In the previous report (1), a new method of composing Sandwich Curtain Wall is proposed. The Curtain Walls are made in the following way. 1. Steel-bar-grid is attached to the structural frame. 2. This grid is sandwiched between two special concrete plates. 3. These two are combined by concrete set between them. This experimental study is conducted on composing the Sandwich Curtain Wall under the following two cases. 1. Both sides of Sandwich Curtain Wall are composed by special concrete panels. These panels are made in our laboratory. 2. One side of Sandwich Curtain wall is composed by special concrete panels and the other sideis composed by tile panels and wood panels. The tile panels are used at the under half of the side and the wood panelsare used at the upper half of it. The results obtained are as follows : 1. The weight of a panel is only 6.1〜6.7kg. 2. Process of making each panel is simple and it is fitted mass production. 3. According to this method of composing Sandwich Curtain Wall, panels can be connected firmly and set precisely in its position. 4. The work of seting panels can be done even by one person. 5. This method of composing Sandwich Curtain Wall is easy, exact and rapid. 6. In this experiment the length of steel bars attached to the structural frame were 1.81m. This method is however practicable with in the steel bar length of 3m.

The strength, rigidity and ductility of the T-stub moment connections are investigated by the experiments. The experiments are consisted of three parts; the simple tension tests of the T-stub and the connection tests with two types of specimens (one for the case of vertical load and the other for the case of lateral load). In this experiments the behaviour of the high strength bolts are mainly investigated, but for the comparison of the fastener, welding and rivets are used. Also the effect of the rib-plate of the T-stub is investigated. The main results are as follows. The high strength bolted T-stub moment connection is good for usual rigid frame, judging from the strength, rigidity and ductility. At the high strength bolted T-stub moment connection, the load at which separation between the connected plates occurs at the bolts is usually smaller than the initial tension of the bolts, under the influence of the flexure of the connected plates. (In this experiments the thickness of the T-stub flange plate is same as the diameter of the bolts, so the separating load of the tension bolts is about 70% of the initial tension of the bolts.) The stiffening effect of the T-stub for the panel zone of the beam-to-column connection, which is very important part of the steel skeleton in the case of lateral load, is not so great. The effect of the rib-plate of the T-stub is not so significant.

The bond strength of TRICON, high-strength deformed triangular bar made by Kobe Steel Work Ltd, is compared with that of high-strength deformed round bar and also that of high-strength round bar in beams and columns. The results of the test are as follows. 1) TRICON has the same properties of bond strength as high-strength deformed round bar. 2) In the test, both TRICON and deformed round bar are pulled out of the concrete specimens by gradually breaking them. 3) When the concretes are reinforced up to the limits (1.5d and more than 2.5cm) provided by the standard, the allowable shearing strength of the test specimens does't depend upon the bond strength of reinforcements but the shearing strength of concretes. 4) Round bars are pulled out with out cracking concretes. 5) The bond strength of round bars almost attained allowable bond unit stresses for long sustained loading. This result is considered to be significant.

Present Accident Services in Our Country are not adequate to deal with the continually increasing numbers of serious accidents. It is significant to consider planning of systematical accident services in aregion. This paper deals with the case-load by Labor Accidents in the area in order to design an accident Service even at regional Level. Thus, The following were Surveyed. (1) The case-load by Factory, Coal mining, and Other Industrial accidents. (2) Corelation to Distribution of Labor and Medecal Facilities for Labor Accidents. (3) Utilization of Medical Facilities for Labor Accidents by Labor Accident's case. (4) Utilization of Other Medical Facilities by Labor Accident's case.

In the foregoing report, it showed that "Honto-cho" was the data-book for estimation for building houses, and it was edited and used by "Daitoryo", who was the chief carpenter under "Edo-Shogunate", from the middle "Edo-era" to the end. "Honto" was the standard price of commodity and the standard labor and wage of construction works. The biginning of use of it coincided the consolidation of "Sakuji-kata", "Kobushin-kata" and "Kanjo-kata". The cause of use of this data-book had relation with social and economical conditions, and it was made to settle the rise in price of commodity or wage. Standard price arose from the fixed price originally in a contract for ten years. This data-book "Honto-cho" had similar contents to "Kanjo-cho" or "Sho-zumori" in "Gushikenki". Therefore, "Honto-cho" should be contained in "Daiku-gijutsu-sho" as the book of technique of estimation for building houses.

It is the most essential for the interior of Zen style to have the undersurface of pseudo-pitch-roof open up and to reveal the inner structure. Rainbow-beams, bottle-post, inner lever arms of eaves brackets and lobster-beams constitute the structural features of Zen style. These structural features and the lofty interior greatly influenced Japanese traditional style through the middle ages (12-16th century). As a result of this, one of the flowering periods for the Buddha halls came in Japan at that time in its development of the interior design. But there are still something obscure in the structural features of each type which can be classified according to the number of bays, because the inner structure of Zen style is regarded as quite fixed and the features of Buddha halls of the main Zen monasteries have not been made clear. The aims of this paper are to define the structural features and the characteristics of the interior of each type and to study the relation and influence on Buddha halls of Japanese traditional style.

The earthquake which occurred on April 20, 1965 in Shizuoka Prefecture, was not so severe but only moderate and caused minor damage to wooden houses, roads, railways, etc. However, the most remarkable damage caused by this earthquake was the failure of window glass in some reinforced concrete buildings, and the question has arrisen what the main reason for the failure was. This report presents the results of investigation including the damage inspection, the measurement of natural periods of buildings, the estimated interstory displacement, etc. It is concluded from the investigation that the glass with high percentage of failure has something in common with "steel sash", "fixed" and "hardened putty". This means that because of "fixed" the deformation of structure was directly transmitted to the sash, and because of "hardened putty" there was no clearance between glass and sash. It was first considered that the failure occurced becouse the large amount of interstory displacement due to long natural period determined the large displacement to window glass. However, the period measurement revealed that the damaged buildings did not have a very long period, and the estimated story displacements are ranged between 1/5000 and 1/1000 in angle which could have been absorbed if there was some clearance between glass and sash.
