High-fluidity concrete that has been developed recently seems to have several characteristics concerning the fluidity of raw materials. Therefore, data on pumpability of concrete need to be compiled and become useful statistics in this area of study. This report focuses on an experiment conducted on viscosity agent mixed concrete for determining the pumpability of it using portland blast-furnance slag cement. Here same types of raw materials are used where the water-cement ratio was made to vary in two different cases, high-fluidity concrete and the other normal concrete. Here concrete mixer truck was employed while the pumping distance was set at 25m and 100m. The analysis was made on factors like slump, air, pressure in pipe and pressure loss.

In Japan, plywood panels have been mainly made of a lauan and almost all of them have been used for forms of concrete. But technological inovation of plants of a plywood has leaded the situation of overabandance. As the results, the plywood market is so confusion, and the price of plywood has sometimes been hovered around. So many plywood manufacturers begin to process a plywood to be plaster base. The author has tried to apply plywood to any other building materials. In this report, author discusses about the process of plywood and the costs of goods and the effects of stabilization of price of plywood. It is proved that the profit of the curtain wall is better than any other wooden plaster base.

Preceding materials for concrete pumping constructions are indispensable but generally abolished after the pumping. Recent environmental preservation and resource saving tendency require preceding materials to cover the necessary pumping distance with a minimum amount and to have no harmful influences on the resulting concrete quality when mixed with the pumping concrete. We have executed an experiment of concrete placing in model columns using a preceding mortar which was composed of premixed cement, admixtures and mechanically stabilized fine aggregates, and confirmed that the preceding material mixed with the main concrete had no harmful effects upon the final concrete quality.

The present investigation was carried out to study the adhesion of bonding cement mortar to deforming super workable concrete substrate. The specimens were tiled using the prefabrication method and the manual method. The compressive load was applied on the specimens, and the critical concrete strain before tile separation was measured. As a result, the critical concrete strain of super workable concrete was larger than that of ordinary concrete. And in case of manual method, the critical concrete strain of the specimen tiled on uneven concrete surface was larger than that of the specimen tiled on flat concrete surface.

It is necessary to evaluate bending deformation of laminated rubber bearing and installation elements when the installation elements cannot be assumed to be rigid. We obtained following test results. (1) Bending stiffness have non-linearity and dependence on vertical load. (2) Additional shear deformation is induced by internal force caused by vertical load and inclination of rubber sheets. We formulated horizontal stiffness of laminated rubber bearing assuming that only compression area can bear bending moment. The formula canevaluate additional shear deformation and bending stiffness. We proposed a practicable analytical method which consider flexibility of installation elements and P-δ effect.

Electric Power Development Co.Ltd. is now building coal-fired thermal power plants at Tachibana-cho. Anan-shi in Tokushima prefecture. In the project, they planned to build eight (8) large-sized silos for coals whose capacity are 70,000 tons weight. When we designed coal-silos for earthquake loads, we should consider interaction between coals and structure. Damping forces of coals become large in inelastic region of their strain and coal absorbs a lot of seismic energy. We confirmed structural safety of silos to big ground motions by the design method considering inelastic behavior of coals.

A hybrid mass damper system with convertible active and passive modes using a hydraulic actuator has been installed to an actual slender tall building with an aspect ratio of eight constructed in Chiba prefecture. Force vibration tests and observation of behaviors against moderate wind excitations were carried out to investigate the response control performance of the mass damper system. From the analysis, it was confirmed that on the active mode due to the vibration tests, the damping factors in the 1st mode were about 8%〜11%, the satisfactory vibration control effect was obtained, and no spillover in the 2nd mode occurred. The response values of the peak and the R.M.S. accelerations under the active mode due to the seasonal wind excitation were reduced to 1/ 4.5〜1/2.0(average 1/3) in comparison with the responses in non-controlled system. Through the results obtained by these investigations, it was concluded that the mass damper system was quite effective for the response control of the slender tall building to wind loads.

A new formula to estimate sliding displacements of furniture during earthquakes is proposed. This formula indicates that sliding displacements are proportional to the square of input velocity and inversely proportional to friction coefficients. It is ascertained by analyses using a simple model and various input waves that the formula indicates almost maximum sliding displacement of furniture for an input velocity. By using this formula, we evaluated sliding displacements of furniture under various conditions. As the results, it becomes clear that sliding displacements are largely influenced by friction coefficients, soil conditions and floors where furniture is installed.

An investigation of the damage to the piles of the apartment building which were suffered from the 1995 Hyogoken-Nanbu earthquake was performed. And by using a part of the piles with little damage which were extracted from the ground, loading test was conducted to clarify the failure mechanism and the lateral force acted on the piles. From the results of the investigation and loading test, the following conclusion were obtained. (1) The piles failed by shear force and then crushed by axial force. (2) The failure pattern of the piles observed in the loading test was the same as that observed in the field. (3) The shear force to cause the failure of pile during the earthquake was estimated to be 360kN.

During the 1995 Hyogoken-Nanbu earthquake numerous cases were observed where buildings were structurally or functionally damaged due to the suffering of the foundations. The seismic safety of a building should be comprehensively judged considering not only the superstructure but also the foundation. There is an authorized standard for seismic capacity evaluation of superstructures, whereas not for the foundations. In the paper we propose a method of seismic capacity evaluation of existing building foundations considering their ultimate strength, failure modes and ductility.

Performance-based fire safety design was applied to a high-rise office building. Under each objective, required functins are specified associated with quantitative performance scale. The framework allows any combination of fire safety provisions as long as the required performance is achieved. Compared with prescriptive design method, the performance-based design method provides with open type office area, spatial efficiency (rentable ratio) and daily functionality. In case study, safety checking was made for evacuation safety and structural fire resistance. For the whole process of safety checking, simple hand-calculable formulae were adopted to give a quick estimate of the safety level. Through this case study, it was demonstrated that the performance design is practically feasible.

A family is now a unit with an individual person as a basic component. Social services and networks gradually take over some of the roles of family members. The traditional formula of nLDK type of dwelling that limited the relation among 'society, family and individual' no longer applies. Instead variety of housing styles emerge as individuals begin to choose their own styles of relating with society and their families.

Through the study of campus planning, planning issue are changing recently. The reason why change is that the request of society, re-evaluation of relation to campus and surrounding area, and concept of making use of campus to form amenity urban space.

Purpose of this paper is to clarify the present condition and the direction of improvement at the historical city core in local small cities. 262 autonomies in Japan defined as those cities. Now, they have the problem that commercial activity and the population aredeclining in those area. And most autonomy's staff have the direction of improvement that they havedeveloping the commercial district, but 8% autonomy's staff have the differentdirection.They have the view to decrease the commercial district and to change theremainders for the residential district. And these autonomy have the same distinction that city core's position is lower and they don't have much foundation of past city planning.

Demand estimation of medical, health care and social welfare facilities for the aged in 2000 was carried out through the Cohort method in Muroran, Noboribetsu and Date. Those were compared with demand of facilities in "Health Care and Welfare Plan for the Aged" of each city. Some kinds of facilities in Muroran and Noboribetsu aren't enough because trend type of estimation wasn't suitable. But those facilities in Date are enough because of its ahead of the aged policy "Prime Healthy Town Plan" and its implementation and its stabler change of population than Muroran and Noboribetsu.

Because of long and widespread depression, municipal government have faced the cut-down of the cost of public buildings: construction cost, maintenance fee, heat and light expense. Setagaya-ku set up a deliberative body consisting of its directors of related departments and researchers, and published a report titled "A guideline for Total Cost-control of Public Buildings" in December 1997. This report proposed that establishing a new specific cost-control institutional section and utilizing existing facilities are essential to control the cost of public buildings. This paper explains about the grounds and material for the report.

This report presents the kiwari-systems in the architectural manual books that were written before the early part of the 17th century. Those old records were handed down to the recent years by the KOBAYASHIS who were inaugurated as the DAIKU-TORYO that was the post for the authorized carpenters in SHONAI-HAN. Their descriptions are about the architectural techniques to all kinds of architectures and the architectural formalities, so they are important to study Japanese Middle Ages architectures. Among those architectural techniques, this report presents especially the kiwari-systems of the residence.

North America has seen real growth in the activity and value placed on the archiving of architectural materials. But whereas Japan has maintained a strong tradition of preserving its cultural legacies, architecture and its documents have not been among them. There is not a single architectural archive in Japan. In June 1996,1 began working as an intern at Columbia University's architectural drawings collection in the Avery Architectural and Fine Arts Library. I also had the opportunity to travel through out North America to visit and investigate architectural archives. My specific goal has been to gather information and strategies that will motivate and guide the establishment of architectural archives in Japan. Inthis article, I introduce the roles and activities of the architectural archives inthe US and Canada.

Version control of a lot of documents without any tools would be difficult for project participants. The version control system we developed in this research would help them manage versions of drawings. We integrated a relational database system, CAD software and Internet services. The system will give users some information about history of drawings such as modification, printout and approval, and it will also notify users when external reference drawings are modified or a violation occurs. Systems like this can be a useful tool to arrange drawings made by some participants.

GA (genetic algorithm) is well known by the comparatively good ability to get solutions of various combination problems in a short time. Because optimal solution may not necessarily be obtained, expanded GA that has some operations in addition to fundamental GA operation is employed in this paper. This paper proposes a practical optimization method of structural planning of a lattice dome by GA. Four evaluation functions, i.e., cost of dome, deformation, buckling load of whole dome and that of structural members are employed in GA operation. Consequently, it is proved that approximate optimal solutions can be efficiently obtained in comparison with the calculation results of all combinations of given parameters.

Although a numerical calculation program often has a complicated datastructure such as a multidimensional array, you are forced to fit your data intoflat files by reason of OS restriction. If you can reuse old data to generate new one, the efficiency of data generationbecomes better. To meet the demand, you may select a database system as adata storage for your program. The authors developed two applications for a calculus of finite differencesprogram, one uses a relational database management system and the other usesan object database management system. The paper reports a feasibility studyof using database systems as a data storage for a numerical calculationprogram.

Some basic issues associated with development of seismic dampers (Rotary Damping series) applied to ball screw for seismic performance enhancement are studies in this paper. RD series are consists of ball screw section and damper section. RD series has 2 types of damper section, RD-tube has a tube type of damper section, RD-disk has a disk type of damper section. RD series have more efficient viscous damping force applied to amplification of ball screw.
