Study of the Hysteretic Capacity of the Steel-concrete Composite Beam to Concrete-filled Steel Tubular Column Joints
摘要
Abstract
In order to study the seismic performance of the steel-concrete composite beam to concrete-filled steel tubular column joints, this paper analyzed the hysteretic capacity of two experimental joints based on the experimental results and the simulation of the both joints under low cyclic loads. The author proposed the tri-linear restoring force model and the range of the feature component, and also the expression of the restoring force model. The result shows that the specimens have good seismic performance and the skeleton curve of the established restoring force model is similar to the experimental values. The skeleton curves and the hysteretic curves of the experiment and the FEA match well during the elastic stage. But the differences of them increase under the cyclic load.关键词
