T型梁是工程中常用的受弯构件。通过控制变量法对T型梁截面的翼缘宽度、腹板宽度、翼缘厚度和腹板高度这4个尺寸参数进行逐一分析，研究加大每个参数对抗弯刚度提升的贡献程度以及对工程造价的影响，得出在设计中需要提高梁的抗弯能力时应适当增加腹板高度来达到经济合理的要求，降低工程造价。%T beam is commonly used as bending member in engineering. Using the control variable method,the dimensional parameters flange width,web width,flange thickness and web height of T beam section are analyzed one by one. The contribution degree of increasing each parameter on the improvement of bending stiffness and the influence on the engineering cost are researched,and it comes to a conclusion that we need to improve web height when it is necessary to increase the bending capacity of beam in the design for economic and reasonable requirements,and reducing the cost of project.
