The restoreing force characteristics of reinforced concrete elements based on the various tests results are presented considering the decrease of overall stiffness of the hysteresis loop according to the increase of the deformation. The force-deflection curve having the above characteristics is modelized by the N. C. L. Model composed of "Skeleton Curve" and "Normalized Characteristic Loop". Random hysteresis and its characteristics are shown in connection with the steady-state hystersis loop. Various factors which influence on the hysteresis such as element section, steel bar section, axial force of columns are to be presented in next paper. The static analysis of hysteresis based on the stress-strain relationship of materials, and dynamic analysis using the N. C. L. Model will follow.

In designing of bracing members in plastic design the following three aspects play a significant role : (1) spacing of the bracing members (2) strength of the bracing members (3) rigidity of the bracing members. In previous reports, I. II. III., the bracing space has already been studied for the case of the lateral movement of bracing point entirely constrained. In this paper an attempt is made to understand the rigidity problem in bracing members quantitativly by experiment; experiments and numerical analysis are mainly on the axial rigidity of bracing members. Experiments were made with a reaction frame; a general view of the test apparatus in shown in Photo. 1. As shown by the experimental results, the strength and rigidity of a bracing member has large influence on the deformability of the main beam. Ingeneral, the larger the strength and rigidity of a bracing member, the greater becomes the deformability of the beam. By the present experiment, the necessary rigidity in the bracing member, at the bracing space L/r_y=40 as specifid in the draft standerds is about 50% of that given in A. I. S. C's standards. The axial force in the bracing member can be about 3〜4% of the axial stress in the main beam. In the influence of the rigidity and strength of a bracing member upon the deformability of the main beam are involved the buckling effective length factor k and the movement of a bracing point u; these may be used to an advantage in the present problem. As described so for, the axial rigidity in bracing member has been studied by experiment and by numerical analysis and its quantitative grasping could be achived. For the pending rigidity, however, only its behavior was observed; and the quantitative study is in progress at present.

This study has been performed for the purpose of clarifying the actual state of "refuse disposal", "refuse disposal facilities" and "volume of refuse produced" in the office buildings. The results obtained are as follows; There is a : 1. The flow and the classification of refuse produced in the office buildings are in general as shown in Fig. 1. 2. The dust chute has such difficulties as stated below. a. Fire is liable to break out. b. It is as a whole apt to be a smoke duct at the time of fire. c. It is liable to be a source of birth of harmful insects. d. The dust collecting work in the dust pit is inefficient and not sanitary. e. Heavy weight substances will cause shocks when being dropped. f. The voluminous dust such as scrap paper is difficult to be cast in the dust chute. 3. The incinerator has increasingly been unpopular due to the following reasons : a. The personal expeditures run up to a large sum. b. It will be a cause of environmental pollution in urban area. c. The conventional type of incinerator is not sufficient for the increase of refuse comprising plastics, etc. d. Thanks to the appearance of shredders the need to burn up confidential papers is on the wane. e. The incinerator is liable to be a source of fire accident. 4. The dust press is a machine to compress and solidify the waste mainly composed of scrap paper to 1/4-1/5 in volume. Although convenient for storage and transportation of dust, the press has still such shortcomings that the press operation is troublesome and the reclaiming of scrap paper can not be performed. 5. The refuse cooling compartment is a room where refuse is kept at low temperature for the purpose of preventing putrefaction of refuse, generation of offensive smell and birth of harmful insects from being accelerated. 6. The refuse storage facility is that which keeps for a certain duration of period the refuse classified as per the day of production, so as to be able to find out the necessary papers and documents lost among refuse. 7. The volume of refuse being produced per 1, 000 persons in the office buildings amounts to 2.5-4.0m^3 per day. 8. The composition of the volume of refuse by classification will be about 5 for refuse packed in hempen bags, 3 for refuse out of containers and 2 for that in containers. Of the refuse in containers, the feed for the domestic animals to be taken away by the livestock producers will occupy about 15 through 40%, but the larger the buildings, smaller the ratio. Of the above refuse out of containers, namely the solid refuse the quantity to be taken away for reproduction by paper material dealers will be about 30% and is mainly composed of empty corrugated card board boxes. The waste to be taken away for reproduction (including the feed for domestic animals) will be about 60% of the total refuse being produced. 9. The volume of refuse being produced in a day is almost constant throughout a year except on Sunday, Saturday and national holidays. However, on the 30th day of December the refuse two or three times larger in volume than in an ordinary day is produced. It is also said that the waste is especially large in quantity on such a day as a tenant moves out.

In 1879, the Kaitakushi (Hokkaido Colonization Board), sent to the Vladivostok district and the Sakhalin Island, Russian empire a technical study group to study the construction of log houses and the petica (Manchurian stove). The Kaitakushi employed workmen from those areas to have them build a school, house, and dormitory of logs in Hokkaido from 1879 to 1881. These buildings had petica. Thus, the Kaitakushi tried to popularize Russian architectural techniques in Hokkaido. This, being the first introduction of the Russian architectural techniques into Japan, is an apparent historical fact. This report introduces the history of the Kaitakushi's policies on the introduction of architectural techniqucs. It also considers the Kaitakushi's intentions, the fact that the introduction of Russian techniques ended in failure, and the reasons.
