Large span roof shell structures have an inherent tendency to be unstable under dynamic loads. However the dynamic behavior of these is not well documented. An in depth analysis is required to understand its bending, vibration, axial, buckling etc. However, the present investigation focused on free vibration behavior. In this research study, models of spherical single layer reticulated roof shell structures were established in Finite Element software CSi SAP2000. Based on free vibration frequency the dynamic behavior of these structures was investigated in this research paper. Parametric analysis was conducted and the influence of these parameters on the structure was observed in terms of free vibration frequency. Several parameters were considered for the analysis such as, different span diameters, different roof loading and rise to span ratios. Based on the analysis, the optimum rise to span ratio was found out.
