Indoor stadium structure design

Support node layout and design
The overall structure of the asymmetry of engineering, and the eaves is higher, so playground equipment suppliers is the main component to resist lateral force in this project. The plane arrangement of the support has been shown in figure 7, longer expatiatory. Determined by calculation and lofting, between the column support, such as, steel tube support choose good direction, according to the articulated structure; Between pillars support section for phi 219 x 8; Because steel column is high, to reduce the calculation length of pillars, the elevation of 6.5 m long position and place on the roof set rigid tie bar, tie bar section for phi 133 x 6; Due to the characteristics of the structure of the project itself, C shaft stiffness weak shaft rigidity than B, so tong long set up at the eaves of C axis truss structural support to improve the longitudinal stiffness, the lower chord on cross section of p hi 114 x 4, section for phi 70 x 3 CHS. In order to ensure system integrity and effective transfer of horizontal load, is set in the plane outside the bottom chord of the truss arch lateral vertical support, set in the first quarter of the truss arch horizontal support, vertical level of support and supporting high strength round steel cable structure, the yield strength of 460 mpa, choose from 20 and 25 two lasso, make indoor arrangement is clear, uniform, beautiful roof indoor playground structures. Support connection nodes and cable connection node.
The main structure of key nodes design B and C axis adopt rigid connection steel column column foot, steel column base plate additional shear key to improve the level of resistance of column foot;
A shaft of 11 column foot and wind column column foot as hinged connection form; Corner column foot even met. Its main truss and the longitudinal truss node is using direct welding penetration, since there is no such node plate, steel saving, in order to ensure the cutting precision and welding quality of pipe end part, require the use of space fully automatic parabola.
Cutting machine for cutting processing, lower chord on truss are "K" type node; B axis longitudinal truss end connection with bolt splint fixation, main arch truss vertical and bottom chord truss and steel column connection with pin shaft connection, its processing production is relatively simple, in accordance with the calculation of Jane.
