Full-Scale Experimental Research on PE Sheathing of Stay-Cable

CODEN: JTEVAB

Abstract

The polyethylene (PE) sheathing of a stay-cable is easily damaged during the setup process due to the incorrect clamping choices, improper rubber blankets for the clamp, or inappropriate clamping force. In this paper, a full-scale experiment was carried out to study the compressive and tensile performances of the high-density PE sheathing during clamping. The clamping force, the length of the clamp, and the type of the rubber blankets used for clamping were evaluated in full-scale tests on Su-Tong Yangtze River Bridge, which is the cable-stayed bridge of the largest span in the world. During the setup process of the stayed-cables of Su-Tong Yangtze River Bridge, neither the cable clamp sliding nor the PE sheathing crushing occurred.
