Abstract

The purpose of this research is to study and analyze the seismic behavior of a full-scale interior slab-column connection specimen. The post-tensioned flat slab was installed by 8 bonded tendons, which pre-compressionequals to 2.3 MPa, and shear reinforcements, i.e., stud rails to protect punching shear, were placed in an orthogonal layout according to ACI 318.. The specimen was tested under cyclic lateral loading by displacement-controlled method until failure. The test results were presented in terms of relationship between lateral load and lateral drift ratio as hysteretic loop behavior. It was found that the specimen can resist the punching shear, and showed a lateral drift ratio about 7.5% at ultimate load. The specimen with the stud rails can improve ductility substantially.
