| Abstract: | A 1/3 scale model was constructed and subjected to a series of earthquake excitations to investigated the seismic behavior of the precast frame-core tube structures with reinforced concrete(RC) beams and concrete filled steel tubular(CFST) conlums.The seismic behavior of this type of structures,including the seismic response,the reliability of connections,and the failure mechanisms are studied in this paper.The test results have shown that: this type of structures has excellent bearing capacity and seismic behavior,and the connections could generally satisfy the requirement in the structural design codes. |
