由于温度和收缩应变的限制而导致的过度开裂是混凝土建筑行业中普遍存在的问题。在设计中,通过提供旨在以控制开裂模式和限制裂缝宽度的方式分布内部应变的钢筋来管理约束诱导裂缝。挡土墙和水箱等构件所需的二次(水平)钢筋面积通常由控制早期热开裂的需要决定。本文介绍了在伦敦帝国理工学院和利兹大学作为工程和物理科学研究理事会资助的约束诱导开裂项目的一部分进行试验的四个边缘约束墙的结果。本文描述了试验墙体的体积应变和开裂的发展。通过比较约束应变与混凝土的抗拉应变能力来评估其开裂性能。
Excessive cracking due to restraint of thermal and shrinkage strains is a widespread problem in the concrete construction industry. In design, restraint induced cracking is managed by the provision of reinforcement intended to distribute internal strains in such a way as to control the cracking pattern and limit crack widths. The area of secondary (horizontal) reinforcement required in members such as retaining walls and water tanks is often governed by the need to control early age thermal cracking. This paper presents results from four edge restrained walls tested at Imperial College London and the University of Leeds as part of an Engineering and Physical Sciences Research Council funded project into restraint induced cracking. The paper describes the development of volumetric strain and cracking in the tested walls. The cracking performance is assessed by comparing the restrained strain with the tensile strain capacity of concrete.
