Abstract

The type of end-plate connection is mostly used in the steel structure connection which carries the moment. The connection can be an end-plate welded to the beam and connected to the column with bolts. The end-plate can be assembled without extended plate (flush-plate) or with extended end plate. Besides that, the steel-connection which carries the moment can also be assembled with the flangeplate connection where the plates is connected with bolts to the beam and welded to the column. The experiment of the steel wide flange beam-column using end-plate has a better ability to resist the loads than flange-plate connection. It can be seen from the maximum limit load of end-plate connectiont is bigger than flange-plate connection for the finite element method or the experiment. The maximum limit load of the connection using the end-plate is 1.087 times bigger than the connection using the flange plate based on the finite element method and the result reaches to 1.105 times bigger based on the experiment. The maximum-limit load of connection using the end-plate is 51.8% from the finite element method and reaches to 58.0% from the experiment compared with the rigid connection. However, for the flange-plate connection is 4 7. 6% from the finite element method and reaches to 5 2. 4% from the experiment compared with the rigid connection. The difference of maximum-limit load of the end-plate connection from the experiment and the finite element method reaches to 10. 6%, while for flange-plate connection the difference is 9.18%. The connection design capacity based on AISCLRFD 2010 is 3, 7 40 kilograms for the end-plate connection and 3,180 kilograms for the flange-plate connection.
