抄録

In the previous paper, l have reported the method for the theoretical stress analysis on space trussed shells. This analytical method consists of taking out the small unite element which constitutes these space trussed shells themselves and setting up the equations of force equilibrium and compatibility to induce their fundamental differential equations. This present paper is concerned with the stress analysis of a hyperbolic parabolical space trussed shell which is simply supported on the boundaries, under normal uniform load. The calculation was derived by the application of finite difference method and its results are shown in Fig. (7), (8), (9), (10) and (11) which are compared with those of the hyperbolic parabolical space trussed shell which is supported with hinge edges, under the same condition. Furthermore, the experiment of full-sized hyperbolic parabolical space trussed shell was carried out and a comparative study of theoretical values of the stress analytical theory and the corresponding experimental values was reported. It will be useful for designing hyperbolic parabolical space trussed shell.
