张拉控制应力 meaning in Chinese
control stress for prestressing
Examples
- ( 2 ) the crack load increases with the increase of the amount of the prestressing steel or the tensioning stress
( 2 )预应力筋用量的增加、张拉控制应力的增大使预应力框架梁、柱的开裂荷载提高。 - Influence of the amount of the prestressing steel and the tensioning stress to the crack load of the beam is greater than that to the crack of the column
并且预应力筋的用量和张拉控制应力对梁开裂荷载的影响要比对柱开裂荷载的影响要大得多。 - Additionally , modal parameters are tested under different prestressed forces and during the course of the lose of prestressed forces . finally , different vibration conditions , such as different rigidity of the hammer and different forces , are also studied
另外通过振动测试,对预应力梁在不同的张拉控制应力下、预应力损失过程、不同激励条件下构件的实测模态参数的变化规律进行了试验研究。 - The results indicate that the ratio of span to rise , the ratio of reinforcement and the stretching controlling stress are the three primary influencing factors to the failure pattern of the slab . in addition , the relationships between the ratio of deflection to span and the ratio of span to rise and the stretching controlling stress submit to linear curves , the relationship between the ratio of deflection to span and the ratio of reinforcement submits to a quadratic parabola curve
运用数值分析程序计算了175组不同跨高比、配筋率、张拉控制应力的中强( 1270mpa )螺旋肋钢丝预应力空心板，结果表明跨高比、配筋率、张拉控制应力是影响空心板破坏形态的主要因素，且构件挠跨比与跨高比和张拉控制应力呈线性关系，与配筋率呈二次抛物线关系。 - Taking an ultimate deflection more than 1 / 50 of calculating span as the determinant term , by the means of numerical analysis and regress equation respectively , this paper discusses the reasonable stretching controlling stress of usual span and reinforcement slabs for design reference
以极限挠度达到跨度的1 50作为延性破坏的判定指标，本文分别运用数值分析程序试算和回归方程得出了常用跨度、常用配筋的中强( 1270mpa )螺旋肋钢丝预应力混凝土空心板的张拉控制应力的取值，供设计参考。
