This Part 3 refers to the flow properties of such sprayed fireprotection materials in pipe as the vermiculite plaster or rock-wool cement mortar. The following results were obtained. a) Assumming that these materials are of Bingham body with the slip layer on the glassy surface of rigid wall, the theoretical equation of flow properties can be expressed as the function of pressure loss, rheorogical properties of used materials, velocity, pipe length and radus of pipe. b) The calculated pressure loss based on this equation has a good agreement with the measurement results on the actual pumping shown by the previous Part of the report.

The purpose of this paper is to study the characteristics of polymerization on polymer impregnated concrete (PIC) polymerized by various radiation source which have the peculiar energy respectively as follows; Gamma-rays : ^<60>Co-1.25MeV, ^<137>Cs-0.66MeV, X-Ray : 0.88MeV and accelerated electron beam 4.0, 2.0 and 1.2MeV. This experimental program was carried out to investigate the effect of radiation energy, dencity of cement mortar, optimum irradiating conditions and other factors which have influence upon the polymerization and strength of PIC. The test results shows that the energy dependency on the accelerated electran was remarkable effect for relative absorption energy and strength of specimens (Fig. 5) and it can be estimate that the impregnation depth from the surface of specimens in ordinary mortar MMA-PIC were about 10mm, 6mm, and 3mm as to 4.0, 2.0 and 1.2MeV respectively under curing 50 Mrads (Fig. 2). It is also show that the optimum total exposure dose on magnetic electro wave methods, estimate about 3MR at ^<60>Co; 1×10^6R/hr, 2MR at ^<137>Cs; 4.5×10^4R/hr and 2MR at X-ray; 5×10^5R/hr at curing temperature 20℃ (Fig. 9, Fig. 10). We can see the fact that the energy dependency is noticiable only comparing same kinds of radiation source.

The paper reports on experimental research conducted on the influences of shear wall arrangements on the failure mechanisms of frames with shear walls. The test specimens are frames with shear walls in checkered and multistoried arrangements, and it is confirmed that different failure properties are indicated against lateral forces. With a multi-storied shear wall, bending shear failures of boundary beams and frame columns for connections between two coupled multi-storied shear walls precede with collapse mechanism ultimately produced by shear walls yielding in flexure. In contrast, with a frame having checkered shear walls, the entire resists external force as one until very close to maximum load and fails ultimately in shear failure of shear walls at the inner spans.

In this report necessary precautions to be taken against reinforced concrete slab damages by large deflections are discussed on the basis of the results of the in-situ observation of such damaged slabs over 1100 in number, including cracking patterns, measurements of sags, mechanical properties of concrete and cross-sectional construction errors. Consequently, such a limiting relative slab thickness as the smallest that does not incur the large deflection of a certain prescribed amount is derived from the relation of the amount of sagging with either of the concrete stress due to negative moments and span/thickness ratios.

The purpose of this study is to devise a simple kinematic model representing overall behavior of a framed structure under earthquake excitations. The well-known fact is that an equivalent continuous system is a useful mathematical model to calculate responses of a framed structure composed of discrete members. Although many investigators have used such a model, most of the works have dealt only with elastic response analyses. Efforts are still insufficient to incorporate inelastic responses of a structure, which are undoubtedly important in the aseismic design. The authors showed in the previous paper (Part 1) that inelastic responses of a framed structure were strongly affected by the yield interaction between forces acting at a story. The present study develops a yield interaction equation that is a function of a story shear force, a story axial force, an overturning moment and transverse forces on the beams due to gravity and dynamic effects. From this equation an equivalent continuous system is devised, which is a mathematical model for an inelastic framed structure incorporating the effects of yield interactions between those forces, work-hardening of material and P-⊿ effect on whole story. Further, numerical examples are given. The results show that the proposed method gives reasonable approximations for overall responses of the structure such as a shear force and horizontal displacement of each story, as compared with a more accurate but complicated analysis. The present method may be applicable to seismic response analysis of multi-story framed structures.

Dynamic behavior of wooden structures and soil layers in Nagoya is estimated by considering the seismicity, soil properties and composition and vibrational characteristics of structures. Seismic conditions in future will be predicted by a small distance earthquake and a long distance one, on the basis of the past damage earthquakes in Chubu district. The grounds in Nagoya city area are idealized as horizontal soil layers. Their depths and soil properties are given deep well boring data and seismic wave tests. Structural properties by fundamental periods and critical damping ratio. Dynamic responses of structures on 173 sites in the city are analysed and microzoned according to the damage level. Predominant period distribution map on the ground surface is developed by the microtremor measurement. Seismic damage potential is illustrated by comparison with seismicity, ground conditions and structural properties.

In designing multifamily dwellings which are adjacent each other through a party wall or floor, it is natural that the greatest importance should be attached to the prevention of internal noises. According to the answers to the questionaire put to people living in multifamily dwellings, most of the complaints centered around the sound coming from the above flat. As shown in Table 2, 3, 4, the majority of sound sources are impacts transmitted through the floor, e. g. jumping or running of children as well as plumbing noise in the lavatory and bath room above. On the other hand, A-weighted sound level which are commonly caused in the apartment house by the daily life of the neighbouring families having children were measured for 24-h period in the 13 vacant dwelling units shown in Table 8. On the basis of the measurement, the basic data on inhabitant noise were arranged, and as shown in Table 9, averaged peak sound levels, durations and numbers of impacts each 30 minutes were obtained for respective noise sources. In order to evaluate the inhabitant noise, Total Noise Exposure Level (TNEL) for indivisual noise sources were calculated (Table 10). According to the sound insulation grades of building, obtained TNEL data were classified into 3 groups and compared with the frequency of noise complaints in Table 11. As the result, TNEL_<30>' calculated by formula (2) showed a quite well agreement with the frequency of internal noise complaints pointed out by residents. From this view point, it is considered the evaluation of inhabitant noise using TNEL should have been one of the useful index in designing multifamily dwellings, and the 24-h average TNEL would have been reduced to 55 or so.

By using steer's eyes, which are similar in optical characteristics to human eyes, we have measured the stray light in them. (See Table 1). The results are summarized as follows : 1. The effect of time lapse after the excising of steer's eyeballs is negligible at least up to 10 hours. (See Figs.2〜4) 2. The quantity of stray lights increases as the light source approaches a point on the visual line, especially when the light source is within 10°from the visual point. (See Fig.5) 3. The causes of stray light are : (1) optical defects of eyes when the light source is within 10°of the visual point; (2) diffusion of light on the surface of the cornea at angles greater than 10°. 4. The smaller the iris aperture, the smaller the quantity of stray lights. (See Figs. 6 and 9) 5. When a large light source is divided into 1°units, the total sum of the stray light from each unit is almost equal to the quantity of the original light source. (See Table 4) 6. In order to obtain the ratio of E_θ/E_0, the following equations are used : θ>1° E_θ/E_0=exp{(-lnθ)^3-0.25}+0.032θ^<-1.8> θ≦1°E_θ/E_0=exp(-0.17θ) where, E_0 : Illuminance of fovea when the light source is on the visual line (θ=0°) E_θ : Illuminance of fovea when the light source deviates θ°from the visual line.

In part 2, the calculation method and the field observation of the earth surface heat budget were described. In this paper, first, the result of the annual calculation on the architectural scale of the earth surface heat budget is described (Osaka, 1970). The annual mean surface temperature of the building roof and the asphalt pavement is higher about 2℃ than the grass and the forest. The temperature differences between various land uses are large, particularly at summer season. The sensible heat flux is large at the asphalt pavement and the building roof, and the latent heat flux is large at the water surface, the naked ground and the green area. Secondly, the result of the diurnal calculation at summer season is described (Osaka, August, 1966). The differences of the earth surface temperature between various land uses in the daytime are more larger than the result of the annual or monthly mean surface temperature. On the monthly mean of daily max surface temperature, the asphalt pavement and the building roof are higher about 10〜20℃ than the grass and the forest. The heat fluxes of various land uses are remarkably on the sensible heat and latent heat. The sensible heat flux of the asphalt pavement and the building roof is much larger than the grass and the forest in the daytime and the sensible heat flux of the asphalt pavement and the building roof is more than 200kcal/m^2・h at some days. The sensible heat flux of the forest is generally negative value. One of the reasons was considered the same phenomenon as the 'oasis effect', because the meteorological data used was observed in the centre of the city. Accordingly, the latent heat flux of the forest is large.

In this report, we evaluated dwelling units of the public houses designed specially for the handicapped (=wheelchair users). (1) The total marks, which the type of units with the (L) DK joined to a room obtained, are more than those of the independent (L) DK type. (2) The south side DK-type obtained more evaluation marks than the north side DK-type. Because, in case of the north side DK-type, it results in passing through the Western room on the north side. (3) The unit type obtained most marks is the plan that the south side DK-type is connected with a room. But this type belongs to the fewer unit type which is built really. (4) As a result of evaluating each rooms in the units, the (L) DK and Western style room are narrow and the space for furnitures is not under considerations.

Before 1975, as the outcome of selling to pay the tax their farms and giving brothers their farms, there were many cases in urban district that the scales of their farms decreased so much and their managements got into danger. But the special system of tax was made to make better such conditions in 1975. This paper analyses that the becoming the head of a family influences the farm management through cultivated land for their preservation program.

The environment of the high densely built-up area is determined primalily by the changes caused by the reconstruction. It is the relation of the house and the next house that changes worse. This relation of the houses is supported at confortable condition by dwellers' rules of planning houses. Realy, there are the rules in the high densely built-up area continued a long time, but now, the rules are collapsing and in consequence the environment of the city has changed worse. In this paper it is proved that this collapse of the rules is determined primalily by the conscious of "public". We ask to people living a long time in high densely built-up area the conscious of using the alley, the sence of resistance to go into the alley, and the conscious of considering surroundings in reconstruction. In consequence, the men who answered that the alley should not be used because the alley is "public" have lower conscious of considering surroundings, and the men who answered that the alley should not be used because it is theirselves' have higher conscious of considering surroundings. And, there is clear difference of the conscious of "public" in the each collection around the same alley. It can be explained only by the situation of the alley, that is analized in "Structure", "Organization", "Compornent". The collection that have the conscious of "public" and the lower conscious of considering surroundings is determined by the alley that the "Structure" has public situation becauseit is pass-road used by every person.

There is no definite opinion concerning the starting point of the "Queen Anne" movement. But architectural exhibition at the Royal Academy in 1873 was an important evident for the social recognition of the "Queen Anne". The central figuares of this event were John James Stevenson and Edward Robert Robson. J. J. Stevenson was energetic for making "Queen Anne" popular as a writer and an architect. His own house the "Red House" in Bayswater was one of the first example of the town house in that style. After the Red House, Stevenson designed many houses in London in the same manner. E. R. Robson, on the other hand, was an architect of the London School Board established as the result of the Education Act of 1870. His design for the Board Schools were typical "Queen Anne". J. J. Stevenson helped him in designing schools, so both were responsible for that design. Both Stevenson and Robson made great contribution for establishing the "Queen Anne" style in London and for making it popular in London. The "Queen Anne" was essentially a style for town buildings, and here was the key why this style was so rapidly accepted in 1870s.
