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.

既論では, 剛節トラス(弦材 : T形鋼, 腹材 : 鋼管)のなかでその節点構成の最も簡単な偏心節点をもつ剛節トラス(図-1)について, その上弦材中央節点部載荷時における耐力と剛性とに関する実験を行ない, この結果をトラスの二次応力をも考慮した剛節トラスの弾塑性解析法(トラスとしての特殊性を考慮したある仮定にもとずく塑性ヒンジ理論)と対比したところ, 弾性域から弾塑性域をへて破壊荷重にいたるまでの性状は, この理論解析方法で比較的よく説明しえられることが知られた。本文は, 既論につづくもので, 既論と同様な偏心剛節トラス(図-1)について, その上弦材に中間荷重が作用する場合における耐力と剛性とに関する実験的研究を行ない, これらの結果を, トラスとしての特殊性(トラスでは一次応力は軸力であり, 曲げは二次応力)を考慮した既論と同様な仮定, すなわち, 仮定1 : 部材の応力度一歪度関係を完全弾塑性の二直線とする。仮定2 : 部材の降伏曲線を求めるに当り, 軸力と曲げのみを考慮し, せん断の影響は無視する。仮定3 : 部材において塑性ヒンジの形成個所以外は弾性とし, かつ部材の変形にともなう軸力による付加曲げモーメントの影響は無視する。仮定4 : トラスの荷重が増大している場合, ある荷重(P)のもとである部材の一部分に塑性ヒンジが形成されるとき, その荷重以上の増分荷重(&lrtri;P)に対して, すでに形成されている塑性ヒンジは, その増分荷重に対応する軸力の増分(&lrtri;N)によりその部材の降伏曲線を満足するようその負担曲げモーメントが変化(&lrtri;M)する塑性ヒンジとする。仮定5 : トラスの荷重が増大している場合, ある荷重(P)のもとである部材が引張軸力N(圧縮軸力)と曲げモーメントMにより全長にわたり降伏するとき, その荷重以上の増分荷重(&lrtri;P)に対して, この部材は, その全断面積(A)のなかで圧縮応力度(引張応力度)のみが作用している断面積(&lrtri;A)のみが増分引張軸力&lrtri;N(増分圧縮軸力)に対して弾性として作用し, その部材の両端に仮定4を満足するような塑性ヒンジをもつ部材とする。を用いた弾塑性解析と対比し, 図-1のごとき荷重状態における偏心剛節トラスの弾塑性性状を究明するとともに上記剛節トラスの弾塑性解析法の妥当性をも検討したものである。

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).

General performance of building element construction is considered available to determine building element construction. It is necessary to unify every performance unit and to clarify performance weighting coefficient. This study aim at seeking the said performance weighting coefficient. This paper, Part 1, refers to both the abstract of the study and the process of preparing the data necessary for the study.

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.
