Steel reinforced concrete (SRC) structure with special-shaped columns is the combination of SRC structure and special-shaped column structure, has high bearing capacity, good anti-seismic performance, avoid appear sharp edges around the house, has a broad application prospect. At present, the study of SRC special-shaped column structure is less, for SRC special-shaped column nodes research is in its infancy. Nodes as beam-column connection hub, its reliability is the premise to guarantee the normal work of the structure. Through 9 SRC frame T node low reversed cyclic loading experiment, the seismic performance of SRC frame T node is analyzed, and summarizes the concrete intensity, axial compression ratio, steel form, limb appendage thick than factors such as high bearing capacity and ductility of SRC frame T node, combined with the force mechanism of nodes, and puts forward the suitable for different steel form, different loading direction of SRC frame T node in the core crack, shear, torsion bearing capacity of practical calculation formula. Research results of this paper as the research framework SRC special-shaped column nodes work laid the foundation for the later research, and to establish the accurate node of SRC frame T crack, shear and torsion bearing capacity calculation formula, provides the reference for the popularization and application of SRC special-shaped column structure play a good role in promoting.
