Nonlinear analysis of the gusset plate connection for braced frames subjected to monotonic and cyclic loading

Abstract EN

In this paper, studies on braced frames are presented to study their behavior under the influence of seismic loads.

steel braced frame systems are considered an efficient and economical technique to resist horizontal and to maintain the lateral deformation of buildings under the effect of wind and seismic loads.

among these studies, a study was conducted at the university of California-Berkeley, America, in 2012-2013 by Lai and Mahin.

this study conducted laboratory tests for three full-scale one-bay two-story braced frames with different cross sections for the braces such as square-HSS, circular-HSS and wide-flange I beam.

a three-dimensional model is conducted to validate the laboratory test, using Abaqus program.

in this model, non-linear material properties are used for each part of the model.

two types of loading are developed, nonlinear static and nonlinear dynamic.

a comparison is made between the results of the experimental test and the numerical model, which showed that good agreement between these results.
