In this paper, a method for predicting Young's modulus of cementitious composites produced by extrusion moulding is proposed. The applicability of the method was examined by three series of experiments. After the Young's modulus of matrices of composites are predicted, Young's modulus of composites are predicted by Hashin-Hansen equation, which is formed on the basis of Self-Consistent Approximation (S. C. A model) for finding composites mechanism on elastic modulus. Furthermore, it is clarified in case of extrusion moulding that Young's modulus of matrices are deeply influenced by visco additives and fiber additives as well as cement water ratio and degree of hydration. As the result of this experiment, predicted values are nearly equal to tested ones. Therefore, it is possible to predict Young's modulus of cementitious materials produced by extrusion moulding.

Inspection was made to examine properties of mortars ( 1: 1 - 1 : 5) randomly sampled from 10 ready-mixed concrete plants in the Kanto area. As fresh and hardened properties of the mortar, slump, slump flow, mortar flow, air content, bleeding rate, compressive strength, static modulus of elasticity and length change were studied. It was found that the properties of the mortar showed considerable scatter by plants though the designed mixture proportions were the same.

Large-scale outdoor monuments were made with exposed white concrete. A major hollow cone monument was designed as 7m heights, 7m base diameters and 24m^3 concrete volumes. To prevent air voids of the surface of the cone and concrete pouring joints, the cone form was set upside-down (V shape) and self-compactable concrete was poured continuously. After concrete hardened, the cone, with steel form work and steel supporting frame (total 120ton weights) was reversed into right posture, by overhead cranes putted on a temporary steel frame with computer control. The sculptor was satisfied with the results of these concrete works.

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, it was necessary to construct piles beneath the existing footings. Before the installation of isolation devices, construct piles beneath the existing footings in order to support the weigth 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 retro-fitting process, the subsidence of the building supported by the piles were monitored and controlled to avoid causing damage to the superstructure. The objective of this study is to investigate the axial stiffness and the yield strength of the piles during jacking. The axial stiffness is possible to underpin the existing building.

What asked for durability test methods for roof membrane systems is durability of their performance, not durability of the individual materials that compose the systems. However, the most tests that have been adopted as durability tests only focus on roofing material itself. Therefore it has been difficult to estimate durability of roof membrane systems by the present test methods. In this study, new test methods to make clear performances of roof membrane systems were proposed from the idea of combining the performance tests for them described in JASS 8 with degradation conditions. The items for degradation are heat, ultraviolet irradiation, ozone and moisture. The durability of the four kinds of commercial roof membrane systems was experimentally estimated using the proposed test methods.

With the construction and expansion of coal-fired power plants, Japan's total amount of coal ash will sharply increase to approximately 10 million tons at the end of fiscal 2010. In this research, we developed a new type of plantable porous concrete that incorporates the coal ash (clinker ash and fly ash) that is created a by-product of coal-fired power plant operation. The characteristics of coal ash make it suitable for use in plantable porous concrete, and we were moreover able to develop a mixture that ensures a high coal-ash utilization factor.

In incineration plants, RC stacks took the place of steel-supported stacks in '70s with the view of improving design appearance. A number of stacks having various shapes other than circle (square, triangle, and so on) have been constructed for the same reason. In order to investigate wind response characteristics of RC stacks having typical shapes, a series of wind tunnel tests were carried out. For the practical design, coefficients of wind force were evaluated based on the test results and in accordance with the method specified in "Recommendations for Loads on Buildings" of AIJ.

The objective of this paper is to evaluate fragility curve and repair cost in terms of each structural damage level based on the damaged database of 1995 Hyogoken Nanbu Earthquake. The seismic risk of a mid-to-high-rise building in Kobe is calculated through the analytical results. As a result, the following are verified : 1. The expectation of repair cost per square meter is about 29,000yen for minor damage, about 60,000yen for moderate damage, and about 64,000yen for major damage. 2. The seismic risk of a mid-to-high-rise building in Kobe, that is normalized by initial construction cost, is about 3.2 percent on condition that design lifetime is assumed to be 50 years.

The dynamic characteristics of a nine-story SRC building were investigated using incident waves generated from impactor machine. It is shown that this device can be right tool to investigate the vibration characteristics of the actual building up to relatively high frequencies range. Horizontal motions as well as rocking and torsional motions were investigated. The pulse like generated wave makes it possible to observe later arrival torsional response, which cannot be obtained in microtremor and vibration test using vibrator. To clarify the modal variations, mode decomposition analysis has been done.

In case of base-isolated houses, it is necessary to consider an isolation device with a triggering system to prevent isolators from moving against strong wind. The triggering system which enables smooth transition from a locked isolation system to an unlocked one, should be provided. Three-dimensional shaking table tests were conducted to verify the behaviour of lead-bar triggering system under earthquake loading. The triggering system broke down at the same shear force ratio as that designed. And the transition from the locked isolation system to the unlocked one was smoothly performed.

This paper deals with an application of hybrid mass damper (HMD) using linear motor to an actual tall building which has a height of 101m. By using the linear motor as an actuator, the HMD has a simple structure, little noise of working and an easy maintenance as compared with those using normal AC servomotor, because the HMD has no mechanical part to translate form torque to linear force. Its controllers, for the 1st and 2nd modes of X translation and 1st mode of torsion of the objective building, are designed by H^∞ control theory for absolute acceleration feedback control. The control system becomes also more simply than those of current HMDs which use state feedback control by optimal regulator, because the feedback signals are only two absolute accelerations of the top floor. The performance of the HMD is confirmed through excitation tests of the building and simulations against winds.

This paper presents parametric studies to obtain inelastic dynamic response characteristics of torsionally unbalanced single-story models. The following four models are analyzed ; 1) models with unbalanced mass, 2) models with unbalanced shear-strength, 3) models with unbalanced stiffness and 4) models with unbalanced shear-strength and stiffness. Major findings are as follows : (1) the total energy input is constant ; and (2) the damage concentration can be estimated by the first eigen mode and by the deviation of the yield shear force from the optimum one.

This paper describes the design of a high-rise building of 135m height with base isolation system using elastic sliding bearings and rubber bearings, dealing with the outline of structural design and the results of experiment of large-sized rubber bearings used in design. A dynamic response analysis confirmed the seismic performance to be excellent. Furthermore, from the tests on rubber bearings, their tensile property was grasped, and an inelastic model of their vertical stiffness was made. The response analysis using this inelastic model allowed the tensile forces at each rubber bearing to be estimated by the linear addition of the variable axial forces due to horizontal and vertical excitations.

Recently, the prediction of wind environment around a building using Computational Fluid Dynamics (CFD) technique comes to be carried out at the practical design stage. However, there have been very few studies, which examined the accuracy of CFD prediction of flow around a high-rise building including the velocity distribution at pedestrian level. The working group for CFD prediction of wind environment around building, which consists of researchers from several universities and private companies, was organized in Air Environment Sub-committee considering such a background. At the first stage of the project, the working group planned to carry out the cross comparison of CFD results of flow around a high rise building by various numerical methods, in order to clarify the major factors which affect prediction accuracy. This paper presents the results of this comparison.

We have established the system evaluation method in order to estimate the energy saving effect of the cold air distribution system. By this method, we calculated the systems' annual electric consumption. According to the AHU (s) location-one on the basement floor for whole building or one for each floor, distribution air temperature -16, 10 or 6℃, and chilled water supply method from the ice storage tank (s) -directly or indirectly with a heat exchanger. In case of small stories buildings, annual electric consumption for the central AHU system with cold air distribution is the lowest. In case of large stories buildings, in which each AHU is located on each floor, annual electric consumption for cold air distribution system of 10℃ is the lowest. As the cold air distrbution systems of 6℃ need more volume of chilled water, they spend more electricity than the normal air supplying system of 16℃.
