The purpose of this paper is to investigate the thermal expansion and contraction caused by the ambient temperature changes of an existing reinforced concrete building. According to the past literature, thermal expansion and contraction of a building corresponds to the joint width changes at the expansion joint. Thus, thermal expansion and contraction were measured with a slide caliper at the expansion joint twice a day over a period from April 9, 1984 to January 24, 1986. The conclusions are as follows : 1) Thermal expansion and contraction at. the top story was shown to be correlated with the atomosoheric temperature, while other stories showed a correlation with the room temperature. 2) Room heating prevents thermal contraction and decreases thermal stresses in the case where the building is warmed uniformly such as in this building. 3) The relation between temperature and thermal expansion and contraction describes a definite loop in a one year cycle. This was verified. 4) The maximum value of thermal expansion and contraction of the building is measured at the top story. Thermal expansion and contraction for one day is occasionally equal to 1/3 of the value of an year.

Thin walled structure, pneumatic structure and suspensional membrane structure are the one of light weight structures. These structual materials which retains load-carrying capability with only tensile stress components. has a lot of potential application in space. For the stress field that characterizes mechanical behavior of these structures, there is the tension field. The tension field is uni-axial stress one. We already proposed of the numerical procedure on tension field analysis. The procedure follows formulation of the finite element techniques with variable stiffness. We made sure of availability and efficiency for our procedure through mathematical consideration and numerical results for the plane tension field. In this paper, we discuss about the method of curved tension field analysis based on the proposed procedure. At first, we examine geomentrical relations on the carved surface. We evalut on the stiffness through this relations. This procedure used to a stiffness method and a stress transfer method. As sample problems, we select a cylindrical sheet model. The method is applied to this model with several load conditions. Tension rays on the curved surface are shown definitely as our numerical results. Finally, the systematization for the procedure of the tension field analysis is shown using a diagram.

Expressins, which can evaluate the ultimate bending strength about principal and diagonal axes continuously all range of axial load, were already proposed (see reference 2). One of the problems of these expressions, that was the method to express the effect of reinforcing bars arrangement, is cleared using equivalent distance between centers of reinforcement gravity, tention and compression group each other (Eq.(1)〜Eq.(3)). About ductility of flexure members, location of neutral axis and strain of extreme compression fiber are generally considered, and this paper propose expressions for calculating the former, formed by the ratio of compression area (Eq.(18)〜Eq.(20b)) and expression for calculating the latter (Eq.(24a)〜Eq.(25b), see Fig.7(a), 7(b)), using the relation of blanced axial load (Eq.(21)〜Eq.(23b)), see Fig.6), about principal and diagonal axes respectively.

This paper discussed the mechanism of stress transfer and the strength of beam-to-column connections with/without stiffening plates. The conclusions attained are as followings. (a) From the results of the model tensile tests of the connections without stiffening plates, i) The strength of the connections depends on the width and thickness of column flange, the thickness of column web and beam flange, and the steel grade of the materials used. ii) The yield and maximum strength of the connections can be evaluated by Eq.(4), which was proposed by Zoetemeiier P., and Eq.(6) respectively. (b) From the results of the model tensile tests of the connections with stiffening plates, i) Four fracture modes are observed, i. e., Mode W, WS, S and E (see, Fig. 9). ii) The maximum strength of the connections of Mode W or WS can be evaluated by Eq.(10) or Eq.(12) according to the ultimate strength of the welding seam between stiffening plates and column flange. iii) Eq.(14) is obtained experimentally for the maximum strength of the connections of Mode E. (c) From the results of the sub'assemblage tests, the evaluating equations of the maximum strength of the connections obtained by the model tensile tests are applicable to the connections of the sub-assemblage conservatively.

In this paper, deformations in a ground are discussed through the experiments. Very small deformations are measured in the following method. The strains in a ground caused by loading are measured by the strain gauges, and then the deformations were derived through the measured data. Distributions of vertical strains under the center of the base have the following characteristics. The depth where the maximum vertical strains are caused by foundation continuous footing (the depth is dimensionless) becomes less deep as the width of the foundation increases. Moreover, the depth where the strain can be regarded as almost zero becomes less deep as the width of the foundation increases. In case of circular foundation the vertical strains under the center of the base show almost the same distributio!is. These facts have the totally same characteristics as was shown by the previous paper in A. I. J. No. 365. Moreover, the predicted settlements of foundation in the previous paper are almost the same with the results of the experiments. In case of foundation continuous footings, 80 % of the settlement of foundation is caused by deformation of sand bases less deep than the double value of the width of the foundation. As for circular footings, about 70 % of the settlement of foundation is caused by the deformation of sand bases less deep than the diameter of the footing.

This study is concerned with relationship between pressure and settlement observed from long-term elate loading tests on Kanto Loam. Conclusions are as follows ; (1) Settlement of Kanto Loam consists mainly of an initial, transient and Creep settlement. (2) Both of transient and creep settlement, after initial settlement, can be put on linear line when these settlements plotted on semi-logarithmic graph by taking time factor logarithm. (3) Rate of settlement in condition of transition and creep depend on unit weight, elastic modulus of Kanto Loam, plate width and depth of plate. (4) Predicting rate of creep settlement after 10 years is nearly equal to 10〜80 per cent of the initial settlement in long-term plate loading tests.

This paper is the second report in a series of studies on the settlement process of frame structures on poor grounds. A three-dimensional finite element method to analyze the structure-foundation-soils interaction has already been described in the previous paper. In this paper, we have proved that a large amount of differential settlements are caused by the shear settlements that occur in soils during construction of buildings. Based on this results, we have presented an analytical model to represent approximately the progress of construction of R. C. frame structures. And further, we have analyzed the settlement process of structures during and subsequent to construction by the finite element method using this model. The factors involved are plan of structures (square type and rectangular type), sort of foundation (raft and friction piles), horizontal extent and depth of poor grounds. The principal results are summarized as follows : 1) The relative deflections experienced by structural members vary with location and level in the building. 2) Although the modes of differential settlements of structures founded on the friction piles are similar to those founded on the raft, the magnitudes of the former are less than those of the latter. 3) The horizontal extent of poor grounds does not influence the differential settlements of structures as much as the depth of its does.

The objective of this study is to develope the improving method for the bearing capacity and deformability of PHC piles. In part 1, the experiments of the currently used PHC piles were carried out, in order to investigate the seismic behavior. As the results, it was found that the currently used PHC piles have less deformability and that the deformability could not be improved, even though the value of parameters of PHC pile was varied. Therefore, the condition of the a seismic design of PHC piles would be limited within a extremely small deflection range. And the necessity to improve the bearing capacity and deformability of PHC piles was reconfirmed. Then, a definite method was investigated. That is, it was analytically proved that the brittle failure, even under the limit magnitude of axial load, could be avoided, if the hollow part of PHC pile would be filled with concrete and furthermore, the core concrete would be confined by the plenty of spiral hoop. The experiments of PHC pile whose hollow part is filled with concrete and the analytical approach will be made in part 2.

This report describes on a comparatively large reinforced concrete office building the result of long-term investigations into the sagging damage to its floor systems while it had been in service for about 25 years though repaired and extended after the first 1/4 roughly of that period. The five-storeyed construction framed with girders and columns, soon after its execution, started to develop floor deflections which had gradually increased until about six years after when a large part of the slab panels had been cracked and subsided by considerable amounts. To have the structure repaired so as to be restored to an assuredly stable state, the load-bearing capacity of one typically damaged slab was checked by a water-pressure loading test with the result that the other cases were also judged to reserve sufficient strengh safely to sustain maximum amounts of service loads then prescribed, and thus the subsided slab surfaces were levelled off with epoxy resin mortar and where practically required H-beams were fixed to girders across such slab panels to brace them. The eventual conditions of the floors of the repaired building, with a subsequent extension built thereon having slab-beam-girder systems, investigated just before its recent demolition, are provided in available detail. Also reference is made to primary causes of such slab injuries : they are most probably be ascribed to the want of slab thickness designed in the absence of pertinent code provisions and also to the construction process involving significant degrees of dimensional inaccuracies.
