Abstract:
The hysteretic behavior of Y-eccentrically braced frame with high strength steel combination (Y-HSS-EBF) which has shear link was studied according to the test of Y-HSS-EBF specimens under the cyclic loads. The restoring force model of Y-HSS-EBF is established based on the experimental results and theoretical analyses. A two-linear skeleton curve model with stiffness degradation which was defined through yield point and ultimate point was proposed. The formula for calculating the points are recommended through theoretical analyses. The results indicate that the calculated restoring force model is sufficient to agree with the experimental results, which can be applied to estimate the seismic performance and non-linear analysis of Y-HSS-EBF with shear link.
