摘　　要：根据《混凝土结构设计规范》,结合工程实例,对钢筋混凝土结构的大偏心受压构件受压钢筋出现负值时的情况进行探讨。通过对工程实例的分析,给设计人员提供了在设计中遇到类似情况时的处理方法根据构件的受力情况,充分利用混凝土的抗压强度,合理选择配筋形式,达到节约钢筋用量,降低工程造价。Based on Concrete Structure Designing Specifications and actual engineering instances, the situation of negative value occurred on the pressed reinforcing steel bar of large eccentricity pressed structure is discussed. By analyzing with the real engineering instances, a method that deal with the situation is obtained that will be of help to the designing engineers. Lesser consumption of reinforcing steel bar and lower engineering investment can be achieved by taking full advantages of press resistance of concrete and proper arrangement of the reinforcing steel bar based on the structure forcing situation.
