This paper provides test results of punching shear-reinforced slab-column connections formed by prefabricated vertical steel sheets, developed to optimize the construction process. To evaluate the punching performance of this novel punching shear key, one slab without shear reinforcement and six slab-colu...
reinforcement can increase not only the punching shear ultimate capacity but also deformation of the member;the location and effective pre-stress of the reinforcements have great influence on bearing capacity and deformation of the connection.A new formula of calculating the ultimate punching shear ...
Strain-based strength model for direct punching shear of interior slab–column connections A strength model was developed to predict the direct punching shear strength of interior slab–column connections without shear reinforcement. At slab–col... HG Park,KK Choi,C Lan - 《Engineering Structures》...
The design of a flat plate structure is generally governed either by serviceability limits on deflection or punching shear strength of the column slab connections. To increase the strength of a column slab connection, a new type of shear reinforcement, referred to as shear stud, is gaining ...
The overall aim of this paper is to develop a unified design method for the punching shear resistance of slab-column connections irrespective of the type of internal reinforcement. In the first part of the paper a design model for the punching shear resistance of concrete slab-column connections...
The improvement in the proposed method is due to the incorporation of slab depth factors for both the flexural and shear modes of punching failure and refinements to the effects of concrete strength, reinforcement percentage and reinforcement yield strength, for the shear mode of punching failure. ...
