    This paper describes the method of determining the surface sensation of warmth and cool caused by touching the building materials. A test apparatus was developed in order to obtain the physical quantity which correspond to the psychological quantity of sensation. The rate of change in temperature (θ_V) of copper cylinder (16mm in diameter, 25mm in high) that is the physical quantity was measured by this apparatus with many kinds of material. The sensation of warmth and cool that is changed by temperature condition in the room, kinds of material, thickness of material and crvering in paint or cloth can approximately represent by θ_V as follows. The sensation is discriminated warmth and cool at θ_V=-0.025℃/s. In the sensation of warmth, it feels a little warm at θ_V=0℃/s, pretty warm at θ_V=0.075℃/s and the sensation of warmth is saturated at more than θ_V=0.1℃/s. In the sensation of cool, it feels a little cool at θ_V=-0.054℃/s, pretty cool at θ_V=-0.135℃/s and the sensation of cool is saturated at more less θ_V=-0.2℃/s.

    防水用高分子材料の耐候性評価研究の一環として, 屋外暴露試験を実施し, 紫外線量・試料温度に注目して検討し, 以下の結論を得た。(1)ここで測定した紫外線量・試料温度のデータを, すでに前報で得ている光と熱による変質劣化を表す式に代入して求めた計算値は, 屋外暴露試験結果とほぼ近く, 紫外線量と試料温度を用いて屋外環境下での材料の変質劣化をほぼ定量的に取扱うことが可能である。(2)暴露状態の差異が明瞭であり, 断熱材上の試料の場合, 試料温度が高い状態下で紫外線を受けるため変質劣化が最も著しい。金網上の場合は, 同量の紫外線を受けているが試料温度がそれ程上昇せず, またアンダーグラスではガラスによる紫外線強度低下のため変質劣化は緩慢となる。また日陰の場合は直接的な太陽光線からは保護されているため変質劣化が非常に小さい。(3)材料の変質劣化に及ぼす季節の差も大きく, 夏季間は試料が比較的高温状態で紫外線を受けるため, 計算上最も変質劣化が進行する。逆に冬季間は紫外線量も少なく, また試料温度も低いため変質劣化は小さい。春秋季間は前二者の中間程度である。(4)屋外暴露試験と光熱劣化試験との関係は, 太陽光線と本実験で使用した光源とが分光分布, 強度等の点で同一でないため厳密な議論はできないが, おおまかには, 例えば断熱材上の透明材料, 屋外暴露1年間に相当する光熱劣化試験条件は試料温度40℃前後で, JIS A 1415の条件に最も近い光源からの距離50cmの場合約870時間, 2年間に相当するのは約1730時間程度であるという結果が得られる。また金網上の場合に相当させるためにはもっと試料温度を低下させる必要があり, アンダーグラスの場合に相当させるためには, 試験時間を少なくする必要がある。これらの事は屋外暴露試験と光熱劣化試験との相関性を論ずる場合, 紫外線量とその時の材料の温度を知る必要があること, すなわち材料が使用される部位, 条件等が明らかでなければ適正な相関性を論ずることができないことを示している.なおここでは水分の影響については全く考慮されていないが, 一部, 例えば断熱材上の試料では計算値と屋外暴露試験結果に若干の差があるものもあり, この原因の一つに水分の影響も考えられ, 水分の効果も含めた定量的な取扱い, 評価については今後の課題である。

    An analytical method for accumulative plastic deformation under random loadings is described. The analysis is based on a hypothesis of accumulation law and stochastic equations for randomly accumulated plastic deformations. As analytical models, cumulative behaviors of plastic strains for Steel and Steel Reinforced Concrete members under random curvature amplitudes with constant axial force are treated. Analytical expressions and some numerical results are presented with Monte-Carlo simulations. Detailed behaviors on the analytical results are discussed in the following paper [II].

    This paper deal with the experimental and theoretical study of the rigid frames with triangular stiffeners located in the plane of the beam franges. The purposes of the paper are to certify the applicability of the author's formulas (see ref. 18), 19), 20)) to the connections under lateral force and to survey the effects that the deformation of the beam flange connections and panel zone have on the elasto-plastic behavior of the structures. Theoretical analysis of the structures took into consideration the deformation of the beam, column, beam flange connection and panel zone as well as the P-Δ effect of the column. The conclusions from the study are as follows; I) the analytical results simulated very well the elasto-plastic behavior of specimens. II) the author's formulas to determine the strength and the deformation of the beam flange connection in the elasto-plastic range are applicable for structures under lateral force. III) the rigidity of the panel zone in the plastic range is about 4% of the one in the elastic range. IV) the deflection of the actual structure is considerably greater than the structure with ideally rigid connections. V) the deflection caused by the deformation of the beam flange connection is nearly equal to the deflection caused by the panel zone in practice. VI) P-Δ effect affects the deflection after yielding of the structure and also the ultimate strength.

    The maximum strength and deformation capacity of cold-formed rectangular hollow section members subject to local buckling under axial compression were investigated experimentally. The influence of residual stresses due to cold-working on the strength and deformability was made clear through the comparison of these characteristic values of cold-formed tubes and those of the corresponding stress-relieved tubes. Finally, the empirical formulas which predict the local buckling strength and the deformation capacity of cold-formed rectangular hollow section members under axial compression were derived through the statistical approach.

    The purpose of this paper is to consider about cyclic hysteretic behaviors of structural steel in unstationary and stationary state subjected to cyclic tension-compression test under a constant strain amplitude after plastic pre-strain and to make a proposition for hysteretic stress-strain relations under random strain amplitudes using the relationship between secant moduli and strain ranges of the stationary hysteretic loops. The test specimens are manifactured by machineworks from reinforcing bars (SR 24, 16mm diameter) and steel plates (SS 41, SM 50, 16mm thickness), Load is applied by a universal testing machine through the gripping devices for tension and compression tests. In regard to the cyclic tests under constant strain amplitudes and the proposed method for prediction of behaviors of steel under random strain amplitudes, the results are summarized as follows; (1) Hysteretic loops under a constant strain amplitude become stationary after several cyclic numbers, In the case of large amplitude, the stationary loops can be moved in parallel along the strain axis according to the pre-strain and in the case of small amplitude (R<4ε_Y), they cannot be moved by the above-mentioned method, but when the upper revarsal point is in the strain-hardening range, they can be moved by the same method. (2) The experimental curves of cyclic stress-strain relations under random strain amplitudes can be followed by the proposed method with good accuracy.

    Elasto-Plastic analysis of plates has been underlain by those theries mostly for the bending, with membrane effects considered, or the large diflection which are hardly accountable for other prime considerations of the shear effects. This report presents a method to take account of them by extending Reissner's approach, which can reasonably include the effects notably of transverse shears in terms of force and deformation, so that the inelastic range can be covered also in that direction owing to laminated types of finite elements. The subject matter is quantitatively discussed in a series of examples of plates differing in their relative thickness.

    In order to increase the safety of structures under earthquakes, it is indispensable to add the reliability of estimate of the strong ground motion. Under the assumptions of the Poisson distribution of earthquake occurrence, the Gutenberg-Richter's magnitude law and the attenuation relation, a large number of extreme values of yearly maximum earthquake ground motion are simulated by the Monte Carlo Method. The findings indicate that (1) the plotting position for the extreme values of earthquake ground motions agrees well with that of exponential distributions and (2) the distribution of the largest values is approximated as logarithmic normal distribution. Assuming that the distribution of the largest values is the logarithmic normal distribution, the control curves related to the mean and variance of the largest values can be established by an analytical procedure. As the analytical control curves of ground motions at Fukuoka and Tokyo agree well with the observed distributions for the period of 90 years, it is concluded that the combination of analytical control curves and observed extreme value distributions are convenient for an estimator of the probabilistic design load for the earthquake resisting design.

    We deduced regression equation, which can approximatey estimate a damage ratio of the houses hit by the Okinoerabu Typhoon, by means of quantification analysis with combination of some topographical factors. Then we made clear the effects of every factor. From the results, we made some following conclusions. (1) The kind and size of topographical factors, which have effects upon damage of houses hit by a storm, vary according to the undulation of the island. In an island, which undulates considerably, slope state has close connection with a damage ratio. But in the island, which does not undulate a great deal, effects of the sea have a close connection with a damage ratio. (2) We presented a new method which defines the scale of a topographical factor. The method analyzes the topographical wave length by cluster analysis. The scale is the range in which topographical wave changes occor. (3) Analysis of the topography is to analyze topographical wave length. (4) The results of interpreting aerial photographs of houses hit by a storm were accurate in showing complete destruction or half destruction of house.

    1-1 To make the controller of skace clear There are four standpoints of the controllir of skace; an arderes, an owner, a manager and a user. And they have complicated relations actually. It seems right that the controller of space should be a user, but various problems have occurred, as the orderes is misunderstuood to be the controller of skace. 1-2 To isolate the territory The physical isolation of space has been needed in order to secure functons, but the isolation of space by means of a promise is sometimes needed. And the spaces that are articulated by means of physical isolation are connected by the spaces that ore not articulated. These spaces that are not articulated are characterizcd by promises. If they are compressed, the multiformity of human behavions will be damaged. 1-3 To make a space composition fit for the function To satisfy the function, a planmer compores spaces logically considering the objective data and concept that is given previonly. At that time he excludes the factors that cannot be grasped objectivity. 1-4 The isolatin of life space Life space is isolated by hard promise, aoft promise and physical setting. Physical setting has threc types; the spacial isolation, the isolation by distance (proxemics) and the symbolic isolation. The isolation by distance and the symbolic isolation is supported by soft promise. Unit-space that is ayticulated by only the spacial isolation is apt to eliminate most of free human behaviors.
