THE EXPERIMENT STUDY ON NEW CONSTRUCTION OF CONNECTION BETWEEN CONCRETE BEAMS WITH STEEL RECTANGULAR TUBE COLUMN FILLED IN CONCRETE

摘要

A new type of connection between rectangular concrete-filled tubular column and reinforced concrete beam was proposed. One specimen with 1: 3 scale of modeling for the practical project has been tested. The test setup of X-shape has been adopted to realize the cyclic load. The experimental phenomena and the strain distribution on different parts of specimen were obtained from the test. Additionally, hysteretic curve of joint between column and beam under cyclic loads was plotted and anti-seismic performance of joint has been discussed. The preliminary experimental results indicate that this kind of joint has reliable performance and it is simple to be constructed.
