    It has been Known experimentally that the Strength and rigidity of welded steel trusses of tubtlar construction will often be decreased by the local deformations taken placed at the panel points. Therefore in order to make these local deformations as small as possible and to utilize the merits in the structural shape-trusses, the authers devise a welded steel truss in which the T-structural shape (half the H-structural shape) is adopted for the chord members and the steel tube for the web members. In this paper a type of the above mentioned welded steel truss is treated, in which the panel points are constructed of the eccentric panel points to make the construction of chord and web members at the panel points as simple as possible. Two specimens are tested for finding their strength and rigidity under the vertical loading at the eccentric panel point, and the results of these tests are compared with the theoretical analysis for the welded steel truss with eccentric panel points. The results are as follows. 1) In the test both specimens of the welded steel truss with eccentric panel points showed nearly the same elastic and plastic behaviors respectively. The elastic behaviors were found to satisfy most of the results of the theoretical analysis and the plastic behaviors were qualitatively explained by using the simple plastic theory. 2) The damages to the panel points in these specimens could not be observed until their breaking loads. 3) The maximum loads (13.90 tons and 13.82 tons) of these specimens were about 4.38 times their allowable load (3.16 tons) in the short time loading used in the structural design and were about 1.78 times the allowable load (7.77 tons) of the truss which has the same members and size and has the non-eccentric panel points constructed of pin joints.

    In order to study the wind pressure distributions and the response of a suspended roof due to turbulence, model experiments were made in wind tunnel. The model used in tests had a size of 41×31cm, a height of 18cm and roofed by a soft vinyl membrane. In measurement of the wind pressure distributions, the wind velocity was about 22m/sec and 28m/sec. On the other hand, fluctuating wind forces and vibrations of the roof were measured under the wind velocity 13.5, 17.5 and 21.5m/sec, in five different directions relative to the model. Fig.2 to 8 show the the wind pressure coefficients obtained by the tests. Fig.9 and 10 show a part of fluctuating wind force records and vibration records of the roof. Displacements of the membrane are shown in Fig.11 and 12. It will be important to make clear the relation between the fluctuating wind force and the vibration of the membrane, and also the dynamical characteristics of actual roofs in future study.

    This paper describes matrix analysis by the slope deflection method and solution by the moment distribution method of multi-story multi-bay rigid knee-braced bents and braced bents by using the digital computer. It discusses how the solution by the moment distribution method is more advantageous than matrix analysis due to the fact that storage and running time may be reduced and that processing of irregular structures can be done easily. (The more irregular the structure, the more reduction in storage and running time.) Moreover, in the moment distribution method, the routine of distribution and carry-over of fixed-end moments governs the storage and time. This paper shows the computing techniques on how such storage and time should be reduced, giving examples using the IBM 7090. Moreover, in the examples, both cases, considering and not considering deformation due to axial forces have been compared.

    The length of stay and the disease cohort of in-patients-age, sex, and ambulant status distribution and illness types etc. -are the significant factors in the planning of the hospital building. This paper is a report of the field studies on the length of stay and disease cohort of in-patients. Some of the results of the studies are as follows. (1) From the analysis of momentary length of stay the patient could be classified into two groups-long term patient (spinale lesion, silicosis pulmonary and grane fractures) and short term patients (other medical and surgical diseases). The increase of long term patients means the decrease turn-over rate of hospital beds. (2) I made investigations on age, sex, and ambulant status distribution of in-patients. The influence of those factors will be great on the planning of bed areas, day spaces and especially avcillaries (W.C.'S, wash basins and batling facilities. etc) in ward units. (3) At the orthopedics ward units I found more numbers of wheel-chairs in use than any othere. Therefor, Orthopedci ward units require more space for the effectine use of wheel-chairs.

    This report, continued from the preceding paper, is our redevelopment plan and design, consisting of next part, 1. Introduction 2. Characteristics of the district 3. Principles of redevelopment plan 4. Design We planned to make a new street through the central zone in addition to present kawaramachi street, and proposed to rebuild and modernize by many super buildings instead of small wooden houses, according to three stepped execution plan, as illustrated in this paper.

    This report (II) continues the report (I). In the report (II) analyses of trends and analyses of cross sections are treated. To be spoker specially is next. It is to make clear a meaning on the patterns of cross sections. That is to say, it was found that there are some relations between characters of region and patterns of sections.

    Although many investigations on the works and painters of fresco has been done, little is known about the regulation of "Price of paintings". This is the description of the price of fresco which has been regulated by the subject and size of painting, according to the data of official painters under the Tokugawa Shogunate, and of "Price of paintings" in building Kyoto Imperial Palace. The conclusion is as follows, A. "Price of paintings" had been regulated by i) the subject (figures, birds, flowers and other natural beauties) ii) size (the unit is one "tsubo" of six or six and a half "shaku") iii) the art of painting (high colored, rag pasted, "sumie", etc.) iv) the classes of painters (30 per cent premium is the case of "Hoin", 20 per cent, "Hofuku") v) the genealogy of painters "Okueshi", "Omoteeshi" etc.) B. The regulation had been adopted in the case of i) the buildings under direct control of the Shogunate ii) the official painters of Shogunate, especially the Kano School
