工业建筑厚板结构设计及分析方法的探讨

Design and analysis of slab in industrial architecture

厚板结构是工业建筑中常用的结构形式之一,通常工程上将其简化为梁柱体系的框架结构,并采用TA T等程序对其进行结构内力和位移计算.该方法虽简单实用,但不能准确反映厚板和角柱受力状态.针对这一问题,采用A L G O R FE A S有限元分析程序,将其划分为三维块单元,模拟实际荷载,对其进行结构分析,并和TA T程序计算结果进行比较,得出结论:TA T等程序将此类厚板简化为梁柱体系的框架结构的分析方法,厚板的设计偏于安全,而角柱的角点应力无法计算;按A LG O R FE A S程序计算的厚板的剪应力,角柱拉应力及压应力均较大,采用TA T等程序简化设计时,尚应加强角柱配筋和厚板抗扭配筋.

Slab is one of the general structures in industrial architecture. Normally,it is predigested to frame of beam &column system firstly and analysed on inner force and displacement with TAT and so on programs. Although this is a simple and practical method,but it still has insufficiency. To this point,the paper divided it into 3D elements and simulated actual loads to calculate its inner force and displacement with ALGOR FEAS program,and compared the result with that of TAT program. Conclusion is the analysis method that slab is predigested to frame of beam &column system analysed with TAT can put mechanical state of slab besides corner column,however,shear stress of slab and tensile stress and compressive stress of corner column are stronger to enhance the bar arrangement of corner column and of the slab.
