In this paper, We examined the impulsive force characteristics of the heavy impact source stipulated by JIS A 1418, and measured the impulsive force characteristics of the jumping down of the adults and children. It is said that the impulsive force of the heavy impact source stipulated by JIS A 1418 is too large for the measurement of the wooden floor construction. When the falling height of the heavy impact source becomes lower, the impulsive force decreases and the impact time increases gradually. As the results of the theoretical and the experimental examination, it can be said that the falling height of the heavy impact source should be kept more than about 20 cm, for getting the linearity of the impulsive force characterisics to JIS A 1418. In the field measurement, the relation between the impulsive force for the various falling height of the heavy impact source and the vibration velocity of the several kind of floor construction was studied.

When the visual environments are to be evaluated correctly the most essential point to bring conditions of evaluation close to worker's acutual situation is to introduce the movement of worker's sight line and the ensuing change of his adaptation luminance in conditions. To realize above, authors have been studying the dynamic evaluation of the visual environment and this paper is a part of it's program. Authors have suggested the method of the dynamic evaluation for discomfort glare after clearing the irrationality of the conventional assumptions that worker's sight line is always fixed and his eye always perfectly adapted to the luminance of his visual field. First, in the case of uniform luminance field, the evaluations of discomfort glare obtained by three subjects under both perfectly adapted condition and transition stage of adaptation are compared and discussed. The results make it clear that there are striking differences in discomfort glare sensations between both conditions of which luminances are equal. Authors propose the method to evaluate discomfort glare dynamically from three factors which are pre-adaptation luminance (L_1), the field luminance to be evaluated (L_2) and the time after the luminance change from L_1 to L_2 (T). Secondly, the method to deal with non-uniform field is investigated and the figures are proposed which give the luminance of the equivalent uniform field to the single glare source on the sight line as to the discomfort glare. Using two figures in combination, it can be obtained the worker's dynamic discomfort glare sensetion which he really feels, when he moves his sight line from his working planes to a glare source. It must be noted that the figures here presented are based on the data from only three subjects. For the use of practical evaluation, another figures must be prepared using sufficient number of subjects. Finally, referring to our results, the discomfort glare formula presented by Conell University in USA is examined and it's irrationality is pointed out.

The purpose of this paper is to report the foundmental data for the pressure loss at the openning of wall surface when wind flows near the wall surface. In this paper, we describe the wind tunnel invesitigation into the property of the pressure loss at the openning of wall surface of model in a simulated atomospheric boundary layer. The results are surmmarized as follows. 1) With increasing of down-flow near the wall surface, the pressure loss at the openning of wall surface gets bigger as the thickness of turbulent boundary layer gets thinner. 2) When a low model is placed upwind of tall model, with increasing of wall wind pressure, the pressure loss at the openning of wall surface gets smaller and with increasing of down-flow near the wall surface, the pressure loss at the openning of wall surface gets bigger. 3) The correlation between the pressure loss at the openning of wall surface and mean wind velocity near the wall surface is observed. 4) The correlation between the pressure loss at the openning of wall surface and the wall wind pressure is observed.

In this paper we describe a simplified calculation model of vertical air temperature distribution during heating in the air-conditioned room, where air supply outlets are installed in the ceiling or the high sidewall and air return intake is installed in the low sidewall. The basic equations for the calculation are derived from a mixing process model of the room air, which is divided into complete mixing region at the upper side of the room and piston flow region at the lower side of one. It is assumed that in the former the discharged warm air is mixed with the room air completely, while in the latter the room air moves downward to the floor and its temperature gradient is formed only in the vertical direction of the room. Regression equations were derived from many experimental results for stepwise inputs of warmed air at the simulated full-scale office room. The equations give relation between the model parameter defined as a ratio of depth of the complete mixing region to the room height and Archimedes number which is induced from the supply air condition.

In the previous paper., the correlational analogy method, in which we find an associational relation between two assignmemts in plan, was proposed in order to assist design process. In this paper, we discuss statistical fundamentals on the finding method of associational relationships. Furthermore, we propose a method keeping the consistency of the architectural knowledge-base. The associational relationship (A, B) means that the two assignments A and B occur coincidentally in many plans. Then, we can use the statistical testing method as a criterion of judgement whether the relationship is meaningful or not. That is, we can find only meaningful associational relationship between two assignments using the fact that a random variable defined by correlation coefficient between two assignments has a t-distribution. Although associational relationships passed the statistical test, it is not always to keep the consistency in the logical relations among relationships. For example, when relatinships (A, B), (B, not C) and (A, C) have been passed, the first two relationships infer a relationship (A, not C) which contradicts the third relationship (A, C). We discussed this problem using the graph theory, and find a fact that if the graph expressing the associational relationships is "a balanced graph" then there is no contradiction among the associational relationships. Then we propose a method keeping the consistency by using this fact.

As the second series of studies on the Italian "PIAZZA", this paper discusses the relation between "PIAZZA" and the surrounding buildings from the visual structure. The analysis focuses on the relation of visual attributes; the distance of discrimination, the horizontal angle (W/D), the angle of elevation (D/H), to grasp the quality of the space of the Italian "PIAZZA" and to define the meaning of visual points. This study confirms the following: 1) The significant public building can be perceived from the "PIAZZA" edge within the scope of "BINOKULARES BLICKFELD". 2) The visual point "N" , which depends on the emplacement of the significant public building in the "PIAZZA", can be regarded as the substitution of the centroid "G". 3) The distance of discrimination between the visual point "N" and the significant public building is for the most part within 100 metres. 4) The average ratio (D/H), which investigated in the 72 directions to grasp the impression of the closed space, is about 2.3. From the SPREIREGEN's theory of "D/H", this should suggest that the Italian "PIAZZA" makes the comfortable and restful impression on the viewer.

This study discusses on the significance of Yokohama Municipal Apartment Houses and the Influence upon Tokyo Municipal Apartment houses. Conculusion as follows; (1) Yokohama Municipal office carried out the project of municipal apartment house positively and intended to build the apartment house as the model of housing improvement in japan. Yokohama municipal office thaught that the ideal municipal apartment house was an apartment house with shop in urban district. Yokohama municipal office built four minicipal apartment houses before the Kanto Earthquake of 1923 and realized the ideal apartment houses. These apartment houses were built to solve the housing shortage of unmarried persons and low salaried men. (2) Before the Kanto Earthquake of 1923, there were no municipal apartment houses in Osaka city, Nagoya city, Kobe city and Kyoto city. In Tokyo city, four municipal apartment houses were built before the Kanto Earthquake of 1923. However Yokohama municipal apartment houses were built earlier than Tokyo municipal apartment houses. Then Yokohama municipal apartment houses were progressive project in the age. (3) Tokyo municipal office inspected Yokohama municipal apartment houses. After the inspection Tokyo municipal office changed the project of municipal housing and desided to build an apartment house. The structure system and the builder of Tokyo municipal apartment houses were same as Yokohama municipal apartment houses. Yokohama municipal apartment houses influenced directly Tokyo municipal apartment houses.
