Fuse-type frame filling wall plate and design method thereof

Abstract

The invention relates to a fuse-type frame filling wall plate and a design method. The fuse-type frame filling wall plate comprises frame beams, frame columns, a filling wall, upper fuses, side fuses,flexible filling materials, elastic materials, and connecting pieces thereof. Horizontal clearances and vertical clearances are arranged between the frame beams and the filling wall as well as between the frame columns and the filling wall correspondingly and filled with the flexible filling materials correspondingly. The frame beams and the frame columns are connected with the filling wall through the upper fuses and the side fuses correspondingly. The frame beams, the frame columns and the filling wall can be designed in advance according to the current specification, and then the horizontal clearances, the vertical clearances, the upper fuses, the side fuses and corresponding connection are designed. By arranging the fuses, coordination work between all components is achieved, the design is reasonable, force transmission is clear, the stiffness effect and restrain effect of the filling wall on a frame can be effectively eliminated, and the filling wall is also made to become the last defense line against house collapse; and the design and construction modes of a traditional frame are basically not changed, the design is simple, construction and maintenance are easy, and thus the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of structural engineering anti-seismic, and relates to a method for filling wall panels with a fuse-type frame and a design method. Background technique [0002] The 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 the frame structure, most researchers and designers are optimistic that the presence of infill walls improves the seismic performance of the frame structure. However, a large number of earthquake damages show 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, which makes the infill wall structure suffer from weak layer damage and torsional damage under the action of the e...

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
