摘　　要：钢筋的锚固、搭建、弯起及截断混凝土结构中,对钢筋的构造要符合结构受力整体效果的要求,实现内力的传递及其运行,保证工作能正常运行,但考虑到问题的复杂性、各国在混凝土受力及计算方式等规范的影响因素不同,从而对钢筋构造做出的规定也就产生不同,不同的规范处理可得到不同的结果。在钢筋混凝土的结构构建中,混凝土钢筋在锚固长度及绑扎搭接接头的结合区域很有可能产生开裂的情况,前者开裂的情况即锚固裂缝,后者则称作连接裂缝。The reinforcement structure,reinforcement,and truncated concrete structure of the steel bar are required to meet the requirements of the structural force as a whole.The internal force transmission and its operation are carried out to ensure the normal operation.However,taking into account the complexity of the problem,countries in the concrete force and calculation methods such as the impact of different factors,so the provisions of the steel structure will be different,different regulatory treatment can get different results.In the construction of reinforced concrete,the concrete reinforcement is likely to crack in the anchorage length and the bound area of the lap joint.The former is called an anchor crack,and the latter is called a joint crack.
