This paper is described about the failures of waterproofing membranes for underground structures applied on earth retaining walls prior to wall concreting. In this waterproofing system the quality of waterproofing work may become worse and failures increase because waterproofing membrane is applied to irregular surface of the earth retaining wall, waterproofing work is complicated with demolition work of earth retaining wall and concreting work. So it must be recognized the note of this system and needs to make standard of this system. Before standardizing, we researched the failures of this method and classified.

The life of the nailed joints that are used at shear walls of wooden houses was predicted by using the eyring model. In this study, the stress factors for the eyring model were the temperature of surroundings and equilibrium moisture content (EMC) of the wood in which nails were driven. And the constants of the eyring model were decided by accelerated test. The temperature and the relative humidity inside of the walls of wooden houses were measured, and the EMC of the wood were calculated.
By application of the eyring model, it was calculated that the life of the nails without surface treatment were about 230-370 years in the walls of wooden houses.

In this paper, we study the influence of ground motion predicted for Uemachi Faults to the response of highrise buildings. Two highrise buildings were modeled to fishbone-shaped frame model and time-history analysis was performed. Then, we compared response of fishbone-shaped frame model with response of other vibration models.Also, we studied the influence of PΔ effect. As a result, the following conclusions are obtained. 1) The response to the predicted ground motion is much larger than that of the seismic design motions. 2) It tends to evaluate the response small in a more detailed vibration model. 3) When the first mode response is predominant, the influence of PΔ effect is large.

The engineering plastics, polycarbonate resin materials are transparent and have a high level of impact resistance and flame retardant properties.
These properties enable them to be used as construction material in various ways. They do not break easily compared to other wooden building materials and are thus safe to use. This, in turn, leads to thinking that it may be possible to make a wooden shear wall consisting of plywood and nails like regular wooden-frame structure, with the exception of using polycarbonate solid sheets as a substitute for the plywood. Number of shear wall specimens were prepared and tested for in-plane shear properties.

The buckling-restrained brace is a brace whose core plate is covered with a restraining part to prevent buckling. In this study, two types of buckling-restrained braces are tested and evaluated. Welding a pair of mortal-filled steel channels forms the restraining part of one type. The restraining part of the other type consists of steel channels and flat steel plates with high-strength bolts. The restraining parts are designed to have an equal geometrical moment of inertia that is used as a variable in imposing buckling restraint. Then, the hysteresis characteristics, final fracture shape and cumulative absorbed energy are investigated.

With concerns about dependence on fossil fuel and emission of carbon dioxide, a concept of Solar Power Satellite was proposed by Dr. Peter Glaser in America, 1968. The concept is to construct huge solar cell panels in space and send electric energy to earth as micro wave. It was planned in America and in Japan around 1980 as structures whose scale extent is from several hundred meters to kilometers. This thesis will focus on the problem of transportation and construction of such huge plane panel structures and propose how to fold and deploy them two-dimensionally and stabilize it.

Underground wall is one of useful techniques to reduce the ground vibrations generated by artificial sources. To study such effectiveness of underground wall, forced vibration tests using a shaker were conducted in the construction site where the soil-cement wall was constructed. The experimental results showed that underground wall can considerably reduce ground vibrations just behind the wall. It also showed that the effectiveness depends on frequency component. In the present research, 3-dimensional finite element method combined with thin layer model was successfully employed to simulate the tests. As well as the field tests, the analysis demonstrated the effectiveness of underground wall in reduction of vibrations.

The vertical edge insulation on foundation walls, the popular method for structures located in colder regions, is expected to spread across moderate and humid climate regions because of its insulation superiority in the hygrothermal environments found in crawl spaces. However, in the first year after completion of buildings, the hygrothermal condition in crawl spaces with insulation foundation wall tends to worsen, leading to condensation and heating load growth. We clarify the factors affecting the hygrothermal behavior in crawl spaces with insulation foundation wall and explore some possible improvements in these hygrothermal environments through simulating simultaneous heat and moisture transfer.

Aiming to create a low carbon society, the most important task is to reduce energy consumption for hot-water supply which covers 1/3 of the total energy consumption in the residential sector. It has been considered that the introduction of a solar thermal system is one of the key solutions, however, its adoption rate remains sluggish recently in Japan. On the other hand, the installation rate of solar water heaters in China is amazingly high and now China has the world’s No1 share of the market. This paper is to report the outline of the research results on the present situation of solar hot water systems in China and its background in order to find new incentives to promote solar thermal systems in Japan.

Dealing with remodeling plan, we have to take actual building usage into consideration in remodeling plan and design appropriately from the point of further reduction of carbon dioxide emission or energy saving. In this paper, results of investigation study are shown. It was found that operational state of newly installed system is vastly improved in comparison with former system.

The LCA database for buildings (established by the Architectural Institute of Japan) has been developed and utilized to evaluate the reduction of environmental load through the use of wood materials. However, this method does not evaluate the environmental load incurred through the production and transportation of imported wood materials, although wood materials are imported into Japan in large volumes. Therefore, this study aims to develop a database which includes the environmental load of imported wood materials from several countries and regions.

The software outputs the temperature and the relative humidity of glassed-in spaces after users input the date, the location, the layout of those spaces (dimensions and direction), the specification of surfaces (roof, four walls, and floor), the setting of floor heating and the condition of natural ventilation.
Compared the predicted temperature with the actual measured temperature of a real glassed-in space, it appears that the software is a practical tool for understanding the overall behavior of thermal environment of glassed-in spaces, or for comparing the characteristics of thermal environment of those spaces under different input conditions.

In this paper, we report the result of some experiments about measurement of lateral load on balustrade caused by various human behaviors. We classified human behaviors in both ordinary and refuge-taking case, experimented to reproduce these human behaviors and measured loads of them. Compared to similar past researches, we roughly acquired appropriate results. Based on result of this experiment, we proposed the grades for the strength of balustrade, which should be expected to complement existing standards.

This research studies the application of the evaluation technique of thermal comfort in the outer spaces of urban areas, focusing on thermal environment evaluation indexes, i.e. HIP, MRT and thermal storage (thermal insulation), to the heat balance simulation tool in cold regions in Ulaanbaatar, Mongolia, climatically characterized by extreme cold and dry where urbanization is rapidly spreading. In addition, the research presents whether the environmental design of city blocks using the heat balance simulation tool in cold regions will help restrain the consumption of resources and reduce environmental burdens, and the methodology and the concept of creating living environments.
This paper reports the research frame and technique to apply the heat balance simulation tool, which was developed as a design support and environmental design tool mainly for reducing the heat island effect and cooling the city, to the cold regions, the results of a field survey on the information about buildings and the surface of the ground, and the collection and preparation of data required to perform heat balance simulations.
