摘要
根据文献中数学规划优化算法,充分考虑钢结构建筑特点,以用钢量最低为目标函数,结合实际工程建立了钢结构全约束优化设计数学模型,给出了多层建筑钢结构复合形法优化算法公式并编制相应的优化设计程序。结果表明,此算法能优化结构、节约钢材、降低工程造价,对工程设计有较强的参考价值,具有很好的直接实用性。
According to the mathematical programming optimization algorithm in the literature,considering the features of steel structure building and taking steel weight as objective function,binding the practice the paper establishes optimal design mathematical model which includes the whole constraint and achieves the complex method optimization algorithm formula of multiple-story steel buildings and the corresponding optimal design procedure. The results of case analysis show that we can optimize structure and reduce weight and cost of steel structure by using this method presented in the paper and the method has good referenced value for engineering design and practicality.
