Self-resetting laminated wooden structure beam-column joint capable of replacing frictional energy consuming devices

Abstract

The invention discloses a self-resetting laminated wooden structure beam-column joint capable of replacing frictional energy consuming devices. The self-resetting laminated wooden structure beam-column joint comprises a laminated wooden column, a laminated wooden beam and a frictional energy consuming device, wherein the laminated wooden beam is located on one side of the laminated wooden column,and the laminated wooden column and the laminated wooden beam are connected as a whole by the frictional energy consuming device. The frictional energy consuming device comprises two inner friction steel plates, an inner friction end plate, two outer friction steel plates and an outer friction connection steel plate. The inner friction steel plates reserved with first friction bolt holes and firstfixation bolt holes are fixed to the laminated wooden beam, the two inner friction steel plates are connected as a whole by the inner friction end plate, the two outer friction steel plates reservedwith third friction bolt holes and third fixation bolt holes are fixed to the laminated wooden column, and the two outer friction steel plates are connected as a whole by the outer friction connectionsteel plate. The self-resetting laminated wooden structure beam-column joint can consume energy of the action of an earthquake, and eliminate or reduce residual deformation of a prefabricated woodenstructure under the action of the earthquake.

Description

technical field [0001] The invention belongs to the field of civil engineering, and relates to a self-resetting glued wood structure beam-column joint with replaceable frictional energy dissipators. Background technique [0002] In recent years, in order to improve the efficiency of structural construction and improve the quality of buildings, the state has promulgated a series of documents to vigorously promote the industrialization of buildings. The document clearly pointed out that the development of prefabricated buildings is a major change in the construction method and an important measure to promote the structural reform of the supply side and the development of new urbanization. On the other hand, as a building form with a long history and advancing with the times, the wooden structure system has the advantages of flexible design, simple construction, fast construction, good wind and earthquake resistance, high comfort, beautiful structure, energy saving and environm...

Problems solved by technology

[0004] (1) The connection of prefabricated structural nodes has always been one of the hot issues discussed in the academic and engineering circles, and the application of prefabricated building structures is also limited to a certain extent, and the failure mode of prefabricated wooden structure nodes under earthquake action shows even more Large unpredictability. At the same time, the elastic modulus of wood is relatively low, resulting in large deformation. After the wood structure enters plasticity, the deformation is difficult to recover, and it is easy to form a large residual deformation

[0005] (2) The beam-column connection is the most critical design link in the prefabricated structural frame design. The existing connection forms mostly refer to the joint structure form of the steel frame, but the wood structure itself does not have the advantages of high strength of the steel structure, and the wood frame is commonly used The stiffness of beam-column joints is relatively small, and it is designed as hinged joints in structural design. Insufficient joint stiffness is a restrictive factor for wood frame joints. Setting a large number of supports will have a certain degree of impact on the aesthetics of the structure, which in turn makes the building performance unsatisfactory. fully use
