The authors provides a new method named limitation coefficient of tension stress method , which can calculate the quantity of prestressed tendons , taking the prestressing secondary moment into account 本文提出了計(jì)算預(yù)應(yīng)力筋數(shù)量的“拉應(yīng)力限制系數(shù)法”這一概念,并由之推導(dǎo)了考慮預(yù)應(yīng)力次彎矩的計(jì)算公式。
And two types of fatigue equations are put forward . according to them the fatigue stress coefficient of lcb for the concrete pavement structure and the structure coefficient of tension strength of lcb for the asphalt pavement structure are developed 并提出了貧混凝土兩種形式的疲勞方程,據(jù)此推導(dǎo)了混凝土路面結(jié)構(gòu)貧混凝土基層的疲勞應(yīng)力系數(shù)和瀝青路面結(jié)構(gòu)貧混凝土基層的抗彎拉強(qiáng)度結(jié)構(gòu)系數(shù)。
