inverted T-shaped steel section for application in practice.
