EXPERIMENTAL RESEARCH ON THE MECHANICAL PROPERTY OF FLEXIBLE JOINT OF UNDERGROUND UPVC WATER SUPPLY PIPELINES

摘要

The code performed at present applies only to the connectivity reliability of water supply pipelines and don't consider their seismic requirement. This paper analyzes the experimental data to fit the formula for relationship between the force and the displacement of the joint. This formula is obtained by the least square method. The formula developed can satisfy the actual requirements.
