Geometric dimension deviation of abutment/ Matters Attention
The deviation of the geometric dimensions of the supports shall conform to the provisions of the following sheet
Abutment capacity of bearing (kN)
Roof plane dimension deviation (mm)
Height deviation after abutment assembly (mm)
Matters Attention in Selection of Steel abutment for Space Truss
1. When selecting the abutment, pay attention to the size of bearing capacity, the size of vertical relay, the size of horizontal force, and pay attention to the displacement and rotation angle, and also pay attention to the horizontal elastic rigidity for the shock absorbing support. If the mechanical or geometric dimensions of the table support do not meet the design requirements, the design department may request that the company shall design separately.
2. Pay attention to the type of abutment, namely the two-way movable type, the one-way movable type, and the fixed type.
3. The damping abutment is given in terms of displacement and stiffness, which is the requirement of damping of the project.
