Reinforced concrete slabs varying in span-thickness ratio, steel percentage, effective depth, aspect ratio and edge restraint conditions were tested under load to failure with the result discussed in this report. There it is noted that the ultimate load-bearing capacity of these structures is overall in reasonably close agreement with the Johansen value obtained from the moment resistance in consideration of concrete tensile strength.

In this paper (Part V), a fundamental new concept of ultimate aseismic structural design is introduced, and its application method is proposed on the basis of the "Resonance-Fatigue-Characteristics" of structural materials and elements discussed on experimentally and analytically in the previous papers (Part I)-(Part IV). The quantitative estimation of ultimate aseismic structural safety is performed by the direct comparison of (General) Resonance-Fatigue-Characteristics of structures (Fig. 10) with Period-Number of Waves-Characteristics of earthquake excitations (Figs. 8, 9), so the index, deterministic value d_s (Eq. 9) or probabilistic value p_s (Eq. 16), is able to be calculated. The purpose of ultimate aseismic structural design is to make such an index maximum.

In the previous paper (Part 2) an equivalent continuous System was proposed as a kinematic model for a framed structure and was able to give a reasonable approximation for the story stress responses that are story shear forces, story axial forces, overturning moments and transverse forces on the beams. The purpose of the present paper is to illustrate how to apply the story stress responses to earthquake resistant design on the steel framed structure and on this basis to show that the equivalent continuous system may be a useful kinematic model for aseismic design. This paper proposed "equivalent cross sectional area" as a measure representing the magnitude of those story stress responses which can be regarded as vectors with four components. The equivalent cross sectional area was used to evaluate the maximum stress sustained in each member of the frame during the course of earthquake excitations. Further a method to proportion member according to the equivalent cross sectional area was so devised as to control the distribution of plastic deformations of members throughout the structure. Two example frames were designed according to this method and seismic responses of these frames were investigated. Although the present method is still insufficient to produce uniform plastic deformations in the structure, the results of the analysis indicate that overturning moments and transverse forces on beams are influencing factors and have to be evaluated in the process of seismic response analysis. From this view point the equivalent continuous system, which represents the story stress responses in a multi-dimensional space, can be an useful kinematic model for the aseismic design.

It is one of the most important problems in earthquake engineering to predict the intensity of future earthquakes from the past available earthquake recording data, as precise earthquake forecasting is difficult in the present stage. The expectancy of maximum earthquake motions in a certain place may be defined by the seismic activity on the base rock and the ground characteristics. In order to clarify this more reliably, it is necessary to investigate the regional distribution or variation of the seismic activity and the characteristics of soil-layers. The expectancy of maximum earthquake motions based on the seismic activity on the base rock by means of Kanai's Formula and Gumbel's Second Asymtotic Distribution was reported in Apr., 1978. This paper deals with the regional distribution of the characteristics of soil-layers in the range of long period (6.0≧T≧2.0sec.) reflecting the deep ground characteristics of fairly large area, using seismic data of strong motion seismographs published by Japan Meteorological Agency. This paper is summarized as follows, (1) The regional distributions of the magnification of soil-layers in the range of long period reflecting the deep ground characteristics are showed in Fig. 6 (a)〜(b) and Appendix II. As a result, the areas where the magnification factor is considered to be high are generally as follows, i) the coast on the Japan Sea in the Tohoku district from the Hokkaido district, ii) the southern area of the Kwanto district from the area of the Kinki district, iii) the southwestern area of the Shikoku district from the Kyushu district. However the above tendency of the regional distribution varies in detail according to the period components of earthquake motions. (2) The relations between the magnitude (M) and the predominant period (T) of earthquake motion (log T=aM+b), and between the maximum amplitude of the vertical and the horizontal components (R_m) are examined. And the regional distributions of coefficients a, b and R_m are indicated in Figs. 11 and Appendix I. From these figures, it is pointedout that the coefficients a, b and R_m are influenced by the soil characteristics as well as the regional distribution of the magnification factor. 3) It is proposed that the expectancy of maximum earthquake motions on the structural base rack with V_s=0.6〜0.8km/sec. can be expressed for the long period (6≥T≤2sec.) as the product of the following three factors i) the expectancy of maximum earthquake motions based on seismic activity on the seismic base rock with V_s=2〜3km/sec., ii) the magnification factor of the standard ground characteristics, and iii) the regional distribution of the quake degree relative to the standard ground. The procedure of estimation in Tokyo is schematically described in Fig. 17. It is necessary to take consideration that the aspect of the final regional distribution of the expectancy of earthquake motions is different from that based on the seismic base rock in following areas, the southern part of the Kinki district, the area from the south-western part of the Kyushu district to the west-southern port of the Shikoku district, the coast area on the Japan Sea in the Tohouk district and so on. In addition, the effects of the soil characteristics in the short period rarge (T≦1.0〜2.0sec.) reflecting the shallow ground characteristics on a small area or the concepiton of the soil profile types should be introduced from the practical point of view.

Nonlinear vibrations which take place in the equations of motion expressed by normal modes are classified into three types here. The method of harmonic balance is applied to analyse periodic solutions of the equations of motion. Then, the nonlinear vibration problems are expressed by algebraic equations which are composed of the Fourier coefficients. The unknowns of the algebraic equations are classified by applying the procedure described in Part 1. Sience the unknowns express the Fourier coefficients that represent nonlinear vibrations, nonlinear vibrations are classified into three types, accompanying type, branching type (1) and branching type (2). Then in order to study the stability of the periodic solutions corresponding to undisturbed motion, a complex eigenvalue problem is derived by applying the method of harmonic balance to the variational equations.

Basic equations are expressed with physical consideration for flow around roofs. These equations are deduced from velocity potential and oscillations of roofs with initial tension as restoring force considering strong interaction between roofs and flow. Modal approach to oscillations decides total circulation together with velocity condition at trailing edge. Then, roof's oscillation is rewritten as a nonlinear differential equation. A periodic solution is obtained by asymptotic expansion method and the existence of solution and its uniqueness condition are examined. A frequency equation is given from condition that roofs and flow are equal in period of oscillations. Its solutions are decided in different domains depending mainly on wind velocity and roof's weight. Two critical velocities are induced on the basis of total potential energy, which is dependent on wind velocity using the solution of frequency equation. The first is a critical velocity where amplitudes become infinite. The second corresponds to velocity of division between two domain, where oscillations alter modes and enegy at a jump. Accuracies of these velocities are examined. Frequency and damping of structure, especially its weight have maked influence on these velocities. There is not the first critical in case of remarkably heavy roofs. Partly using experimental values, these critical velocities are made to correspond to those which reveal the phenomena.

In the west of Osaka city, a number of canals for woods were filled up with earth. On this reclaimed land, many buildings were constructed. Settlements were observed at one of these buildings and 12 ground points around this building. The observed building has 11 stories and the plan 3spans×32spans, whose structure was constructed with reinforced concrete and supported on sandy diluvium. In this paper, results of observed settlements are shown and observed settlements are compared with calculated settlements by equations which introduced in previous paper (part 1). Main conclusions are as follows. 1. A shape of a building settlements were influenced evidently not only loads of a building itself but also loads of earth around a building. 2. Observed settlements are slightly larger than calculated settlements in diluvium. But these twe kinds of settlemnts agree fairly in alluvium. 3. Such as this case that loads of earth and loads of the building overlap, it is effective to use the theory that the coefficient of volume compressibility m_υ and the coefficient of consolidation c_υ are treated to be variables.

This paper describes a development of the basic equations of transient room temperature for multi-room expressed by various indicial responses, which are found out by means of making approximat of heat transfer due to the radiation exchange among room surfaces in the linear form for surface temperatures. The number of unknown variables could be reduced from total number of surfaces to the number of rooms. In this Part 1, the heat equilibrium equations for miscellaneous surfaces are set up and the coefficient matrix for all surface temperatures is induced from these equations.

本研究では幼児の一日の生活の流れの中で最も行為の重複が現われている食事から午睡に焦点を絞り, 4才児の食事・きがえ・午睡と保育空間との対応における現状の問題を明らかにしながら, 同時に並行しておこなわれるそれぞれの行為に対応する保育空間のあり方を探ってきた。食事・きがえ・午睡における空間分離のしかたをパターン化すると次のようになる。パターンA [table]パターンB[table]パターンC[table]パターンAのように食事と午睡が同一時間に同一の場を用いて行なわれる場合, 次のような問題が生じる。(1)生活行為のちがいから使われる"もの"が異なりさらに場の使い方が異なるので, 食事終了のたびに机・イスを移動するという労働を, 幼児及び保育者は強いられる。(2)集団のペースから遅れた幼児は, 机・イスごと移動して午睡準備の中で食事を続けなければならない。パターンBの場合, きがえは床を使用するので, 食事のための通路で行なえる。そのため, 食事ときがえは同一時間に同一の場を使ってもパターンAのような問題は生じない。パターンCの場合, きがえと午睡をKdのように同一時間に同一の場を使用すると, きがえは布団の上で行なわなければならないという問題が生じる。しかし, きがえは広い意味では午睡準備の段階であるので, Kgのように同一の空間で行なわれることが望ましい。また, パターンCのように厨房と直結した食事室を分離させることには, 次のような利点があげられる。(1)幼児個人のペースで食事が行なえる。(2)早く食べ終えた幼児は, 長時間待たされることなく次の行為に移行できる。(3)給食の運搬がなくなり, それにより危険性が解消される。(4)保育者のもつ保育理念, 方法を基にして, 幼児ひとりひとりの健康状態・精神状態などを総合的にみた幅広い指導が行なえる。(質問調査結果より)以上のことから, 食事と午睡とは, 場を分離することでこれらが時間的に重複しても, お互いを圧迫することなしに同時点で行なえることが明らかとなり, 食事と午睡との場の分離が有効であることが示された。さらに, 食事に対しては, 厨房と直結した食事室として空間分離することが有効であることが明らかとなった。それぞれの行為に対して, それが充分に行なえる保育空間の面積を, これらの資料をもとに再検討される必要があると考える。また, 保育所における幼児の生活行為に対応した保育空間を与えることの有効性は, さらに教育的・心理的・衛生的側面からも細かい検討が必要であろう。これらのことについての詳細な分析は, 次報で検討を重ねていくことにしたい。

以上このシミュレーションによって充分とは言えないまでも, 市街地の地震時の状況像を得ることが出来た。このスタディによる地区防災計画上の総括的認識は以下のものである。地区にはそれぞれ「安全のストック」があり, この安全のストックをどう育て活かすかが計画上の要点である。安全のストックは, 物的側面だけでなく, 人的側面, 社会的側面も重視さるべき要件であり, 地区防災計画はこれらに着目してすすめれねばならない。この地区は, 他地区に較べて比較的条件に恵まれている。が, このような地区特性をより具体的に認識し, 災害像や災害対応像を明らかにした上で, この特性を活用した。より積極的, 即地的, 総合的な地区防災計画の立案が望まれる。安全のストッフや計画の方法については, 更に研究する余地があるが, これらはこのシミュレーションで発見, 検討された内容を進展させる中で, 明確化していくことが出来る。
