Experimental Investigation of Precast Horizontal Wall Panel Connection using Reinforcement by Push Off Test

The precast concrete shear wall system is very important for construction due to economic advantages in the speed of construction. The connections between panels are extremely important since they affect both the speed of the erection and the overall integrity of the structure. This project deals with the experimental study of shear transfer in precast concrete wall panels using dowel action and shear friction concept. The horizontal connection of the wall panels is considered in this project. This project is completely done referring to Indian Standard Codes. This paper describes the analytical and experimental behavior of precast wall panel with the horizontal connection. Dimension of the panel is 500mm x 400mm x 100mm and M35 grade of concrete has to be used. The primary purpose of this project is to derive an equation relating the transfer of loads through shear friction action to dowel action, to obtain a connection to resist both gravity loads and lateral shear and to validate the wall panel connection using dowel bar by conducting push off test. The dowel bar is provided with a diameter of 12 mm is used to connect the two panels. The development length (Ld) of the bar is provided with varying in size as 300 mm, 400 mm, 600mm and the behavior of the connection is studied. Analytical study will be done using ABAQUS 6.12 software.
