【摘要】：钢管混凝土柱大量应用于工业厂房中,针对宝钢冶金厂房在使用过程中存在的问题,在改进型钢管混凝土柱单腹板肩梁承载力试验的研究基础上,对肩梁的高厚比与高跨比进行有限元参数分析,得到其对整体结构承载力的影响规律.根据试验及有限元分析结果,对钢管混凝土柱肩梁承载力设计方法进行研究发现:按考虑剪力作用下腹板受剪破坏控制方法进行设计较符合实际情况,并给出实用计算公式.通过与有限元计算结果比较得出:肩梁承载力实用公式满足结构可靠度规定的要求.研究将对该新型肩梁的工程应用奠定一定的基础.
[Abstract]:Concrete-filled steel tubular columns are widely used in industrial buildings. In view of the problems existing in the process of use of Baosteel metallurgical buildings, the bearing capacity of the improved concrete filled steel tubular columns with single web shoulder beam is studied. The finite element parameter analysis of the ratio of height to thickness and the ratio of height to span of shoulder beam is carried out, and the law of its influence on the bearing capacity of the whole structure is obtained. According to the results of experiment and finite element analysis, the design method of bearing capacity of concrete-filled steel tubular column shoulder beam is studied. It is found that the design method based on the shear failure control method of web plate under the consideration of shear force is in line with the actual situation, and the practical calculation formula is given. By comparing with the results of finite element calculation, it is concluded that the practical formula of bearing capacity of shoulder beam can meet the requirements of structural reliability. The research will lay a foundation for the engineering application of the new shoulder beam.
