多层框架结构梁板构件的裂缝分析及加固处理

Fracture analysis and reinforcement of beam and slab member in multi-storey frame structure

通过对多层框架结构梁板构件常见裂缝的分布形式及机理分析,结合近年来结构裂缝防控和加固处理的一些实践经验,从裂缝加固处理的技术、材料、工艺和实用等方面进行了对照比较,提出了几点裂缝控制和加固的技术建议,为保证框架结构适用性和耐久性提供了理论依据和实践参考。

This paper puts forward some technical suggestion on crack control and reinforcement, through analysis on crack distribution and mechanism of beams and slabs in multistory frame structures, combining With practical experience of prevention and control and reinforcement treatment in structure crack,comparing with the technology,material, process and utihty recently. The research is intended to provide theoretical basis and practical reference on ensuring the apphcability and durability of frame structures.
