precast prestressed beam meaning in English
预制预应力梁
Examples
- The results show that the performances of precast prestressed beam - to - column concrete connections with unbonded tendons are equal or superior to that of a monolithic connection in terms of ductility and displacement - restoring capacity
结果表明，无粘结预应力装配式混凝土框架连接具有良好的耗能能力，在延性和变形恢复能力上比现浇连接更优。 - Subassemblage and prestressed concrete frames are assembled by precast prestressed beams and columns with tendons in the joints of the frames . these beams and columns are hoisted in site and the tendons are passed through the moire pipes . so prestressing force are brought to the joints of the frame . these tendons also can assume the moments at the end of the beams in ordinary condition
预压装配式预应力混凝土框架是采用工厂化生产的预制柱和预制预应力梁，运至现场直接吊装，梁柱就位后，将后张预应力筋穿过梁柱预留孔道，对节点实施预应力张拉预压。 - Subassemblage and prestressed concrete frames are assembled by precast prestressed beams and columns , which are made in the factories , with tendons in the joints of the frames . so the joints and frame are monolithic and continuous , consequently , this kind of frame systems possess higher reliability and solve the problems in the process of assembling , exploring a new way for industrial production of prestressed structures
预压装配式预应力混凝土框架是采用工厂化生产的预制柱和预制预应力梁运至现场安装，并对节点实施二次预应力张拉，构成整体受力节点和连续受力框架，克服了装配式节点受力可靠性差的缺陷，开辟了预应力结构工业化生产的新途径。 - Based on tests of three moment - resisting beam - column connections under low reversed cyclic loading , this paper inquires into the failure pattern , hysteresis loop curves , displacement - restoring capacity , displacement ductility and energy dissipation of the precast prestressed beam - to - column concrete connections with unbonded tendons
摘要通过三个框架节点在低周反复荷载下的试验，对无粘结预应力装配式混凝土框架连接的破坏形态、滞回曲线、变形恢复能力、位移延性、能量耗散等性能进行了研究。 - Subassemblage and prestressed concrete frames are assembled by precast prestressed beams and columns with tendons in the joints of the frames . these beams and columns are hoisted in site and the tendons are passed through the moire pipes . so prestressing force are brought to the joints of the frame . these tendons also can assume the moments at the end of the beams in ordinary condition
