This study seeks to make clear the fundamental vibration behavior of rigidly jointed single layer latticed cylindrical roof structures having the constitutive members determined to be of an optimized cross-sectional area by using the reduced stiffness buckling concept. The present single layer latticed roofs are adopted as an equilateral triangle network pattern and pinned support system. A dynamic transient response analysis for damped up-and-down or horizontal motions is performed. The response behavior is shown to be much related to free vibration modes. The effects of the safety factor, the dead loading weight, the span and the cut-outs on the dynamic behaviors are discussed by using the result of a finite element analysis.
