Embodiment 1

[0077] This embodiment describes the layout strategy of the shear wall.

[0078] (1) Project overview

[0079] In an 8-degree area, the design basic seismic acceleration is 0.30g, a Class II site. It is proposed to build a 10-story frame-supported shear wall structure, of which the bottom two floors are frame-supported floors, and the plane of the frame-supported floors is shown as figure 1 shown. The 3rd to 10th floors are the upper floors with a floor height of 3600mm. Among them, the strength grade of the structural columns and shear walls of the frame support layer is C40, and the strength grade of the beam slab concrete is C30; the column section size of the frame support layer is 650×650mm, and the wall thickness is 200mm. Take the height of the frame support layer as 5000mm, by the frequency equation |k-ω 2 m|=0, at this time, the natural frequency ω of the frame-support layer n It is close to the characteristic frequency ω of the site, and installing the viscous l...

Embodiment 2

[0092] (1) Project overview

[0093] In a 7-degree area, the basic seismic acceleration is 0.15g, and a 15-story high-rise building is proposed to be built; the bottom 2 or 3 floors will be used as shopping malls, and the upper floors will be used as apartments. Considering the frame-supported shear wall structure system, it is proposed to install viscous liquid dampers on the frame-supported layer to ensure the safety of the structure under earthquake action. The structure layout of the frame support layer is still as follows figure 1 As shown, the cross-sectional size of the frame pillar is 800×800mm, and the concrete strength is C50; the upper shear wall layout is as follows Figure 5 As shown, short-leg shear walls with a height-to-thickness ratio of 5 are used except for the four corners, the wall thickness is 250mm, and the concrete strength is C40. end post.

[0094] The thickness of the floor slab and the size of the transfer beam refer to the requirements of the "H...

Abstract

The invention relates to the technical field of energy dissipation and vibration reduction buildings, and provides a framed shear wall structure and a designing method thereof. The framed shear wall structure comprises bottom frame support layers and an upper floor which is located above the frame support layers and supported by the frame support layers. The number of the frame support layers is two or more, and dampers are at least arranged on the two frame support layers on the bottommost portion. A shear wall is arranged on the upper floor. Compared with the mode of improving the structural strength for 'seismic resistance' of parts of framed shear walls, more advantages can be achieved by using the dampers for absorbing or consuming seismic energy, and thus the buildings can be better protected. Besides, the dampers can be turned into 'fuses' of the structure, only the devices need to be replaced when violent earthquakes happen, the using function of the buildings cannot be interrupted, and the whole life cycle cost of the structure can be reduced easily. In addition, the dampers can be flexibly arranged on the frame support layers, the influence on building space is reduced to the greatest extent, hence, the building space of a lower floor can be better released, and expectant commercial value can be helped to be achieved by constructors.

Description

technical field [0001] The invention relates to the technical field of energy dissipation and vibration reduction buildings, in particular to a frame-supported shear wall structure and a design method thereof. Background technique [0002] In recent years, in order to pursue more commercial interests, builders often plan the functions of a building differently along the height. The upper floors are used as hotels and residences, and the lower floors are used as shopping malls, restaurants or cultural and entertainment facilities. Hotels and residences need to arrange more walls, so it is more appropriate to use a shear wall structure; while shopping malls, restaurants and cultural and entertainment facilities need as much free and flexible indoor space as possible, a frame structure is most suitable. From this point of view, the frame-supported shear wall structure is the most ideal structural form to realize this building function. [0003] The frame-supported shear wall ...
