Experiment on Working Performance of Connection Constructional Measure Between Concrete Filled Steel Tube Columns and Shear Wall

Shear wall with concrete filled steel tube columns is a new kind of shear wall, which can fully display the advantages of the big lateral stiffness of concrete shear wall and good seismic behavior of concrete filled steel tube column.In order to bring the advantages into full play and guarantee seismic safety, it is important to design a reasonable shear connection between constructional measures.For studying working performance of connection of constructional measures, experiments of 6 joint models with different connection constructional measures have been done by applying low frequency circle load.The load-carrying capacity, energy dissipation, hysteretic properties and the failure features of each moedl are contrastively analyzed.The experiment indicates that safe connection between concrete filled steel tube column and concrete shear wall can be assured by adopting reasonable connection of constructional measures.
