Research Abstract

The present study has the potential purpose of the application of pultruded fiber reinforced polymer (FRP) shapes to various kinds of large span roof structures, therefore, the rigid jointed single layer latticed cylindrical roof structures have been treated here. First of all, the experimental identification of the stiffness components of the FRP shapes and the linear stress analysis using finite beam elements have been carried out ; the displacement are shown not to increase in proportion to the material consistencies in respect to the steel structures. Second, the undamped free vibration analysis was performed, and it has been shown that the eigen frequencies and modes are varied not with the stiffness but the whole structural dimension. Third, the seismic response analysis was carried out, and it has been suggested that the stress level of longitudinal direction members is very low, however, the diagonal direction members suffer from the relatively large stress through dynamic earthquake response vibration. Finally, it would be shown that the vibration mode, stress distribution, moment resultants, dynamic stress behavior of the FRP large span structures are very similar to those which consist of steel members.
