The object of this paper is to clarify the relation of the tactile roughness of building materials to the physical one. The tactile roughness of twelve samples were determined by the paired comparison method. The coefficients of friction were adopted as the physical roughness. To satisfy the purpose, A ROUGHNESS TESTER has been developed. A good correlations between them can be obtained by the equation below : Z_j=2.70logμ+1.08 where Z_j : Tactile roughness value μ : Physical roughness value

It has been reported that the properties of Normal Portland Cement and Gypsun are improved by the particle or fiber reinforcements, but there are few researches concerning with the relations between the improved properties of particle or fiber reinforced matrices and the structural performances of members. Then we carried out some investigations on this ploblem. In this paper the method of the analysis and the results of the theoretical study are explained and in next paper (part 9) the experimental study will be reported. The properties of inorganic matrices like Normal Poltland Cement and Gypsum are improved by the particle or fiber reinforcement on the tensile strength, bond strength and toughness. A beam bearing four point simple bending is chosen as a model in the analysis so that the improved properties of matrices are to be distinctly indicated on structural performances. In the analysis load-deflection curves of the beams are estimated by the elastic-plastic theory on the suppositions that the cross section of the beam keeps plane and after the initiation of cracks the tensile zone of the matrix is ignored. The results of the analysis as follows are obtained. The particle or fiber reinforcement of matrices improves the structural performances of the beam that are the crack initiation load, bond strength, shearing strength and absorbing energy until ultimate fracture.

The settlement behavior of both single piles and pile groups in clayey soil due to vertical loadings and ground settlements are studied theoretically. And the applicability of the theory to site phenomena and model experiments is discussed in thisreport and will be discussed in latter serial reports. The analytical method in this paper is one of the stress methods basically shown by D'apporonia and Romualdi (March 1963 A.S.C.E.) and authors generarized this method to more realized theory. Considering the "supernonlinerity" of stress-strain characteristics of soils, equations are developed using incremental quantities of pile forces and other variables. Assumptions used in introducing the fundamental equations are as follows. 1) Piles are usually considered elastically compressible but inelastic compressibility can be considered when it is necessary. 2) The constitutive relations of soils are based on the rheorogical model (Fig.3) proposed by authors. 3) Mindlin's 1st solutions are used as influence factors for true elastic behavior of the ground. But authors considered the existence of pile shaft and corrected the influence factors by solving the problem of half infinite elastic body having a bored hole the same as pile shaft by Finite Element Method. 4) Fundamental equations are not positive functions of time as the stationaly conditions are treated. The theoretical calculation results are in good agreement with observed data including small and large settlements by short or long term loading and their repetition, negative skin friction phenomena and so on.

In the previous paper, Part 2, an analytical model has been developed to simulate the bond-slip behavior between the deformed bars and concrete. In this model the theory of orthotropic materials is applied to the internal crack zone of concrete around the deformed bar and the model gives a good match with experimental results for the previous pull out specimens. In this paper, finite element calculations are compared with experimental results for the previous tensile specimens (4, 5, 6, 7). The results are as follows. 1) The analytical results of the load-slip and the load-steel strain distribution relations obtain a good agreement with experimental results. 2) When the angle of the internal crack is 90°, the concrete strain at D distance from the bar gives a good match with experimental results, but there is a difference at the surface of the loaded end. (D : Diameter of a bar) 3) When the specimen is divided into two angle zones, 60° and 90°, of the internal crack which are similar to the actual condition, the concrete strain distribution of the loaded end gives good results. And the deformation perpendicular to the bar axis has appeared near the loaded end. This deformation was also observed in the real specimen. 4) It is necessary to be divided into finite elements more roughly in order to apply this model to the member and so on. Giving consideration to this point, an analytical model is developed using the linear strain triangular elements. The analytical concrete strain at D distance from the bar is about twice as large as the experimental one on accout of linearly varying strain in the element, but the analytical concrete strains at more than 2D distance from the bar obtain a good agreement with experimental results.

In this paper (II), the mathematical models of "Resonance Fatigue Characteristics" of structural materials, which were introduced in the previous paper (I), are verified qualitatively as well as quantitatively by experimental data on the typical building materials, concrete and steel, which are considered to correspond to "Slip Type" and "Loop Type", respectively. The investigations on structural materials in the previous (I) and this (II) papers give the basis on which the "Rsonance Fatigue Characteristics" of structural elements and structures are able to be discussed on.

This paper is concerned with the solution of Boussinesq's problem for a transversely-isotropy. This problem can be solved by superposition of foundamental solution and two solutions obtained by synthesis of nuclei of strain, which are symmetrical about rolling axis. And the authors show some numerical results of this solution.

In the present paper, a new method for the dynamic buckling analysis of rotational shells with initial imperfections is formulated based on the finite element method and mode superposition method. This method avoids the direct finite element method of nonlinear effects and also takes advantage of the important feature that structural response is fundamentally due to several basic vibration modes. The two in-plane displacements u and v are explicitly obtained compatible with the assumed lateral displacement w and initial imperfection w^I, both of which are expanded by free vibration modes. The governing equation is composed of a set of algebraic cubic polynominal equations in terms of the generalized modal displacements. The coefficients in the equations for a shell with an initial imperfection are obtained through a simple matrix manipulation of those for the perfect shell and the coefficients in Fourier expansion of the imperfection. This formulation can treat with a nonlinear dynamic stability problem subjected to time dependent axial and lateral loads also a problem with nonlinear inertial forces. The pressent method is applied to solve the axisymmetric dynamic buckling of clamped spherical caps under a uniform step load, whose shell parameter λ ranges from 5 to 10. Imperfection sensitivity of the dynamic buckling load is investigated as well as both of the static and astatic buckling loads. The dynamic buckling load, determined in numerical responses, is found to lie between the static and astatic buckling load. This tendency is valid in case of shells with initial imperfections. Then, the astatic buckling load can be considered as a lower limit for the axisymmetric dynamic buckling.

In this paper the rigorous formulation of the motion of elastic rods which take an arbitrary shape in space has been obtained from the three-dimensional theory of elasticity. All the expressions are referred to a certain natural state. The derived general theory can deal with the large displacements and large rotaions and further the deformation of the cross section of rods, and it is applicable to the rod for the geometrical nonlinear and physical linear. The general theory is the approximation of a rigorous derivation of the curved and twisted elastic rods in reference (25). From this point of view considering the main displacement, it is assumed that the displacement consists of the mean displacement of section and the warping. The warping is expressed by the power expansion. A fully consistent set of foundamental rod equations has been derived systematically through the modified Hellinger-Reissner's variational principle. Using the assumptions of thinness, the simplified equation is considered for practical uses. Also, the linear theory of rod is represented the two kinds of expression corresponding to the nonlinear theories and is discussed the correspondence of classical theories. As the resultants, the assumption of the rigid displacement of the cross section in classical theories can be introduced independent of the thinness of rod and of the curvature and torsion of axial curve. Also it is obtained that the classical theory of rod rest on the basis of the Bernoulli-Euler hypothesis can be not obtained the exact expression unless the assumption of thinness is used in addition to the Bernoulli-Euler hypothesis. In this paper, the straight line and plane curve of axial curves are contained.

This is an experimental study on a measurement of the sense of oppression caused by a building, and has two principal purposes. One is to make the visual sense of oppression, caused by a exterior wall of a building, correspond to physical values, that is to propose the equation for estimating the sense of oppression caused by a building. The other is to estimate the permissible values of the sense of oppression. As the preparatory stage to accomplish the two main purposes of the study mentioned above, this paper attempts to describe about Experiment I and Experiment II. In Experiment I, we tried to find the psychological meaning of the sense of oppression as the subject of this study. As a result, the sense of oppression is a kind of unpleasant one caused by volumes of a exterior wall of a building, through vision in an exterior space. And it is also consciousness of being sufferer, namely being "pushed on", "compelled", "overhanged". In Experiment II, we mentioned the availability of the device for the experiment-wide view projection system composed of three screens. The contents of this paper are indicated below : 1. Introduction 2. Experiment I : Psychological analysis of the sense of oppression caused by a building a) Subject of this experiment b) Method of this experiment c) Result and discussion 3. Examination of this experimental method a) Psychological scales b) Improvement of evaluation method c) Adopting the wide view projection system 4.

The aim of this paper is to grasp the housing demands of public housing households, by analyzing both their assessment to their own houses and their latent demands. The conclusions are as follows; 1. The public housing households are classified into following six groups according to their housing demands. I. those who are impossible to buy their own homes inspite of their desires. II. those who are content with public housing and wish to live in their homes for ever. III. those who can't move into the alternatives to public housing and, therefore, have to live on. IV. those who are discontent with their homes and wish to move into better rented housing. V. those who wish to become owner-occupier and have a plan of movement. VI. those who temporally live in public housing and intend to move into their parent's homes 2. One half of the public housing households belong to group I. The ratio of the household that belongs to group II and III is 10〜20% respectivelly, though the former is remarkable in the rural town and the latter in the industrial city. Group IV and V occupies 10% in the big city and the local city respectivelly. Finally group VI occupies less than 10% in all area. 3. Group II is at the bottom of the income distribution. More over considering that the ratio of matured household is higher in the big city, it would not be true to say that residential condition is good in this group. 4. Group V is at the high level of the income distribution and many of them belongs to the third income quintile group. 5. Group VI is younger than any other groups and their residential condition is good. 6. The extent of latent housing demand constitute the one of factors which create housing dissatisfaction. 7. The ratio of the public housing households who need any assistance to achieve their housing demands is more than two thirds of all dwellers.

It is said that Inuyama castle-tower was founded in about 1537, in Muromachi-era. At present, this is an established theory and there seems to be no room for doubt in it. However, the examination of basis of this theory brought about some new views. The new views are roughly as follows. 1. The first and second floor of the castle-tower are hitherto said that they were constructed in about 1537 by Nobuyasu Oda, but it is proved that they were built in 1601 by Yoshitsugu Ogasawara. 2. The third and fourth floor are hitherto said that they were built in about 1600 by Yoshitsugu Ogasawara, but it is also proved that they were built in about 1620 by Masanari Naruse. 3. Therefore, Inuyama castle-tower was, founded not in Muromachi-era but in early Edo-era (or Momoyamaera).

One of the most famous architectural treatises in the Renaissance Age, "La Regola delli Cinque Ordini d'Architettura" by Vignola was first published in Roma, 1562. It has the following characters and forms. 1) It was published under the patronage of the family Farnese. 2) It was given the important privilage from the Papa Pius IV and other most strong powers. 3) Vignola's intetion of this publicastion was to show the system of proportions of Orders, in according to research the antic Roman Architecture. 4) His audience was not much cultivated men, but anyone who had an ordinary taste to art. 5) He use beantiful minimum number of plates by engraving. 6) This book has the orderly composition. 7) He use the unit "Modulo", from the total part to the details. 8) The short captions and glosserly was added to the plates. 9) His system of proportion was gaimed by symplifying the precedent systems and the examples of Roman Architecture. 10) Above all, the height of orders was symplifyed.
