ABSTRACT:

The connections of pre-fabricated steel structures have become a major issue in recent decades due to the need for rapid constructions. In the past years, several studies have been conducted with the aim of developing simple and efficient connections. Here, a new modularized pre-fabricated steel moment connection is proposed, which is composed of a short column with a pyramid head for a fast and easy assembling. In this paper, the behavior of this connection is investigated through using several cross-section shapes and plates with different thickness. The obtained force–displacement and moment–rotation curves of the connection under cyclic loads indicate that a 20 percent increase in the thickness of the beam and column connection plates raises the yielding moment, yielding rotation and the maximum rotation capacity of the connection by 21, 19 and 13 percent respectively. The results also suggest that the proposed model has a higher capacity as well as reliable performance comparing to other moment connections.
