    From the results of some three-storied walls with opening subjected to uniformly distributed lateral loads was analyzed by a lattice analogy, the distributions of the stresses, σ_x, σ_y and τ has been shown in Part V which has the same title. In this report, the distributions of the maximum and minimum principal stress, the directions of those principal stresses, the stress concentrations at the corners of the rectangular opening, the ratio Q_w/Q between the shearing force produced in the wall part and the story shear, the position y_0 of the inflection point on the column, the shearing force Q_b of the beams and the axial force N of the column at each story, and the bendiing moment M transmitted from the column bottom to the base are investigated.

    In this paper on reinforced concrete rectangular slabs with four edge beams, the influences of the variation of loading conditions, rigidity of edge beams and reinforcements on elastic and plastic behavior of slab, especially mechanism of failure, ultimete, strength and arching action are discussed. For this purpose eight rectangular slabs were tested and the next results were obtained. 1) The ultimate strength of rectangular slab with edge beams is far in excess of that predicted by Johansen's yield-line theory considering only the bending strength. The main reason may be the srching action induced in the slab. 2) The effect of arching action in slab has a tendency to be large, when the edge beam is rigid, the loading condition is nearly uniform. 3) The slabs are divided into the triangular and trapezoid shapes in case of Uniform loading, and the radial shapes in case of concentrated loading at the final failure stage.

    It is unavoidable problems that piles which are driven into earth incline more or less by means of precision of construction method such as sorts of pile driver and connection of joint parts and by means of ununiformity of ground such as sorts of geology, thickness of stratum, softness and hardness and so on. Author put in practice formerly the experimental study on the ratio of diameter and length of pile, and also analytical study which is based on the proper assumption to inclination angle and inclination pattern of pile is carried out and he has reinvestigated to the ratio of diameter and length of pile. However, as there are little measured data on the aspect of inclination angle and inclination pattern of pile, under the present condition, there are only one or two measured data. This time, as we were got many reliable results of the research on the actual condition on inclination of pile to the state of driven PC pile, made by the way of centrifugal force, in the fields, we investigated on their inclination angle and inclinaton pattern.

    As a results of rapid development of engineering science in Japan, new technics are being put in practical uses in the field of air-conditioning, electric lighting and other mechanical installations of buildings lately, and the need of new design data to comply with such new technics has become ever more pressing. However, some of the design data presented in the past has become to be totally impracticable to apply to new buildings without modification, and it is clearly evident that these established data must be surely re-examined. What is needed, therefore, is new data based on new findings that can be used as design criterion or data for the buildings of tomorrow. This paper describes an analytic solution, which hcs been formulated through analysis of innumerable statistical data summed up in the past several years on the electrical equiment and installations of the buildings so that they may be conveniently apply to the electrical design. By the use of this statistical solution, the capacities of electrical load and transformer per unit area of office, store, hotel and residential buildings can be summarized as shown on Table-11. And up to now, the following equation has been generally used to assume the approximate area of the substation of a building. A_t=3.3W_t^<0.5> where, A_t=Area of substation (m^2) W_t=Total transformer capacity (kVA) However, it is considerd from the results of the investigation that areas of the substations of the buildings constructed during the past six years are distributed in closer proximity along the lines of the following equation than the established equation referred to hereinbefore. A_t=K_sW_t^<0.7> where, K_s=A constant based on the design of the substation =0.96 for high tension receiving voltage

    The government office buildings are led to be worn physically, functionally and socially as the years pass by. They are led to lose their effect and to be reconstructed finally. Because they are influenced strongly by the in and out factors. The formers are the buildings factors, and the latters are the social, economical and administractive factors. I study these phenomena considering the condition of reconstruction of the government office buildings.

    The span of storeyed tower decrease in proportion to upper storeies. Generaly the rate of decrese is high in the ancient tower, and it is low since the mediaeval tower. But the rate of decrease in the modern tower does not nearly deffer from the mediaeval tower. Because, since in the mediaeval age the span is set on the basis of Shiwari, and so the decrease is beyond its control by the limitation of the rafter's number. It is later than the architecture of single storey that the rule of Shiwari is completed about the tower. It is difficult that unify several storeyed spans by same Shiwari taking the decrease of each storey into account. In case of five storeyed-tower, at the bigining the rule of Shiwari is used only first storey for example Kaijyusenji tower, next Shiwari of first storey used only to decide full span (span consits of a central and tow side) in over second storey for example Myooin tower, lastly all storey's span is unifyed by same Shiwari for example Itsukushima tower. But several tower use transitional way (each sotrey uses individual Shiwari) until the middle of 15 C. In case of three storeyed-tower, as number of storey is more few than five storeged tower, Shiwari is completed easily.
