摘要
本文在对比国内外预应力混凝土裂缝控制规定的基础上,提出裂缝控制应与环境条件、荷载状态及非预应力普通钢筋的配置等主要因素相联系;并根据不同规范的计算结果,提出了改进抗裂设计方法的建议。
The paper presents that the crack control of prestressed concrete should take main factors,such as environmental conditions,loading states and arrangement of ordinary steel reinforcement,into account on the basis of the comparative study on provisions of crack control in Chinese and foreign codes Then the crack analysis of PC sections is dealt with by various designing codes and a suggestion on the improvement of crack design is made in the paper
