The experiments showed that the cracking process of such restrained beams in this paper can be divided into three phases , that is , formation of the fanning zones , initialization and development of splitting cracks along longitudinal reinforcement , and accelerating development of the critical crack and / or cracks ( diagonal , flexural ) . during the last two phases , it was observed that further opening of some cracks led to some
研究结果表明，钢筋混凝土有腹筋约束梁的裂缝开展过程大致可分为扇形区逐步形成、劈裂裂缝出现和发展、最终临界裂缝（斜裂缝或弯曲裂缝）加速发展至破坏等阶段。在后两个阶段中存在某些裂缝发展减弱同时某些裂缝迅速开展的“此消彼涨”的现象。
