The seismic support of Baotou cable bridge is designed to simplify all aspects of the complex load reasonably. The corresponding calculation formula can be used to calculate the strength, stiffness, stability and other conditions in the seismic support of the pipeline waste. Let's talk about these conditions:
Strength conditions: The maximum stress at the single thin link of all components of the pipe-assembled seismic support should not exceed the corresponding allowable stress value at the design temperature. Be careful not to miss the strength control points of the seismic support and suspension components of each waste product and pay attention to the seismic resistance of the waste product. Determination of design temperature, material, allowable stress and load combination of supporting frame members.
Stiffness conditions: The maximum deflection of the fixed bracket and the limit bracket should not be greater than 0.2% of the calculated length of the beam and not greater than 1.6mm. The maximum deflection of other brackets should not be greater than 0.4% of the calculated length of the beam and not greater than 3.2mm
Seismic support stability conditions: The axially compressed rods in the pipe waste brackets need to be set as medium flexibility rods. For carbon steel rods, the limit slenderness ratio is set to 120. For two-arm cantilever or triangular brackets, the level should be considered. The effect of the load and the lateral stability of the stent, consider measures such as adding diagonal braces between the limbs to increase its lateral stability.
The seismic support supports the calculation of strength conditions, stiffness conditions and stability conditions in pipeline waste supports. The accuracy of these conditions needs to be rigorously and scientifically calculated. The accuracy of these conditions has a great influence on the role of pipeline waste supports and hangers.
