Pre-Tension Control Technology of Monolayer Cable Net Fixed by Elastic Structure Anchor

摘要

The elastic structure of the anchor-fixed monolayer cable net generates elastic displacement under pre-tension, so the designed tension of the cable can be consistent after repeated test and it is difficult to control in later construction. For this case, we get causes for elastic displacement based on comprehensive analysis, simulate and analyze it by using displacement compensation tension method to compute all initial tensions once time and guarantee consistent designed tensions after elastic distortion of a cable. We make the construction sequence and record the force and tension of each cable after it is strained in place based on computed initial pre-tension in order to monitor if the distortion is reasonable in tension and guarantee in-place tension in construction once time without repetition.
