现浇混凝土简支异形板最优配筋方法研究尚仁杰,李俊安,吴转琴,周建锋(中冶集团建筑研究总院结构所,北京 100088)[摘要]根据乔汉生屈服准则,得到了板内任一点既满足承载力同时又满足两方向配筋和最小配筋的计算方法。根据一点的最优配筋方法统一考虑一块板,得到了整块板内x向和y向统一配筋时两个方向最优配筋的上、下限值。给出了利用ANSYS在最优配筋的上、下限值范围内寻找整块板最优配筋的计算方法。通过工程实例介绍了对异形板进行最优配筋计算的分析方法和计算过程。[关键词]异形板;屈服准则;有限元法;配筋中图分类号:TU375.2文献标识码:A文章编号:1002-848X(2011)01-0068-03Study on the method to calculate the best reinforcement of the simple-supported irregular slabShang Renjie, Li Jun′an, Wu Zhuanqin, Zhou Jianfeng(Central Research Institute of Building and Construction, MCC Group, Beijing 100088, China)Abstract:The method to calculate the best reinforcement of one point was obtained, according to the Johansen yield criterion. The low and up bounds of the reinforcement of x and y directions of the whole slab were obtained based on the method of one point. ANSYS software was used to find the best reinforcement of the whole slab within the low and up bounds. The analysis and calculating method to find the best reinforcement of an irregular slab was introduced through an engineering example.Keywords:irregular slab; yield criterion; FEM; reinforcement作者简介:尚仁杰,博士,教授级高工,Email:shangrj2000@yahoo.com.cn。参考文献[1]派克 R,根勃尔 W L.钢筋混凝土板[M].黄国桢,成源华,译.上海:同济大学出版社,1992.[2]邵永健.钢筋混凝土异形板的极限分析[J].苏州城建环保学院学报,1999,12(1):44-48.[3]童岳生,钱国芳,吴豹.钢筋混凝土异形板的试验研究[J].土木工程学报,1993,26(4):61-68.[4]高秀华.求解异形板弯曲的康托洛维奇法[J].山东建筑工程学院学报,1998,13(2):72-76.[5]童岳生,童申家,钱国芳.钢筋混凝土L形板的试验研究和极限分析[J].西安建筑科技大学学报,1997,29(4):368-372.[6]苏小卒,季建平,韦玉华.直角三角形钢筋砼板的计算用表[J].特种结构,2000,17(1):15-19.
