This research has been made on the tensile behaviour of concrete, with an intention to provide data to clearify the conditions of crack occurrence in the concrete construction. The outline of the research content is as follows. 1. TENSILE TESTING METHOD The direct tensile testing method using a resin adhesive agent was devised and applied in the test, and good results were obtained. 2. TENSILE STRENGTH OF CONCRETE (a) The crashed light weight aggregate concrete having, as a rule, a small tensile strength in its material, shows a little in crease in tensile strength in the high strengh zone. (b) The pelletized light weight aggregate concrete sticks very poorly to cement paste because of its globular form, and has a constantly smaller F_t/F_c value compared with ordinary concrete. (c) The relation of tensile strength and compressive strength of ordinary concrete was compared with the results of researches made in the past, and it was found nearly in according with the experimental results of Dr. Kanoh. (d) When the tensile strength in the direct tensile testing method was compared with the tensile strength in the spliting testing method, both were comparatively in good agreement in the low strength zone, but the latter showed higher value in the high strength zone.

The distributions of the normal stresses, σ_x and σ_y, and the shearing stress τ_<xy> of three-storied walls with opening, under the uniformly distributed lateral loads acted on the upper surfaces of the beam of each story, are investigated in this report. The sizes of the wall and the types of the opening are the same reported in Part IV. The main results obtained are as follows : 1. The stress distributions at each story are resemble each other, except the neighborhood of the column base in the first story. 2. On the walls with the rectangular opening, the stress distributions in the walled girder are resemble to that of the widthwise opening walls, and in the walled column, of the lengthwise opening walls, respectively. 3. All of the stresses are affected considerably by the stress concentrations at the corners of the opening. Excepting the neighborhood of the corners of the opening, 4. σ_x : on the vertical section in the walled girder, σ_x disributes approximately in a straight line. 5. σ_y : Near the center of the column height, the inflection point (line) are produced in general, and at a short distance from this line, σ_y do not distribute straightly, and on the outside of the column σ_y distributes almost straightly in the direction of the height. 6. τ_<xy> : In the column top and bottom of the walls, having the rectangular or the widthwise opening, the large negative shearing stresses are produced.

This paper treats the wear by aging of asphalt-built roofs by selecting and examining their actual pieces in order to contribute to fundamental data for maintenance of buildings. Twenty-six telephone and telegraph office buildings aged from two to thirty-eight years were selected from all over the country and test pieces of asphalt waterproofing were picked out when the buildings were extended or repaired. They were examined about tensile strength of asphalt belt or roofing, and penetration or softening point of asphalt, etc. moreover, consequences of observation of outlook, etc. were added, the summary wear-degree was considered. As the result, the following conclusion was obtained. The relation between wear of 4-sheeted asphalt water-proofing and age is y=2.0t^<1.08>. If the remains were 20%, their longevity is considered approximately thirty years.

In Edo-era, the Ministry of Civil Engineering and Construction was named "Fushin-kata" and the Ministry of that office was "Fushin-bugyo". Being ranked with "Sakuji-kata" and "Kobushin-kata" (these two offices were the Ministry of Architectural Construction), it took charge of official construction work under "Edo-Shogunate". Therefor, in order to study the historical progress of estimation for building in Edo-era, it is also necessary to decipher and make clear the historical document concerning "Fushin-kata". In "Fushin-kata", they had a data book for audit of civil engineering and construction……for instance, road, bridge (wooden or stone-built), bank, stone wall, stone flooring, quarrying, turfing, clay carrying, etc. About these works, the standard labour, the standard wage or material cost, and proper quantity of material were indicated in a table. The name of that data book was "Fushin-kata-tsumoritate-teiho" or "Go-fushin-tsumoritate-teiho-gaki". It was made in "Kyoho-era" (1716〜1735) by Yasoemon Izawa who was an official of "Kanjo-ginmi-kata" that was the Board of Audit in "Edo-Shogunate". The technical skill for estimation for building in "Fushin-kata" was inferior to that of "Sakuji-kata". It was due to the fact that the civil engineering was more closely conected with nature than the architectural construction.
