Abstract: Based on discussing the method of calculating cylinder pier′s crack width under eccentric load in the new Specifications for Design of Reinforced Concrete′s and Prestressed Concrete′s Highway Bridge and Culverts,and the method of using traditional nominal tension stress to calculating it indirectly, we have first brought forth a new simplified method to calculate cylinder pier′s crack width directly by using nominal tension stress, and then verified the data frequently used in engineering. The p

Key words: cylinder pier, eccentric load, crack width, nominal tension stress, multiple regression analysis

摘要： 笔者讨论了新5公桥规6中偏载作用下圆截面墩柱裂缝宽度的计算方法，以及传统的用名义拉应力法间接控 制裂缝的方法，提出了用名义拉应力直接计算其裂缝宽度的简化计算方法，并对工程中常用的数组数据进行比较 验算证明，该计算方法极大地简化了计算程序，并与按新5公桥规6计算的结果吻合较好
