Embodiment Construction

[0016] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0017] see Figure 1 ~ Figure 2 , a combined special-shaped column structure system using mild steel damping walls, including a frame structure composed of rectangular steel pipe concrete composite special-shaped columns 1 and H-shaped steel beams, and the upper H-shaped steel beams 2- 1. An upper cantilever wall 4 fixedly connected to a lower cantilever wall 5 fixedly connected to the lower H-shaped steel beam 2-2, and a mild steel damping wall 3 is connected between the upper cantilever wall 4 and the lower cantilever wall. The above-mentioned mild steel damping wall 3 has the ability to provide lateral stiffness under frequent earthquakes and yield energy dissipation under rare earthquakes, and it can effectively control the combined speci...

Abstract

The invention discloses a combined special-shaped column structure system using a soft steel damping wall. The combined special-shaped column structure system comprises a frame structure composted ofrectangular concrete-filled steel tube combined special-shaped columns and an H-shaped steel beam, the frame structure is internally provided with an upper cantilever wall fixedly connected with the upper layer H-shaped steel beam, and a lower cantilever wall fixedly connected with the lower layer H-shaped steel beam, and the soft steel damping wall is connected between the upper cantilever wall and the lower cantilever wall. According to the combined special-shaped column structure system, the additional damping ratio of the combined special-shaped column structure system can be effectively added, the earthquake action is reduced, interlayer displacement under the function of the horizontal load is reduced, and the application height of the combined special-shaped column structure systemin a high intensity area is added; yield energy consumption of the soft steel damping wallin case of a large earthquake can be realized, the earthquake damage of the main structure is relieved, aninstallation way of the soft steel damping wall is simple, and easy to exchange; and moreover, construction is simple, ductility and the energy consumption capacity are good, the assembled degree is high,construction is convenient and fast, wet construction on site can be effectively reduced, a construction period is shortened, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to a combined special-shaped column structure system, in particular to a combined special-shaped column structure system using a mild steel damping wall. Background technique [0002] Rectangular steel tube concrete combined special-shaped column structure system has the advantages of flexible layout, indoor exposed beams and columns, factory production, assembly construction, etc., and has been applied in low-rise and multi-storey buildings. However, due to the low lateral stiffness of the system, it is necessary to add more steel supports or concrete shear walls when it is applied to high-rise buildings with more than 18 floors in high-intensity areas. The arrangement of steel supports in many places brings inconvenience to the arrangement of doors and windows of the residence; the use of cast-in-place concrete shear walls requires a large amount of wet work on site and reduces the assembly rate. In order to further promote the...
