Masonry structure-based isolated structure

Abstract

The invention provides a masonry structure-based isolated structure, which comprises a building blocks layer and an isolated layer in vertical alternating arrangement, wherein the building block layer comprises an upper reinforcement mortar layer, building blocks, and a lower reinforcement mortar layer; and the isolated layer is located between the adjacent two building block layers. The whole isolated structure is arranged between a foundation top surface and the superstructure, thus, the structure can bear most of deformation of the whole building under the action of earthquake so as to ensure safety and reliability of the superstructure. The building block layer only generates horizontal rigid motion at the time of suffering the earthquake; and the isolated layer arranged between a foundation top surface and the superstructure generates horizontal shearing deformation, which restrains the horizontal motion of the building block layer, thereby having isolating function and limit effect. The invention has the advantages of reasonable structure, simple construction and lower cost of construction, can effectively improve shock absorption and disaster prevention capacity of brickworking houses, obviously improves the isolated capacity of the brickworking houses based on the non-change traditional construction method and particularly is applied by being matched with brickworking buildings.

Description

technical field [0001] The invention discloses a shock-isolation structure, in particular to a shock-isolation structure based on a masonry building; it belongs to the technical field of building structures. Background technique [0002] In recent years, several major earthquakes in my country have occurred in rural areas or towns. Most of the houses in these areas are masonry buildings, which suffered a lot of damage in the earthquake. The lateral stiffness of masonry buildings is usually relatively large, and its basic period T is generally smaller than the characteristic period Tg of the site. Therefore, the earthquake loads that this kind of houses bear in earthquakes are often very large, such as figure 2 shown. Since the strength of masonry structures is generally low, structural damage is inevitable if necessary construction measures are not added. If these measures are increased, the cost of housing will inevitably be increased. Although our country already has m...

Problems solved by technology

Although our country already has many seismic isolation measures, these measures are either too expensive, or have complex structures and high technical requirements.
