EXACT SOLUTION FOR FINITE DEFORMATION PROBLEMS OF CANTILEVER BEAM WITH VARIABLE SECTION UNDER THE ACTION OF ARBITRARY TRANSVERSE LOADS

This paper deals with finite deformation problems of cantilever beam with variable sec- tion under the action of arbitrary transverse loads.By the use of a method of variable replacement, the nonlinear differential equation with varied coefficient for the problem can be transformed into an equation with variable separable.The exact solution can be obtained by the integration method. Some examples are given in the paper,and the results of these examples show that this exact solution includes the existing solutions in references as special cases.

组合式悬挑脚手架在高层建筑施工中的应用

结合苏州市工业园区一高层建筑施工实例,介绍了组合式悬挑脚手架的布置方案以及受力特点。设计时,利用有限元分析软件Midas和Abaqus对其型钢梁构件和锚支座分别进行受力分析,研究了跨度、悬挑长度、悬挑梁截面、拉杆水平角度等因素对悬挑式脚手架受力性能的影响。研究结论可供同类工程参考。
