Experimental research on fatigue properties of welded fabric

Gu Wanli1，Lim Chinloon2(1 China Academy of Building Research, Beijing 100013, China；2 Xinglian Steel Mesh(Shenzhen) Co., Ltd., Shenzhen 518106, China)

Abstract:The expression of fatigue S-N curves of welded fabric, fatigue test conditions and  failure features of specimens were introduced. By fatigue test results of welded fabric and analyzing part of abroad data, using stress range as main parameter and 95% as guaranteed probability, fatigue S-N curve equations of welded fabric were put forward and compared with curves in foreign codes. The fatigue S-N curve equations basically reflect fatigue properties of cold-rolled ribbed steel fabric.These can be reference to editing concerning codes and engineering application. In accordance with abroad experiences, a few typical welded diagrams of welded fabric reinforced in slabs reffered cycle load were introduced.

Keywords:welded fabric; cold-rolled ribbed steel wires; fatigue S-N curves
