| 摘 要： | 基于黏结滑移理论对适用于型钢混凝土结构的高强高性能混凝土进行了配合比优化设计,考虑到混凝土性能与各种原材料之间并非简单的线性关系,以型钢与混凝土的协同工作能力和混凝土的单方成本为目标函数,混凝土的其他性能指标为约束条件建立了非线性约束的多目标优化设计数学模型,基于序列二次规划法通过Matlab语言实现了该模型的求解,并进行了优化前后对比分析,优化后的混凝土能够满足所需要的各项性能,而且其与型钢的协同工作能力和经济效益有较大的提高.

| Abstract: | For designing high strength and high performance concrete(HSHPC) applied to steel reinforced concrete(SRC) structures,a multi-objective and nonlinear optimal mathematic model is established based on the bond-slip theory between steel shape and concrete,which takes the materials' cost and bond strength as objective functions,and takes the other performance indexes of HSHPC as constraint conditions.Optimal mix design is implemented with an application of Matlab language by calling its sequential programming.A... |
