- Example Sentences:
| 1. | 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。 |
