| 摘 要： | 试验旨在研究箍筋约束对于混凝土轴压力学性能：强度、延性和随机性的影响.试验采用C70高强混凝土、方形箍筋约束试件,静态加载,每种试件得到5至7条全曲线样本.结果发现,当配箍率从1.1%提高到3.4%时,峰值强度提高47%,延性提高76%,同时标准差曲线峰值从8.95MPa降低到6.52Mpa,说明箍筋约束明显提升高强混凝土的力学性能,并减小其随机性.

| Abstract: | The experiment was conducted to help building hoop confined high -strength concrete model , and studying confinement effects on stochastics of concrete .The specimens were in size of 150＊150＊400, and used C70 concrete , square hoop , and loaded statically .The results show that hoop confinement can improve per-formance of high-strength concrete considerably , and reduce the randomness of stress -strain behavior as well . |
