摘要
本文目的在于,通过仿真模拟,可就预应力的施加以及现场试验的加载制度等提出合理建议,可以在试验前预测构件在预应力筋张拉过程中应力、应变、挠度等的变化规律,为梁的预制加工和现场足尺试验提供指导。
For the aim of giving proper suggestions for the tension of tendons and its loading system before prodcing and field experiment of full-size beam, the simulation analytical method to get variation law of stress, strain and deflection in the curse of tensioning tendon are discussed in this paper.
