摘要
研究了配置HRB500级非预应力高强钢筋的无粘结部分预应力混凝土梁(UPPC梁)疲劳荷载作用下的挠度计算方法,根据试验结果提出了新的残余挠度与疲劳荷载作用挠度(瞬时挠度)的计算公式.计算结果与试验结果吻合较好.
The paper studies deflection calculation method of unbounded partially prestressed concrete beams（UPPC Beams） with HRB500 non-prestressed high-strength bars under fatigue loading.According to the test results,the new formula for residual deflection and deflection（instantaneous deflection） under fatigue loading is proposed.The results computed by the formula are in good agreement with the test results.
