Novel energy-consumption shock-absorbing filling wall board used for frame structure

Abstract

The invention belongs to the technical filed of building material, and in particular relates to a novel energy consumption and vibration reduction infilled wall board for a frame structure, wherein both sides of a ribbed composite wall board are connected with frame columns; flexible filling materials are arranged between the ribbed composite wall board and the frame columns; the top of the ribbed composite wall board is connected with frame beams through one or more than one slipping device; and the ribbed composite wall board is manufactured by taking a concrete sash as a framework and embedding gas-filling silicate building blocks which take furnace residue and fly ash as main raw materials. The novel energy consumption and vibration reduction infilled wall board for the frame structure has the advantages that the wall board does not participate in earthquake resistance under the condition of small earthquake, so that adverse effects of an infilled wall on the dynamic property and the anti-earthquake performance of the frame structure are avoided; the energy consumption and vibration reduction function of a ribbed composite wall is given full play under the condition of medium earthquake and large earthquake, and the anti-earthquake defense line and the safety margin of the frame structure under the condition of large earthquake are increased; and replacement of the whole wall body or local damaged building blocks can be performed according to the damage conditions after earthquake, so that the repair cost is low and the construction speed is quick.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a novel energy-dissipating and shock-absorbing filling wallboard for frame structures. Background technique [0002] Frame structure is one of the structural forms widely used in multi-story building buildings. Masonry infill walls and partition walls are usually used as non-structural force-bearing components, which mainly play the role of maintaining and separating spaces. The seismic damage investigations of buildings in recent years have shown that the interaction between the rigidly connected infill wall and the frame has an objective impact on the overall seismic performance of the structure that cannot be ignored. The adverse effects are mainly manifested as: (1) The vertical discontinuity of the infill wall leads to a sudden change in the stiffness of the storey to form a weak floor; (2) The non-uniform arrangement of the infill wall on the plane causes the cen...

Problems solved by technology

The adverse effects are mainly manifested as: (1) The vertical discontinuity of the infill wall leads to a sudden change in the stiffness of the storey to form a weak floor; (2) The non-uniform arrangement of the infill wall on the plane causes the center of rigidity and the center of gravity of the structure to not coincide, resulting in a small earthquake. Composite mechanical failure of frame columns occurs under the participation of torsion, such as the failure performance of the frame brick-concrete structure at the bottom of the commercial ground floor facing the street in an earthquake; The distribution of force among the frames does not consider the influence of ...
