prestressed reinforcement meaning in English
预应力钢筋
Examples
- Some effective measures were presented to solve bigger prestress loss of mid span in overlong frame and it is suggested that prestressed reinforcement with curve linetype should be adopted in slabs if possible
在次梁与板中为有效利用无粘结预应力筋，建议在板厚许可的情况下尽量采用曲线形预应力筋。 - Abstract : the relations between prestressed reinforcements in two directions and the total balance loading of unbonded prestressed dual concrete slabs are established in the present paper based on the analysis of projects , in which the structural cost is optimized satisfying the requirements of the service state , the ultimate state and constructions
文摘:本文在对无粘结预应力双向板两个方向平衡荷载分配方案分析的基础上，建立了以两个方向预应力筋面积与总平衡荷载的关系式，在满足极限状态、正常使用极限状态和构造要求的条件下，使结构的造价达到最佳。 - The relations between prestressed reinforcements in two directions and the total balance loading of unbonded prestressed dual concrete slabs are established in the present paper based on the analysis of projects , in which the structural cost is optimized satisfying the requirements of the service state , the ultimate state and constructions
本文在对无粘结预应力双向板两个方向平衡荷载分配方案分析的基础上，建立了以两个方向预应力筋面积与总平衡荷载的关系式，在满足极限状态、正常使用极限状态和构造要求的条件下，使结构的造价达到最佳。 - In light of the simulative research results , three methods are applied to analyze some controversial problems in this kind of structural system ( such as the concrete pouring sequence of continuous ends , the applying sequence of pretensioned force , the removal of the temporary supports , the concrete pouring style of continuous ends , the optimization of constructional reinforcement and prestressed reinforcement ) . some important conclusions are drawn : the concrete pouring sequence of continuous ends should be in accordance with the principle of " interval end " ; the removal of temporary supports is also on this principle ( opposite to traditional opinions ) . at the same time , other problems such as the shrinkage and creep effects of concrete , the c racking and failure pattern , the optimization of reinforced bars and prestressed bars are also analyzed in detail
在此基础上，对于目前先简支后连续结构体系中存在的一些有争议的问题(如后连续端部浇筑和后连续预应力张拉的顺序、体系转换中的临时支座拆除顺序、后连续端部浇筑方式、后连续端部的预应力筋及普通钢筋的优化等) ，我们分别运用三种方法进行了细致的模拟分析、研究，并得出了一些具有重要工程意义的结论：后连续端部的浇筑顺序和后连续预应力张拉的“隔跨”原则，临时支座拆除的“隔跨”原则(此前人们一直认为“对称浇注和对称张拉”是最为合理的施工工序) ，混凝土的收缩、徐变对先简支后连续结构体系的影响一般较小等。 - 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。
