Steel Structure Space Frame Of Inner Mongolia Round Library
raw material Q235B welded pipe / total height is 38 meters / total span is 88 meters / total length is 366 meters
1. The space frame design adopts the tube structure computer-aided design and manufacturing system 3D3S (version 14.0) software design to carry out the internal force analysis of the members and the automatic design of the full stress on the microcomputer, and the self-weight load of the space frame architecture is automatically superimposed in the internal force analysis.
2. The calculated length of the rod is L0=L, and the slenderness ratio of the key rod is tie rod ≤ 200 and compression rod ≤ 150. The slenderness ratio of other rods is tie rod ≤ 250, pressure rod ≤ 180.
3. The coordinate system of this project is a space rectangular coordinate system, and the positive direction is specified as follows:
The X direction is positive from left to right in the floor plan, the Y direction is positive from bottom to top, and the Z direction is positive from the ground to the sky.
4. Without permission, any loads (including construction loads) are not allowed to act on the space frame structure member, but must act on the ball joints, and the load value in the use stage cannot exceed the design value.
5. The unit of length not noted in this set of drawings is: mm, the unit of elevation is: m, and the unit of the reaction force of the support and the internal force of the rod is: kN. The internal force of the rod is positive and the pressure is negative.
