Hysteretic Performance of Precast Beam-Column Joint with Improved Energy Dissipation Capacity
The structural elements are factory-made and transported to the site and connected using different mechanisms in precast concrete framed structure construction. The improved quality control reduced the construction period and the use of alternative construction materials made the precast construction more effective than the cast-in-situ construction. The connection between the structural elements such as beam to column, column to column, column to the foundation, beam to beam, slab to the beam plays a crucial role in deciding the performance of precast construction. The reconnaissance survey of many earthquakes shows the susceptibility of these structures under seismic force and shows the importance of connections in seismic resistance. Also, the various structural failures due to man-made mistakes exhibit the importance of proper design, execution with better workmanship. The connections can be categorized into three types such as dry, wet, and hybrid connections and the performances are distinct and vary concerning the materials used and methodology adopted. This article presents an overview of various precast structural connection systems and their hysteresis behavior. Also, an experimental program is conducted to study the cyclic behavior of indigenous precast beam-column connections with better seismic resistance. Precast column and beams were cast separately and connected using the proposed mechanism and tested under quasi-static loading. The hysteresis behavior and energy dissipation capacity are the parameters used to quantify the performance of the connections. The experimental behavior is compared with the performance of various connections proposed and observed that the proposed connection effectively works in resisting the seismic force with better damping capacity. Also, the failure pattern shows that the formation of plastic hinges away from the joint leads to ductile failure.
