【Abstract】 Researchers pay close attention to whether a circle beam should be added on the foot of column calculation of axial critical stress by using limited_unit and simple formula,which are consistent so that we can take use of simple formula to calculate axial critical stress quicklty.The results show that the design of geometry parameters(radium,wallthick) of furnace shell are reasonability,and the stability is enough.It need not add the circle beam.It provedes the base of reasonable design to the same kind of the furnace shell and it lays down an important foundation for rules of construct design to furnace shell.更多还原
