Decentralized anti-buckling bracing and its construction method

Abstract

The invention discloses a reinforcing steel bar regional scattered buckling-restrained brace and a construction method thereof. The reinforcing steel bar regional scattered buckling-restrained brace comprises a core stress unit, an external restraining unit and isolation layer units, wherein the core stress unit comprises a plurality of reinforcing steel bars penetrating through the external restraining unit and two connector units; the isolation layer units which are connected with the external restraining unit into a whole body are respectively arranged between each reinforcing steel bar and the external restraining unit; each reinforcing steel bar is not bonded with the corresponding isolation layer unit, and the part, extending out of each side of the external restraining unit, of the reinforcing steel bar is connected with one connector unit into a whole by virtue of an energy consumption reinforcing body. The construction method comprises the steps of firstly producing the external restraining unit, and then inserting the reinforcing steel bars into the isolation layer units; and finally installing the energy consumption reinforcing body and the connector units. By adopting the reinforcing steel bar regional scattered buckling-restrained brace, when an earthquake happens, the inertia force acting on a supported structure is remarkably reduced, the displacement response and acceleration response of the supported structure can be alleviated, and the damage degree of the supported structure is reduced.

Description

technical field [0001] The invention relates to an anti-buckling support and a construction method thereof. Background technique [0002] my country is one of the land-earthquake-prone countries. Especially in recent years, large earthquakes have occurred frequently, and the damage to buildings caused by earthquakes has become more and more serious. Reducing casualties and economic losses caused by structural damage is the source of structural engineering technicians. Responsibilities and obligations. The frequent occurrence of earthquake disasters and the improvement of people's demand for life and property protection have put forward higher requirements for the anti-seismic level of buildings. Usually, some additional components, such as anti-buckling braces, are set in the building structure to increase the structural stiffness and overall damping, so as to consume seismic energy and improve seismic safety. In order to prevent the local and overall instability of the ste...

Problems solved by technology

Existing anti-buckling bracing core stress units mostly use section steel with various cross-sections. Due to the high quality of the section steel, installing a large number of this type of buckling-resistant bracing in the structure will result in a large inertial force under the action of the earthquake, which is not suitable for Widely used in super high-rise and long-span structures
