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 heightof 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.

The invention relates to the field of building structures. The double steel pipe concrete beam-column node with a built-in FRP tendon connection device of the present invention includes double steel pipe columns, I-beams, node connectors, inner braces and outer ring plates; the double steel pipe columns include inner steel pipes and the outer steel pipe; the node connectors include connecting the inner pipe and connecting the outer disk, both of which are round steel pipes; the inner support is a columnar structure, and bolt holes are evenly distributed along the circumference at both ends; the outer ring plate includes mutual The vertical horizontal part and the ring part; the upper and lower double steel pipe columns are connected by node connectors and inner supports. The inner pipe and the inner steel pipe are fixed in the bolt holes of the inner support. The invention utilizes the superior tensile performance and fatigue load resistance capacity of FRP tendons to effectively improve the seismic energy dissipation capacity of nodes and enhance the safety and bearing capacity of the structure.
