Abstract: Using the refererence [3],this paper proposed the formulae for calculation of the effective width of flanges in continuous tee-beam, and supplemented the data of effective width ratios to the table in the Handbook, edited by F. S. Merritt, Based on this, the suggestions for revision of the provision concerned in the draft of our "Highway Bridge Code for Design" are made。The recommended provision in this paper has advantage of simplicity in calculation, broad range of application and accordance with the actual mechanical situation。
