Strength and Rigidity of Joints in Large Panel Buildings

The results of experimental research concerning the strength and stiffness of joints of large panel buildings are introduced in this paper. In it, pure shear strength of concrete, adhesive shear strength of joint material, effect of shear span ratio on shear strength,relationship between axial compressive stress and shearing resistance, shearing resistance due to shear-friction, shear strength and deformation behavior of vertical joints, shear strength and stiffness of horizontal joints in consideration of several factors, selection of the types and shear strength of the joints of connecting beams, compressive strength and stiffness of horizontal joints etc. have been studied.These results can be used as a reference for improving the design of large panel buildings in earthquake zones and for revision of the design code of large panel buildings.
