Analysis of Beam-Column Joint in a Prestressed Concrete Structure under Reverse Cyclic Loading

The beam column joint in pre-stressed concrete member undergoes direct compression as well as bending compression and tension. This makes it vulnerable to failure. Concrete filled steel tubular structure is widely used in high-rise building. Generally, concrete filled steel tubular structure use the concrete inside and the steel tube wrapped around. This type of structure has some merits. Because of the complexity of the structure of joints, it can hardly be used consistent with prestressed concrete beam to form prestressed frame structure. This article use composite concrete column with core of concrete filled steel tube, put forward the structure form which is made up of prestressed concrete beam and composite concrete column with core of concrete filled steel tube. This paper includes the analysis of prestressed beam column joint with different tendon pattern also including the CFST column.
