These experiment have been performed to investigate the bond strength of reinforcement in concrete cast into the bentonite suspension and the compressive strenght of that concrete. In this method, the bentonite suspension is always in jected, as the drilling proceeds, to prevent the wall surface from falling and then concrete is poured into the bentonite suspension using tremie pipe. It is feared that the compreesive strength of concrete and the bond strength of the reinforcement may decrease as the result of the in perfect replacement of bentonite suspension with concrete. These expreiments were performed to clarify there points and they consisted of the two experments, one of which was the model experiment in the laboratory and the other was the experiment performed at job sites, The results of the experments show that the compressive strength of the concrete cast into the bentonite suspension about 13% concentration is lower than that of the concrete cast in ordinary way, and in the concrete cast into the bentonite suspension below the value, it does not decrease so much. However, at the top end and the both side ends of the concrete wall cast into the bentonite suspension, consiclerable decrase of the compressive streugth is observed. As to the bond strength in the concrete cast into the bentonite suspension, it is found to be lower than that of the ordinatry concrete and the following formula for the relation between the concentration of bentonite suspension and the bond strength is suggested. ^τx=α・τ_c(1-βX^2) where; X=concentration of bentonite suspension (%) τ_x=bond strength (kg/<cm>^2) for concrte poured into bentonite suspension with concrete of × % τ_c=bond strength (kg/<cm>^2) of ordinary concrete. α, β=coustants Further, it is shown that the bond strength of concrete decreases considerably when the bentonte suspension is gelatinized by Ca^++ ion of the cement. And the bond strength of ths concrete at the top and the both side ends of the wall is also found to decrease.

Though the flow pattern is affected by the roughness of the ground surface, the turbulence of the natural wind, and the configuration of the building, the author tries to get a two-dimensional solution of the pressure distribution on the wall and roof of buildings subjected to a uniform stream, such as factories with or without monitor, by the image method of the potential theory, on the assumption that the air is an ideal fluid, that is, invicid and and incompressible without temperature change, and flows along the wall and roof surfaces, with separation starting at the roof ridge. The purpose of this paper is to provide useful information on the design of the building under the wind pressure, which is easily calculated with the help of the table of modified elliptic functions attached to the end of the 2nd Part of the series of the papers to be published in the following month, though the derivation of the equations seems rather difficult due to the elliptic funcions involved. The appropriateness of this solution is verified by the experiments as presented in the successive parts of the series in special cases, although it looks reasonable at the first glance. In conclusion. the distribution of the wind pressure on the surfaces of the building, which has had so far recourse to the experiment in the wind tunnel, can be fairly estimated by this calculation method in some cases.

The total cost of the exterior skin of the building is discussed in this report, relating with building forms. The quantitative study on the building elements made out the relation between exterior skin area and building forms in the following formula. [numerical formula] R : roof area (m^2), E : exterior wall area (m^2), A : total floor areea, n : number of stories h : floor height, k : ratio of sides in typical floor This relation is shown in Fig.5 by graph. Then the unit cost of wall and roof were introducod this formula. When "A" is fixed, "n" that wakes exterior skin cost minimum is given hereunder, [numerical formula] C_r : unit cost of the roof (yen/m^2), C_e : uint cost of the exterior wall (yen/m^2) This means that (C_r/C_e)^<2/3> times "n" which make the total exterior skin area least, make the total exterior skin cost last Actuay, the exterior wall cost slides according to the "n" of the building. But this extent is very much difficult to seize. Because, there is no building which have same facade but have different "n". According to the economic study on heigh rise building by J. B. A, the relation between exterior wall cost and "n" are as followes in the same fasade. C_e=180n×19, 600 Using this factor, more acculate estimation on "n" which gives minimum exterior skin cost is possible, but "n" can not be solved generally in this case, may be solved unmerically by E. D. P. only.

The method of reserch about human behaivior in the liviing life has chiefly depent upon "Living style", that is, the comprehension between the object of behaivior and the function of space. But however, it has not necessarily paid attention to reserch the special patten of behaivior, through which the function really appears. Nowadays it becomes more difficult to classiby the behaiviors according to their objects on account of their complicated characters. The question is to make clear what is key point adjusting numerous behaiviors in the living life. We find it out that, "Danran", Fire Round Sitting should be the key behaivior in future. A summary is as follows. 1) "Danran" is one of the joious coumunication between one family. 2) It's communication corresponds to a group of behaivior, which are dinner, TV, conversation etc. 3) The communication between one family appears to the privacy for other human group. Privacy is an another side of conmunication. 4) The pattern of conmunication and privacy changes to different pattern according to the growth of family.
