    In this paper, we examined the best curing condition to manufacture a ultra-high strength mortar of 300N/mm2 class. As a result of the study, the influence that the warm water curing had on the high intensity was the largest. The impact by the pressurizing curing was comparatively remarkable. The ultra-high strength mortar that exceeded 300N/mm2 was able to be made by combining the warm water curing, the heat curing, and the pressurizing curing.

    The concretes containing large quantity of fly ash with constant portland cement content were produced at the ready-mixed concrete plants, and placed into full scale formworks. Their fresh and hardened properties were measured and discussed.
    1.At various fly ash content per unit volume, for example 455kg/m3, the concretes which have various flowability, such as medium or high fluidity concrete, were produced easily. And they could be filled smoothly into narrow space of wall formworks with reinforcements.
    2.The fly ash concretes appeared higher compressive strength from the early age and carbonation resistance than those of the concrete without fly ash.

    Various kinds of sheets made of PVC are used as a finishing material for building. These used PVC sheets are dumped voluminously as mixture waste. So the development of recycling system of waste PVC sheets was studied in this paper. Fundamental physical property test such as tension, elasticity, etc. and durability tests were carried out on recycled PVC specimens. The influence of waste PVC compound mixing rate on the quality of recycled PVC sheet was confirmed through those tests. Consequently recycled PVC sheet is deemed applicable to use for the waterproofing sheets.

    Using one typical kind of free-access floor specimen, the behavior during seismic excitation by three-dimension input wave was compared with that by horizontal one-dimension input wave. As the conclusion, it was obtained that damage by real three-dimension seismic excitation could be estimated based on the result of the excitation test using one-dimension input wave, which was selected from two horizontal axes as the direction containing the maximum acceleration. The result of this study will be applied to establish the simple method to evaluate the seismic resistance of free-access floor, which will consist of one-dimension excitation test.

    The sliding bearings are used for lightweight structures instead of the laminated rubber bearings. In many studies, the frictional coefficients of sliding bearings are assumed as less than 0.1. However, even if frictional coefficient is about 0.2, it may be effective for a big earthquake (max. acceleration > 200cm/s2). In this study, the effectiveness of sliding bearings made of surface-treated steel plates is examined. The reduction effect of response is proved by shaking table test, and the frictional coefficients are identified analytically.

    A multi-belled cast-in-place concrete pile construction method has been developed in order to obtain a high level of bearing capacity with normal pile. The newly developed multi-belled pile has a shape of some bell enlargements at its axial part and consists of high strength materials such as high-strength concrete of Fc60N/mm2 at its maximum. The investigation of actual-size pile digging out after construction was carried out to measure the dimensions and concrete strength of the pile. The results indicated that this method controls high construction quality of the pile. And the case history applied to super-high-rise building foundation was also described.

To evaluate structural performance shear wall tests consisting of six type details with and without opening was carried out. Shaking tests were also conducted for two story house having insufficient structural performance and two story house with developed shear wall. As the result of tests, wall strength ration of over 7.0 point in seismic diagnosis for existing wood house was calculated from shear wall tests and significant difference between two houses with and without reinforcement was observed in shaking table test.

As a result, soft reclaimed soil under Hatto, one of the largest temple building in the site, was shown to be one of the dominant reason for the building damage. The Hatto building and its surrounding ground were investigated in detail by microtremor and seismic response observations. Dynamic characteristics of the buildings and ground were shown.

    New seismic suppression system has been developed. In this system, the structural elements absorbing seismic energy are provided completely apart from the parts supporting vertical load. Steel dampers and oil dampers are incorporated as the seismic response control devices. In case of earthquake, these energy dissipation devices act effectively and absorb seismic energy. As a result, high seismic performance can be obtained and a new architectural frame can be realized as well. This paper describes the outline of this new system and the application to an office building and this structural design.

    Thermal insulations of detached houses are much more important in the 21st century, in which the world focuses are paid on the global warming issues. Performances of thermal insulations are evaluated using the Q-value (heat loss coefficients) on desks. However actual performances of thermal insulations are not realized only by insulation thickness, but are also affected by the air tightness of the building envelopes and by the insulation methods. This paper describes a practical field measurement method of the Q-value, developed by the authors, and shows example data obtained in existent detached houses using the developed measurement method.
