电测法测定工字梁的正应力试验

The Experiment to Determine Direct Stress on "I" Girder by Electrometic Method

本试验主要通过电测法测定 :工字梁在弯曲时横截面上的正应力分布 ,并与理论值比较 ,以验证弯曲正应力公式 ,并且对材料合理选用进行分析。

The direct stress distrilouted on the cross-section of flexed 'I' girder has been determined with electrometic method in this paper.The porpose of the experiment is to verify the direct stress formula and to analyse material selection.
