Combination Of High Strength Steel Single Layer Single Span K-EBF Mechanical Performance Test

The combination of high strength steel K-EBF，whose link is low strength steel, therest of the member is higher strength steel. It combines a high load carrying capacity ofhigh-strength steel and good seismic performance advantages of EBF, who is a highlyseismic steel structure system and the intersection and fusion of these two researchareas.The combination of high strength steel EBF system is the use of the linkenergy-consuming when the link entered into the plastic, the other components in theelastic stage.In order to study the seismic performance of the structural system, the papermainly accomplish the following work：(1)On the basis of the existing high-strength steel and EBF research, consideringthe length of the link seismic performance, design the shear yield type and bendingyield type1/2reduction specimen. Two specimens were monotonic loading and lowcyclic loading tests;(2) According to the experimental phenomena and the data collected on the testresults for analysis. Drawn the bearing capacity, lateral stiffness and yield displacementin monotonic load of the specimen；drawn hysteresis curves, skeleton curves, stiffnessdegradation, ductility factor in low cyclic loading of specimen;(3)Comparing the seismic impact factors of shear yield type and bending yield typespecimen;(4) Failure modes and the eccentrically braced steel frames destroyed force of the various components of two specimens under cyclic loading are gave by strain analysis;(5)Give the suggestion of K-EBF repair recommendations after the earthquake.
