基于 MATLAB 拟合分析法的门式刚架轻型钢结构厂房最优柱距研究

摘要

本文拟利用 MATLAB 曲线拟合功能，针对用钢量与柱距的变化规律进行拟合分析，建立用钢量与柱距的关系方程式，再通过数学求极值点的方法求得最优柱距。本研究方法消除了用钢量计算数据的离散性对寻找最优柱距的影响，使求得的最优柱距结果具体明确，对工程设计具有一定的指导意义。%The paper makes use of MATLAB Curve fitting function, analyzes the law of steel quantity changing with column spacing, creates correlative equation of steel quantity changing with column spacing, next by mathematical method of seeking extreme points obtained optimal spacing. Research methods in this paper eliminate impact that the discrete of calculations to find the optimal spacing, obtain specific and clear results of the optimal spacing, so this may can guide the engineering design.
