摘要
基于《建筑结构设计统一标准》(GBJ6 8- 84) ,应用结构可靠度分析的一次二阶矩法 ,分别对《钢 -混凝土组合结构设计规程》(DL - 5 0 85 /T - 1 999)和《战时军港抢修早强型钢 -混凝土组合结构设计规程》(GBJ- 2 0 0 0 )中有关圆钢管混凝土和方钢管混凝土轴压、纯弯及压弯构件的承载力设计公式进行了可靠度分析 ,分析结果表明 ,规程中设计公式基本满足统一标准对塑性材料可靠度指标的要求。
The second moment of first order method recommended in the National Design Standard of Building Structures (GBJ68-84)is applied to analyze the reliability of design formulae of compressing, pure bending and compression bending members,these formulae are recommended in Design Code of Steel Concrete Composite Structures( DL-5085/T-1999)and Design Code of Early Strength Steel Concrete Composite Strctures for Rush Repair of Military Port at War Time (GJB-2000).The analytical results indicate that the reliability indexes of the design formulae satisfy the demand of the National Design Standard of Building Structures( GBJ68-84)for plastic material on the whole.
