    Properties of expanded shale aggregates are discussed in the preceeding report. This report describes results of studies on lightweight concretes made with these aggregates. In addition to 2 expanded shale, normal sand-and-gravel and Haruna pumice are used for a comparison. 2 kinds of concretes, high and low slump, are mixed. One of their slump is 19cm, for normal cast-in-place concretes and another in 5cm, for pre-cast concretes. Cement contents, fine-to corse aggregate ratio and air contents of fresh concrete are decided by trial mixes. Properties of concretes which their cement contents ranges from 250〜400kg/m^3 are tested. These tests include unit weight of fresh concretes, dryed weight, compressive and bond strength, modulus of elasticity, drying shringage and freezing-thawing resistance. Although there are some differences between 2 expanded shale concretes, test results are approximately as follows. i. These concrete weight are 1.3〜1.5kg/l and are 60〜70% of normal weight concretes. ii. These compressive strength are linear to cement contents and 150〜220kg/cm^2 concretes are gained by using 350kg/m^3 cement contents. iii. These modulus of elasticity are 1.1〜1.4×10^5kg/cm^2 and about 60% of normal weight concretes. iv. These drying shrinkage of 60 days are 0.05% and are smaller than the others. v. Freezing-thawing resistance corresponds to total water contents and one of expanded shale concrete are as strong as normal weight concretes.

  • STANDARD SPECIFICATION FOR REINFORCED CONCRETE WORK IN COMPLIANCE WITH THE DISADVANTAGEOUS CONDITIONS IN THE DISTRICT OF KAGOSHIMA PREFECTURE

    This is the successive report to the previous one. Here, three main items are picked up; various conditions of aggregates, A.E. concrete mix, broken stone concrete mix, both plain and air-entraining. (1) Conditions of aggregates. The whole mix table is first systematized in absolute volume mix. The other methods are derived from it by culculation according to the conditions of the aggregate, which is somewhat different from normal one. Statistical and empirical data on specific weight, percentage of absolute volume, standard and field measuring are given. The ground of the culculation will thus become clear. (2) A.E. concrete mix. The mix table is shown in the previous report. The way of modifing the Standard-mix and of getting A.E. mix are explained. The JASS method of modification is available in this case. We lessen 8°/wt of water and decrease sand in plastic mix. Stiff concrete of 5, 10cm slump is obtained directly by experiment, for we have no such mix in the Standard-mix. (3) Broken stone concrete. a. Consistency of concrete is different according to the grading of the broken stone even within the allowable grading limits. To get concrete of better consistency coarser grading is advantageous. b. Water should be added 8〜12°/wt to the Standard-mix. This is different from JASS and it is proved to be harmless to the strength. c. B.S., A.E. concrete can be got following JASS, lesseing water 8°/wt from plain concrete in plastic mix. Stiff mix was made through experiment. The mix table is shown to the end.

  • GENERAL SOLUTIONS OF SPHERICAL SHELL IN STATE OF FREE VIBRATIONS (2)

    To calculate the frequencies of free vibrations is very bothersome, but from the characteristic values concerned with oscillatory solutions the character of oscillation, and insufficiency of many other approximation methods can be shown. If we set order of Legendre function as follows, [numerical formula] we can get the following three dimensional polynomial of λ from the expression of stress function. λ^3+{4+(1-ν^2)Ω^2}λ^2+k(1-Ω^2)λ+k{2+(1+3ν)Ω^2-(1-ν^2)Ω^4}=0 and from compensated solutions λ_4=-{2+2(1+ν)Ω^2} λ can be considered as characteristic value of free vibrations with parameters [numerical formula] 1) λ: plus real number monotoneous damping 2) λ: minus real number harmonic (non-damping) oscillation 3) λ: complex conjugate oscillatory damping It becomes apparent with these values λ_i that to neglect the inertia terms occured by displacements u, v, to approximate as inextentional or extentional vibrations are nonreasonable, and lowest frequency may be assumed as near value of Ω^2=1. Finally, we may find the approximation of solutions, with which we can calculate free vibration frequencies rather easily.

    In this paper, the analysis on spaced truss composed of square pyramid units is imformed. This spaced truss has two layers. The upper layer is diagrid and the lower is grid frame-work. The joints in the upper and lower layers is tied each other with lattice members. This report consists of three parts. First, the stability of the spaced truss is discussed. It is very interesting to investigate its stability, for the number of members which the unit of this truss has, is smaller than that of other trusses which is usually constructed. Second, there is reported concerning to the calculation method of the deflection and the stresses of truss members. This method will be troublesome to calculate the deflection and the stresses, if the number of members increases, but the results are got accurately. Third, there isreported the another calculation method. By this method, the results are obtained easily, but its accuracy is inferior to the previous one. (Proceeded)

  • THE STRENGTH OF TRUSS JOINTS IN TUBULAR STRUCTURES : Part 2 Influences of Variations in Dimensions of Members and Welding Conditions

    A series of tests on the truss joints for tubular roof trusses have been continued, and this report supplies the results of the test in which the dimensions of the members meeting in the joints and the welding conditions were varied into some different cases. Though the manner of failure, of course, differed each other with the dimensions and combinations of all members meeting in the joints, the most dominant type in the manner of failure was the local deformations in the walls of chord members. Thus the magnitude of these local deformations and the strength of the joints were found to be affected greatly by the wall-thickness of the chod members. The other truss joints of which the local deformations in the walls of the chord members were not the causes of their failure failed as a result of tearing tension diagonals or local buckling of compression diagonals. The strength of the joints which failed in these two manners were both related, more or less, to the net section strength of the diagonal members. Because the fracture in the welds seldom occurred in spite of the fact that the end of the diagonals were prepared by sawing in one (or two) continuous operation, it was inferred that the ends of tubes which were to be welded directly to the surfaces of the other tubes could be cut in the form of plane so long as the root openings were maintained within 3 to 4mm.

    The factors, which have influence upon the way of attaching the door, are numerous, but this paper reports how we have analyzed the result of the practical survey, which we have carried out, choosing chiefly the "turning angle" among three factors of the "turning angle" (the turning angle of the line connecting one shoulder with another), the distance of walking, and the time required, in view of the convenience and inconvenience based upon the motions of the human body at the time of the opening and shutting of the door, The present experiment has adopted the case where men enter, through a piece of the door with one leaf opening on hinges, into the sufficiently wide room from the long corridor. Moreover, the experiments were devided into the case where once the door was opened, men entered the room without shutting the door, and the case where men politely shut it behind them; and the results of photographing by the 8 millimeter-camera were analyzed.
