Tests on laterally unbraced H-shaped beam-columns were conducted to study the lateral torsional buckling strength and deformation behavior in the inelastic range. Beam-columns were subjected to constant axial compression and gradually applied end moments about strong axis of cross section. Main findings obtained from test results are as following : 1. Members with relatively large slenderness ratio collapse immediately after buckling initiates. Tangent modulus loads well correspond to ultimate strength of such members. 2. Members with relatively small slenderness ratio have a considerable post-buckling strength and failure is caused by the combination of lateral torsional buckling and local buckling of the compression flange. Tangent modulus loads are not reliable indices of ultimate strength of such members. 3. Most of specimens collapse suddenly after maximum bending moment in the member reaches a certain value. Thus the maximum bending moment may be taken for an index of failure of the members.

ON APPLICABILITY OF MULTI-PHASE THEORY OF THE AGGREGATE BODY ON A WATER-SATURATED SANDY SOIL GROUND

In this paper is investigated the applicability of the multi-phase theory of the aggregate body on a water-saturated sandy soil ground, referring to numerical results on the wave propagation problem of body or Rayleigh waves and the evaluation of the dynamical Poisson's ratio or other physical parameters. According to this investigation, the phase velocity of the first kind dilatational wave almost coinsides with that of water wave in soft soil ground. On the other hand, the phase velocity of the second kind dilatational wave is smaller than that of the first kind wave. The attenuation coefficients of the second kind wave is much larger than that of the first kind wave. The velocity of the rotational wave is nearly equal to the travelling velocity of the porous elastic solid under consideration of the mass effect of the pore water. In some parameter range, two kinds of Rayleigh waves exist in the aggregate body under a pervious or impervious free boundary. In general, the first kind Rayleigh wave exists in it, but the second kind Rayleigh wave disappears and changes in the second kind dilatational wave in the case of the large value of Poisson's ratio. Even in the case of the small value of shear rigidity, the computed value of the dynamical Poisson's ratiois nearly equal to be 0.5. It is, in essential, necessary to use the soil aggregate model under the multi-phase theory for the existence of two second kind dilatational and Rayleigh waves with high attenuation propperty, because such soil aggregate model is able to make clear the radiation damping together with the internal dissipation energy of these second kind waves in a soil-structure interaction problem.

The ultimate strength of the beam on the elasto plastic foundation, e.g. on the soil bed, is not yet clarified, but it seems to be quite necessary to investigate the collapse load of such beam to obtain the reasonable factor of safety in practical design. To pursue the process of fracture of a beam laid on the soil bed, it will previously be required to know the properties of the bed, and then the elasto plastic behaviours of the beam on this bed may be investigated. But the mechanical properties of the soil bed are so complicated that it is very difficult to solve the above problem exactly. In this paper, as an approach to the solution of this problem, the author attemped at first to idealize the mechanical properties of the foundation, and then discussed theoretically the elasto plastic behaviours of the long beam on this foundation. In results, he recognized that the behaviours of the above beam are conveniently related by a dimensionless parameterγ^^-.

The population and employment mix in medium-sized cities were analyzed with respect to following viewpoints. These are; (1) To find the conditions for self-sustained growth of medium-sized cities in the context of decentralization of population. (2) To develop the analysis on urban employment with special reference to "Minimum Required Employment for City (MREC)". (3) To re-examine economic base theory from the physical planning viewpoint. The data used were population and employment (2 digits classification) of 70 cities with 50, 000 to 500, 000 population in Chubu region in Japan. Followings are the facts found. (1) The larger the size of cities are, the less the growth rates of urban population terd to fluctuate. (2) There is sufficient MREC in the larger size cities in general. (3) The sufficient MREC is also found in the smaller size cities where stable increase of population is seen. (4) The sufficiency of MREC is concerned with the existence of urban area with the certain level of population density. These findings seem to have following implication for re-distribution of population. MREC is brought about presupposing the existence of population agglomeration with the certain level of size and density. MREC should be paid attention not only because it is paid attention not only because it is directly connected with the residents in cities but because it seems to contribute to the redistribution of population. In this sense, specialization of employment toward export sector as is seen in industrial cities is not advisable in terms of both the weffare of residents and the regional allocation of population.

I will discuss in this chapter, the arrangement of painted walls in the palace for the abdicated emperor, taking the same method as the preceding chapter. The summary is as follows : During Edo Period, fourteen palaces in all, were built for abdicated emperors. In six of these paraces, they applied painted Kokabe, though only one of them had their Kokabe painted in all edifices which composed the palace. In other palaces, they used either painted Kokabe or white plastered Kokabe, according to the function of the edifice itself. In every palace, they used white plastered Kokabe for the formal edifices and painted Kokabe for the informal edifices. Though, in early times, the painted Kokabe was applied in the palace under the influence of the Shogunate residences, it settled as the interior design of the palace for the abdicated emperor in the middle of Edo Period.
