With the development of economy,fasteners template scaffold are more and more widely used. Duing to the construction, defects, however,right-angle fastener of fasteners template scaffold can not meet the corresponding requirement specification ,which lead more and more safety accidents. Right-angle namely called Semi-rigid nodesis between that of rigid connection and hingedconnection. Existing data show that the value of semi-rigid nodes have a certain influence on the ultimate bearing capacity.Using eigenvalue buckling analysis and numerical analysis methods, this paper explorefurther the relationship between semi-rigid nodes and ultimate bearing capacity. Studies have shown that the initial rotational stiffness has a very significant effect on bearing capacity when tightening torque is small ,and moreover,ultimate bearing capacity of the fasteners template scaffold increases non-linearly with the increase of semi-rigid.
