Embodiment Construction

[0013] In order to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] like Figure 1-Figure 3 As shown, the building structure deformation coordination control system based on chain hydraulic transmission includes a plurality of oil dampers 14 in series, and the plurality of oil dampers are respectively installed corresponding to each floor, and the piston rod and the outer sleeve of a single oil damper The two oil dampers on the two floors are connected through the casing 12. The casing is composed of two intersecting connecting pipes, and the two ends of each connecting pipe are respectively connected. The inlet and outlet of the oil cylinders of the two oil dampers make the two oil cylinders communicate in reverse, the oil cylinders are filled with hydraulic oil 13, fluid exchange can occur between the two oil cylinders when deformed, and the hydraulic oil in ...

Abstract

The invention provides a building structure deformation coordination control system based on chain type hydraulic conduction. The building structure deformation coordination control system is characterized in that two oil cylinders are arranged in a single oil damper, two pistons are correspondingly arranged, inlets and outlets are respectively formed in both sides of the pistons in the oil cylinders, the two oil cylinders of two adjacent oil dampers reversely communicate with each other through sleeves, the whole system is formed by connecting in series, and an inlet and an outlet of one oil cylinder of each of the head floor and the tail floor communicate with each other through a self-circulation pipe or a sleeve so as to form a closed-loop system. The building structure deformation coordination control system has the advantage of the clever structure, has the effects of controlling the structure deformation amplitude and controlling the deformation consistency, can prevent deformation from being concentrated on weak parts of a building structure and has an excellent control effect.

Description

technical field [0001] The invention belongs to the technical field of vibration control of civil engineering structures, and in particular relates to a coordinated control system for building structure deformation based on chain hydraulic transmission. Background technique [0002] Civil engineering structures produce reciprocating vibrations under the action of external environmental dynamic loads, and excessive deformation will affect the safety performance, performance and durability of the structure. Based on structural control technology, energy dissipation dampers are installed in the structural system to control the dynamic response of the structure within the allowable range by dissipating the structural vibration energy, so as to achieve the purpose of controlling structural vibration and improving structural performance. Passive control technology has the advantages of stable performance and low maintenance cost. However, due to the huge uncertainty of the extern...
