A timber frame-energy-dissipating brace anti-lateral force structural system

Abstract

The invention relates to a wood framework or bamboo framework-energy consumption supporting lateral force-resisting structure system, which can be used for a multilayer bamboo-wood framework structure. The structure system is combined mainly by a wood (bamboo) beam, a wood (bamboo) post, beam-post nodes, a frictional damper, a wood (bamboo) support and post footing nodes, wherein the wood (bamboo) beam and the wood (bamboo) post are connected through bolts; and the frictional damper is positioned between the wood (bamboo) support and the wood (bamboo) beam and between the wood (bamboo) support and the wood (bamboo) post and is in bolt-connection between the wood (bamboo) support and the wood (bamboo) beam and between the wood (bamboo) support and the wood (bamboo) post. In small vibration, the frictional damper does not slide, the lateral force-resisting rigidity of the bamboo-wood framework can be effectively improved through the wood (bamboo) support, the overall lateral sway and deformation of the structure are small; in intermediate vibration or large vibration, the stressed shear applied to the frictional damper is greater than the sliding friction, the frictional surface in the damper begins sliding and consuming energy, the wood (bamboo) support rotates relative to the framework beam and the framework post at the damper, and through the mechanism, the structure damage at the framework beams, the framework post and the beam-post nodes can be greatly decreased. Once the wood (bamboo) support is damaged after vibration, the change is more convenient, and the maintenance cost and the repair difficulty of the structure after vibration can be reduced.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a wooden frame-energy-dissipating support anti-lateral force structural system, which has low damage after an earthquake and can be used in a multi-layer bamboo-wood frame structure. Background technique [0002] With the increasing emphasis on environmental protection, the construction industry is increasingly advocating the use of renewable building materials. Wood and bamboo are increasingly used in house construction due to their natural growth and sustainable development. At the same time, the bamboo and wood structure also has the advantages of low energy consumption throughout the life of the building, an excellent living environment and architectural beauty. [0003] The scale of modern cities continues to increase and the requirements for land conservation continue to increase. The research and development of bamboo and wood structure systems suitable for multi-s...

Problems solved by technology

[0005] Aiming at the problem that the existing bamboo-wood frame structure is difficult to balance the anti-lateral stiffness and anti-seismic performance under earthquake action, the purpose of the present invention is to provide a wooden frame-energy-dissipating brace anti-lateral force structural system, through rationally setting The support can not only effectively increase the lateral stiffness of the structure under small earthquakes, but also use the sliding of the damper to drive the relative deformation of the support, effectively improve the energy dissipation performance of the structure under large earthquakes, and at the same time reduce the stress at the connection between the support and the structure. The degree of damage has greatly reduced the cost and difficulty of repairing the bamboo-wood frame structure after the earthquake
