Rigid-flexible multi-defense line control method and control structure for collapse and collision of adjacent frame structures

Abstract

The invention discloses a rigid-flexible joint multi-defense-line control method and structure for collapse collision of adjacent frame structures. The rigid-flexible joint multi-defense-line controlmethod comprises the following steps: embedded parts are arranged on beam-column joints of the frame structures, and steel cables are laid in two adjacent frames of every two adjacent building frame structures in the vertical direction, wherein only the axes of the steel cables bear force; the steel cables and the embedded parts are connected; and horizontal soft steel dampers and viscous dampersare alternately arranged between the adjacent frame structures in the height direction. According to the multi-defense-line control structure obtained through the method, materials are easy to obtain,construction is easy and convenient, the advantages of components can be mutually complemented, replaceability is achieved, and engineering application is facilitated; and the vertical flexible steelcables and the horizontal rigid dampers laid between the adjacent frame structures are combined, thus part of energy of external force loads such as earthquakes can be dissipated, dynamic response ofthe structures is directly reduced, meanwhile, the collapse probability of the adjacent building structures under the effect of the earthquakes can be decreased, and the disaster prevention and reduction capacity of urban house buildings is improved.

Description

technical field [0001] The invention belongs to the technical field of building frame structure control, and in particular relates to a rigid-flexible multi-defense line control method and a control structure for collapse and collision of adjacent frame structures. Background technique [0002] Due to the tight use of urban land resources and the requirements of building a conservation-oriented society, the distance between adjacent buildings is often small. If an earthquake occurs, the building will bear a certain external load. Once one of the adjacent buildings collapses due to column failure, It is very likely to hit the surrounding buildings, and the dynamic response of the adjacent buildings will be significantly amplified at the moment of impact, which will increase the probability of damage to the outside world such as earthquakes. In addition, the existing post-seismic damage indicates that adjacent buildings have collided After that, the components at the collision...

AI Technical Summary

Problems solved by technology

[0003] (1) Collapse of adjacent buildings is not considered in the collision problem;

[0004] (2) Collapse will have an extremely adverse impact on the dynamic response of adjacent buildings, but there is a lack of research on the collapse control of adjacent buildings

[0005] (3) There is a lack of measures for multiple lines of defense in the collapse and collision control of adjacent buildings
