| Research Abstract |
To investigate punching shear strength of reinforced concrete slab, two types of specimens are tested: specimens with/without slits. In a specimen, slits are used so as to resist bending moment only by the torsional resistance of concrete slab. The test result shows that the maximum shear stress used in the Japanese standard is appropriate. However, a specimen without slits show that the area resisting torsion is larger than that assumed in the Japanese standard. Based on the test results, a method to evaluate the punching shear strength of concrete slab is proposed.
