裂缝间距 meaning in Chinese
fracture interval
split spacing
Examples
- The formula in code can be used to estimate the width , space between cracks and the deflection
并对裂缝间距、裂缝宽度进行了统计分析,结果表明,裂缝间距、裂缝宽度的分布符合正态分布。 - It is shown that the proposed model can not only take the ratio of reinforcement , the material properties of reinforcement and concrete and the crack spacing into account , but also be easily incorporated in finite element programs
该模型不仅有效地反映了配筋率、裂缝间距以及钢筋和混凝土材料特性等因素对钢筋混凝土开裂后性能的影响，并且很容易在现有的有限元程序中实现。 - ( 3 ) to discuss thereasonable section shape of the continuous composite beam . the works of this paperare as follows : ( 1 ) contrast the cracking course of the concrete beam and the composite beam , atthe point of the bending state of the beams , put forward the crack width mode : bending curvature 、 crack height 、 the distance between crack
据此,本文的主要研究成果如下: ( 1 )通过分析、对比普通混凝土梁和组合梁负弯矩区裂缝出现、发展过程,以构件受弯状态为出发点,提出了以弯曲曲率、裂缝高度、裂缝间距为主要参数的裂缝宽度计算模式。 - A way to avoiding crack or reducing crack width of concrete or reducing distortion of member is using prestressed concrete . the writer tried to make full use of the merit of the prestressed concrete and designed prestressed concrete mandril to control crack of structure . the prestressed concrete mandril , which was firstly applied high pressure on a small concrete bar , and then was made in concrete , so it would act as reinforced bar and resist load . in this thesis the writer designed 24 mmnbers and had experimental study of them , reached the conclusion that the effect of resisting crack of the prestressed concrete mandril was good when the load was not large , it can enhance the capacity of resisting crack and reduce the crack distance and crack width , but when the loads was large , the effect of resisting crack was not good , when we used the prestressed concrete mandril and reinforced bar together in member , the effect of resisting crack was very good . the writer analysed the adherence mechanism and wreck mechanism of the prestressed concrete mandril in anxial tension members , and according to the character of the prestressed concrete mandril , the writer constructed the bond model of it . then the writer introduced the analysis theory of crack including the bond - slip theory , the non - slip theory , the synthesis theory and mathematics stat method . the different theory had different theory base , they considered that the primary affection of crack width was different . in this test , the crack distance and crack width of members which placed reinforced bar were match to the compute value of the code gb 50010 - 2002 very well . to the members which
本文共进行了24根试件的试验研究,得出了预应力混凝土芯棒能较大地提高构件抗裂承载力,在荷载小于预应力混凝土芯棒的开裂荷载时有较好的抗裂效果,能较大地减小裂缝间距和裂缝宽度,但是当荷载较大预应力混凝土芯棒开裂时预应力混凝土芯棒的抗裂效果不是很好,若将普通钢筋和预应力混凝土芯棒一起使用时则有很好的抗裂效果。本文分析了预应力混凝土芯棒在轴拉试件中的粘结机理和破坏机理,根据预应力混凝土芯棒本身的特点,提出了预应力混凝土芯棒与后浇混凝土之间的粘结模型。然后本文详细介绍了经典的裂缝分析理论粘结滑移理论、无滑移理论、综合理论和数理统计方法,各理论有着各自不同的理论基础,认为影响裂缝宽度的主要影响因素也各不相同。 - ( 2 ) base on the crack width mode , separately establish formula of the bendingcurvature 、 crack height 、 the distance between crack , and compost the formula of thecrack width . and put the experiment data of others literature into the formula , thecalculated result also show good agreement with the experiment data
( 2 )在上述模式的基础上,分别建立使用荷载下曲率计算、裂缝高度取值及裂缝间距计算的公式,由此形成最终裂缝宽度计算公式,该公式概念清楚、计算简单,并引用其他文献的试验数据代入公式,计算结果与试验数据吻合较好。
