Abstract

Based on 3 specimens of hybrid reinforced beam transfer structure and 1 specimen of reinforced concrete beam transfer structure for pseudo static test. With comparison and analysis of reinforced concrete beam transfer structure, flexural performance, yielding mechanism, failure mechanism, and bearing capacity, hysteretic behavior, stiffness degradation, ductility and seismic performance of hybrid reinforced beam transfer structure under vertical load and horizontal loads were studied, the CFRP anchor at the end was measured. The test results show that: bearing capacity of hybrid reinforcement beam transfer structure is better than that of reinforced concrete beam transfer structure; structural ductility coefficient is greater than 3, stiffness degradation curves were not downhill, skeleton curve decreased slowly, and the hysteresis curve is plump; hybrid reinforced beam transfer structure is with good ductility and seismic performance; The structure meets China seismic code requirements for design of ductile frames " strong column, weak beam, strong nodes ". If the anchorage is safe , CFRP bars, concrete and steel can jointly work reliably.
