    Among the studies related to the hyperbolic paraboloidal shell, particulary, it is reported here on the correlation of bending analysis between the general hyperbolic paraboloidal shell (2Z=A^2・X^2-B^2・Y^2) and usual hyperbolic paraboloidal shell (Z=kξ_1ξ_2) and its mechanical characteristics. If both sides of the general hyperbolic paraboloidal shell are cut off by a oblique plane and a curved surface is. constructed in the central part, the hyperbolic paraboloidal shell is formed by the hyperbola around the shell and concave or convex parabola in the central part. Therefore, the deformation and the condition of stress-distribution of the shell depend upon the curvature of a concave or a convex curve, in othere words, the variations of antirise h_x and rise h_y. In the case of h_x=h_y and of the same span, the general hyperbolic paraboloidal shell and usual hyperbolic paraboloidal shell should form the same curved surface on the same coordinates. Accordingly, utilizing these characteristics, the relationships of bending solutions between both shells were made forecast. Besides, from the viewpoints of engineering, a full-sized structure was taken up as an example and the bending numerical analysis on the general hyperbolic paraboloidal shell was performed by calculus of finite difference under the limited condition and its mechanical characteristics were explained distinctly. Moreover, the relationships about the edge beam and the axial forces of tie beam and the deflection at the center of shell due to the restraint rate in the toe part of the shell were cleared up and then the behaviour of stress-distribution was discussed.

    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.

    In the previous investigation, it has been shown that strength of the joint decreased as a result of stress concentrations in flange portions of a square-section tube to which gusset plates were welded directly, loaded in their plane by tension forces on the ends. The results of series of tests on the joints reinforced with triangular stiffeners which are made of various sizes, or on the joints reinforced with seat angles which could be often seen up in present-day construction, are presented in this report to compare with each other's. By using the triangular stiffeners the strength in the joint was improved as a result of preventing the "Platten-like" deformations in flange portions of the tube. Therefore maximum load was ca. 1.5〜2.0 times as large as that of unstiffened. It is significant, however, that the maximum load was not increased, in the case of the joint reinforced with the angles, because under tension load weld cracks began at points of contact between the gusset plate and web of the tube at a lower load, and because under compression load the web portions buckled locally. A simple theory described give adequate explanation of experimental behaviors, i.e., the strength of the joints reinfouced with the stiffeners may be computed under the tension load only by resistance of the qusset plates, and under the compression load only by local buckling resistance in the web portions of the tube themselves.
