    Ordinary types of column bases, which are usually encountered in small steel buildings, consist of anchor bolts embeded in a concrete footing and a base plate not covered by reinforced concrete. This paper deals with theoretical estimation of the ultimate strength for these types of column bases. In this paper the tensile strength of anchor bolts and the flexural strength of a base plate are chosen for the parameters governing the column base strength. The column base subjected to a bending moment and an axial force is substituted by a simple mechanical model. Then a rational solution for the interaction surface of flexural and axial resistances in the column base is presented through the upper and lower bound theorems in the limit analysis. The solution is compared with the maximum strength observed in past experimental results, and proved to provide satisfactory predictions. 1) Research Associate, Institute of Industrial Science, University of Tokyo 2) Professor, Institute of Industrial Science, University of Tokyo

    In order to clarify the mechanism of stress transfer developed through the connection in steel column bases, this paper reports an experimental study on the relation between load and strain, and the stress distribution characteristics in column base connections based on the experimental data which was already presented in the previous paper (Part 2). The main results derived from the analysis on these experiments are as following : (1) From the strain distribution characteristics of the mortar footing, it is confirmed that the reaction distribution and available area compressed on the surface of mortar footing are influenced predominantly by the change of thickness of the base plate. (2) In the bending stress for the cantilever part of base plate, the calculated values of the analysis and institute are in accordances approximately with the experimental results in the tension side. In the compression side, the calculated values of the analysis and institute are in good accordances with the experimental results in the case of a thick base plate, but in case that the base plate come to be thin, the calculated values of the institute are overestimated in comparison with the experimental results. (3) On the tensile reaction produced to the anchor bolts, the correspondence of the experimental results to the analytical results is good nearly, but in case that the base plate come to be extremely thin and the eccentricity come to be large, the calculated values of the institute are underestimated in comparison with the experimental results.

    The techniques of discrete field mechanics are used in conjunction with energy method to obtain an exact mathematical model to represent a latticed shell subjected a flexure and corresponding solutions. The method developed is considered as a kind of micro approach and its usefulness has proven especially effective for the analysis of latticed shells with general types of boundary supports, such as free or ribbed polygonal edges. The immediate results are; (a) The mathematical model which can be used for the linear analysis of latticed structures (b) A clear statement of the natural boundary conditions associated with each system (c) Closed form solutions to the total model described by the steps (a) and (b) A further development of the method enables one to obtain with relative ease closed from solutions to structures which were not amenable by conventional method because of the complexity of the boundary conditions. Such solutions are valid over the entire structure and are independent of the size of the system. The technique is applied to the solutions of circular cylindrical latticed shells with ribbed polygonal edge beams, where rigidities of the beams can take arbitrary values. Each solution presented in this paper has been investigated numerically and compared with results obtained by open form method. The comparison shows significant accuracy and great reliability of the technique proposed here.

    バイリニア型履歴特性をもつ2自由度系に, 定常ホワイトノイズが作用したときの, 各層の塑性エネルギー配分に注目した。下層のエネルギーの比率ε_1に影響を与えるパラメーターは, 質量比μ, 剛性比κ, 塑性剛性比γ_i, 強度比βおよび無次元入力強度ξである。このうち, μは常に1とし, γ_iとξも大半は1/(10)に固定された。残るパラメーターはκとβである。ε_1-β曲線が広い範囲のκに対して作成され, その特性が検討された。その結果によれば, ε_1に対してひときわ強いパラメーターはβである。特に, 無次元累積塑性変形λ_iの比νが1に近いところでは, βが少し変わってもε_1は大きく変化する。ν=1を最適設計の規範とすると, 実際のβの評価には高い精度が必要である。又, 最適なβとε_1又はκとの関係が近似的に導かれ, 数値実験値とよく対応することが示された。ここでは, 質量比μの役割は無視されているが, その影響も調べる必要があろう。これは将来の仕事である。

    This paper follows the author's preceeding two papers : dynamic characteristics of a structure with buried foundation (1) and (2). In this paper are considered dynamic interaction characteristics of structures embeded in a perfectly elastic layer medium over a half-space when subjected to horizontal base rock motion. In Sec. 2 is derived the set of governing equation on soil-structures interaction system subjected to base rock motin. In Sec. 3 are derived the analytical expressions of the sway and the rotational spring constants of sub-side soil ground when the basement wall vibrates horizontaly or rotationally by taking account of the adjacent basement one. In Sec. 4 are derived the analytical solutions of the dynamic wave pressure which operates on the basement wall subjected to horizontal base rock motion.

    A vibration test of a 180 meter high reinforced concrete stack was conducted by means of human excitation forces at the top, and then by a vibrator at the base mat. The MIK measuring system was applied to obtain resonance curves, resonance periods and mode shapes. The information obtained was investigated from the view point of identifying a vibration system for performing simulation analysis. Based on several findings that the base mat deformations were not so negligible as assumed and that modal damping of the 1st and the 2nd mode were equally small (0.8%), when compared with that of the 3rd mode (more than 20%) where the sway of base mat is predominant, the vibration model used in design analysis was modified so as to simulate the tested behaviors. Frequency dependent patterns of the base mat deformation were calculated using newly proposed analysis method for dynamic soil-structure interaction and compared with the test results which proved to have reasonable agreement.

    This is an analytical investigation about bi-axial and uni-axial restoring force characteristics of the same reinforced concrete section. Restoring force-accumulated plastic deformation relation, hysteretic energy absorption capacity and the ductility of the section were compared between the case that the section was under bi-axial curvature history and the case that the same section was under uni-axial curvature history. A lot of cases were analyzed with the various parameters. It was found that bi-axial and uni-axial restoring force characteristics of the same section are strongly affected by axial load and that there is a significant difference on the aseismic performance of the reinforced concrete section between the case that the section is under bi-axial curvature history and the case that the same section is under uni-axial curvature history.

    高温引張試験より得られた結果より1)降伏点, 引張強さの低下率は, 高力ボルト接合部構成材中唯一の非調質材であるSS41が, 他3材に比べ異った変化を示す。すなわち, 熱処理された調質材(ボルト・ナット・座金)は, 焼戻し温度を越える範囲で急激な低下を示すのに対し, SS41材は, 低下率の変化はほとんどない。2)各材のヤング率は, 同一温度ではほぼ同じ値となる。3)高力ボルト材の降伏強度, 引張強さの低下率は, 焼戻し温度の低い順, すなわち, F11T (415℃)が最も大きく, ついでF10T (460℃), F8T (490℃)の順となる。リラクゼーション試験で得られた結果より1)SS41は, 一般的に他の調質材に比べて応力低下率が大きく, 特に低温域(250〜300℃)においてこの傾向が著しくなる。2)ボルト材は, 調質材の中では350℃以上のほとんどの温度域において応力低下率が最も大きく, 特にF11Tの応力低下率は, 4時間後には400℃で初応力の46%, 450℃で66%にもなる。

    1)反射ルーバーの効果を実験的に確かめるためには, 事務所建築の中間階を想定した縮尺1/15の模型室を製作し, 窓面に反射ルーバーを設けた場合と設けない場合について室内照度を比較検討し, 併せてその測定方法を示した。2)自然条件のもとで実験を行う場合, 直接的に直射日光率を測定することは不可能であるので, 快晴時及び曇天時における測定値から直射日光率を推定する方法を示した。この方法によれば, 反射ルーバーのような直射日光利用装置ばかりでなく, 従来の窓面による直射日光率を実験的に推定することが可能である。3)反射ルーバーを設けた場合と設けない場合についての実験値から直射日光率を推定し, その値を比較した結果, 今回の実験に用いた模型室の奥の部分で, 反射ルーバーによる効果は十分あることがわかった。また, 反射ルーバーを設けた場合と設けない場合について, 快晴時における室内の様子を観察したが, 反射ルーバーを設けた場合には, 設けない場合に比較してかなり明るくなることがわかった。4)模型室中央線における実験値と計算値を比較した結果, 昼光率は, 傾向が大体において一致したが, 模型室奥の部分でかなりの違いがあった。これは, 実験時における天空輝度分布が影響したためと考えられるが, 更に室内の反射率, 反射ルーバーのスラット面輝度等の推定に誤差があったとも思われる。また, 直射日光率については, 大まかな比較ではあるが, 模型室の奥の部分で, かなりよく一致した。このことから, 反射ルーバーの実質的効果をある程度定量的に表わすことができたと考えている。5)今回の実験で用いた反射ルーバーは, 1/15の縮尺という制約等から, 十分な強度で製作できなかったために, スラットのたるみあるいは風等の影響で, 天井面受照部に乱れを生じたが, これは縮尺を変えて, 反射ルーバーの強度を増せば, 解決できるものと思われる。6)ここで示した測定方法には, 必ず時間的ずれが生じるので, 数多くの実験値を得ることが困難である。そのために, 非常に数少い実験値のみ検討したが, 更に実験方法を改良して, 直射日光を利用した場合における昼光もしくは天気状態の変化が室内照度に及ぼす影響や, 反射ルーバーによって得られる室内照度の時刻的変動について調べていく必要があると考える。

    In consideration of the minimum expected level of sunshine, which was set in the previous paper (Part I), this paper investigates site planning of detached houses. At first, several different types of houses were selected. Then areas of sites, which were needed to satisfy the expected sunshine levels, were calculated according to several various conditions i.e. : degrees of latitude of 32 degrees, 35 degrees and 38 degrees, respectively, a turning angle of 0, 10, 20 and 30 degrees from south, two kinds of street layouts (south-north and east-west), with and without garages. It was not found that one house type is always better than others. As conditions vary, the most favorable house type changes. Accordingly, during the planning of detached houses, we must take various conditions into account in order to produce good housing, with optimum solar conditions.

    This is the second paper of a continual study titled above. In this study, a practical simulation method was employed for presumption of human injury in case of fire cause by a strong earthquake. On the assumption that an earthquake happens in Osaka, process of fire spreading and behavior of evacuees were simultaneously simulated by computer. As the result, it was revealed that there were structural weakness such as a large amount of wooden houses, inflammable objects, narrow roads, shortage of open spaces for evacuees and so forth. And it was forecasted that a lot of people shall die of fire. Then, effectiveness of countermeasures which were effective to protect fire spreading and to help evacuation were examined by the simulator. In result, some effective measures were found.

    In the historical transition of architecture, as we regard it as a cultural phenomenon, we cannot forget the role that re-creation has played in it. Creativity, which is one of the most important factors of the substance of architecture, will be more clearly and thoroughly understood if we try to understand it not only with theory of creation but with theory of re-creation that exists in the process that a creation is experienced, aesthetically accepted and then led to another new creation. The basis of the idea of re-creation is in recognizing re-creation as a frame of aesthetic acceptance of an object. On this basis there are various developments of ideas. We may apply the theory of re-creation thus developed in many ways, for example, in the meaning of the joint construction of a building, in the relations of a client, a designer and a constructor, in problems of the creativity of a user in using a building or in problems of the maintenance and conservation of a building. This report is a basic study of aesthetic acceptance which is the basis of re-creation, and of re-creation as reappearance of originality that follows such aesthetic acceptance.

    It has been supposed that Uto Turret was removed from Uto to the Kumamoto Castle. But it is only a hypothesis. This study aims to clarify this assumption is not True, by the old literary documents. The Uto Turret was originally built by order of the feudal-lord Kiyomasa Kato in the Kumamoto Castle about A.D. 1602, not transferred from Uto. The name of Uto Turret was derived from the offices which installed in it and arround it. In these offices, Kato's feudal government controlled the vassals of ex-feudal-lord Yukinaga Konishi.

    This study is based mainly on the ancient documents of Imperial Household Shinto, and Chinese Classics such as Li-Chi. The most significant ritual for the enthronement of the emperor is Dai-Jo Sai. And the main stage of this event, Daijo Kyu, is a temporary sacred place set in a kind of time and space that is different from that of the ordinary world. Each of the two central pavilions placed in the sacred place is Yuki (or Suki) Shoden. The Shoden is formed of the two rooms named Shitsu and Do. These architectural structures are looked on as proper to Japan. This paper is a study about the form and the function of these two rooms as compared with the systems of ancestral temples in ancient China. In conclusion, it may be said that we can find some Chinese influences on the structures of the Shoden.

    Der 1907 in Munchen gegrundete Deutsche Werkbund ist eine der bedeutensten Organisationen des deutschen Kunstgewerbes. Vor dem I. Weltkrieg spielte in ihm als Theoretiker besonders Hermann Muthesius (1861〜1927) eine groβe Rolle. Seine 1907 gehaltener kritischer Vortrag, der zum sogenannten "Fall Muthesius" fuhrte, forderte entscheidend die Grundung des Werkbundes, und seine "Typisierungs-Idee" entfachte 1914 auf der Kolner Jahresversammlung eine heftige Diskussion. Um die Aktivitat des Werkbundes bis 1914 durch die Vortrage von Muthesius verstandlich zu machen, gliederte sich der Aufsatz in folgende Artikel (Der VIII. Artikel ist um das Wirken von H. Muthesius als Architekt erganzt) : I. Einleitung II. Zur Grundung des Deutscher Werkbundes III. Die Grundung des Deutscher Werkbundes und die Zeit danach IV. H. Muthesius-vom "Typ" zum "Neuen Stil"- V. Die "Typisierung"-Diskussion auf der Kolner Jahresversammlung 1914 VI. Die Werkbundausstellung in Koln VII. Schluβ VIII. Erganzung -der "Architekt" H.
