环境温湿度与组合梁频率变化的回归分析

在对户外一片两跨连续组合梁进行近一年的环境振动监测和分析的基础上，基于数理统计回归方法对环境温湿度与组合梁的频率进行线性和非线性回归分析， 建立三种回归模型，对比分析表明，运用考虑温度不均匀性情况的四元线性回归模型既可以使环境温湿度与频率得到较理想的回归效果又有良好的预测性，同时也具有普遍适用性。

Regression analysis of environmental temperature and humidity and the natural frequencies of composite beam

Abstract: According to environment vibration monitoring nearly a year and analysis of a piece of two span continuous composite beams, the paper builds three regression model basing on the mathematical statistics method of the environmental temperature and humidity and the combined beam frequency linear and nonlinear regression analysis. The comparative analysis indicates that the four element linear regression model considering the temperature uniformity can not only make the environment temperature and humidity and the frequency be more ideal regression effect and good prediction, but also has universal applicability.
