摘要

摘要: 为配合辽宁省地方标准《钢管混凝土结构技术规程》的编制,对钢管高性能混凝土压弯构件中钢管和混凝土应力、应变等的分布规律展开研究。对钢管与混凝土相互作用力的研究表明,圆试件受压区的约束力较大,方试件钢管角部区域的相互作用力最大。所有试件中截面受压区的相互作用力最大。黏结强度和加载路径对钢管高性能混凝土压弯构件的静力性能影响都不大。普通钢管混凝土压弯构件的承载力计算式同样适用于钢管高性能混凝土压弯构件的承载力计算。钢管高性能混凝土压弯构件与普通钢管混凝土压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 beam-column were investigated.Study on interaction forces between steel tube and concrete indicated that confinement force located at compressive region was bigger than other locations for circular specimens,while the interaction force located at corners were the biggest ones for the square specimens.All of the specimens had the biggest interaction forces on the compressive region at the mid-height cross-section.Adhesive strength and loading path had little influence on the static performances of the specimens.Calculation formula of load bearing capacity for the normal concrete filled steel tubular beam-column is also suitable for the high-performance concrete filled steel tubular beam-columns.There are no essential differences between the high-performance concrete filled steel tubular beam-columns and the normal concrete filled steel tubular beam-columns in aspect of static performance.
