Molten slag recycled from domestic wastes can be used as a fine aggregate in concrete but not currently applied in practice. This may be attributed to the lack of example concrete structures built using the waste slag fine aggregate. In this report, a construction experiment of full-scale concrete structure built with the recycled aggregate concrete is studied. It was shown that the recycled aggregate concrete can be applied to the concrete pumping construction under the same condition as that of the normal concrete and the resulting concrete quality in the structure was satisfactory. Practical application of the waste slag fine aggregate was proven to be promising.

In order to construct foundation beams using half precast concrete technique, authors have investigated to confirm the uniformity in the process of execution and the uniformity of structural members as finished products. The square test speciments without joint of the precast concrete forms have been manufactured by techniques of half precast concrete and in-site concrete, and its uniformity has been shown only by bending test. In this paper, bending test results and shearing test results of rectangular beams joining the part of precast concrete forms are discussed for test speciments manufactured by techniques of half precast concrete and in-site concrete. As the results of comparison, it is obtained that structural property of the test specimens with joint manufactured by technique of half precast concrete is very similar to the test specimens manufactured by in-situ concrete technique under the shearing force or the bending-shearing force. And also, it is not until reinforcing bars yield that the structural property is similar under the pure bending condition. Therefore, results of various tests of rectangular test specimens with joint using half-precast concrete technique are shown the uniformity of the half-precast concrete part and other part.

A linear formula on the amount of thermal expansion for the membrane and frame, which are used for waterproofing roof made of stainless steel membrane, was theoretically developed and the accuracy of this formula has been confirmed and verified by means of computation using the finite element method. As a result, it has been verified that the calculated result of this theoretical formula duly coincides with that of computation by the finite element method. By the application of this formula as well as the finite element method, the displacement of stainless sheet, frame and clip can be estimated and the tensile force produced in the axial direction of membrane, as a form of internal stress as well as the evaluation of maximum length can easily be estimated and evaluated.

This paper describes the feasibility of recycling of aged waterproofing materials, which are an EPDM sheet-applied membrane, two kinds of PVC sheet applied membranes, a fluid-applied polyurethane membrane and a silicone-modified polyether sealant bead. We were tried to make recycled waterproofing materials through some techniques. The former four membranes could be reproduced to the same quality as the materials satisfying Japanese Industrial Standards. As for the last one, we couldn't find any recycling technique except usage as adding material at mixing. Finally, we pointed out the importance of development of the techniques for separating aged membranes from concrete substrate, and also extracting resin from fiber reinforcement type sheets.

Generally, it is important to minimize unfavorable effects of torsional response to seismic actions in designing building structures. On the other hand, however, this requirement often hinders free architectural planning. An application of hysteretic and viscous dampers in a middle-rise building with large eccentricity is introduced in this paper. Efficiency of the dampers in reducing horizontal and rotational displacements caused by intense seismic actions is verified with time-history response analysis.

Computational morphogenesis technique is one of the newly developed computational methods for structural design, which is based upon the structural optimization methods and has recently begun to be used for structural design process of the actual buildings. In this paper, one of the actual examples of their application is reported, where the extended ESO (Extended Evolutionary Structural Optimization) method is used for the wall design of an office building. It has been found that the computational morphogenesis scheme can be effectively used for examination of the structural form especially in the beginning of the design process and the organic form of the structure generated through the usage of the computational morphogenesis scheme has not only the structural rationality but also a fresh appearance not easily acquired through the usual designing process.

A combined foundation method consists of small size steel piles and compacted gravel on the top of those piles is proposed as foundation works for residential buildings. A series of field tests are conducted to clarify the structural behavior of such foundation system, and the spring constants used in design calculation are studied. Tested parameters are the diameter of steel pile and the thickness of compacted gravel. In general,, the ultimate bearing capacity of the specimen becomes large with the increase of the diameter and the thickness. As a result, well compacted gravel with the thickness more than 50 mm realize a rational structural design, reducing the stress concentration in footing beams, and at the same time, enhancing the bearing capacity of the foundation works.

Up to now, no systematic literature on the damping performance of space structures has been available. This paper outlines the damping performance required in current seismic design and the status of vibration measurement, and represents the results of analysis on collected vibration measurement data. The analysis revealed that the friction damping due to slippage between connection bolts and structural members was found to be the major cause of the damping of space structures. Furthermore, it was found that the design of space structures needs to take into consideration that the damping ratio is not proportional to the frequency.

In this paper, we discussed the repair and the effect of decompression filling of epoxy adhesive of GLT beam-to-column drift pin joint. We applied same cyclic loading schedule to the joint before and after repair. As a result, strength and the absorption energy was the same or getting better compared with before and after repair. And after all loading programs was over, we dismantled the repaired joint. Therefore we confirmed the adhesive was able surely to be filled by the decompression technique. After the repair of this kind of epoxy, strength of joint has the possibility to go up more than it is built because three (bonding the crack, gap filling and the gluing members) were included in the effect of the repair.

This is a technical report for the structural properties of capsule-shaped void slab, which has been developed and introduced to actual buildings in order to eliminate beams at slab ceiling. This void slab has two characteristics. One is high void ratio to provide one of the lightest void slab in Japan. Two is its isotropy nature which enables to design variously outlined slab. Both are verified by the isotopic round shape voids around which concrete is easily cast against their narrow gaps contributing its high void ratio.

Damage controlled building incorporating dampers has been popular in Japan, however, few numbers of low-rise buildings are applying this concept. One of the reason is such buildings have difficulty for incorporating brace or wall dampers. To solve this problem, authors have proposed elasto-plastic damper at beam ends, which can be replaced after large earthquake. In this paper, the varidity of this damper is velified using two practical building models, followed by the proposal for simplified response estimation method, which requires no time-history analysis.

The plastic deformation capacity of steel beams is regulated as restriction on the depth-thickness ratio by the Japanese building design codes. The capacity is, however, determined not only by the depth-thickness ratio but also by the collapse mode of the beams. Controlling the collapse mode improves the plastic deformation capacity of the beams. In this paper, difference in plastic deformation capacity and collapse mode is evaluated by the ratio of the shear strength to bending strength of beams and an example of rational design of steel beams is introduced.

Since the wind power generator system making use of wind flow around the building may be used effectively in an urban area, we developed such system that is assembled with a micro wind turbine of 500mm diameter and small generator. The basic performance of the element of the turbine was tested and installed at the field near a building for 13 months. The wind power generator system showed the following properties that could have high power coefficient. When the fixed directions of each micro wind turbine were optimized based on the predicted result of the wind environmental assessment at the installation site, it was confirmed that the amount of power generation for a micro wind turbine was 7% of the total wind energy on site through one year practical running.

Based on the measurement result of a building thermal mass storage system with air insufflations in use, a method to approximately calculate the charging/discharging rate of heat was worked out. Simulations with this method were carried out under various conditions of air insufflation, operation hour, etc., and have given approximate expressions, which can be applied to most cases to calculate the stored amount of heat. It has been found out that the discharging rate of heat at the corresponding time is almost the same, regardless of charging conditions, and it is utilized to generate a daily profile of heat load.

We held a workshop of Klimaatlas on 23th and 24th November 2003 in Sendai. This workshop was held for examinations of making process of the climate analysis map and the recommendation map based on climate analysis data at summer. We took up 3 areas, near the seashore, residential sections on hill and central district of Sendai city. Through three sub-committee meetings, the maps were made based on various data, for example climate analysis data (include the results of numerical analysis), land use maps, and city planning data and so on. After that, we discussed about what is urban environmental problems in Sendai. As the result, it is cleared that we must consider characteristics of regional climate when we design urban planning.

The performance of newly developed water retentive pavement was tested in field experiments. For the evaluation of water holding ability, on site estimation methods of evaporation efficiency was developed in this study. At first, convective mass transfer coefficient at experimental site was measured by evaporation rate from a filter paper test piece on the ground near pavement sample. Next, using analogy between mass transfer and heat transfer, sensitive heat flux at pavement surface was calculated using convective heat transfer coefficient. Finally, evaporation rate at pavement surface was estimated as a residual of surface heat budget.

In recent years, China has had significant development on construction sector. An enormous amount of the building, particularly residential building has been constructing. However, many of the buildings have poor insulation and poor thermal environment. Increasing of the air condition usage will cause large energy consumption and urban heat island phenomenon. In the face of these problems, China has revised the residential building energy code and standard for the energy efficiency design of building envelope and space heating for new construction and expansion of residential buildings. In this research, the authors have carried out the research to investigate the characteristics of building energy standards of the residential building in China, Efforts have also been made to promote a better understanding of the energy policy and relevant standard for architects and building designers to achieve optimal energy efficient building design, and also for assuming the building energy consumption, assessment of the thermal environment in China.

This study developed an environmental design tool by combining an outdoor thermal environment simulation with 3D-CAD system performed on personal computer. The outdoor thermal environment simulation applied in this development is able to predict surface temperature distribution of urban blocks taking the spatial form and materials into consideration. Pre- and Post-processing methods were developed considering actual design process. This development actualizes the input and output process using GUI function. The CAD models created by ordinary drawing process are automatically transformed into the mesh model for the calculation. Also the design parameters, inputted in the CAD model drawing process are converted to the parameters used in heat balance calculation. The output of surface temperature distribution is visually displayed onto CAD model.

New assessment system for buildings known as CASBEE (Comprehensive Assessment System for Building Environmental Efficiency) has been developed. In CASBEE, two environmental aspects i.e. environmental load (L) and quality of building performance (Q) are set as the major assessment targets. BEE (Building Environmental Efficiency) is defined as Q/L, following the concept of eco-efficiency. This assessment structure is the most unique point of CASBEE compared with existing assessment tools. With the increasing BEE value, total environmental performance of buildings is labeled as any of Class C (Poor), B-, B+, A, and S (Excellent). CASBEE is going to provide four tools according to the lifecycle of a building.

A calculation tool is developed to estimate reduction in CO_2 emission from Governmental facilities and schools constructed according to Aomori Prefectural Guideline on Environmentally friendly Architectural Design. This simplified LCA tool, that also calculates initial and lifecycle costs, is so easy to operate that user only select measures to reduce environmental loadings through planning process. CO_2 emission from governmental facilities by the year 2010 was predicted with combination of the environmental techniques used in new construction, existing buildings and renovation projects. The Aomori government increased its budget as additional cost to introduce these measures for new construction of governmental facilities

The Polymer Electrolyte Fuel Cell system is now under development for detached houses. Because the system is able to supply not only electricity but heat, it has high energy efficiency. The environmental load of the system can estimate by using the hourly schedule of electricity consumption, hot water supply and gas consumption. The model house of this study is a Japanese standard wooden house in Fukuoka. We compare the conventional system with the FC system from its consumption of energy and discharge of carbondioxide. In addition, the power generation capacity and the operating scheme of the FC have been changed to analyze their effect. As a result of this study, energy requirements of the FC system is lower than the conventional system, and carbon-dioxide emissions are also small.
