摘要:
分析了预应力混凝土吊车梁存在的问题,并结合实际情况,对其提出了初步可行的处理方案。通过对初选方案的对比与优选,结合使用要求,确定采用黏贴碳纤维布(CFRP)方案对吊车梁实施加固。详细介绍了用碳纤维布加固鱼腹式T形截面预应力混凝土吊车梁的设计方案,给出了正截面受弯和斜截面受剪补强加固的计算方法,并提出了相应的施工方法及具体的构造措施。研究结果表明,加固处理后吊车梁的各项技术指标均达到了设计要求,效果良好。
Abstract:
The tentative treatment schemes were put forward to solve the existing problems in prestressed concrete crane girders. Through comparing and analyzing the initial treatment schemes, and combining the demands of use, the sticking carbon fiber reinforced polymer(CFRP)was chosen to strengthen crane girders. Authors introduced the design schemes to strengthen fish-bellied T-section prestressed concrete crane girders by CFRP, including the computing methods of bending and shear carrying capacity, as well as the corresponding construction methods and strengthening measures were presented. The research result shows that all kinds of technical indexes of crane girder can meet the demands of design after strengthening.
