Study on Seismic Behavior of Double Web-Angle and Top-Seat-Angle Beam-to-Column Connections

Article Preview

Abstract:

In order to study seismic behavior of double web-angle and top-seat-Angle connections, finite element methods, which included material, geometric and contact nonlinearity, were used to the model under cyclic loading. The effects of the angle length, the angle thickness, the bolt diameter and grade on strength, and the gauge distance from the edge of the angle to the center of bolt line on strength and hysteretic behavior of connections were studied. Finite element results reveal that the hysteretic behavior, initial stiffness and load bearing capacity are significantly affected by the gauge distance from the edge of the angle to the center of bolt line, the angle length, the angle thickness and the bolt diameter and grade.
