• Fundamental study on torque shear test for evaluation of bonding strength between steel and concrete

抄録

For better design and construction of steel-concrete hybrid structures, it is important to evaluate strength and behavior of the joins. In this study, new torque shear tests were carried out to develop a test method for shear strength between steel and concrete. It has a steel cylinder buried on mortar block, driven by torque arms, and the interface has no end and no stress concentration. The devices were improved and fundamental influences of the specimen size, loading parameters and cracking occasion were examined. As the result, it became clear that additional normal loads on torque arms have little influence and cracks initiate on the surface of the mortar block play important role in the test.
