Abstract - A bolted connection is presented with splicing
plates to facilitate assembly and increases the tightness of the joints. The joints have three modules and are arranged using bolts on the site. Cyclic experiments and finite element analysis (FEA) are performed on the mode by using Ansys software. The study reported here has experimentally evaluated a variety of unstable types of bolt assemblies for seismic applications. This connection includes a modified bolt assembly that is designed to promote a uniform distribution of forces in the bolt group. The study reported here describes the results of a full-scale test of different types of bolts using the Ansys workbench. In experimental development, the details of the test results will be suppressed and the connection performance will be checked through the Ansys workbench. Bolt extended end plate connections have shown that they can provide a considerable amount of flexibility and waste energy. These connections are pre-qualified for use in special and intermediate moment frames widely due to their superior flexibility in multi-story buildings and their ability to cause loss of energy during strong ground energy dissipation.
Fig -1: Extended end plate connection Connection bonding is the main position of the beam and column, the hinge of the force transferred in the frame, and its performance directly affects the safety of the entire steel frame. A typical connection used in the steel moment frame is a fully welded connection, the full joint penetration conduit welds connect the beam flange to the column flange, and the fillet welds connect the beam web to the column flange, as shown in Figure 2.

1. INTRODUCTION The end-plate connection is composed of a steel plate welded at the end of a beam section, welded with an adjacent member using rows of high-capacity bolts of full pressure. The connection can consist of two beams (splice plate connections) or a beam and a column. The end-plate moment connection is classified as flushed or extended, with or without a stiffener, and further based on the number of bolts in the stress flange.
Fig -2: Connection details Bolt extended end plate connections overcome the problems associated with field welding, speeding them to be installed during frame construction, and are more suitable for winter construction than field welded connections.
