Prestressed Energy Dissipating Cable Bracing Device and Its Calculation Method

Abstract

The invention provides a prestressing force energy-dissipating and cable-supporting device and a calculating method thereof. The prestressing force energy-dissipating and cable-supporting device comprises a first cover plate, a second cover plate, a metal energy-dissipating device, a first cable-supporting system and a second cable-supporting system, wherein the metal energy-dissipating device is positioned between the first cover plate and the second cover plate; the first cable-supporting system consists of four first inhaul cables; each two first inhaul cables are respectively arranged on two sides of the first cover plate in an intersected mode and are connected with the first cover plate; the second cable-supporting system consists of four second inhaul cables; and the four second inhaul cables are arranged in a divergence mode and are connected with the second cover plate. The metal energy-dissipating device is used on the basis of cable supporting, the shortcoming that a hysteretic curve of the cable-supporting systems is not full is overcome, and by an applied prestressing force, the cable-supporting systems can be always in a tensioned state when the structure deforms, and instability is avoided.

Description

technical field [0001] The invention relates to a prestressed energy dissipation cable bracing device and a calculation method thereof, belonging to the field of construction. Background technique [0002] The anti-lateral force member of the structure is an important component of the structure, which bears the important role of resisting wind load and earthquake action. The idea of ​​energy dissipation and shock absorption is a technical method that has gradually been valued in my country in the past two decades. The core of this idea is to install energy dissipation devices in the structure to dissipate the energy input to the structure by external actions, so as to protect the main structure and reduce the energy consumption. Minor structural damage. Energy dissipation and shock absorbing devices can be divided into viscous damper devices, metal hysteretic energy dissipation devices, frictional energy dissipation devices, viscoelastic energy dissipation devices, etc. acco...
