Abstract
The invention discloses a bearing structure of a three-dimensional garage with an energy-consumption truss lateral-resistance form vertical-lifting type high-rise steel structure. A lateral-resistance component of horizontal force in the bearing faces of upright faces at both sides of the structure of the three-dimensional garage comprises energy-consumption trusses arranged layer by layer. Each energy-consumption truss comprises an upper chord member, a lower chord member, two upright web members and two diagonal web members, wherein all the web members are symmetrically arranged, the height of the trusses is the same as the height of a structural layer, and the trusses are leveled with the structural layer; the upper chord member and the lower chord member are both continuous chord members, and both ends of each continuous chord member are rigidly connected with corner posts; the two upright web members are vertical to the upper chord member and the lower chord member, both ends of each vertical web member are respectively hinged with the upper chord member and the lower chord member, and the distance of the two upright web members is 1/8 to 1/4 times the height of the trusses; one end of each diagonal web member is hinged at the position of the connecting joint of the upper chord member and the corner posts, and the other end of each diagonal web member is slantways hinged at the position of the connecting joint of the upright web members and the lower chord member downwards; and thereby, a shearing energy-consumption section the length of which is 1/8 to 1/4 times of the height of the trusses is formed at the middle parts of the upper chord member and the lower chord member of the energy-consumption trusses. By the invention, the structure has better shock resistant performance and sufficient lateral-resistance rigidity; and meanwhile, by the interlayer arrangement of the trusses, mechanical equipment in the garage is convenient to hang and install laterally.
Description
Technical field
The present invention relates to a kind of urban parking area, specifically a kind ofly be used for the vertical lift type high-rise steel structure multi-storied garage load-carrying members that the city dolly is parked.
Background technology
Along with the fast development of China's rapid economic development and auto industry, the popularity rate of family expenses car improves rapidly in the city.Because the parking lot construction in city does not catch up with the growth of car quantity far away, make that the contradiction of vehicle parking is becoming increasingly acute in the city.Floor space is little because the high-rise steel structure parking systems has, appearance car rate height, easy construction, and characteristics such as storing and taking out car required time weak point, bicycle parking safety become the preferred option that China big and medium-sized cities solve parking problem.The vertical lift type storied 3-D garage parking that is used to park car that has built up at present, form by the winding shaft of centre and the parking space of both sides, its load-carrying members generally adopt each layer of four sides to be abound with the frame system of center support, perhaps adopt unsupported pure frame structure.The former anti-side rigidity is big, but anti-seismic performance is relatively poor, and the rod member numbers of poles is many, the on-site installation work amount is big, and in addition, each layer of four sides is abound with to support and is unfavorable for that plant equipment lifting is from the side installed in the garage, will prolong the construction period, be unfavorable in the city that prosperity is crowded, installing and build.Unsupported pure frame type garage support framework has bigger ductility, the anti-seismic performance energy, but anti-side rigidity is little, lateral displacement is big, second-order effects is remarkable, easily cause the destruction of non-structural element, excessive lateral deformation easily causes lifting, transverse-moving mechanism to lose stable working environment and operation troubles occurs.Anti-side of coordination structure and anti-seismic performance solve storied 3-D Garage lifting, crossing system stable operation environment problem, become the problem that solution is needed in the fast development of high steel work parking systems badly.
Summary of the invention
The objective of the invention is to according to the deficiencies in the prior art, a kind of novel load-bearing skeleton structural system that is suitable for vertical lift type high-rise steel structure multi-storied garage is proposed, this structural system can coordinate well the anti-side rigidity of high-rise steel structure multi-storied garage and anti-seismic performance, simultaneously can Convenient garage in plant equipment from the side hang in installation.
Technical scheme of the present invention is: the corner post that comprises four jiaos of load-bearing skeletons, the center pillar of front and back facade, vertically frame is set a roof beam in place, X-shaped before and after being arranged between the facade center pillar supports, the intermediate lateral Vierendeel girder, the anti-side member of structure two side elevations, the winding shaft in the middle of constituting and the parking space of both sides, structure laterally is about 6 meters, vertically be about 7.8 meters, floor height is 2.0～2.4 meters, it is characterized in that, the energy-consumption truss that the anti-side member of described structure two side elevations is arranged by interlayer constitutes, described energy-consumption truss is by last, lower chord and two perpendicular web members and two diagonal web members constitute the equal symmetric arrangement of all web members; Described upper and lower chord member is continuous chord member, described two perpendicular web members are arranged in energy-consumption truss middle part and vertical with upper and lower chord member, its two ends are hinged with upper and lower chord member respectively, two perpendicular web member spacings are 1/8～1/4 times of depth of truss, described diagonal web member one end is hinged on the connected node place of upper chord and corner post, and the other end is oblique hinged at perpendicular web member and lower chord connected node place downwards; Thereby form an empty stomach section between the two perpendicular web members of energy-consumption truss middle part, the upper and lower chord member of energy-consumption truss constitutes the shear energy dissipation section in intersegmental on an empty stomach part.
Described energy-consumption truss height is identical with the structure floor height, and truss is concordant with deck.
Described upper and lower chord member two ends and described corner post rigidly connect.
Vertical lift type high-rise steel structure multi-storied garage load-carrying members of the present invention, because the existence of its lateral resisting truss middle part shear energy dissipation section, under Horizontal Seismic Load, the shear energy dissipation section can at first be sheared plastic strain, earthquake energy, alleviate or avoid the destruction of other structural element, increased the energy dissipation ability of structure, the existence of truss also provides enough anti-side rigidity for structure.In addition, the truss interlayer arranges, be convenient to plant equipment in the garage from the side hang in installation, easy construction; The span of truss and height dimension have determined that the angle between interior diagonal web member of truss and the chord member is also more moderate.
