Abstract
Quasistatic experiments of concrete spatial frame joints are carried out under biaxial cyclic lateral loading. The torsional phenomenon of different joint types under biaxial cyclically increasing horizontal displacement loading is analyzed, and the shear mechanism is studied from the angle of stress based on finite element analysis. In this paper, the influence comparison on torsional phenomenon of different joint types are given, the further analysis shows that the response of torsional vibration is the main influence factor on shear capacity of core joints, and the results of this study can be used to provide suggestion for the design rules of joint core considering torsion effect.
