Supporting structure with damper independently adjusting rigidity and bearing capacity and design method thereof

Abstract

The invention relates to a supporting structure with a damper independently adjusting the rigidity and the bearing capacity and a design method thereof. The supporting structure comprises a supportingsection, a damper section and a connecting end plate for being connected with the supporting section and the damper section, wherein the damper section is assembled by a plurality of connected damping plates side by side, and the damping plates are manually buckled. Compared with the prior art, the coupling aim of the traditional supporting rigidity and bearing capacity is achieved, and the aimsof controlling the yield timing sequence and achieving damage control design in the structure are achieved; modularized joint design is adopted, and a supporting system with the large rigidity-and-bearing-capacity variation range can be assembled through the damping plates with few types; the damper section is connected with the supporting section in series, yield / buckling damage of common rigidity supporting connected with the damper section can be avoided, construction and replacement are convenient, the applicability is wide, and the effect is good.

Description

technical field [0001] The invention belongs to the technical field of energy dissipation and shock absorption of building structures, and in particular relates to a support structure with independently adjustable stiffness and bearing capacity dampers and a design method thereof. Background technique [0002] At present, the idea of ​​earthquake-resistant design of structures has shifted from preventing them from collapsing to being able to quickly repair them after a disaster to ensure that their original functions are not affected. Whether a structure can be repaired after an earthquake is very important to the feasibility of dismantling and reinstalling the damaged parts. The structural design puts forward two requirements: first, the structural damage position can be effectively controlled to the place that is easy to replace; second, the residual displacement of the structure after the earthquake is reduced, and factors such as uneven bolt holes affect the replacement. ...

AI Technical Summary

Problems solved by technology

Generally speaking, since the stiffness and bearing capacity of the support are coupled together, that is, members with higher stiffness will bear more force, but often such members have larger yield bearing capacity, so the timing of yielding is difficult to control

Of course, different steels can be used for regulation, but the yield bearing capacity of different grades of steels varies greatly and the types are limited, so the realization of the above functions in the structure will be limited
