Cable net-reinforced concrete frame structure and manufacturing method

Abstract

The invention provides a cable net-reinforced concrete frame structure and a manufacturing method. The structure comprises a reinforced concrete frame structure, and in the reinforced concrete frame structure, two groups of obliquely intersected steel cables are connected in a plane grid formed by a frame column and a frame beam to form a cable net; the two ends of each steel cable are connected with the frame column or the frame beam through anchoring devices. A cable net support of the structure belongs to a flexible support, the steel cables only bear tension, and buckling failure cannot begenerated; the steel cables in the two directions work alternately under horizontal loads in different directions, due to the large yield strength of the steel cables, the steel cables are in elasticdeformation during work, deformation of the steel cables basically disappears completely and recovers to the original shape when the steel cables quit work, and the self-recovery can reduce or eliminate residual deformation after an earthquake. It is very beneficial to maintain the normal use function of the structure after an earthquake.

Description

technical field [0001] The invention relates to a cable net-reinforced concrete frame structure and a manufacturing method, belonging to the technical field of building structures. Background technique [0002] The reinforced concrete frame structure has simple structure, clear force transmission, flexible space separation, and material saving. It is widely used in multi-story buildings, but its lateral stiffness is small. When the building height reaches a certain height, under the action of horizontal load, The frame will have a large displacement, which directly affects the use of the building, and the height of the building is therefore limited. In order to solve the problem of insufficient lateral stiffness of the reinforced concrete frame structure, rigid supports are often added to the frame structure to become a supported concrete frame structure. However, when a large horizontal load is encountered, the support system is prone to buckling instability. At this time ...

Problems solved by technology

[0002] The reinforced concrete frame structure has simple structure, clear force transmission, flexible space separation, and material saving. It is widely used in multi-story buildings, but its lateral stiffness is small. When the building height reaches a certain height, under the action of horizontal load, The frame will have a large displacement, which directly affects the use of the building, and the height of the building is therefore limited

In order to solve the problem of insufficient lateral stiffness of the reinforced concrete frame structure, rigid supports are often added to the frame structure to become a supported concrete frame structure. However, when a large horizontal load is encountered, the support system is prone to buckling instability. At this time The horizontal resistance of the structure will decrease sharply, causing the structure to fail

In order to prevent the buckling of the supporting concrete frame, the buckling-restrained braced frame structure has been developed, but the research on the buckling-restrained braced frame structure still needs to be in-depth, and the buckling-constrained braced structure is more complicated, the design is more complicated, the economic effect is not good enough, and the installation is not fast enough , it is also difficult to achieve light weight and stability

In addition, most buckling-restrained braces are not self-healing
