Based on experimental research of four joints of prestressed concrete beam and
composite concrete column with core of concrete filled steel tube and one joint of
ordinary prestressed frame structure, the ductility, energy dissipation, hysteresis
property and the mechanical behavior of joints have been analyzed. It also takes
researches on reliability of the design method and the influence of factor.
Experimental results indicate that this kind of joints can raise the shear strength of
core area of joints and its seismic performance is also good, this design method can
resolve the problem of the traditional concrete filled steel tubular structure effectively,
and can also meet the requirement of the high-rise and large span structure. It can be
useful reference to engineering design.
