简支梁端部上部构造钢筋设置问题的探讨

On Setting up Problems for the Upper Construction Reinforcement of the Simple Supported Beam

工程设计人员依据各类设计规范进行工程设计是一个工程师必须具备的职业素养,但也不能依赖性过高。根据《混凝土结构设计规范》(GB50010——2010)中第9.2.6条的规定,结合工程实际算例与规范规定进行比较分析,当梁跨及梁承受的荷载较小时,规范第9.2.6条所配置的梁支座区上部负筋偏小,而当梁跨及梁承受的荷载较大时,规范第9.2.6条所配置的梁支座区上部负筋偏大。因此,工程设计人员要从理论上掌握规范条文的实质内涵,果断地创新,使原有的设计规范得到进一步的修改完善。

On most occasions engineering design should be done according to the relevant regulations and rules,which is a professional quality that engineers must possess,but can not be depended on excessively.This paper made a contrastive comparison between practical engineering and specifications in the article 9.2.6 in Code for Design of Concrete Structures（GB51110-2010）.Results showed that when the load of the girder span and the girder itself was small,the negative reinforcement in the upper beam support area became small and vice versa.Hence engineering designers must have a good command of the regulation connotation in terms of theory,made decisive innovations so that the original regulations would be further perfected.
