［摘要］介绍了钢筋焊接网疲劳S-N曲线的表达方式、疲劳试验条件及试件破坏特征。通过对此次焊接网疲劳试验结果及国外部分数据的分析，以应力幅作为主要参数，取95%的保证概率，得出钢筋焊接网疲劳S-N曲线方程，并与国外的规范曲线进行比较。给出的疲劳S-N曲线方程基本反映了冷轧带肋钢筋焊接网的疲劳特性，可为有关标准规范的编制及工程应用提供参考。根据国外经验，介绍了疲劳荷载下的板类构件，给出了提高抗疲劳性能的几种典型施焊图例。

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
