Embodiment Construction
[0031] like figure 1 As shown, a cable bracing includes a reinforced concrete frame 1, and the reinforced concrete frame 1 is composed of a first column 11, a second column 12, and a pole that is arranged at the top of the first column 11 and the second column 12 and connects the two columns. Composed of a beam 13, it is characterized in that the brace includes a cable 2, two steering devices 3 and an elastic member 4 installed on the beam 13 and providing constraints along the horizontal direction of the cable 2, and the two steering devices 3 are installed on the beam 13 and the horizontal direction of the cable 2 respectively. The inner side of the junction of the two uprights; one end of the cable 2 extends obliquely from the bottom of the first upright 11 to the steering device 3 on the top of the second upright 12 , and turns back through the steering device 3 on the top of the second upright 12 . The elastic member 4 extends to the steering device 3 on the top of the fi...

The invention belongs to the technical field of construction engineering, in particular to a cable brace and an application method thereof. In the present invention, one end of the cable extends obliquely from the bottom of the first column to the steering device at the top of the second column, and turns back through the steering device at the top of the second column and then passes through the elastic member to extend to the steering device at the top of the first column. , and then turn back from the steering device at the top of the first column and extend obliquely to the bottom of the second column, thus forming a cross-shaped arrangement. The cables provided in the present invention can provide the self-resetting force for the building frame, and the elastic components provided can provide the building frame with hysteretic energy dissipation capacity and self-resetting force, and the two work together to help reduce the peak displacement and residual value of the building frame. Displacement; and the present invention takes up little space, can be used for the design of new buildings, and can be used for reinforcement and transformation of old buildings, and the construction is simple and convenient.
Description
technical field [0001] The invention belongs to the field of construction engineering, in particular to a cable brace and an application method thereof. Background technique [0002] In our country, diagonal braces are widely used in anti-seismic construction engineering. According to whether the braces are under pressure, they can be divided into buckling-resistant braces that can be both compressed and tensioned, and cable braces that can only be tensioned. Normally, the braces increase the lateral stiffness of the frame and reduce the interstory displacement of the building by providing lateral resistance. [0003] For anti-buckling bracing, due to its large cross-sectional size, the rigidity of the diagonal bracing is relatively large, so the use of anti-buckling bracing in the building structure will significantly increase the lateral stiffness of the structure. Although this can effectively restrain the interstory displacement of the building, it will also lead to a ...
