预应力度 meaning in Chinese
degree of prestress
Examples
- Fail modes which are influenced by prestressing levels , length of negative moment reinforcement and fire case are proposed
考察了预应力度、负筋长度及不同受火工况对破坏形式的影响。 - And studies show that prestressed concrete beams with high ppr have good displacement restoring capacity , better ductility and seismic performance as a whole
研究表明：高预应力度混凝土梁具有优良的变形恢复能力以及较好的位移延性，总体上抗震性能较好。 - According to hysteretic properties under low - cyclic loading and some other suggestions , the moment - curvature restoring force computation model of unbonded partially prestressed concrete section , which considering the ppr , is given
此外由于施加了预应力，使得该结构具有良好的恢复力特性。本文还根据试验结果和相关参考文献提出了考虑不同预应力度的预应力扁梁截面弯矩?曲率恢复力计算模型。 - Previous research showed that the unbonded prestressed concrete member has the similar ductility to the commom reinforced concrete member , while the energy - dissipating capacity is worse that can be found from the narrow hysteretic characteristic
以往的研究也表明：无粘结预应力混凝土构件具有与普通钢筋混凝土构件相近的延性，但其耗能能力随着预应力度的加大而有所降低，表现在滞回环的捏拢现象越来越明显。 - The main factors including concrete cover and prestressing levels which may have influence on the fire resistance of the simply - supported slabs are examined . the deflection and prestress are presented . from the results of tests , the fire endurance of the simply - supported slabs are given
在简支板的火灾行为试验研究中主要考虑了普通钢筋的保护层厚度和预应力度两个因素，主要测试了构件的挠度变化及预应力的变化，并由此得出了其耐火极限。
