This study looks at the effect of the ratio between mortar and coase aggregate on the quality of hardened high-fluidity concrete, by varying the unit volume of the latter. The process includes a variation in composition of mortar and coase aggregate during construction, thereby keeping the amount of chemical admixture and fine aggregate constant with respect to the cement volume. Then the properties of hardened concrete were examined, which revealed that if the ratio between mortar and coase aggregate subatantially deviated from the designed mix-propotions, the quality criteia for the high-fluidity concrete as specified in JASS 5 was not met, and therefore it is strongly recommended to opt for a careful construction process that does not vary the components of concrete as above.

This paper deals with filling capabilities of concretes injected into CFT columns. Bibliographies related to current CFT injection technologies were widely reviewed and the filling capability was analyzed. Based on this background, normal and high-fluidity concretes were injected into two types of steel tubular columns, and effects of the type of concrete on the injection height in the steel columns were studied. The filling capability of concretes became more satisfactory when the high-fluidity concrete was used at a low water-cement ratio, and greatly influenced by the opening area of diaphragm with respect to the cross section of the steel columns.

The seismic isolation retrofit of the main building of the National Museum of Western Art required excavating the foundation ground under the existent building and installing isolation devices beneath the existing footings. Before the installation of isolation devices, it was necessary to construct piles beneath the existing footings in order to support the weight of the building temporarily during excavation process. The piles were made of steel pipe segments, and were driven by oil jacks utilizing the weight of the building for reaction force. During the retrofitting process, the subsidence of the building supported by the piles were monitored and controlled to avoid causing damage to the superstructure.

The creep characteristics of laminated rubber bearings in actual base-isolated building are estimated by monthly measurements of the temperature and deformation of rubber bearings using multi-micrometer since 1986. Furthermore, hourly high-precision automatic measurements of deformation and temperature have been started since 1993 using newly-developed laserdisplacement sensors and thermocouple. The spring constant variations of laminated rubber bearings for eleven years are estimated growing stiff more than initial conditions by static tests of aging small laminated natural rubber bearings for maintenace and actual rubber bearings in base-isolated building.

This paper reports on a project wherein 4 storied basement was demolished and 5 storied basement was reconstructed. The existing basement had been constructed fully on the site. In order to shorten the construction term and reduce the construction cost, the new basement was designed after sufficient research on the demolishing and retaining procedures. After rock auger work on the existing concrete, soil mixing retaining walls were constructed. Concentrically assembled temporary struts were adopted to simplify demolishing work by hydraulic hammer. It took about 19 months from demolishing the 4 storied basement to reconstructing the 5 storied basement.

To improve the performance of a bored steel H pile installed in a prebored hole, a grouted base is made around the base of the pile. The structural capacity of the pile with a grouted base was studied by two series of model loading tests. Failure mechanism was observed, which depended upon the geometry of the grouted base. The failure occurs in which the grouted base is thin, less than twice the pile diameter. Structural capacity increases with increasing the thickness of grouted base. Field tests were caried out, boring test, excavated measurement and loading tests. The effectiveness of the method and large ultimate bearing capacity were proved by the tests.

When we design a building on slope ground by using pile foundations, we often face to the difficulty how measure the lateral resistance of the pile foundations. However, there is no systematized database to help structural designers formulate such measures. Therefore, the Architectural Institute of Japan set up a working group to collect and analyze data from existing literature and summarize the latest technical information. This paper (part 2) reports on the results of analysis conducted by the working group and makes a proposal relating to the evaluation method of lateral resistance of pile foundations driven in and on slopes.

This design shows an application of a damage-controlled structure to a building having a diagonal lattice tube frame. The damage tolerant structure is a parallel combination of the primary structure and seismic dampers. The center portion of the diagonal lattice tube frame is made up of axial hysteretic dampers. The rigidity of the entire structure and the energy-absorption initiation level are controlled by varying cross-sectional areas of the diagonal columns and seismic dampers. By thus we have decreased the seismic responsiveness the conventionally elastically designed, diagonal lattice tube framed structure.

Taking into account the earthquake-resistant design standards in effect when the building was designed, new earthquake-resistant design criteria were established for the retrofit, to check the earthquake-resistant safety of the retrofit design. Structural and functional considerations led to a choice of laminated rubber for the isolator material. The results of vibration analysis using a mass system model demonstrated that the earthquake motion input into the building would be reduced substantially by the retrofitwork. It was also shown that the work would substantially meet the earthquake-resistant design criteria. Three-dimensional vibration analysis was also carried out using a solid frame model to calculate the margin of safety of each structural member would be earthquake-resistant.

Damping materials were applied to the floor of a four-story platform frame house in order to decrease heavy floor impact sound levels. Two types of viscoelastic layers were attached to the floor ; that is, two kinds of non-constrained viscoelastic layers and a constrained viscoelastic layer. Applying non-constrained viscoelastic layers to the floor resulted in the reduction of not only vibratory velocity levels of the floor and ceiling, but also heavy floor impact sound levels. The constrained viscoelastic layer had little acoustic effect. The increase of the stiffmess and damping of the floor may simultaneously affect these results. Thus further investigation is needed to clarify the mechanism of decreasing heavy floor impact sound levels by the use of damping materials.

In order to reduce the load to the earth environment, it is necessary to utilize natural energy. In this study, from this point of view, it has been investigated the utility of a fresh air load reduction system by using underground double floor space for air-conditioning in buildings experimentally and numerically. It concludes that the annual amount of energy saving by using this system is more than the energy loss caused by introducing it. Additionally, the computational results with the simple heat diffusion equation agree with the measurements. Therefore, it is clear that this system is very useful and the proposed model can use for the thermal design of it.

At construction sites, safety signs are very important things to keep workers' safety. However, they have some problems, that is, 1) some materials and tools are necessary to set up or move them, for example, wire and pincers, 2) they cannot be stuck on finished surfaces because they may be worn off. To solve these problems, the new 'STICKER SIGN' was developed. It has adhesive on the reverse side like a seal to be stuck on walls without any tools even if they are finished. Forty sites were observed to find the problems, and forty-four signs were evaluated by one hundred and fifty workers to find the adequate design.

The house construction companies want some rationalized construction methods. Some companies use a system of pre-cut or a system of panelized outside wall, and some use both. But these systems are not pupular in Hokkaido. And also we have to pay attention to the airtightness and the insulation. The purpose of this paper is to analyze what the construction, companies want to do for their rationalization to build wooden houses. In addition, I analyzed the airtightness in two building constructions.

This research is a step to make clear what are the standard details of nonwood constructions in Japan. A questionnaire survey about the own standard details books was made to selected architectural design organizations, and the present condition was made clear. The result says that there are some parts of a building which are likely to be standardized in drawings, but many of the details concerning to the building equipment are differently treated by each organization. And the computerization of the architectural drawings is changing gradually the state of the standard drawings.

This paper presents a study on selecting the optimum construction method for building projects with deep and large-scale underground work. Here illustrated (H building project) : an approach to be used in the preliminary phase of structural design and construction planning. Highlighting the underground work, statistical discriminate analysis proposed previously by the authors has been carried out. Adopting this analysis, the comparison study for both cost and construction program have been made in regard to three construction methods, that is, (1) Top-down construction procedure ("SAKAUCHI METHOD") (2) 1st floor slab concreting in advance plus combined H-section strut method ("IKKAI-YUKA SENNKOU SHUUCHUU KIRIBARI METHOD") (3) Conventional concreting procedure ("JUNUCHI SHUUCHUU KIRIBARI METHOD") To the final solution, a brief description of the SMW design and rationalization/labor-minimization by Top-down construction procedure ("SAKAUCHI METHOD") is given.

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 IKKENYASHIRO that is a kind of main sanctuary of shinto shrines.

In the urban seismic disaster mitigation or the aseismic design of building, it is essential to evaluate seismic ground motion properly. The geographical information system QuSE (Quickly Seismic Evaluation system) is newly developed here. QuSE has three main funtions which are the evaluation of seismic ground motion for virtual fault, the identification of active faults which affect any specific site, and the evaluation of seismic risk for arbitrary return period at any specific site. In order to evaluate the seismic ground motion properly, QuSE combines seismic related data, soil data and the various empirical formulas on Giographical Information System (GIS).
