    This paper describes the result of long-term crack-inducing experiment on half-scaled four RC wall specimens. Compared to conventional crack control joints, the proposed crack control joints with crack-inducing bars could contribute to inducing shrinkage cracks within the joints more uniformly. As a result, the maximum crack width in the joints with crack-inducing bars was smaller than that in the conventional joints. A crack width estimation method proposed by Ohno et al. could accurately estimate the maximum crack widths of the specimens.

    The floor slabs directly above footing beams are parts of a reinforced concrete building that require insulation. A construction method using thermally insulating extruded polystyrene foam, which does not require removal, is frequently employed to simplify slab formwork dismantling in the underground pit.
    Foam formwork has different mechanical characteristics to plywood formwork. However, these characteristics are still not well understood.
    In this study, the stiffness of polystyrene formwork is evaluated by conducting bending and bearing pressure tests using a component specimen. Moreover, a full-scale experiment is conducted under the loading conditions present during actual construction, to investigate whether the true deformation can be assessed based on the stiffness value obtained from the component tests.

    This paper discusses a measurement method of unit weight and water content of concrete using radio isotope meter. Concrete members with different unit weight were measured them at the age of 7, 28 and 91 days. As a result, it was found the following things. If the unit weight of concrete is high, the measurement accuracy of the unit weight and water content using radio isotope meter is low. Inserting the radio isotope source a sleeve, it can reduce variations in measurements. The drying of concrete read from radio isotope meter. The calibration curve between the unit weight of concrete and the attenuation of radiation was created.

    For a further improvement of formwork construction, it is necessary to know actual state because of the important role of the formwork contractor. Therefore, the purpose of this study is to reveal the actual state about component materials and erection of conventional formwork by the questionnaire survey targeted to formwork contractors of Kanto and Kinki area. As a result, this paper showed the actual state of formwork construction about structural calculation for strength and rigidity of formwork, erection type of formwork by studs and separators, regional characteristics of component materials of formwork.

    A small-diameter drilling tester developed by the authors is one of the slight-destructive testers, with which the damage of materials tested can be very small. To apply the tester for checking the strength of compound materials e.g. Portland cement mortars, concretes etc., a series of experiments was carried out 1) to avoid the ill effect of cement powder discharged around a drill, 2) to avoid drilling coarse aggregates, and 3) to know the best magnitude of pressure for drilling. As a result, it is clarified that the testing method may be improved by considering the obtained data.

    We have investigated three actual RC buildings, which were built about 50 years ago, to clarify the carbonation inhabitation effect of the finishing mortar on the progress of concrete carbonation. It is found from this investigation that the differences of carbonation progress between the concrete outside wall in one orientation and that in other orientations can be evaluated in carbonation rate coefficient. The investigation of durability of other actual RC buildings should become more accurate with the simplified analytical method described in this paper.

    This study surveyed evacuees from Miyagi, Japan after the Great East Japan Earthquake to elucidate their living environments and intentions. Comparing living environments among various types of temporary housing, their levels of satisfaction differed. Over half of the residents of prefab housing were the elderly and economically vulnerable people, who were highly dissatisfied with their living situations. Among them were households living apart from their families due to space limitations. However, homeowners who wished to rebuild their damaged houses tended to be younger and have higher annual incomes than those who preferred to keep living in public housing for evacuees.

This research examined the psychological effects which window lights have on external pedestrians and neighboring residents. The experiment showed that the warm color window lights located in the first floor whose inside can be seen tended to improve various effects to the pedestrians who are in the street. The interaction was confirmed only by the position of the window, and the color of light. Evaluations of suppression of dumping garbage, etc. rose remarkably with the window of warm color light on the first floor.

This study investigated facility residents’ preferences for bedroom types through a questionnaire survey in Shanghai. The results suggested greatly separated preferences for private bedrooms and double bedrooms, which were significantly related to respondents’ gender, former occupation and marital status. Moreover, elders’ opinions on bedroom sharing indicated distinct values regarding collectivism and individualism. The results are expected to further the understanding of Chinese elders’ concerns about spatial privacy, thus benefit the architectural planning of relevant facilities.

    This project challenged to stress the characteristic of natural environment, such as the Tama River, abundant green and strong wind peculiar to the location at the Futakotamagawa Rise's pedestrian passage. 2,000 swinging sheets reflecting ambient lights were attached to the trees or the stairs. The road surface was illuminated with the blue lights which remind the Tama River, and the ripple of water was projected on the bridges. As a result of the implementation, sensational evaluations of natural environment have been improved. In addition, where the visitors have conducted a workshop to install lights, emotional attachment to the place has increased.
