In the present study, the effect of using reinforced concrete column capital on the punching shear strength of flat slab was investigated. The study was divided into two lines, the first line was the experimental study involves the molding four reinforced concrete flat slab models with dimensions (1600×1600×100 mm) with three different dimensions of column capital (400×400 mm, 600×600 mm, and 800×800 mm) in addition to reference model without columns capital (column dimension 200×200 mm). The second line that numerical modeling through the ABAQUS finite element program was introduced. Effect of column’s capital size and shape of column’s capital (rectangular and circular) were studied experimentally and numerically. A good agreement was obtained between the experimental and theoretical study. The main conclusion that the punching shear strength of reinforced concrete flat slab was affected on the size and shape of a column capital.

To improve the bearing failure behavior of the exterior steel beam-reinforced concrete column joints composed of reinforced concrete columns, joint details using steel column was proposed. Steel column was attached to the lower flanges at right angles to the steel flange. The objective of this study is to clarify the effectiveness of proposed joint details experimentally and theoretically. To clarify the influence of steel column on the bearing failure of the joint, seven T-shaped subassemblages were tested under reversed cyclic loading. All specimens had the same cross sections of the steel beam. The experimental variables were the embedded length of the steel column, whether there is the end plate at the tip of the embedded steel column, and, the arrangement of transverse reinforcement ratio surrounding the steel column. The following remarks can be drawn from the test results. 1) In case of the specimen with a short embedded length of the steel column, the punching shear failure on the upper surface of the steel beam flange was remarkable when the maximum strength was reached. However, in the specimen with long embedded length of steel column, it was not observed the punching shear failure. 2) The maximum strength increased with the embedded length of the steel column. Further, the maximum strength of the specimen with the embedded length of three times of the steel column depths is subjected to bending yield strength of the steel column. 3) It was shown that the transverse reinforcement to surround the steel column and the end plate were necessary to improve the bearing failure of the joint.
