Problems solved by technology

Although BRB can provide lateral stiffness, reduce the structural displacement angle, and consume energy at the same time; but it can only consume energy in moderate and large earthquakes, and its energy dissipation effect is not as obvious as that of viscous damping walls, and its cost is high

Embodiment 1

[0036] Such as Figure 6-8 Shown is a five-storey high frame structure system used in high-intensity areas according to the present invention. Firstly, the stress situation of the multi-storey building system is simulated and calculated by finite element design software to find out the height of each floor. In the part where the maximum interstory displacement angle is greater than 1 / 550 under the condition of small earthquake, and the part where the maximum interstory displacement angle is greater than 1 / 50 under the condition of large earthquake, a total of 12 walls with the same plane position are determined for each floor The shock-absorbing and energy-dissipating components are set, and the 12 walls are symmetrically distributed in the corner areas at both ends of the frame structure system and nearby positions. Such as Figure 6 In the first-floor half-frame structure system shown, the shock-absorbing and energy-dissipating components set on the six walls are single res...

Embodiment 2

[0041] In Example 2, the structural dynamic time-history analysis method is used to analyze the 8-degree small earthquake, moderate earthquake and large earthquake respectively compared with the frame structures under the other three working conditions. Seven groups of seismic waves are selected, including 5 actual waves and 2 artificial waves. Wave, the revised seven seismic wave seismic influence coefficient curves, the peak value of seismic input acceleration for small earthquakes is 70Gal, the peak value of seismic input acceleration for moderate earthquakes is 200Gal, and the peak value of seismic input acceleration for large earthquakes is 400Gal. SAP2000 calculation software is used to calculate and analyze the interstory displacement angle and the average value of story shear force.

Abstract

The invention provides a frame structure system suitable for a high-intensity area. The frame structure system is a multi-layer building composed of columns, beams and plates. In the frame structure system, the parts where the interlayer displacement angle is maximum due to intensive stress are provided with shock-absorption and energy-dissipation components respectively, and the shock-absorptionand energy-dissipation components include viscous damping walls and buckling-restrained braces, wherein the buckling-restrained braces are arranged at the positions where the interlayer displacement angles are maximum or relatively large due to intensive stress on the first to third floors of the multi-layer building or in the walls nearby the positions, and the viscous damping walls are arrangedat the positions where the interlayer displacement angles are maximum or relatively large due to intensive stress on the third or higher floors of the multi-layer building or in the walls nearby the positions. According to the frame structure system, while a good shock-absorption and energy-dissipation effect is achieved in a large earthquake, a moderate earthquake and a small earthquake, the aimscan be achieved that the sizes of reinforced concrete frame beam columns in the frame structure system are obviously reduced, the total construction cost of building materials is low, and the earthquake-proof cost-performance ratio is high.

Description

technical field [0001] The invention relates to a frame structure system, in particular to a frame structure system used in high-intensity areas. Background technique [0002] The frame structure is a structural system composed of columns, beams, and plates. The frame is composed of beams and columns, which jointly resist horizontal loads and vertical loads that occur during use. The walls of houses with frame structure are not load-bearing, and only play the role of enclosure and separation. Generally, prefabricated aerated concrete, expanded perlite, hollow bricks or porous bricks, pumice, vermiculite, ceramsite and other lightweight plates are used to build or assemble made. Frame structure buildings are flexible in space separation, light in weight, and save materials; they have the advantages of being able to flexibly match the building layout and rationally utilize and arrange a large building space, and are widely used in public buildings. [0003] In high-intensity...
