JOURNAL FREE ACCESSIn this paper response characteristics of root incomplete penetration, which appears on surface, in ultrasonic angle beam testing is described on the basis of results of tests on natural defects. The echo height of root incomplete penetration is lager than the echo height of 4φ×4 drill hole of NDI-STB-A 2. Therefore root incomplete penetration can be detected without miss by the general specified sensitivity in Japan. Response characteristics in methods for estimating the sizes of defects is resemble to inner incomplete penetration, but in DISTANCE AMPLITUDE CORRECTION D_s METHOD with 4φ×4 drill hole of NDI-STB-A 2, D_s value must be minus 2 decibels, which is larger than D_s value of porosity and inner incomlete penetration. Distance amplitude characteristics of root incomplete penetration is closely akin to 4φ×4 drill hole of NDI-STB-A 2.View full abstractDownload PDF (885K) -

JOURNAL FREE ACCESSIn this paper the aseismic safety of medium or low rise reinforced concrete rigid frames without shear walls is investigated on the basis that the steady-state resonance of such a frame as subjected to the sinusoidal forces at the foundation is able to be considered as the critical state. The criteria of the aseismic safety are given by applying the elasto-plastic hysteresis loops and fatigue characteristics of reinforced concrete members to such a critical state. Consequently the allowable maximum acceleration amplitude of the forced ground vibration is expressed as the function of the ductility factor (μ) and the factor F(s) which is related to the shape of the hysteresis loops (cf. Eqs. 17, 17', 17"). Numerical examples on the aseismic safety of one-story and four-story real reinforced concrete structures are presented. From these examples it is able to be concluded that the necessary minimum base shear force coefficient of the ordinary types of medium or low rise reinforced concrete rigid frames is about 0.6.View full abstractDownload PDF (1065K) -

JOURNAL FREE ACCESSFollowing Part 1, in this paper various factors which have influences on the restoring force characteristics of reinforced concrete aseismatic elements are examined through the tests. The factors which are discussed in this paper consist of the dimensions of members and cross sections, the quantities of reinforcements, the vertical load on the top of the column and loading types such as lateral loading, diagonal loading, static loading and dynamic loading. In the skeleton curves the influences on strength and stiffness and in "Normalized Characteristic Loop" those on loop shape and hysteresis damping are mainly discussed.View full abstractDownload PDF (1155K) -

JOURNAL FREE ACCESSParticularly in high storied buildings, since they are subjected to large repeated horizontal forces due to the earthquake and wind, there are several occasions that braces are set into frames as the structural elements against the external forces. Since, however, the brace bears a large axial force, it is needed to secure the rigidity and ultimate strength, so that a large cross-sectional members must be used. As a result the slenderness ratio (L/r) becomes comparatively small in the order of 30〜70, and consequently a brace on the compression side is apt to break down by plastic buckling. In order to clarify the mechanical behaviour of a structure having such characteristics analytically, this paper deels with nonlinear analysis taking consideration of the nonlinearity due to the yield of materials and the nonlinearity baced on the finite deformation theory unable to be neglected in the behaviour of instability problems. For the purpose, the behaviour of compressive members with different slenderness ratio was first analyzed for repeated loadings, and after making various checkings of the results, the analysis of the behaviour of 1 story 1 span frame provided with K-type braced is made for the case in which a repeated horizontal force is applied.View full abstractDownload PDF (1194K) -

JOURNAL FREE ACCESSThe Room Space comes under the psychological influence variously. Especially, when their characters are built up, Infants are affected greatly by the Room Space in which they have been grown up. But, It is very difficult to seek an early solution by one effort, because it contains very much complicated matter. Therefore, we want to get fundamental reactions by Infants for the Form of the Room Space and the Texture inside of it in many complex elements organizing the Room Space. And we find it in my heart to get a clue to solve a probrem by them. The first step, it is to investigate when Infants discriminate the elements in the Room Space. The second step, it is to seek after contents interested in them. And we made five experiments as follows. 1. Form discrimination of two Room Spaces. 2. Texture discrimination of two Room Spaces. 3. Examination of discriminating experiments. 4. Form choice of the Room Space. 5. Texture choice of the Room Space inside. For the result of the experiments, the age that is able to discriminate the Texture of two Room Spaces is earlier than the age that is able to discriminate the Form of two Room Spaces. The former is 1 year 6 months old around, and the latter is around 2 years old. But the age having an interest in the Form of the Room Space is earlier than the age having an interest in the Texture. Before 2 years 6 months old, Infants are interested in the complex, labyrinthian Form of the Room Space, but uncertainty. After the age, they begin start doing to seek after the width of the Room Space. Though Infants discrimate the Texture of the Room Space early in life, it is so late, around 5 years old to take an interest obviously in the Texture of the Room Space.View full abstractDownload PDF (1037K) -

JOURNAL FREE ACCESSThis paper has two main purposes : one is to make clear the size and form of the great south gate, the inner gate and the cloister corridors of Yakushiji in the Heijo capital and the Fujiwara capital and the other is to consider the manner of construction of these at Yakushiji in the Heijo capital, on the basis of the data gathered by excavation and from the Yakushiji-Engi (The History of The Yakushiji Temple). Some principal conclusions from the result of this study are as follows : 1. At the original Yakushiji in the Fujiwara capital the great south gate and the inner gate were of the three-bay type, and the cloister was of the single corridor type (one bay wide). 2. At first when the Yakushiji was founded in the new Heijo capital, it was planned to be built in an imitation of the original Yakushiji in Fujiwara. The inner gate was moved from the older Yakushiji, and some parts of the podia of the corridors were modeled after those of the older temple. Before this could be completed, the work was interrupted. 3. In resuming construction the oiginal plan was modified so that the buildings could be made more elaborate. After 747 the cloister of the double corridor type (two bays wide) and the great south gate of the five-bay one. 4. When Yakushiji in the Heijo capital caught fire in 973, the great south gate, the inner gate and the cloister were burned down. These were then reconstructed on the same scale as before. However of the east and west side gates of the cloister, which existed before the fire, only the east gate was rebuilt.View full abstractDownload PDF (1739K) -

JOURNAL FREE ACCESSThe main temple of Hachiman-Usa Jinguji temple was built in 738 by the force of the private wealth. The first Buddhist Monastry of the temple was completed in Nara Period. The main temples of the second Jinguji temple were called Zanmaido and Tahoto etc. These architectures were built in Heian Period. The second Buddhist Monastry was completed near to the first Buddhist Monastry. The lectures were put in Mirokuji temple (Jinguji temple) in 829 for the first time. It means that this temple was under the control by the force of the state. The Mirokuji temple developed greatly in Heian Period. It is important that Buddhist architecture had an effect on the shrine architecture in Heian Period. My paper on the architecture aspects of this temple consists of these five parts. 1 Introduction 2 The first construction of Jinguji temple 3 Jinguji temple in the first period 4 Jinguji temple in the second period 5 ConclusionView full abstractDownload PDF (1528K)
