| Outline of Final Research Achievements |
Computer systems of structural analysis for spatial structures with irregular surface were developed based on the theories generating wind ripple, sand dune and riverbed. The structure from wind ripple and sand dune is generated by adding coordinates of the ripple to those of the dune. The part of dune is an approximation using sinusoidal wave with a half wave length. Analytical results show the effect of wind ripple form to the stiffness of the dune can be thought to be large. When comparing this structure with one constituted of two regular sinusoidal waves instead of them, the stress and displacement of the later became 30% less than those of the former.
As for the structure generated by a theory on the riverbed, the model with large fluctuation has a trend that the deflection and bending moment of the members decrease.
