摘要

摘要: 研究钢管高性能混凝土受弯构件中钢管和混凝土应力、应变等的分布规律。对钢管与混凝土相互作用力的研究表明,圆钢管对混凝土有很好的约束作用,方试件的相互作用力主要集中在弯角区域,平板区域的相互作用力很小。黏结强度对于试件的弯矩-曲率曲线基本没有影响。普通钢管混凝土受弯构件的承载力计算式同样适用于钢管高性能混凝土受弯构件的承载力计算。钢管高性能混凝土受弯构件与普通钢管混凝土受弯构件在静力性能方面并无本质区别。

Abstract: Distributions of stresses and strains of steel tube and concrete for high-performance concrete filled steel tubular flexural members were investigated.Study on interaction forces between steel tube and concrete indicated that the circular steel tube could provide better confinement than the square steel tube,while the interaction forces located at corners were the biggest ones for the square specimens.Adhesive strength had little influence on the moment-curvature curves of the specimens.Calculation formula of load bearing capacity for the normal concrete filled steel tubular flexural member is also suitable for the high-performance concrete filled steel tubular flexural members.There are no essential differences between the high-performance concrete filled steel tubular flexural members and the normal concrete filled steel tubular flexural members in aspect of static performance.
