Analysis study of extended end plate connection due to cyclic load using finite element method

Abstract

In steel frame structures, the connection is very important element to design, especially for earthquake resistant structures. How to choose the material and and dimension are very important things in steel connection to receive the load. Nowadays, the application of joints using extended end-plate has become popular because of it easy fabrication, the erection, and precise seismic performance. This connection is used to connect beam to column or connect the two beams. As a study material, we’ll make the detail of steel connection due to cyclic load using Abaqus 2017. In this research, we will remodel the connection from previous research with a end-plate modification using finite element method. The dimension of beam is I - 360 × 170 × 12 × 8 and the column is I - 213 × 222 × 10 × 7 with the thickness of end plate is 15 mm and using Grade 8.8 bolts. There are 3 types variation model, one for verification of previous research, and the other two were modified connections. The result of the study is Extended End-Plate can affect the value of the displacement. Connection using Extended End-Plate has smaller displacements, so its better to receive the loads that can cause the collapse. Extended End-Plate also affects the value of lateral load that can be borne. Connection using Extended End-Plate can receive the greater lateral loads, so its more stable and stronger to holding the loads. From the three specimens analyzed, the first model has the best performance where there are extended end plates on both sides.
