Effects of Beam Eccentricity on Behavior of Connections between Hollow Section Steel Beam to Concrete Infilled Column

Abstract

There are number of factors that influence to behavior of beam-to-column connections. According previous studies, beam eccentricity is an importance factor which affects to the connection’s behavior, especially for the connections that the beam width is less than the column width. The initial stiffness and moment capacity are increased when the beam eccentricity increased. Therefore, this paper aims to study about effects of the beam eccentricity on behavior of hollow section steel beam-to-concrete infilled column connections. The cantilever tests are performed to evaluate the behavior of the connections. Results show that initial stiffness of the connection with infilled concrete is increased about 1.72 time while moment capacity of the connection with infilled concrete is increased about 2.62 time compared to those without concrete.
