THE DESIGN AND ANALYSIS OF ONE SINGLE LAYER CYLINDRICAL LATTICE SHELL OF HUANENG BUILDING

By an example of analyse and design of one single layer cylindrical lattice shell with low rise-span ratio,mechanical characteristic of the shell was analyzed;the effect of support stiffness on the shell was discussed;the method of structure of shell joint and design of shell were introduced;especially the global stability was studied.It was concluded that single layer cylindrical lattice shell with low rise-span ratio was sensitive to stiffness of support and initial geometrical imperfections;and if plastic is considered,the critical load of the shell will be reduced greatly by contrast with elastic critical load;stiffness of support has different effect on the shell in different load cases.
