This paper treats the buckling experiment of single layer two-way grid dome with PC bars as diagonal member s. PC bars are used to stiffen the in-plane rigidity of two way grid. The introducing initial axial force to PC bars, the central loading, and the asymmetrical loading are performed in order to investigate the effect of initial axial force of PC bars on the buckling behavior of single layer two-way grid domes. The specified value of initial axial force is introduced to PC bars. The rigidity and the buckling load of these domes are increased by the effect of the initial axial force of PC bars. Moreover, buckling behavior of experimental results is compared with the numerical results. The validity of the numeric al method used in this study is shown.
