Test were performed for influences of impurities contained in mixing water for concreting which are natural or artificial water on the drying shrinkage of mortar or concrete. On the basis of the test results, consideration was made to set up a standard for examining mixing water for concreting. Test results are summarized as follows; (1) The drying shrinkage of mortar or concrete are affected remarkably by the concentration of impurities in the mixing water. (2) The concentration of 1, 000 ppm of impurities contained in mixing water is criterion for determining whether or not the water in question can be used as mixing water for concreting.

Forms of sliding form method are usually made of wood except yokes, and so in many kinds of literatures and past excutions. But forms made of wood usually deform when they are used, because wood absorbs water and so changes in length. Against such deformation the use of steel sheathing boards and steel wales is effective. The excution using metal forms as sheathing boards and channel steels or angle steels as wales was success. The general difference between wood forms and steel forms can be seen in past data. But, the difference in rigidity between these and those assembled is unknown. It is important to know this because the rigidity means how much accidental load the forms can endure under construction. The rigities of assembled wood forms and assembled steel forms were tested by means of using the full sized models. Steel forms assembled with 15cm wide metal forms indicated the smallest deformation. In case steel forms are used, it need not make the top of the sheathing boards incline inside because the deformation of steel forms is small.

In the first half, an opinion about factors indicating the Resiliency is reported. The outline of this opinion is that we must investigate the relation the dynamic deformation of the gymnasium floor to athlete's sense on resiliency. In the latter half, the process of planning and manufacturing by way of trial of apparatus for measuring the resiliency of Gymnasium floor is reported. By the experimental study on the translating the dynamic load, being acted on the gymnasium floor by athlete, into the mechanical load, we could obtain the mechanical load which was consist of Weight and Rubber Spring. making use of this mechanical Load, we manufactured by way of trial the apparatus for measuring the resiliency of gymnasium floor which was able to obtain the dynamic load-deflection curve of gymnasium floor. The result as obtained for the performance test of this apparatus is very efficient.

The research described herein was undertaken to observe the behavior of orthogonal space frames subjected to axial load and eccentric horizontal load. The objective of this experiments is to investigate the validity of this analytical method described in the previous paper and to observe the effects of axial load and the eccentricity of horizoantal load on the inelastic behavior of space frames. Ten model specimens were tested under horizontally eccentric loading and experimental results of some of the ten specimens are compared with the behavior predicted from the numerical procedure. For the ultimate carrying capacity, the agreement between numerical and experimrntal results appears to be satisfactory. From experiments and numerical studies, it is apparent that the ultimate carrying capacity of space frames composed of H-shaped members decreases greatly by the biaxial bending aed torsion of each column member resulting from the eccentric horizontal load, and the space frames under those loading conditions should be examined sufficiently.

In the former paper, the general method of analysis of aeolian vibrations was presented. It made possible the general discussions on analysis of aeroelastic vibrations of cylindrical structures. This paper discusses by statistical concepts the stationary solutions of the vibrations of cylindrical structures in natural winds. A model for analysis is a cantilevered cylindrical structure of which a typical case is a steel stack. The analysis is proceeded according to following factors, that is, the theory of random vibrations by A. Powell, strip theory, idea of the standard height to estimate natural winds, idea of the reference diameter and the reference velocity to be available for aeroelastic forces and the utility of analytical results. Thus, the solutions of buffeting and aeolian vibrations and the estimation of the beat phenomenon are indicated.

The method of analysis most commonly used for the earthquake response of structure is based on the vibration theory. For the simplest model of single-degree-of-freedom system, the equation of motion is written as follows : [numerical formula] in which ω^2=K/M and h=C/2ω_nM. Namely, the response characteriistics of the massis determined thoroughly only by the foundamental frequency ω_n and the damping coefficient h, for anf given earthquake ground motions. That is to say, the quantity of mass has nothing to do with the response characteristics of the system. These analytical results are often contradictory to actual behaviors. The amount of energy generated by a large earthquake may well be considered to be infinite at its source, however, energy density at a point several ten kilometers away from the source can not be regarded to be infinite. The energy balance between the energy supply by earthquake wave and energy dissipation within a structure must be taken into account, besides the above equation which is composed from the balance of forces. The dynamic response characteristics are analyzed on the basis of energy balance in this study. The additional condition due to energy balance is ΔW_i=ΔE+ΔW_r in which ΔW_i is the energy supply by incoming earthquake, ΔE is the energy dissipation within a structure and ΔW_r is the energy dispersed from the base of structure. As the result, it was proved that the influence of mass load of structure can not be neglected for the earthquake response estimations of actual buildings.
