摘要
根据《公路钢筋混凝土及预应力混凝土桥涵设计规范》,利用Midas建立梁单元模型,分别取不同的混凝土徐变系数,计算了在施工过程中连续梁由混凝土徐变产生的挠度,并分析了连续梁在施工过程中徐变系数对挠度的影响。
According to the standard Code for Design of Highway Reinforced Concrete and Pestressed Concrete Bridges and Culverts, building beam dement by Midas, used different concrete creep coefficient, calculated the flexivity of continuous beam which created by concrete creep in construction process, analyzing the contribution of creep coefficient to flexivity.
