There is an increasing demand for precast reinforced concrete (RC) structures due to their undeniable advantages, such as rapid assembly, material standardization, and labor quality. The wedge detail tested in this project is a new design that builds upon the idea of inducing a plastic hinge away from the column face to dissipate the energy that would otherwise yield the connection. The Kaiser bolted bracket (KBB) is a new beam-to-column moment connection that consists of proprietary cast high-strength steel brackets that are fastened to the flanges of a beam and then bolted to Choose a type of moment-resisting connection (C1) that meets the design requirements.

The connection employs the concept of slip-friction, which has been successfully used in several steel structures and allows for energy dissipation though friction slip, hence realize a If it's a seismic-resisting moment connection, I use Omega. Moreover, moment-resisting connections in the seismic regions should have adequate ductility to dissipate large amounts of energy and prevent failure under strong earthquakes. , and Sabol, T. 1999!. com In particular, moment resisting beam-to-column connections in welded steel moment frames (WSMFs) were considered to be able to withstand large inelastic deformations without developing significant strength degradation or instabilities and that should damage. This solution takes advantage of long threaded rods' high axial stiffness and resistance and the lack of initial slip [[30], [31], [32], [33]]. With conventional welded and bolted joints’ response being generally very flexible, the design resistance becomes governed by a deformation criterion rather than a strength criterion. Introduction Extensive failure in welded unreinforced flange (WUF) connections in steel moment resisting frames (MRFs) during the 1994 Northridge Earthquake highlighted the poor seismic performance of these connections [1]. 1 Concentric Connections BOLTED CONNECTIONS – I Version II 33 - 3 (b) Classification based on the type of force experienced by the bolts: The bolted connections can also be Moment-rotation curves and failure shapes are derived to discuss the cyclic behaviour of the connection with respect to the conventional connection configuration.
