This paper describes the field tests which were carried out for purpose of getting technical data and confirming the theory on the pumping pressure presented in Part 1. The synthetic lightweight aggregate concrete and the ordinary concrete of various mix proportions were pumped through the pipelines with diameters of 2", 3", 4", 5" and 6". The pressure of concrete in pipelines was measured at several points and pumping speed was also obtained by measuring the flux of concrete at the discharge end. Three kinds of squeeze-type pump and one kind of piston-type pump were used. The maximum length of the vertical and horizontal pipeline were 30m and 54m resectively. The results were as follows : (1) The adequacy of the theory presented in Part 1 was confirmed. (2) The distance that concrete can be pumped varies with the capacity of pump, the diameter of the pipe, type of aggregate, mix proportion, the flow speed of concrete in the pipe and other factors. (3) The technical data were obtained by which pumpability of concrete under various conditions at job site can be estimated.

For investigating how a high-rise building will be displaced in response to the wind pressure fluctuation, the wind velocity above the Kasumigaseki Building was registered by an anemometer of pitot-differential potentiometer type set at the scaffold built up 10m high on the penthouse during Typhoon No.22, 1967, while the long and short components of the vibration of the building were respectively measured by the vibrogaphs set on the 35th, 21st and 12th floor and the plumment of piano wire about 100m long suspended from the roof to the 13th floor in the staircase under construction. Then, from the power spectral density of the wind fluctuation, the maximum displacement of the building was theoretically calculated as one-mass system and multi-mass system and found in good agreement with the measured value. In short, the long components of the vibrations of a tall building are random and caused by gusts of wind, with the fundamental mode, while its short components are negligibly small as compared with the long ones, though they are rather regular of natural frequencies with the fundamental mode.

In the previous paper, we have reported about a theoretical study of columns joint in different diameter steel-pipe columns under normal force and uniform moment. This paper is experimental study of joint. Test specimens are different diameter steel-pipe short columns welded with joint ring. We add axual load and eccentric load to them. And we compare strain distributions and elastic deformations of them with theoretical values. In consequence, theoretical values approximate experimental them.

Some formulate for computing the direct daylight factors which are attributable to source surfaces of a rectangular and a right-angled triangle shape in vertical and horizontal positions were introduced by the authors in the paper of the previous issue of this Transactions. The formulae are derived on the assumption that the luminance of source surface is so distributed that B(θ)=B_Z(1+2sinθ)/3, where θ is the altitude of that part of the source surfaces where the luminance equals B(θ) and B_Z is the luminance identical with π/2. The present formulae are more complex, and therefore the calculation more tedious, than those derived on the assumption of uniform luminance. The authors have worked out some computing diagrams for convenience of calculation. The diagrams for vertical plane of illumination are given in this paper (Fig. 1). The examples of application are shown in Table-1 on Page 63, together with the symbols used in the diagrams. As an example of application, the authors have calculated the distribution of direct vertical daylight factors on the horizorital plane illuminated by vertical source surface of rectangular shapes. For convenience sake they have also another calculation of the formula to be applied in this example. Simplified results are given in Table-3, 4 on page 71. 72.

This research report consists of four sections : report (I) which has already presented in the preceding number and report (II) which is presental here and report (III), (IV) which will be presented in the next numbers. In report (I), (II), (III) we describe about the measurement of the velocity of the wind near the building wall and the velocity in the corridor opened to the outdoor which is set on the exterior wall of the building. In this experiment, we use the single model of the apartment house and a few models arranged variously, 24 hot wire anemometers are set on the wall of the model. Report (I), (II), (III) aim at reaching some principles for setting the balanced-flre terminals and another principles for designing the corrider opened to the outdoor. In report, (IV), we describe about the analysis of the turbulence of the air flow around the bluff body on the building wall and the analysis of the surface pressure of the wall, In this experiment, we use the two dimensional fence model and block model on the flat plate and the various kinds of electronic instruments, for example, linearizer, correaltor, A-D convertor, analogue and digtal computers, etc. Report (IV), aim to clarify the diffusion of the exhaust of the gas boiler around the bluff body on the building wall and to reach some principles for deciding the position of the balanced-flue terminals which is set near the bluff body.

We have investigated the traffic to medical and surgical wards to get the fundamental idea for estimation of the number of elevator in hospital ward. The results are as follows : (1) There are about 7〜8 movements to each ward per bed per day. that is- nurses 2.0〜2.5 times doctors 1., 〜1.5 times other staffs 〜1.0〜 times patients 〜1.0〜 times visitors 2.0〜2.0 times total 7.0〜8.0 times (2) The number of traffic to and from ward by stretchers, wheel chairs and carts per day is a third of number of beds. (3) Peak traffic periods are 9 : 00 to 10 : 00, 13 : 00 to 14 : 00 and 15 : 30 to 16 : 30. But fluctuation of traffic to the ward is not so remarkable. The highest peak is made by visitors during visiting hour.

As the density in urban district grow higher, sunshiny conditions become worse and worse everywhere. The obstruction of sunshine means not only the decrease of sunlight into houses, but also the reduction of "Opening", and thus the dwelling conditions (sunshine, ventilation, view, privacy, safety and so on) get worse. In order to make functions of sunshiny conditions on life clear, we examined sunshiny effects in different housing levels. The functions we examined are : comfort of environmental climate in summer and in winter, drying up of washing and bedclothes, sunbath of babies, gardening and lightness. The results are as followes. (1) The lower the housing level is, the worse the sunshiny conditions becomes, and so the dwelling space gets very poor. (2) Orientation of houses brings great difference to the dwelling conditions. (3) Balconies are very useful in apartment houses. (4) In order to improve dwelling conditions in urban district, the progress of getting high-density must be stopped.

The purpose of this thesis is to clarify a physical characteristics of the mixed area of residence and industry as a parameter for the planning in a case of both redevelopment and reallocation of residence and industry within the same area. It is almost imposible to move the small scale factories out of the existing area. Because, they have a deep relationship among them and, moreaver, they lack the budget for moving to an industrial area. The six districts (approximately one square kilometer) are selected as a sample from the Tokyo metropolitam Region. They are actually surveyed and analysed according to road area, building area, floor area, openspace, mean number of stories and building use. All items are estimated by a mesh analysis. In this case, a size of each mesh is 5 meters by 5 meters.
