Abstract

Braces are used as effective seismic elements in seismic regions. They are widely used in low to high-rise buildings. However under an earthquake loading, Conventional braces are directed to the BUCKLING rapidly. Repeated BUCKLING and yielding of the braces cause a stiffuess and strength degradation which may reduce the overall frame stability. To solve the above problem, a number of studies have been introduced on the use of new Ductile brace using in CONCENTRICALLY BRACED FRAMEs (DCBF), in which BUCKLING has been restrained. This new brace is yielded in tension as well as in compression in which dissipate seismic energy in both direction of loading. This paper describes the main characteristics of the inelastic seismic response of the such Ductile Braces (DCB).In order to study the seismic behavior of the new developed DCBs with the new proposed cover and encasing material achieving a series of new effective and economical DCB, several large-scale braces have been tested. In this study, first the new four types of DCBs that have been developed at BEES are introduced, designed and tested, and then the hysteretic characteristics and energy dissipation of the DCBs under cyclic loading are investigated.
