A fuse type frame infill wall panel and its design method

Abstract

The patent of the present invention relates to a fuse-type frame filled wallboard and its design method, which includes: frame beams, frame columns, filled walls, upper fuses, side fuses, flexible filling materials, elastic materials and their connectors, wherein the frame beams, Horizontal gaps and vertical gaps are respectively set between the frame columns and the filling walls, and are filled with flexible filling materials; the frame beams and frame columns are respectively connected to the filling walls through upper fuses and side fuses. Frame beams, frame columns and infill walls can be designed in advance according to current codes, and then horizontal gaps, vertical gaps, upper fuses, side fuses and corresponding connections should be designed. Through the setting of the fuse, the coordinated work between the various components is realized. The design is reasonable and the force transmission is clear. It can not only effectively eliminate the stiffness effect and restraint effect of the filling wall on the frame, but also make it the last line of defense against the collapse of the house; Changing the design and construction methods of traditional frames, the design is simple, easy to construct and maintain, thereby reducing costs.

Description

technical field [0001] The invention belongs to the field of anti-seismic technology of structural engineering, and relates to a wall panel filled with a fuse type frame and a design method. Background technique [0002] Infill wall is an indispensable element in the frame structure system, which usually plays the role of enclosure and separation, and its role is usually not considered in the design. Since the presence of infill walls increases the stiffness and strength of frame structures, most researchers and designers are optimistic that the presence of infill walls improves the seismic performance of frame structures. However, a large number of earthquake damage shows that a large number of frame houses collapsed due to the action of the infill wall. The reason is mainly due to the stiffness effect and restraint effect of the infill wall. The structure was severely damaged or even collapsed, causing a large number of casualties and property losses. [0003] At present...

Problems solved by technology

The first solution, because the energy-dissipating materials are added to the infill wall, effectively improves the strength and energy dissipation capacity of the entire frame system, but the current solution still requires the infill wall and the frame to resist external loads, and the infill wall cannot be avoided. The rigidity effect and restraint effect, and the cost of the whole system is increased due to the input of energy-consuming materials

The second option is to set flexible filling materials between the filling wall and the frame beams and columns to form a flexible partition, which eliminates the stiffness effect and restraint effect of the filling wall on the frame. However, the flexible partition greatly weakens the effect of the frame on the filling wall panel. On the one hand, it increases the risk of out-of-plane collapse of the infill wall panels; on the other hand, it does not give full play to the resistance of the infill wall in the structural system, which is a waste in disguise
