In this paper, I report the settlement ratio of structures (observed retative settlement/computed relative settlement). The results are as follows. 1. The practical equations of the settlement ratio of structures are reported in this paper. 2. The observation results and theoretical results by model structures are generally in fair agreement. 3. The settlement ratio of structures are much influenced by the number of storys, the slenderness of members, the settlement value of structures and the rigidity of concrete walls.

In this paper the lateral buckling tests of parallel beams with lateral and/or sway bracing between them are carried out and the bracing effects on the buckling strength of main beams are discussed. Total of eleven specimens are tested under uniform bending and the results of critical moments, buckled confiigurations, effective length, are investigated. Bracing forces are also measured during test.

As we live today longer under the ground with increase of subways and underground markets, it is of much importance to take care of air quality in the underground environment not only in the ambient atmosphere. This paper reports the experiment on the suspended particulate matters concentrations in the subway air which was carried out from July through November except August in 1972 at the subway stations, Ginza's of Hibiya line and Marunouchi line and Hongo-Sanchome of Marunouchi line in Tokyo. In ambient air there was no significant difference between suspended particulate matters concentrations of Ginza and Hongo, whereas there is a significant difference in the subway, which is due to the difference between the numbers of passengers at both stations. Diurnal variation curve of suspended particulate matters concentration of week day (days except Saturday and Holiday) shows two peaks at 9.00 and 18.00, rush hour respectively in the morning and in the evening. On Saturday the morning peak is as high as on the week-day but there is not evening peak, and on Holiday there is no peak and concentrations are almost constant through a day. The ratio of particulates concentrations of ambient and subway air is as small as 0.50 during running hours (6.00-1.00 next morning), wheres it is about 0.80 during suspending hours (2.00-5.00). In comparison with the regulated standard in Japan, the percentage of subway data over it is 30 percent in suspending hours which is equal to that of ambient data, but it is no less than 70-90 percent in running hours. These show that subway air in running hours is more pollutioned than expected.

This paper discusses the general techniques of calculating weighting factors in time series method in the unsteady state heat flow in the air conditioning thermal load calculations. It is shown first that the weighting factors WX_j relating space cooling load to heat gain of surface heat flow, can be obtained by solving simultaceous equations, taking account of radiation exchange among the surfaces of enclosed space including the effect of radiation absorption and emmission by water vapor in the space. Then the thermal characteristics of WX_j factors and the calculation techniques of weighting factors relating space cooling load to various heat gains using WX_j factors are described. Finally it is pointed out that the space heat extraction is to be affected remarkably by WX_j, particularly in the case of intermittent operation of air conditioning.

In this paper, pedestrian's space notation of a total area of Umeda-underground-center is investigated. The notation is identified with a map as a schematic pattern of one's behavioral environment, which is named "image map". We derived, from each of 38 testees, the image-map and some comments of his behavioral act. On these maps the basic concept and their behavioral meanings are stated. They must be useful for establishment of safety scheme for an emergency in the underground passage-ways area and others. Results obtained are summarized as follows, (I) Drawn contents of maps are adherently related to the usual behavioral act of pedestrians. So the difference of image-maps from the real geographical map is remarkable. Base map for the safety scheme must consist with the public image of the space notation. (2) Generaly, drawing act of each map is started from the place or faclities through which the testee has entered to the underground-center. (3) A passage-way lains east and west means a main axis in space notation and other ways consist with branches which are derived from the axis. It is probably true that this is the basic struture. (public image) of the notation. (4) The notation of the underground area does not accord with the notation of places and facilities above the ground. It seems to be probable that the inflexible behavior in an emergency are strengthened by this isolation.

(1) The buddist halls in the Kamakura period are closely related with the diameter of columns in the chancell Area and the building Area as well as the Heian period, but it is not a strictly meaning on the study. (2) In the relation of φ and bay, there is the closest correlation between φ_<out> (the diameter of column in the aisle) and the middle bay toward wide. Although this is not a strictly correlation on the study. (3) In the relation with φ_<in> and φ_<out>, we have not only a close correlation in the Kamakura period but also the Heian period. and its relation is compane with the correlation of the Zen style in the Breath of straighting belt. (4) In the relation of bay and bay, we shall beabl to have a close correlation as well as the relation in the Zen style.

The origin of the Amidado (a hall for worship of Amida) is usually attributed to the Jogyodo. But I think these have different sources. If we compare the figures enshrined in the two halls and the form of the two plans, we can observe distinct differences. The Jogyodo always belonged to the temple, and was the place where public events were held, while the Amidado was the place for private prayer. In proportion to the increase of the believers of the Jodokyo, a new form of belief was born and in accordance with it, a new form of architecture was invented. This was the Amidado.
