One of the significant differences between steel and concrete materials is that the steel shear plasticity has a stable energy consumption. In-depth research also shows that even if the plate is partially destabilized, the plastic energy consumption caused by the bending deformation is very considerable. The active use of this property in the design will effectively improve the structural efficiency, and the wall structure can be used to improve the rigidity of the structural system. Carrying capacity.
It is a feasible structural scheme to install a number of light steel shear walls with certain anti-side stiffness and horizontal bearing capacity while effectively dissipating seismic input energy in the steel structure bending frame. Determine the stiffness requirements and parameter specifications of the stiffeners and upper and lower beam members of the shear wall, so as to ensure that the cross-section and structure of these edge members can be reasonably designed to ensure the stiffness, horizontal bearing capacity, stable energy consumption, etc. of the shear wall. The expected functionality can be achieved.
The reason why the shear connection between the shear wall and the upper and lower beams is slipped under the reciprocating horizontal load is that the additional shear force generated by the overturning moment and the severe non-uniformity of the bolt internal force caused by the shear lag are neglected, and the internal force calculation of the connecting bolt is proposed. Method and configuration method. It has been verified by experiments that the method can effectively avoid the slip and noise generated in the high-strength bolt-type connection before the relative deformation angle of the structure exceeds 2%, which provides a feasible solution for implementing the full bolt connection structure, thus ensuring the assembly construction. It ensures easy replacement after the earthquake is damaged.
