This paper shows a method of member proportioning for cylindrical latticed roofs subjected to several loads. Also this paper investigates elastic plastic buckling strength of members for cylindrical latticed roofs designed based on the present method. Firstly, this paper describes briefly the method of member proportioning. Secondly, maximum load of cylindrical latticed roofs of which members designed based on the present method is investigated. Also the elastic plastic buckling strength of members for the latticed roofs is investigated. Finally, the effectiveness of the present method is discussed based on above investigations.
