抗弯疲劳 meaning in Chinese
resistance to bending fatigue
Examples
- The fatigue experiment of six recycled coarse aggregate concrete beams and one ordinary concrete beam has been made
对6根再生粗骨料钢筋混凝土梁及1根普通钢筋混凝土梁的抗弯疲劳性能进行了试验研究。 - Beams are researched , and the relation between strains of corroded re - bars and fatigue life of beams are obtained . the main research contents and conclusions are as following : 1 . under the fatigue loads , the overstrain of concrete approximately coincidences three stages strain development and accumulation rule , and the mechanical property of concrete is deteriorated
鉴于实际工程中大量存在腐蚀钢筋混凝土结构承受反复荷载作用,但其力学性能研究不多的问题,本论文进行了锈蚀钢筋混凝土梁抗弯疲劳试验,研究了应力比和钢筋锈蚀率对锈蚀钢筋混凝土梁抗弯疲劳性能的影响,得出了锈蚀钢筋的应变与构件疲劳寿命之间的关系曲线,主要研究内容及结论如下: ( 1 )在循环荷载下,混凝土残余变形基本符合三阶段变形规律,力学性能劣化,疲劳损伤积累。
