Abstract

In structures with brace, one major problem is the great hardness of the bracings frames which are efficient to improve the seismic performance and to reduce the size of the hardness. A highly stiff braced frame cannot adequately dissipate the energy exerted by earthquake, so it causes the structure to absorb a large portion of this energy. As a result, designers always look for viable strategies that allow the steel structure to move along earthquake motions and dissipate this energy. This paper sought to evaluate one of such strategies, which is the use of rubber and lrad rings in the bolted connections between braces and gusset plates. Finite element software (Abaqus / 6.13) was used to perform a dynamics analysis on a frame by subjecting it to the seismic records of Bam, Kobe and San Fernando earthquakes. This procedure was then repeated for the frame whose bolted connections contain rubber and LEAD RINGS and the values of base shear, drift, maximum stress in the structural members and the internal energy of the structure were compared. The results showed that the adding RUBBER RINGS to the connections of braced frame decreases its maximum base shear and energy absorption.
