摘要
本文研究了混凝土强度为 ( 54～ 1 1 6) MPa的钢管高强混凝土的一些基本力学性能。研究结果表明 ,该强度范围内的混凝土经钢管约束后 ,强度大幅度提高 ,延性大幅度改善 ,强度提高的幅度与套箍指标 Φ 成正比。在此强度范围内 。
The mechanical properties of steel tubular High Strength Concrete with compressive strength of 54 to 116MPa are studied. The test results show that the steel tube confinement can significantly improve the ductility and compressive strength of core concrete. The increasing of strength is directly proportional to the Confinement Index Φ. No significant difference was found in strengthening cffect confined by steel between different concretes with different compressive strengths.
