| 摘 要： | 对国内外体外预应力混凝土梁挠度的计算方法进行了总结与分析 ,已有计算方法考虑预应力增量及二次影响仅限于短期挠度计算。进一步的分析表明 ,体外预应力受弯构件挠度计算还需要考虑材料的非线性、混凝土收缩和徐变、高温等因素及各因素之间的相互影响

| Abstract: | The deflection calculation methods of externally prestressed concrete beam both home and abroad are reviewed.The existing methods have considered tendon stress increase and second\|order effect,but limited to short\|term deflection calculation.Further analysis indicate that other factors such as material non\|linear,concrete shrinkage and creep,high temperature performance,as well as the interaction among these factors,should also be considered. |
