    In this paper, such results are reported. (1) There is remarkable difference in the volume change of concrete between the JIS (Japanese Industrial Standard) test pieces (10×10×40cm, cured at 20±3℃, 45±5% R. H.) and the test pieces cured in field. The latter is 1/2 or 1/3 of the former. (2) There is also difference in the volume change of concrete in full-scale rahmen cured in field among each part. At the full wall rahmen, the volume change in under ground beam is smaller than 1/10 of that in the other parts. (3) In eight meteorological data (atomospheric pressure, temperature of the air, vapour pressure, relative humidity, wind velocity, amount of cloud, amount of precipitation and time of sunshine), the varirtion of temperature of the air is more effective than the others on the variation of volume change at small interval (one day). (4) Consequently, the cracking of concrete is caused by the variation of temperature of the air as well as shrinkage of concrete.

    In slip form the supply system from trasit mixers to forms was very complicated and concrete was used to segregated on the way. Recently concrete pump was introduced in slip form, we used effectively concrete pump and improved the supply system of concrete and saved workmen. In this paper, we present 3 examples of the improved supply system of concrete. In the first example the distributor, which revolves at the top of the vertical main pipe and is installed the rubber hose for supplying concrete, easily pours concrete at the optional place. In the second one there are exits of concrete on the way of the transit pipe. In the last one transited concrete is shared with the right floor hopper and the left floor hopper. We believe that these systems can't be settled in one pattern, so we must find the best system at every construction work.

    In this paper, the auther studies on fire damages caused by thermal stresses at reinforced concrete frames and steel frames. It is assumed that the heating condition for the reinforced concrete beams is corresponding to the second class heating of JIS A 1304 and steel beams are heated at 300℃. The thermal stresses at the columns of the both sides of heated beams and at heated beams, in both cases, are much more over than the calculated stresses of these members by usual method.

    Dynamic earthquake proofness of a vibrating body in the atmosphere can be evaluated by the state of attenuation of the free vibration of the vibrating body. This study deals with the actual measurement of the values of the attenuation coefficent of vibration due to atmospheric resistance which consists the principal cause of this attenuation on the theoretical reduced scale models which have relations with various shapes, states of vibration (periodic times, amplitudes, vibration curves, etc.), as well as masses and volumes (or the direction of the vibration and projection area). And the results obtained are arranged on this paper.

    Generally steel portal frames carry vertical load, for instance of dead load and snow load on the roof, and horizontal load, for instance of earthquake and wind. Then bending moment of the members grow bigger at corner crossed beam and column, result in strengh of whole frame is almost fixed by rigidity of the corner knee members. Especially in case of truss structure of that rigidity out of loading plane is extiemely weak compared with rigidity in plane, how to brace the truss members become the most important point. In effect truss structures have certainly bracing members (for instance of purins and furring strips) at the outer cord member, but at the inner cord member often no bracing members. Then if the inner cord member carries compressive axial load, it is in danger of laterally jumping out before attaining to prearranged strength. Truss member of large depth come into question of influence on strength and differection by bracing members, and whether the bracing member at the outer cord member take effect for jumping out of inner cord member. For explaining these question, we made an experiment on lateral buckling of knee members of truss structure composed by angle and pipe sections.

    In previous papers reported in Transactions of A.I.J., No.154, in Dec. 1968 and No.155, in Jan. 1969, a specimen for the welded steel trusses, in which T-structural shape for their chord members, steel tube for their web members and eccentric panel points to make the construction of their panel points as simple as possible were adapted, was tested to find its strength and rigidity under a concentrated load acting on its middle panel point to make its loading symmetrical. And the results of the test were discussed in comparison with the results of the elastic and plastic analysis. As the results the elastic and plastic behaviors of the specimen in the test were found to nearly satisfy the results of the theoretical analysis. In this paper the same specimen as the previous papers is tested to find its strength and rigidity under two concentrated loads, which act on its upper chord members except eccentric panel points to make its loading symmetrical. And the results of this test are discussed in comparison with the results of the elastic and plastic analysis based on the same method as the previous papers. the results are as follows. (1) The yield load of the specimen in this test was 23.7 tons and the rigidities of the specimen for larger loads than the yield one were nearly equal to zero. Therefore its yield load was found to correspond to its breaking load due to the local buckling, which occurred in the web plate of the T-structural shape on the middle eccentric panel point. And the yield load of the specimen was found to nearly satisfy that of the theoretical analysis, on the other hand the deformations of the specimen corresponding to loads near its yield one were slightly larger than those of the theoretical analysis. Therefore the accurary of this theoretical analysis was found to be better in the loading like the previous papers than in that like this paper. (2) The dameges to the panel points of the specimen could not be observed until its breaking load.

    This paper is one of the completion for the consistent research including the released reports on the main and local meetings of A.I.J. This is the examination for the problems of using sanitary fixtures as the fundamentals for the sanitary equipment design, piping design and calculation of the volume of use water or the optimum numbers of fixtures. At first, it is suggested that there are some undeveloped parameters, and necessities to keep on inevestigation regularly and minutely. And then, it is suggested the analysis for the simultaneous use of sanitary fixtures. For that problem, conventional reports were all some of the investigatives or theoreticals, and there was no experimental method. This report is suggested the new experimental method, and the results of analyzing by this method. The results is saggested that the distribution of the numbers of simultaneous use approximates the poisson distribution (see Fig.4〜8), and the case of multi stories simultaneous use corrects error of the conventional value (see Fig.11〜15).

    One of the most important data for planning wards is to know where and how the patients do their activities of daily life (ADL), such as washing, excreting, bathing etc. In this paper, we investigated the places of ADL dividing in to three parts, i.e. (1) in the bed (2) out of the bed in the ward (3) out of the ward, and the way to the places from two different points of view, i.e., (1) with supporter or not, (2) with supporting apparatus or not, if they use it, what kinds of. CONCLUSIONS (A) Places for ADL (1) Out of the ward : Almost all of ADL are held out of the ward (50%〜98%). Above all, bathing is usually held out of the ward in every kind of facility (over 95%). For the bath room in the special treatment facility for the aged, the special equipments are well designed. (2) In the ward : 30〜50% patients in hospitals are washing faces and excreting in the ward. In one of the hospitals investigated 50% patients are taking the bath on beds by a kind of movable steam towel apparatus. (3) In the bed : Remarkable percentages (35〜45%) are found in their excreting. They use pots in the bed or chairs with a pot by the bed. (B) Supporters In every facilities, we found out 40〜80% patients moving with supporters, espicially, in disabled children's facilities, as well as in the ward for pediatrics, childbirth, or plastic surgery of the hospitals. (C) Supporting apparatus In disabled children's facilities, 60% children role out of the ward through the flat corridor covered with carpet, and 25% children use wheel chairs. As for the old people's houses, those are typical cases that they go to washing with canes, and to bathing on stretchers (54%).

    The artitectural materials on the structure of the windows and the doors and the stonework of the part of the KAITAKUSHI at Tokyo completed in the early years of the eighteen-eighties are introduced and then discussed. Main matters studied here as follows; (i) the fact that there was the critique that the designs of the details of this building were not fit for the Japanese climatic environment which were often visited by a heavy rain and a gale. (ii) the supply condition of stone at Tokyo in the construction time.
