摘要
根据试验结果介绍了预加应力不足梁下挠开裂后的力学特性。内容包括加载和卸载时的力学特性 ,缩短跨径对挠度和裂纹宽度的影响 ,同时对试验结果进行了分析。
Based on experimental results,the mechanical characters of the deflected and cracked concrete beam with insufficient prestressing are introduced,including the characters of the beams when the beams are loaded or unloaded and when its span is shortened.This paper can be for reference for reinforcing of similar prestressed beams.
