This paper is to follow the previous part 10 in which the experimental results of the beam tests to investigate the mechanical properties of metallic skeleton reinforced inorganic matrices structures are shown. In the experiments bending performance of the beams, consisting metallic skeleton reinforced Gypsum paste and Gypsum light weight aggregate matrices or aluminium skeleton reinforced inorganic matrices, are examined. In this paper the experimental data are analysed and the conclusions as follows are indicated. Concerning on aluminium or steel skeleton reinforced Gypsum concrete or Cement concrete matrices beams it is possible to design the components of the structure basically following the current standard of steel reinforced concrete. Yealed strength and stiffness are able to be estimated by the suppositions of the section of the beams keeps plane under the load and the tension side of the matrix is ignored. As for the bond properties between reinforcing bar and inorganic matrices there are two important matters as follows derived from the analytical results. By the round aluminium bar it is difficult to get enough bond strength in inorganic matrices like Gypsum paste, Gypsum concrete and cement concrete. So the deformed aluminium bar is necessary to be used for the skeleton reinforcing the inorganic matrices. To reinforce Gypsum past or Gypsum concrete matrices roundsteel bar is not suitable for its quite little bond strength, then deformed steel bar is to be chosed for matrices made from Gypsum.

The Part 2 touches upon the pumping properties of sprayed fire protection. The laboratory test was done on the fresh state properties of fire protection and the pumping properties were researched by the field test using various materials. The obtained results are as follows; a) The flow value or cone penetration value as the index of workability has linear relation to the water material ratio for each materials. b) The flow resistance, which is obtainable by dividing pressure loss of unit pipe length by velocity, is correlated with these value at each materials. c) The above results show that the flow value or penetration value is useful as the index for supervision of pumping work.

Dynamic behaviors of a reactor building when subjected to severe earthquakes were analyzed and discussed in the light of experimental facts. A model reactor building for dynamic analyses had all the same structural features as the tested specimen except that it was 25 times size and had additional steel framing at the top floor portion. Weights located on every floor were decided so as to correspond to actual loads. A vibration model was idealized to have lumped masses which were interconnected by flexural and shearing elements to each other. Strength deformation characteristics of elements were already formulated by a proposal in the previous part of the paper. Then, nonlinear dynamic responses of the model to the input ground motions were computed using step direct integration method. The results of responses to strong earthquakes with maximum acceleration up to 600 gals were summarized as follows : 1. Due to the strong ground motion, a model structure always entered into nonlinear ranges. For instance, flexural and shearing yield specified by the test results occurred against earthquakes with maximum acceleration of 400 gals or more. 2. Structural damages estimated by the test results were, however, very minor even against the worst earthquake with 600 gals. Comparing the ultimate strength and the largest deformability with those of response values, it was concluded that the safety factors of the model structure were satisfactorily assured.

Experimental results of 3 story 3 bay braced and unbraced frames under monotonous or alternating horizontal forces are shown in this paper. The test program consist of four specimens. Two of them are braced frames and other two are unbraced frames. Both braced and unbraced frames are designed against the same factored horizontal forces, and individual members are processed to have a net strength. Test frames are subjected to horizontal forces which are proportional to design forces at each floor level. It is generally observed the force-deflection curves do not differ remarkably from the test results which have been presented by many investigators. As to the braced frames, bracing members of the lowest story which has the smallest ratio of story shear-force shared by bracings to total shear force buckle and yield at the outset, so the relative story displacement of the lowest story increases before buckling and yielding develope in all other bracing members. After this, however, the relative story displacement of each story increases uniformly. This result suggests that the bracing members should be designed so as to buckle or yield simultaneously against seismic force. Further, experimental force-deflection curves are well predicted by generalized hardening hinge method.

A realistic soil layer consists of remarkably nonlinear medium with hysteretic characteristics. Such a soil medium has a strain dependent behavior on rigidity and damping. The order of strain level of the ground subjected to strong earthquake motion is (10)^<-4> to (10)^<-2>. It is indispensable to estimate the nonlinear dynamic behavior of soil layer under strong earthquake, corresponding to strain dependent rigidity and hysteretic characteristics. By step-by-step integration technique, the motion of discrete lumped mass system for a soil layer is solved. The surface motion in maximum displacement, acceleration and amplification factor in time domain is obtained. The response spectra and Fourier spectra of surface waves are also analysed. The typical properties of nonlinear dynamic response of the ground are pointed out.

The behavior of single piles or pile groups due to negative skin frictions induced by ground settlements are studied in this paper. Fundamental equations were already shown in serial report Part I by authors. Authors tried to clarify that this theory is applicable to site phenomena observed by using various efficient apparatus. Some important points on analysis about negative skin friction phenomena should be as follows, 1) estimation of skin frictional strength and their distributions 2) ground settlement quantity and their distributions 3) rigidity of ground explained by appropriate conception of soil model 4) stratified situations of ground 5) scales, compressibility and number of piles 6) interaction between piles and ground. In this paper facters 3), 5), 6) mensioned above or partially 4) are mainly considered. Another facters are treated mainly as known quantities from observed data. In this report three observed data (EX. 1, 2, 3) are picked up as follows. These are all steel pipe piles driven into about 40 meters clayey deposit. EX. 1 three single piles (one 31 meters and two 43 meters long piles) EX. 2 one single pile and 2 or 5 pile groups at 2.5 diameters spacing about 40 meters long EX. 3 one single pile and 38 pile groups at about 2 diameters spacing about 40 meters long Relations between observed data and calculated results about axial force distributions, neutral points, pile top settlements and their pile group effects are discussed. In conclution authors consider that our theory fairly applicable to site phenomena.

In the first half of this report, a comparision of the test results and the simulative computation is discussed on the distribution of air temperature and the buoyant air circulation in the actual size room. For the simulative computation of this case, two kinds of boundary conditions are considered as follows, 1) using the measure temperature of each wall, 2) calculating the temperature of wall surface by solving the heat ballance equation including the interreflective radiation between the walls. For the actual use, the second calculation is indispensable. In this report, each of the surrounding four walls is divided into sixparts, and to simplify the calculation of the radiation from the linear heater (convered with aluminum ware), whole heat is assumed to be supplied by convection to the air going through the heaters. The results of computation and the actual situation in the test room are very much similar to each other in the points of the distribution of air temperature and the character of air flow. Particulary, the stagnant vortex appeared in the internal zone of the room is alike the traced results observed by using pappi of dandelion. In the latter half, the thermal conditions in the case of exhausting the cold draght down from a window into the hole on the floor are referred. And this exhausting method has as good effect as in the case when a warm air outlet is set below the window.

The main purpose in the series of these reports is proposing the guide how to plan the dwelling unit of the public house for households with the handicapped. In this report we study on the housing level and the trend of the dwelling unit plans designed specially for the handicapped which have been built up to the present. Conclusions are as follows : (1) The dwelling units are all for the wheelchair users. (2) The floor area, which shows the housing quality, is on a level with the unit for the general household and on the low level for the handicapped. (3) The planning policy for the room arrangement in the units is not found and the unit plans are various. Because the house living image for the planning is not established. (4) The DK-type unit occupies the greater part of dwelling units and the 2DK unit has been most built. The main type in the 2DK unit is that with the DK on the north side. (5) As some features of room arrangement planning, we recognized joining the DK with an adjacent room, securing an isolated private room, the Western style room for the handicapped and the Japaness style room with floor level up +450mm. (6) Wheelchair users are able to approach to each rooms in the unit. But two routes to retire to a safe space are not always secured in the units. (7) The plan of the units are influenced by the approach types in the housing block. In most cases the entrance for the wheelchair user is located on the north side of the unit. It is more difficult to plan in the housing block to approach over the staircases.

"Waga Yado" is an idiom which stands for "my residence" in Japanese language. This idiom creates a problem in the history of Japanese dwelling house because when this idiom was evolved. The word "Yado" meant etymologically not a "house" i.e."Ya" but an "outer-space" i.e."To" or even an "openning" i.e. "To" of a building ("Ya") in ancient Japan. To determine precisely the age, and the process through which this idiom was evolved, the author researched this word thoroughly in the four areas of literature completed in the 8th century ("Kojiki", "Nippon Shoki", "Fudoki", and "Manyoshu"). He discovered about 120 words in "Manyoshu", an anthology of about 4, 500 poems of ancient Japan, and determined the following points. 1. The first poem which has "Waga Yado" was composed in the reign of Emperor Tenchi (662-671 A. D.), though this "Waga Yado" did not mean "my residence" at the time. 2. In several poems composed in 730 A. D., we clearly find that the idiom had been incorporated into the language. 3. Upon comparing these instances with other "Waga Yado" before 730 A. D., the author found that the first "Waga Yado" which stands for "my residence" occurred in the poem by Prince Fozumi composed in the beginning of the 8th century. At the same time, the author found that the 8th century poems which have "Waga Yado" in "Manyoshu" always speak of plants in a garden such as "Hagi (bush clover)", "Tachibana (orange)", "Ume (plum)", "Nadeshiko (wild pink)", etc., or the Moon, Birds, Wind and the like. So we can say that the expression "Yado" i.e. "residence" is always found up in those poems with the "petit and intimate beauties of Nature". On the other hand, one of the most traditional characteristics of the history of Japanese dwelling house was that the dwelling house always had a garden in which the householderes could live with and enjoy "petit and intimate Nature". This carried throughout history untill the 19th century. Another problem in the history is when this tradition actually began. In conclusion, it is the opinion of the author that the evolution or the invention of the idiom "Waga Yado" coincides with the formation of this "Nature" tradition in the history of the Japanese dwelling house.

There were several architectural works which had certain "Queen Anne" motives before 1870s. Here were examined such demestic works by Philip Webb and George Devey. The house at 1, Palace Green, London, designed in 1868 by Webb seems "Queen Anne" for its sash-windows and segmental arches in red brick wall. In the course of designing this house, there were some trouble between Webb and J. Pennethorne, the architect of the Commissioners of Woods and Forests, over the style of the house. But it was a battle of style between Classical architect and Gothic one, and not the revolt of the 'Queen Anne' architects against the Gothicists. In Webb's work, there is another interesting forerunner; 14, Holland Park Road, London, designed in 1864. This house was enlarged twice in 1877 and in 1892. The enlargement shows how the original Gothic-like house which was similar to the Red House in Bexleyheath, Kent, grew into the "Queen Anne" style. At the same time the process shows the Gothic elements in the "Queen Anne" style. Concerning Devey, views among scholars differ on his importance. British scholars usually regard him as the impotant pioneer creating the new style, whereas foreign scholares do not place him such a high position. In Devey's work, especially country house Betteshanger in 1861, we find the first revival of Dutch-gable and other non-Gothic features. Although their uniqueness and novelty in detail and composition, both Webb and Devey remained within their own architectural world and they did not publish their works. That was the reason why their influence did not spread rapidly among younger architects who were anxious to creat new style. In that sence, Webb and Devey were not the creater of the "Queen Anne" fashion, but isolated forerunners.
