An experimental formula to estimate the solid content of combined aggregates with the fine and coarse aggregate specified in JASS 5 is proposed by means of the Grading Parameters on the FM scale that one of authors has reported in the previous paper and the solid content of the fine and coarse aggregate as the components, provided that the solid content of combined and component aggregate is measured in the same mode of packing; i. e., container and packing efforts such as jigging, rodding or shoveling procedures. This formula is able to calculate the solid content of combined aggregate of sand or crushed sand and gravel or crushed stone respectively, and will be used for rationalizing the design method of concrete mixes applying to C. T. Kennedy's Workability Factor.

Cracks produced in concrete will cause active-passive cells to be formed at reinforcing steel in the interior. There are many instances where allowable crack widths have been studied and reported from the viewpoint of durability, and in order to study the results when the influences of chlorides and environmental conditions, and the effect of zinc coating are additionally taken into account for the cases of these reports, outdoor exposure tests were conducted on specimens cracked beforehand. Further, with the aim of confirming the results, repetitive wetting and drying tests were carried out on similar specimens. As a result, the following were clarified : 1. Allowable crack widths for durability when using ordinary concrete and ordinarily-treated reinforcing steel under ordinary environmental conditions are as indicated below. Cases of No Chloride Content W/C=0.45-0.65 0.1mm Cases of Chloride Content W/C=0.50 0.1mm regardless of chloride content W/C=0.60 NaCl=0.04-0.1°/sand 0.1mm NaCl=0.12-0.2°/sand 0.05mm NaCl=0.3°/sand 0.02mm At seashore districts and cold weather regions the allowable limits are roughly the same as above, but in industrial districts (SO_2 concentration 0.05ppm (annual average) or higher), it appears 0.5 times the above values may be considered. Further, the above will be applicable to concrete cover of up to about 80mm. 2. It will be necessary to establish design, mix proportions and work execution methods in accordance with environmental conditions in order to improve durability of reinforced concrete. 3. Zinc coating, if sufficiently sound and uniform, and if well-bonded, may be expected to provide corrosion preventive effect for substrate reinforcing steel.

The purpose of this study is to clarify the effect of pile diameter on the base resistance of nondisplacement piles in sands. Experiments were carred out systematically by model piles in the pressurized tanks. The test results were compared with full scale test results of non-displacement piles (bored piles), and also plate loading test results at the bottom of a borehole in sands and gravel.

The entitled case of structures refers to one of the cases discussed in the preceding report in which results of the analysis of three types of staircases were compared with the corresponding experimental results, as a part of studies on the method of the structural design of the reinforced concrete staircase composed of either a set of slabs or a helicoidal shell. With regard to free-standing staircases it was then confirmed that the ratio of the elastic limit to the ultimate strength of the structures decreases with the increased angle between the horizontal projections of the inner edges of their pair of flights. In case of having this angle null while varying horiontal distande between both flights of a staircase, that then lie parallel in plan, elastic and vibration analysis of the structure are presently made using the finite element method so as to clarify major characteristics of its statical and dynamical behaviors. Then these results results are used in proposing some approximate design formula that may generally be available for this type of staircase.

The previous paper (Part 3) proposed a method to determine an optimum distribution of the cross sectional areas of members in a structure so that the structure sustains uniform plastic deformations in all the members during earthquake excitations. If situation is so that the distribution of Plastic deformations of members is controable, the magnitude of uniformly distributed plastic deformations depends on a total volume of structural steels used in the structure and, therefore, the volume of structural steels should be so determined as to limit plastic deformations within allowable values. The present paper described a systematic approach for determining thevolume of structural steels on the basis of the energy absorption capacity of all the members in a structure and energy concept introduced by G. W. Housner. This paper first analyzed internal work-maximum strain relationships of a member under monotonic loading, with which the energy absorption capacity of the member was determined basing on the strain when local instability of the plate elements takes place. A convenient method was devised with which it is possible to calculate, without resorting to a dynamic response analysis, a reasonable approximation to the total input energy into a structure under carthquake excitations. The total energy is equal to the input energy due to the ground motion plus the work done by the dead loads. Basing upon these calculations and under the assumption that the input energy is absorbed equally by all the members, an optimum volume of total steels in a structure was obtained.

As an application part of the preceding papers (III) (IV), in which an evaluation method of the aseismic capacity of steel structures with symmetric and asymmetric braces was proposed, in this paper, the aseismic characteristics of such structures and the aseismic effects of bracing elements are investigated on the basis of their resonance-fatigue-characteristics. The aseismic characteristics of bracing elements and of structures with symmetric braces in plan are shown in the λ-η plane (Fig. 7) and in the γ-b plane (Fig. 9), respectively. The resonance-response behaviors of structures with asymmetric braces are calculated and presented in Fig. 18 as case studies. Concluding remarks are that bracing elements are effective enough to make steel structures rigid type which resists erthquake excitations through capacity and that there still remain some unbalancing risks even if two bracing elements are arranged symmetrically and separatively far from one another.

This paper is the last part of five serial reports and consists of two sections. In the first section, an equivalent linear model is proposed to develop simpler analytical model than those used in the computer program OS-1D in the previous papers. The proposed model consists of (a) a tetra-linear skeleton curve having origin-oriented histeretic rule and (b) equivalent viscous damping ratio depending upon the experienced maximum response displacement in terms of ductility factor. It is indicated that the proposed model analysis can simulate well the maximum response displacement obtained by the On-line test. In the second section, the overall view and results of the project are summarized.

The purpose of this study is to explain the influence on the audience's age and range of a civic hall by its location and performance in osaka. The method of this survey is mesh analysis. The conclusions are as follows : 1) average audience's age : 20〜30 ages in a orchestra concert, 35〜50 ages in a Japanese traditional entertaiment. 2) The pyramidal shape of the audience's age has four kinds : star shape, gourd shape, pot shape, opposite-pot shape. 3) The hall location gives a pattern of the audience's range. 4) The kind of a performance determins the scale of the audience's range. 5) The distance from a hall to the center of osaka mostly determins these : the ratio of audiences per a thousand population and the accumulation curve's pattern.

This study deals with an analysis of occupant behavior in an office building under fire and continues from the previous paper of (Part 1, Classifications of Behaviors). In this paper, the interrelationship between three items of a) Occupation and Sex, b) First Action After Perceiving Fire and c) Evacuation Behavior has been analyzed to find out characteristic behavior patterns. And mutually related categories between the three items have been selected by using the quantification theory of Case 3. As the result of analysis, two types of behavior patterns have been extracted. They are the behavior of store owners and male store clerks of the building's shops and restaurants to (F_1) take responsible actions when they perceive a fire and then to (E_1) escape via the route that they previously decided to take in fire situations, and the behavior of female office clerks of the companies in the building to (F_4) wait for superior officers' instructions when they perceive a fire and then (E_5) escape by following instruction and guidance. But, since most of the occupants take F_3 (call to others to escape together, remove valuables or waver in confusion) as "First Action" and E_2 (take a shorter route or choose a route instantly) or E_4 (run after others) as "Evacuation Behavior", it is more appropriate to conclude that in a fire situation of an office building, people take F_3 and E_2 or E_4 behaviors latently and among them, those who are in the position of feeling professional consciousness strongly will take peculiar behavior patterns as F_1 to E_1 and F_4 to E_5.
