ジャーナル フリーIn the previous paper, the variation of temperature in concrete caused by the variation of temperature of the air was explained theoretically. In this paper, the measured temperature is compared with the theoretically culculated value and the following conclusions are obtained. (1) The variation of temperature in the concrete caused by the daily periodic variation of temperature of the air can be explained by the temperature distribution equation introduced from the conduction theory with some exceptions. (2) The variation of temperature in the concrete caused by the yearly periodic variation of temperature of the air can be explained by the temperature distribution equation above mentioned without exception. (3) The variation of temperature in the concrete caused by an attack of cold wave of atomospheric temperature when cracking of concrete was found out is able to be explained more by the sudden drop of surface temperature than by periodic variation of temperature for the application of the distribution equation above mentioned.抄録全体を表示PDF形式でダウンロード (852K) -

ジャーナル フリーThe other paper (part 1 : published in Feb. 1971) reported the plan of experiment and some of results and considerations of experiment, and this paper continued to the part 1. The subjects of this paper are shown as follows. (1) Relation between the age of strength test and the percentage of variation of weight (refer to 3.4 in the original). (2) Relation between the age of strength test and the speed of evaporation of water (refer to 3.5 in the original). (3) Relation between the percentage of variation of weight and the compressive strength (refer to 3.6 in the original). The conclusions of this paper are as follows. (1) The earlier the form is removed, the greater the evaporation of water occurs. When concrete is cured in high temperature and slow hardening cement is used, the nature as mentiond above occurs greatly. (2) The difference of quantity of water of concrete which comes on the differenct age of stripping of form remains in long term, and this difference of water affects on the strength of concrete in long age. (3) The earlier the form of concrete is removed, the greater water is evaporated. when concrete is exposed to wind or high temperature, the nature as mentioned above occurs clearly, and this difference of quantity of water-content is maintained in long term. (4) When concrete is kept under the cycle of drying and wetting condition in early age, the earlier the form of concrete is removed, the greater amplitude of variation of weight occurs. (5) When saeling compound is coated immediately after removal of form, the evaporation of water is lesser. Although this prevention of evaporation of water is not so much effective on strength. (6) In the term from seven days to six months, if water-contents of concrete is measuered, there is a little possibility to estimate the strength of concrete.抄録全体を表示PDF形式でダウンロード (1009K) -

ジャーナル フリーThis paper describes the torsion of the compressive H-section members in inelastic range theoretically and experimentally. Limit design method and elasto-plastic numerical analysis are adopted in this analysis. Especially in the latter theory, it is one of the purpose of this paper to point out the appropriateness of the judgement, whether the core of the section is elastic or not. Therefor the torsion test was carried out and compared with their theories. The section of spcimens is H-125×125×6.5×9. The both ends are restrained the warping. There are three kinds of the slenderness ratio about the strong axis, 20, 40 and 60. Also axial load ratio P/P_y has four kinds, 0, 0.2, 0.4 and 0.6. From these investigations, following conclusions are obttained. (1) Limit design method gives the good approximate estimation of the torsional yielding. (2) Elasto-plastic numerical analysis agrees with the experimental behaviour in the field of not only small deflection but also large deflection. (3) This elastic-plastic judgement, considered the torsional shair strain is effective on the analysis of the behaviour of the steel members beyoud the elastic range.抄録全体を表示PDF形式でダウンロード (1033K) -

ジャーナル フリーThis research report consists of four sections : repert (I), (II), (III) which has already presented in the preceding numbers and report (IV) which is presented here. In report (I), (II), (III) we describe about the measurement of the velocity of the wind near the building wall and the elocity in the corridor opened to the outdoor which is set on the exterior wall of the building. In this experiment, we use the single model of the apartment house and a few models arranged variously. 24 hot wire anemometers are set on the wall of the model. Report (I), (II), (III) aim at reaching some principles for setting the balanced-flue terminals and another principles for desigsing the corridor opened to the outdoor. In report (IV) we describe about the analysis of the turbulence of the air flow around the bluff body on the building wall and the analysis of the surface pressure of the wall. In this experiment, we use the two dimensional fence model and block model on the flat plate and the varions kinds of electronic instruments, for example, linealiser, correlator, A-D convetor, analogue and digital computers, etc. Report (IV) aim to clarify the diffusion of the exhaust of the gas boiler around the bluff body on the building wall and to reach some principles for deciding the position of the balanced-flue terminals which is set near the bluff body.抄録全体を表示PDF形式でダウンロード (1229K) -

ジャーナル フリーThe aim of this study is to clarify the structure of behavior and the structure of space by graspeng the relation between the man and the space as a system and by analysing the system through the behavior which is a medium between the man and the space. In this study, we made follow-up-investigation into behaviors of individual visitors to the T-amusement center and analysed them. Next we set up the simulation model, taking it into consideration that what kind of interrelations did many factors of essentials to the behavior make each other, and we tried to research in the man/space system by means of designing some operations on that model. Then we aim at the development of the man/space control system, which can estimate the human behavior in various environments by taking feedback process to the space planning.抄録全体を表示PDF形式でダウンロード (964K) -

ジャーナル フリーCost planning requires an approximation of construction costs broken down for each design stage. In dealing with building design involving basically the same type of units, such as is done for telephone offices, the work can readily be separated into functional subdivisions. This is based on the assumption that a statistical distribution phenomena pertains, even if there are some requirement differences or design individualities involued. These statistics are based upon multiples of some specific "in-place" element cost, involving the unit quantity of the "in place" element, which becomes evident as design stages develop. Based upon sufficient experience and past cost data, along with cost-increase index information, we can obtain a more accurate planning stage cost estimate than would be obtained from a one-time lump sum costruction cost estimate, by carefully and systematically taking into consideration the design of each element. When we use statistical data based on graphs, dates and costs, some cost deviation is inevitible for individually identified in-place element unit costs. However, we have devised and applied the "Theory of Deviation Distribution" to show the influence of individual inplace element costs upon the overall work picture, in order to more efficiently obtain a sufficiently occurate cost factor. We have shown the accuracy of our methode through comparison of results both theoretical and actual, based upon data made available from 25 telephone offices located all over the country. These results show an effective rationalionalization of cost estimation in the cost planning stages of telephone office construction planning.抄録全体を表示PDF形式でダウンロード (1211K) -

ジャーナル フリーOn this part of the paper, the Jurakutei-Castle has been studied from the viewpoint of the history of Japanese architecture by the use of the Folding-Screen Picture of the Jurakutei-Castle and the Rakuchu-Ezu (A.D. 1637, the oldest measured map of Kyoto) that has been discovered recently. And the contents are the following : Chap. 1 A short history of the Jurakutei-Castle from the construction to the ruin; Chap. 2 The planning on the Jurakutei-Castle; Chap. 3 The buildings in the Jurakutei-Castle; that is, Tenshu-kaku (donjon), Hiroma (main hall), Ohte-mon (main gate), and Buke-yashiki (Samurai's residence). As the result of this study, on the one hand the Shoin-style had been completed in this Jurakutei-Castle, and on the other hand the planning of this Jurakutei-Castle built on flat land seems to have been the model of another castle-town. The Jurakutei-Castle was exactly the symbol of the age.抄録全体を表示PDF形式でダウンロード (3493K)
