In this report, the results of experimental studies on the effect of water-cement ratio. air-bubble content and volume of rightweight aggregate per unit volume of concrete on the compresive strength properties of natural cured cellular concrete, and to improve compresive strength of cellular concrete through variation in mix-proportions and addition of lightweight aggregate are described. The results are as follows. (1) The compresive strength of natural cured cellular concrete is depends on the void-cement ratio. (2) It becomes an effective method to increase the compresive strength and young's modulus of natural cured cellular concrete, that addition of lightweight aggregate. Increase of unit weight of cellular concrete, by addition of light weight aggregate, is a little.

Structural steel change its mechanical properties when they were subjected to various types of plastic hysterisis. In this paper, several distinguished changes of mechanical properties are pointed out as the result of experiments, in which SS 41 and SM 50 previously given plastic tensile strain were subjected to tensile and compressive stress and furthermore to the alternative stress.

In the preceeding paper of same title (part 1), the in-put loss of earthquake power, caused by horizontally restricting a phase difference of earthquake motion appeared on a ground surface, was argued with the help of several observed data. And a typical characteristic of in-put loss was also given by assuming a simple model and wave transmission. In this serial paper (part 2), the computer technique which gives a similar filter characteristic to that of in-put loss was devised, and the method of obtainning the effective in-pnt from an original ground motion by analytical meas was shown. The method was trially applied to an actual observed data, and the calculated result was proved to be very similar to the observed record. The change in response spectrum of the effective in-put was also shown in this paper. As the result of this investigation, the effect of the in-put loss can never be disregarded for a building having horizontally larger scale or comparatively shotrer natural period when the earthquake response of which is discussed.

Generally speaking, we have two methods of seismic design for buildings in Japan : one for multi-storey buildings which are below 45 metres in height, and the other for high-rise buildings which are over 45 metres in height. The former is the static method which is decided in Japanese building code, and the latter is the dynamic one based upon the response analysis of buildings. When we consider the former seismic design for multi-storey buildings, it becomes doubtful that the static seismic coefficient 0.2 which is decided from the engineering judgement is fit to the fact, because seismic forces which are transmited into buildings during earthquake are different according to the natural period of buildings. Unless we apply the dynamic analysis for multi-storey buildings, we can not catch the real behavior of them during earthquake. In this study, the linear and non-linear response analysises of four types of the multi-storey reinforced concrete buildings during earthquake are executed.

Many structures were damaged by the earthquake off Tokachi in Japan in 1968. But some structures were not damaged by this earthquake, and Hachinohe Nisseki Hospital was one of them. It is important to study not only structures which were damaged, but also those which were not damaged. It is interesting to study Hachinohe Nisseki Hospital by a dynamic analysis. This Hospital is 7 story reinforced concrete structure, and is designed statically in conformity to the seismic coefficient 0.2 which is decided in Japanese building code. In this study, the linear and tri-linear response analysis of this structure are executed. As the result of the response analyises, it is presumed that the maximum acceleration of the Tokachi earthquake which this structure was subjected to would be 80 gal.

The pattern of home circle is provided with family hours with which they spend together. The results of survey are as follows. 1. The family hours is decided with the husbands working hours. 2. The family of no child has relatively home circle hours. 3. The family of which first child is elder than seven yearsfold, has little home circle hours. Because the husband is caused to work late at night on his business and his wife is engaged with daily sitting. 4. Old family recover its hours again and also its member has a little private hours. 5. The more the private hours they have, the more extend its needs.

In the main fruit-growing districts of our country, a yearly increase of production now requires that market cotrol should be strengthened by dint of the continual mass shipment of products. With the increase of production, the serious shortage of labor has come to be an acute problem year by year. A packing house is built to settle this problem. In this study, we take up a packing house as a part of the study of architectural planning for distribution facilities; especially we pursue the study of architectural planning and district planning for an orange packing house, which has made the most amazing progress in its automation and its large-scale. In this paper we consider the result of investigation of its actual state and some concrete matters found inside it through the information from the nation-wide questionaire and the actual survey of several typical packing houses.
