In this experiment, the strength development in structure specimens of high-strength concrete using the blast furnace slag fine aggregate was studied. As results, it is less than specimens of standard curing that the proportion of mixing the blast-furnace slag fine aggregate influences the deterioration of strength about structure specimens. In period of curing, the temperature of concrete using blast furnace slag fine aggregate is slightly higher than concrete using sand in structure specimens. Strength correction value (S value) of the concrete using the blast furnace slag fine aggregate is smaller than the concrete using river sand in structure specimens.

In this study, a new simple method was firstly developed for measuring the thermal conductivity of concrete. Then we measured the residual compressive strength and thermal conductivity of a series of specimens after heated at different high temperature levels, which were produced with different raw materials and had different strength grades, and examined the relationship between thermal conductivity and heating temperature. Furthermore, the relationship between residual compressive strength and thermal conductivity is quantitatively discussed and modeled. Based on this model, we proposed a method for estimating the compressive strength distribution in heated concrete member.

As the result of the research of the literatures on concrete strength correction value of CFT structure, we have found as follows,
1) The result of test calculation of strength correction value Sd shows that the appropriate value for the concrete lower than Fc60N/mm² should be 5N/mm².
2) The result of test calculation of strength correction value Sc amounts to 7 - 12N/mm² recommended by Association of New Urban Housing Technology (ANUHT). We have confirmed that the value of Sd, 1) above, is larger than the value of Dp, Diaphragm effect coefficient, proposed by ANUHT.

In case of use for recycled coarse aggregates produced from demolished concrete, a large volume of fine aggregate is generated. To use the fine aggregate effectively and safely, it is required to understand the leaching characteristics of Cr(VI) leached from the fine aggregate, and to execute a measurement to reduce Cr(VI) leached when the volume of Cr(VI) leached exceeds the limit of soil environmental standard.

Recently, the number of extensive repair work in high-rise building increases. Assessing the degradation state of sealant in high-rise building is usually performed by visual observation used by gondola that provides only a cursory evaluation of the product. In this report, we investigate to establish the method of evaluating the degradation state of sealant by gathering small samples. Concretely, we investigate whether assessing the degradation state of sealant is possible even by the chemical test besides the visual observation and the physical testing.

There are about 10 million existing non-conforming wooden houses today in Japan, and upgrading the seismic performance of such houses is essential for disaster mitigation. However, most of them remain untouched partially because the effect of upgrading is not quite clear for the owners. The owners might ask “is it necessary to upgrade to the level required by the current seismic code?” “what if the upgrading is carried out not now but a few years later?” In order to answer such questions, the authors developed a tool on a web to provide seismic risk information. The owners can compare the effect of several upgrading alternatives, and could make a reasonable decision based on their sense of values and their life stage.

To effectively control transient responses, we propose TMDs with initial displacement. The initial displacement can change the phases of beat envelope curves resulting from superposition of two vibration modes with closely spaced natural frequencies. In this paper, we describe the vibration test under impulse loading to verify the effect of the proposed system experimentally and that a model of TMD made on an experimental basis works validly. Firstly, we explain the effect of vibration control of the proposed method to the plate model on the analytical basis. Then, we explain experimental results and lastly compared experimental results and analytical results.

Although it is recognized that a tuned mass damper (TMD) is very effective in reducing wind-induced response of a structure, it is not in reducing earthquake-induced response. This is because a very large supplemental mass is required for seismic control of the structure. The authors have proposed a new seismic response control system, the tuned viscous mass damper (TVMD) that has an apparent mass amplifying mechanism to obtain a large supplemental mass effect enough to suppress earthquake-induced excitations. In this paper, the applicability and effectiveness of the TVMD to an inelastic MDOF system are illustrated by a design example.

A series of cyclic loading tests and unconfined compression tests were carried out for the foamed mixture cement soils with an air containing ratio of less than 50%. As the results, it was shown that the foamed mixture cement soil did not decrease its strength even after 80000-cyclics loading. However, the unconfined compressive strength decreases gradually and the secant modulus of elasticity decreases drastically with increasing number of dry-wet cycles. Therefore, it is important to take the decrease of secant modulus with the increase of dry-wet cycles into consideration in case of usage at the depth of the groundwater table.

We predicted and then measured the settlement behavior of a raft foundation for a 43-story R/C condominium in order to verify the accuracy of the prediction. The soil was regarded as elasticity in the analysis using the Young’s modulus evaluated from shear wave velocity strain-dependent and confined-pressure-one. The following conclusions were reached:
1) The measured maximum settlement of the foundation was 24mm, which was 80% of the prediction in disregard of the water pressure just below the foundation.
2) The accuracy of the settlement prediction improved when the confined pressure-dependent of the soil stiffness was considered in this case.
3) The prediction method is applicable to heavy buildings on raft foundations that have mean contact pressure of 0.8MN/m².

Two new low-cost shear walls have been developed, to effectively strengthen a conventional wooden structure without any change in the foundation of the house. The sheathed shear wall with a 330 mm height wooden beam does not require RC beam foundation. The brace shear wall has “all-threaded steel” bars and so-called “hole-down joint metal”. Furthermore, a 46-year old wooden house was retrofitted using the two newly developed walls as well as other conventional strengthening’s. It was confirmed that after strengthening, all indices are greater than 1.00 and the natural period becomes shorter.

In this paper we conducted shear-type tests with initial cracks on block-shear-specimen or not.
For block-shear-specimens without initial crack, the longer the shear length is, the smaller the shear strength. It is difficult to evaluate the real shear strength based on JIS methods. For some type specimens with initial cracks, we defined maximum load as crack starting criteria and calculated energy release rate in theory.
As a result, type 3 specimen named in this paper is useful for evaluate mode 2 fracture toughness.

In order to establish a method to evaluate the seismic performance of existing wooden houses by microtremor measurements, we studied the possibility of using natural frequency as an index.
We could obtain a higher correlation between the natural frequency of a house calculated from the stiffness of the walls and the weight of the house, and the natural frequency from microtremor of the house, by using the stiffness acquired without applying reduction factor with joints, foundation and deterioration. The correlation was also improved greatly by using the stiffness in the microdeformation instead of that which is currently used for seismic diagnosis.

We experimented on the shaking table of the 1/6 scale models of slip hysterisis characteristics that assumes the timber structure. And, we experimented the addition of the damper to those models. This report verified the influence that the slip characteristic, the modulus of eccentricity, the floor stiffness, and the oil damper exert on the seismic peak response displacement.
As a result, the seismic peak response displacement in the influence of the modulus of eccentricity and the floor stiffness is 3.0 times as large as that in the influence of the non horizontal twist behavior. Moreover, the oil damper had a large effect of the decrease.

Short-span beams that connect core walls in super high-rise apartment buildings are subjected to high stress and deformation during a great earthquake. An attempt is now being made to use strain-hardening cementitious composites (SHCC) with great shear strength and high ductility in short-span beams. Loading tests for SHCC beams have revealed the following points. 1) SHCC beams suffer flexural failure at a shear redundancy of 1.25 or higher. 2) Critical rotation angle of member R exceeds 1/20 rad and SHCC beams provide sufficient ductility at a shear redundancy of 1.35 or higher.

In this study, pullout loading test and simple beam test is conducted to investigate bond splitting behavior of SHCC (Strain-Hardening Cementitious Composites) members with small reinforcement spacing. As the results of the experiments, the brittle behavior due to bond splitting is restrained by the confinement of fibers. The experimental bond strength shows higher value than calculated strength by conventional formulas for concrete members. The bond splitting strength of SHCC can be evaluated by the thick cylinder model assuming that SHCC around the reinforcement is subjected to “plastic stage”.

The number of more than thirty-year old condominium is predicted to be increasing drastically. The problem is how the independent renovation of these condominiums in the urban area will be attained. The purpose of this paper is to evaluate the reconstruction-feasibility of old condominiums by reducing the rate which is calculated from “land price based on street value” and “construction cost”. By using the evaluation model based on the equivalent exchange, the characteristics of Bunkyo and Koto ward of Tokyo on the reconstruction-feasibility are clearly confirmed. The simulation has been conducted on cases of mixing “a self-pay burden for residents”, “alteration in the unit area”, and “the diminishing the ratio of the total floor area”. With time series analysis, the effects of reducing self-pay expense for each area and case have been confirmed.
