摘要
在预制后张法预应力工字梁过程中 ,由于工字梁长宽比较大 ,各工序累计形成施工偏差 ,很容易造成工字梁张拉后横向弯曲 (又称“偏拉”)。
In the process of precasting the post-tensioned reinforced concrete I-shaped beams, it is easy to enable the I-shaped beams to eccentric tension due to the large ratio of length to wide deflection of precast post-tensioned beams, the deflection error have been accumulative formed in all procedure. This article analyzes the causes of eccentric tension and gives the measures for preventing and controlling the eccentric tension.
