裂缝荷载 meaning in English

cracking load under tbree-edge bearing test

On the basic of former research men ' s experience , 18 experimental members ( including 9 simple beams and 9 restrained beams ) are designed and tested . in the experiment , phenomena are observed and record by taking photos in the whole process from the first crack appears to test members crash completely , experimental data is attained including load values of crack - appear load , critical load and terminal load , stress values of reinforcing steel bar stress , compressed concrete stress and beam flank stress and values of deflection etc . by analyzing the crack ' s appearing and developing form and stress values of concrete and steel bars , the crash modes of test beams are defined ; shearing force - deflection curves are contrasted and analyzed ; the effects on shear strength of the three factors as shear span ratio , concrete strength and restraining moment are also analyzed
借鉴已有试验的经验，本文设计和完成了对18根超高强混凝土无腹筋梁（包括9根简支梁和9根约束梁）在集中荷载下抗剪强度的试验，观察了试件从裂缝出现到完全破坏失去承载能力全过程的试验现象并通过拍照进行记录，获得了试件的斜裂缝出现荷载、临界斜裂缝荷载和极限荷载等荷载值和纵筋应变、混凝土受压应变和梁侧混凝土应变等应变值以及挠度值等。
