The author this time offers the measuring scale for grading sands in 1 week mortar strength. According to this scale the result well aggrees with that of by the 4 week test, which is already shown. In order to detect that scale he prepared a pair of test groups. Each group is composed of two-way-layout experiment (sand)×(water-cement ratio); 2 test pieces are formed from every mortar mix, one for 1 week test, the other for 4 week. The strength of the above two samples corresponds each other in conformity to the respective age. Analysing the two sets of data apart, comparing the variances of the experimental errors, testing the significancy of the factors and the significant levels, he arrives the conclusion that the 4 week scale should be modified for 1 week by the ratio of the respective standard deviation of the two experimental errors, because the original scale is derived from the population standard deviation of the error in 4 week test. At last he applys the acquired scale to the 1 week data and shows the result well aggrees with the 4 week test. Thus we can grade sands through 1 week mortar test.

This report deals with the analysis of the deformation and stress distribution of seismic wall, as a plane stree problem, by a lattice analogy using the element shown in Fig. 1 (c). Firstly, to demonstrate the accuracy of the method are selected three examples which were obtained the exact solutions or the results by the experiment, and then the method is applid to the free standing seismic wall which has three stories. Conclutions were obtained from these investigations are as folows; From the check of the method, except the parts in which has irregularities, it appears that a relatively coarse mesh can give good results, and it can be made the error under 3 percent in general. For the seismic wall, 1) The wall takes about 90 percent of the shearing force in each story. 2) At the center line of wall, the value calculated by the elementary theory seems to give more good results for the shear deflection rather than for the deflection by bending.

This building has been designed in the form of a composite construction of steel and reinforced concrete and is featured by its shear walls which are to act as the principal load carrying elements. For the purpose of this structural design, the known data on buildings' response to earthquakes have been referred to, and then, further in the course of design, the rigidity of the proposed structure has been computed and the analysis has computer to determine the linear load-defermation relationship. The results thus obtained have been adapted to been made by the aid of SERAC analog computer to determine the linear load-deformation relationship. The results thus of tained have been adapted to the anticipated deformation in plastic range. Because of the absence of the records of strong earthquakes in the site of the building (Takamatsu, Shikoku Island), the wave patterns of E1 Centro, Taft and Saitama earthquakes and that of Echizen-Oki earthquake as recorded in Kinki Region, which are all commonly used for this sort of purpose, have been adopted for this response analysis. (The maximum acceleration due to the foregoing earthquakes has been taken at 0.33 of the acceleration due to gravity.)

The critical stress for an ideal spherical shell under uniform external pressure is given by the formula [numerical formula]. It is almost four times greater than the experimental value. In putting forward their explanation of the discrepancy between experiment and the classical theory, Th. Von Karman and others made the assumption that a "jamp" or "snap" into the buckled state is possible if the shape of the shell is imperfect or if the applied pressure is pulsating. However, these theorys did not suceed in giving a satisfactory solution to the problem of determining the minimum pressure in a non-linear state. In the exposition of this question we shall follow our energy method. Intreducing the notations II_0: Total energy in the first form of equilikrium. II_1: Total energy in the additional condition of equilibrium. y: Unit additional displacement. We set up the expression △II=II_1-II_0, if u_1 and w_1 is the symmetrical additional displacement for the axis, and taking expressions for the conditions with the stable and unstable states of equilibrium merge into one state, namly setting: (2:11). Besides, we set up the expression (5:11) that the additional functions ξ(φ) and η(φ) satisfying the equation (2:11). Results of calculations carried out for values of σ_<ck>, we also found the value: [numerical formula] Secondly, we setting (5:11), and we obtain: [numerical formula].

This report describs a method of calculating temperature and heat flow through a combined wall when the former two are in a periodically steady state. In this method, we use impedance matrix which is defined as a system function of the temperature and heat flow on one side of the wall to those of the other side. Temperature and heat flow over every section of a combined wall, as well as each element of the impedance matrix, are represented by complex vectors instead of sine waves. Therefore, in preparing a table of elements, both the absoluts and the arguments, we can easily caluculate temperature and heat flow through a combined wall when they are in a periodically steady state.

The villages in the reclaimed zones of Saga Prefecture can be classified in four types, namely scattered, linear, gathered and agglomerated villages. But in the last ones the dwelling houses and other structures are gathered in a lagge scale. Historicaly, the villages in the reclaimed zones have been erected from Kamakura era to nowadays. The scales of the villages; Scattered villages; 10-90 farm houses. 59% of the examples in 20-40 farm houses. Linear villages; 20-90 farm houses. Most examples in 30-50 farm houses. Gathered villages; 10-90 farm houses. 76% of the examples in 20-60 farm houses. Agglomerated Village; This is consisted from many gathered villages, 84% of which have 30-60 farm houses. The areas of dwelling lots; Scattered; 130 Tsubos. (390m^2) Linear; 130 〃 (〃) Gathered; 150 〃 (450m^2) Agglomerated; 106 〃 (318m^2) Sistances of farms from farm houses; Scattered; The farmes diminish as they are farer. Linear; Most farms are 500m〜1,000m. Gathered; Most farms are in 500〜1,000m. Agglomerated; The farms increase as they are farer. The areas of farm lots; Scattered; 3.54 Tans. (0.35 hec.) Linear; 2.36 〃 (0.236 〃) Gathered; 2.26 〃 (0.226 〃) Agglomerated; 1.83〃 (0.183 〃) Generaly the area of one farm lot is verly small but farm lots must be gathered in a large seale modernize the agriculture. Usage of farm machines; Farm machines are used generally in these zones, but in gathered and agglomerated villages they are in common use in high order. This indicates that the co-operation of farm machines can be more promoted in gathered and agglomerated villages than in others.
