(中交第三航务工程勘察设计院有限公司,上海 200032)[摘要]在高烈度地震区,相邻框架梁跨度相差过大时,可以将短跨框架梁按照连梁设计。通过工程实例,分析了将短跨框架梁按照连梁设计的准确性和可行性,并指出了设计时应注意的事项。[关键词]短跨框架梁;连梁;地震作用;跨高比中图分类号:TU375.4文献标识码:A文章编号:1002-848X(2011)08-0040-04Discussion on short-span frame beam design in high seismic intensity zoneZhou Rui(CCCC Third Harbor Consultants Co., Ltd., Shanghai 200032, China)Abstract:In high seismic intensity zone, when the spans of adjacent frame beams have great difference,the short-span frame beam can be designed as coupling beam. Based on an engineering example, the accuracy and feasibility of designing short-span frame beam as coupling beam were analyzed, and the problems should be paid attention to in design were preasented.Keywords:short-span frame beam; coupling beam; earthquake action; span-depth ratio作者简介:周瑞,一级注册结构工程师,Email:zhour@theidi.com。参考文献[1]GB50011—2010建筑抗震设计规范[S]. 北京:中国建筑工业出版社,2010.[2]JGJ3—2002高层建筑混凝土结构技术规程[S]. 北京:中国建筑工业出版社,2002.[3]GB50010—2010混凝土结构设计规范[S]. 北京:中国建筑工业出版社,2011.[4]方鄂华. 高层建筑钢筋混凝土结构概念设计[M]. 北京:机械工业出版社,2004.[5]黄小坤. 剪力墙连梁纵向钢筋构造配筋率探讨[J]. 建筑结构,2004,34(1):43-44,55.
