Experimental Study on Shear Capacity of Embedded Composite Beam with Notched Web

Abstract:

Based on a test of 6 shear specimens,a research was made into the bearing capacity and failure process of the embedded composite beam. Test results show that the shear bearing capacity of the beam is influenced by the section of steel web, the section of concrete flange, the concrete grade and the shearspan ratio of concrete flange. Based on the test results and parametric analysis, the formulas to calculate the shear capacity of the concrete flange were developed. A simplified calculation method of shear bearing capacity was developed by taking the possibity into consideration that the shear bearing capacity of the beam may decrease when it is subjected to a moment and shear force.A study of the bearing capacities of the notched web connector in embedded composite beams shows that the connector is of a higher shear bearing capacity and the full shear connection can be easily achieved in embedded composite beams.

Key words:embedded composite beam with notched web; shear test; shearspan ratio; shear capacity
