In succession to the examinations reported in Part II, the former half of the current presentation is devoted to completing the second phase of this study where the dynamics of typical constituent elements has been a matter of particular interest. The remaining problems arise from practically important combinations of the fundamental types of A, B and C; two hybrid cases of Models (C+A) and (B+A) are taken up according to the application of constant-Q material damping assumption to the rational impedances for rocking and swaying of a surface footing. Following a set of general theories developed in Part I, their dynamic properties are clarified with regard to the same points as in the preceding discussions of Models A and C. More serious appearence of the singularities involved in Model A features the results obtained in these examinations. The third phase of this study is an investigation of the dynamics of overall systems represented by the total combination of Models A, B and C which are applied segmentally. Along the foregoing lines of reasoning, formulation of building-foundation-soil interaction is the first concern therein. Then example analyses are done by use of a bare-minimum reduction of superstructure, with a view to identifying the basic mathematical structure in their nonelementary response behaviour. The latter half of this presentation is intended to provide preliminary remarks for the subsequent discussions of the third phase. This is primarily concerned with the aspect of formulation, and includes reference data on the transfer-function relationships in frequency domain.

The purpose of present study is to develope a new beam-column model based on modified complementary energy principle, considering the validity of the force method for the problem of material non-linearity. As its first report, a new plane beam-column model for elasto-plastic and collapse analysis is proposed in this paper. This model satisfies completely both equilibrium and compatibility conditions for any states of stiffness distribution and load, namely has no discretizing error. Therefore, if the evaluation of stiffness and energy integration are accurately carried out, the exact solutions can be gained in every range. Also, application of the plastic hinge method to this modelcan be simply put in operation by the Lagrange multiplier. A series of analysis have duly proved that this model might be very powerful for the problem of material nonlinearity.

2次元正四角柱に作用する風圧変動に関する風洞実験から, 風上面に作用する風圧変動の特性の迎角による変化に関して, 次の諸点が明らかとなった。(1)角柱の停流点に作用する風圧変動のパワースペクトルは, 迎角の影響をほとんどうけない。(2)停流点以外の風上面の各点に作用する風圧変動のパワースペクトルは, 迎角が増大するにつれて, 停流点より風上側では変動のパワーが増大し, 風下側では変動のパワーが減少する。この傾向は特に低周波数領域で著じるしい。(3)風圧変動のパワースペクトルは, 周波数が小さくなるにつれて, 停流点より風下側ではしだいに準静的理論値に近づくが, 停流点より風上側では実験値の方が理論値よりもかなり大きくなる。これは, 準定常理論値を求める時, 風向方向と風向直角方向の風速変動の相互相関を零と仮定したことに起因すると考えられる。(4)角柱の中央線に沿っての軸方向の風圧変動のスケールは, 迎角の増大に伴って大きくなる。スケールの増大する割合は, 一般流の乱れのスケールに関係があり, 乱れのスケールに対する角柱の大きさの比が大きい程, 風圧変動のスケールの増大率は著じるしい。(5)角柱の風上面に作用する風圧変動の特性は, 停流点から風下へと移動する。風圧変動の移動速度は, 迎角0°の場合が最も大きく一般流の流速の約1.7倍で, 迎角の増大に伴って減少する。迎角20°以降は, 移動速度はほぼ一定となり, 一般流の流速とほぼ等しい。(6)風の乱れによる建物のねじり振動の大きさは, 曲げ振動の約5割に達する。壁面に沿う風圧変動の移動は, このねじり振動を1割程度増大させる。

The purpose of this study is to trace quantitatively the stress distribution and deformation characteristics of the column base connections by using "Theory of Beams" & "Finite Element Method" on elastic foundations, and is to compare their analytical values with the experimental results and discuss. This paper reports an outline of their experiments and analyses. The main results derived from these investigations are as following : (1) The analytical values of the rising amount of the base plate are in good accordances comparatively with the experimental results in either case, but the analytical values of the sinking amount of the base plate in compression side are slightly greater than the experimental results. (2) In the estimate of a degree of fixity in column bases, it may be considered that the relations between M/P and φ/P are presented nearly by the Bi-Linear type which is changed the slope at the point of the eccentricity to occur first the tensile stress in anchor bolts.

Elastic-plastic ultimate strengthes of gable typed rigid frames were examined against the symmetrically distributed vertical loads using the elastic-plastic buckling analysis method. As the result of parametric study about various gable typed frames, we obtained the criterion of necessary slenderness ratio of frames to prevent the elastic-plastic asymmetrical buckling preceding the mechanism by simple plastic theory.

The present paper follows the author's preceding two papers on axisymmetric static, dynamic and astatic buckling of clamped spherical caps due to a uniform step load. The analysis is based on the finite element method and mode superposition method. This method avoids the direct finite element methods of nonlinear effects and also takes an advantage of the importance that a structural response is fundamentally due to several basic vibration modes. The in-plane displacements which satisfy the tangential equilibrium equations are obtained compatible with the normal displacements which are, alone, assumed by eigen vectors. The governing equation is composed of a set of algebraic cubic polynominal equations in terms of the generalized displacements. The coefficients in the equations for a shell with an initial imperfection are obtained through a simple manupilation of those for the perfect shell and the coefficient in Fourier expansion of the imperfection. The conclusions from the present analysis are as follows. (a) The dynamic buckling load is severely reduced by asymmetric imperfections, reaching to one-fifth of the classical static buckling load in case of λ=7 and ω_i/t=0.30. (b) Asymmetric imperfections have the same effects as the symmetric imperfections if the magnitude ω_i/t is greater than around 0.2. (c) The dynamic buckling mechanism is classified approximately into three types. (1) Direct snap through buckling. (2) Bifurcating dynamic buckling into asymmetric deformation, with a complete snap through to a reversed shape. (3) Bifurcating dynamic buckling into asymmetric deformation without snapping to a reversed shape.

How to estimate the complex configuration is an important problem on the investigation of dynamic properties of a soil layer composed of composite media. The complex configuration of composite media is spatially averaged in the domain of the media in order to idealize the media. Three method of averaging have been proposed up to date. Especially in the equivalent mixture method, dynamic properties of the complex configuration are obtained analytically with relative ease. Namely it is possible to represent composite media by mixture media. But composite media with the complex configuration are not replaced by mixture media. In this paper, the replacement of composite media by mixture media is studied, and the representation of the wave propagation in the soil layer composed of composite media is given. A procedure of this research is as follows. The fundamental equation of the field problem of monophase media and multi-phase media is represented briefly in Chapter 2 and 3. A new method is proposed by combining Finite Element Method with the composite mechanics in Chapter 4 and 5. The phenomenon of the wave propagation is described for a soil layer such as an alternated layer and a pile reinforced ground, in the latter half of Chapter 5. In Chaper 6, the dispersion relation for composite media is used as the constitutive relation when frequency responses are analysed. Composite media herein are composed of two phase materials which are of homogeneous, isotropic and linearly elastic.

This paper reports studies on Design proper, not for Design. We study for about 10 years, on the framework and the method of Design through the Design Process and System. We show the range of Design we study, and the differece between our study and other studies on Architectural Design in Japan. We discuss on Architecture and Man as users, clients, designers, maintain-ers and so on. From the point of view of a Designer we distinguish Design in a narrow sense from Design in a wide sense. And studies of Design in a narrow sense is situated onground of researches on Architectural Design. From our point of view of Design, we regard the Design Science as the Science of the Artifitial, not Natural Science. And we show our consciousness of the problem, aim, the range, the approach, the method, form of output and input, and development of our study. Finally, with a view to getting aid to gain better Design results by programming Design better, we study Design, especially its mechanism and Design Method to gain better results. Our aim and end is to lead to the theory and technics of the Design Programming.

Residential districts composed mainly of detached houses are one of dominant features in Japanese urban area. Environmental quality for living in these districts is changeable toward the worse in a long time. This is caused by arbitrary building activity of each dwelling unit. Nevertheless we have only insufficient control system to maintain or improve residential quality in these districts. So it is urgent need for us to establish the general control system which deals with these problems. In this study I propose a new control method of land use intensity for these districts. The method uses Lot Utilization Distribution Curve (L. U. D. C.) which is derived from upper and lower numerical level of utilization area for residential dwelling in the region. These levels are determined statistically according to distribution pattern between utilization area and lot area or artificially according to the purpose of its control. L. U. D. C. is applied to urban districts in Kanazawa in this study and those are evaluated as follows. L. U. D. C. is useful as an analytical method because we can grasp main characters of each district and evaluate the effectiveness of the current control level of land use intensity over there by using it. Also L. U. D. C. has possibility to be used for control method of land use intensity. In that case we can know lot area according to control level or control level according to planned lot area through L. U. D. C.. These numerical levels could be used important criteria for control planning of land use intensity.
