principal tensile stress

Example Sentences:

	1.	A linear programming model for the shape optimization of arch dams is established to minimize the maximal tensile stress of the arch dam 摘要以最大主拉应力最小作为目标函数，建立了拱坝体型优化设计的线性规划模型。
	2.	The influence of relative cover c / d on corrosion failure model and maximal principal tension stress , the position of rebar located , corrosion of adjacent rebar induced additional stress are considered in this model 模型中考虑相对保护层厚c d对锈胀破坏形态和钢筋周围混凝土最大主拉应力的影响，并且考虑了钢筋位置不同以及相邻钢筋锈蚀产生附加应力的影响。
	3.	Based on the above , the three dimensional stress of the box girder with different dimensions are analyzed . by analyzing the result of above seven working situation , some conclusions are given out . the main tensile stress of in diaphragm is very large 通过对以上七种工况计算结果的分析，认为在双箱单室箱形主梁中，横隔梁中产生的主拉应力很大，受力极为不利。
	4.	By fitting reasonable external prestressing tendons to ensure ultimate bearing capacity of the bridge , to ensure stress reserve of the main beam , to reduce effectively principal tensile stress , to renew line state of bridge structure and gradient 通过合理地设置体外预应力束，确保了该桥的极限承载能力；增大了主梁的应力储备；有效地减少了主拉应力；恢复了桥面线形和坡度。
	5.	A bearing surface transmits the interaction between an arch dam and its foundation , the strength of which directly affects the constraint of the bedrock to the dam , and thus affects the stress and deformation of the dam . the influence is studied in this paper with nonlinear finite element method , as an example , for a high arch dam in design . the results show that the influence on stress is only limited within the local area near the bearing surface , larger on the maximum principal tensile stress than on the principal compression stress , and the decrease of the strength does not cause unlimited increase of the maximum stress . the influence on the displacement of the top of the dam is smaller than that of the bottom of the dam , especially the relative downstream displacement . at the lower strength of the bearing surface , the relative downstream displacement at the bottom of the dam increases with the decrease of the strength 建基面是传递拱坝和基岩相互作用的纽带，它的强度直接影响基岩对坝体的约束，从而影响坝体的应力和变形.采用非线性有限单元法，以设计中的某高拱坝为例，分析建基面强度对坝体应力和变形的影响.结果表明建基面强度对坝体应力的影响仅限于建基面附近的局部范围，对最大主拉应力的影响要大于对最大主压应力的影响，建基面强度的降低不会无限地增大坝体的应力数值；建基面强度对坝顶位移的影响较小，但对坝底位移(尤其是顺河向相对位移)的影响较大，当建基面强度较低时，坝底顺河向相对位移随建基面强度的降低而增大
	6.	The tendons in the top and the base plate have an effect , namely “ opposite tension ” , on the web . moreover , it is found that the web prestressed reinforcement is necessary since it is capable of lowering the principal tensile stress . the reinforcement arrangement without the web prestressed reinforcement is not mature in theory since its disadvantages are not solved in practice 底板索和顶板索对腹板存在着明显的“对拉”作用,同时,下弯索有效的克服了腹板的主拉应力,设计中是不可少的,不设置下弯索的布索方案在理论上还不够成熟,实践证明该布索方案也存在着许多的弊端。
