ジャーナル フリーAlthough aggregates have been generally classified lithologically, minerallogically, chemically, physically and geometrically, they would be subjected also to a classitication from the viewpoint of physical chemistry. On trying to classify them by the streaming potential, it is found that each kind of aggregates has an individual potential value. Sedimintary rock gives streaming potential of 5 to 100mV, while Igheous rock more than 100mV. Metamorphic rocks are between 37 to 49mV. Minerallogically, quartz, feldspar and limestone give 138mV, 114mV and 24mV, respectively. Chemically, the higher content of solble SiO_2 shows the higher potential and the relation between them is expressed by ST=890SS+401.3 where ST means the streaming potential and solble SiO_2 Content. It is considered that SiO_2 affects the potential to the negative side and CaO+MgO having +2 ion affects it to the positive side, but Fe_2O_3 or Al_2O_3 having +3 ion gives no effect on the potential because of its insolbility to water. In general, the aggregates generate ions on their surface by contacting with water and, at the same time, am irregular ionic distribution occurs in the water, then the streaming potential is to be measured when water is trans-ferred by pressure, so that it is possible to distinguish whether the aggregates react easily with an aqueous solution or not. As an example of an aggregate extremely reactive with aqueous solution can be mentioned alkaline reactive aggregates. The alkaline reactive aggregate is charecterized by the high content of soluble SiO_2, K_2O+Na_2O. Byrex glass consistes many of them and its spotential is very great value.抄録全体を表示PDF形式でダウンロード (602K) -

ジャーナル フリーIn the previous report, a new method of composing Sandwich Curtain Wall was proposed. The Curtain Wall is made in the following way. 1. Steel-bar-grid is attached to the structural frame. 2. This grid is sandwiched between two special concrete plates. 3. These two are combined by concrete set between them. 4. By the previous experimental study in which 1.8m steel bars were employed, this method of composing Sandwich Curtain Wall is shown to be eassy, exact and rapid. The present paper deals with the experimental study on composing the Sandwich Curtain Wall inside of the wood frame (3.04m×6.04m). The results obtained are as follows : 1. It is not necessary to set stud in the fram. 2. Only vertical steel bars need to have hardness and horizontal bars only have to be united with that. 3. This method of composing Sandwich Curtain Wall is easy, exact and rapid. 4. Concrete placed between the panels can hold these panels tight around the frame. 5. Transportation by truck causes very little damage to the panels.抄録全体を表示PDF形式でダウンロード (1317K) -

ジャーナル フリー地震時に於ける骨組の挙動を知る上で, 繰り返し荷重下の骨組の荷重変形曲線を求めることは重要である。本論文では既に前報告で骨組の一方向荷重下に於ける荷重変形曲線を求める方法について述べたので一方向荷重下の荷重変形曲線との関連に於て, 繰り返し荷重下の荷重変形曲線について論ずる。解析方法の妥当性は一定軸力下で繰り返し曲げを受ける柱材の実験により検討される。抄録全体を表示PDF形式でダウンロード (825K) -

ジャーナル フリーIn culculating the inelastic earthquake response of a multistory building, we usually substitute a shear vibration system for that multistory building to make it more simple. In this paper, however, a bi-linear force-elongation property is prescribed for member of the truss structure, and the inelastic earthquake response analysis is carried out. First, we led the dynamic equilibrium equation, and the assumption on which numerical analysis was made by using a digital computer was discussed. Then, the resultes of the response of this truss system were compared with those of the replaced shear vibration system in which spring constantes were decided by forces corresponding with the first mode shape of the truss system.抄録全体を表示PDF形式でダウンロード (1034K) -

ジャーナル フリー本論文は先に発表した単純な高力ボルト引張接合部の基本的性状に関する実験の結果を基礎として, Split Tee形式の高力ボルト引張接合による柱はり接合部の性状を検討したものである。このような柱はり接合部ではボルト接合部分, 接合部パネル部分それぞれの変形および耐力の相互関係, 正負交番荷重をうける場合の挙動, 接合部の靱性等が問題となる。これらの諸点を調べるために一連のボルト接合試験体を製作し, 更に比較のため同一寸法の溶接による接合部を持つ試験体も用意した。我国では水平荷重をうける柱はり接合部の設計が構造計画上主要な点の一つであり, その意味から接合部パネルの挙動と高力ボルト引張接合部分の挙動との関係を追求する必要があると考え, 接合部パネルの強度とボルト接合部分の強度との比を変えた試験体を主系列とした。抄録全体を表示PDF形式でダウンロード (1223K) -

ジャーナル フリーThis paper treats the wear by aging of steel sash in order to contribute fundamental data for building maintenance. Twenty two telephone and telegraph office buildings aged from two to fifty years in Kinki district were selected and their sashes were observed and measused when the buildings were extended or repaired and sashes were removed. As result, the bollowing conclusions were obtained : 1. The relation between wear of sash frames and ages for older ones (20〜40 years) nearly agrees to Kobayashi's formula, y=0.5t^<1.3>. 2. But for newer ones (less than ten years), because of improvement of painting and adoption of caulking, etc, . wear is somewhat small and relation with ages is y=0.24t^<1.29>. 3. According to the measurement of corrosion about removed sashes, their corners are most greatly worn. Adoption of stainless steel for the sill and the lower part of the vertical (10cm high) is very evective. 4. Concerning painting of sash, erosion of oil paints appear from 200 hours in the weathering test. Synthetic resin paints are hardly changed in the weathering test of 1, 500 hours, but changed a little in the salt spray test of 1, 700 hours. So it is recognized that synthetic resin paints are rather durable than oil paints.抄録全体を表示PDF形式でダウンロード (1244K) -

ジャーナル フリーThis report deals with the analysis of the correlation matrix by the method of factor analysis. The matrix consists of 15 variates that are related to building planning of rural public elementary schools in Hokkaido. The size of each variate is 130 and the picked out variates are as follows : (1) Households; (2) Population; (3) Average distance from the school to a grocery shop, a clinic, a hospital, a public hall, a cinema, a police box, a bus stop and a railway station(km); (4) Enrolment; (5) Classes; (6) Teachers; (7) Outdoor playing space (in Tsubo); (8) Number of years since building; (9) Attendance area (km^2); (10) Outdoor playing facilities; (11) Classroom; (12) Main teaching facilities; (13) Social club activities; (14) Use of broadcast and television instruction; (15) Use of the classroom by the inhabitants, in each school and its district. A four factor pattern is derived from this matrix, and the first factor is found to contribute about 40.2% of the variance and the second about 9.5%, the third about 8.7%, the fourth about 8.5%, making about 66.9% for the four, and the final factor solution is obtained by the varimax rotation. The first of these factors is named "fundamental factor". the second is "the regional difference factor", the third "the facilities factor", and the fourth "environmental factor", respectively. Finally, the factor scores for individual schools are calculated.抄録全体を表示PDF形式でダウンロード (790K) -
