Assessment of strength in structure of high-strength, moderate-heat cement concrete was studied using an imitated adiabatic curing specimen. Strengths of the high-strength moderate-heat cement concrete placed in a full-scale model column specimen and that of the imitated adiabatic curing specimen subjected to the same temperature history as that of the full-scale model column specimen were compared. It may be possible that the testing of compressive strength of the imitated adiabtic curing specimen can determine the strength correction value S without testing the strength of concrete in structure.

One of the major concerns of High-strength concrete is its fire resistance. In some of our earlier high-rise RC projects, the most straight-forward measurewas taken to avoid the fire concerns : to provide additional finishing with normal-strength mortar layers all over the column surface. On the other hand, it has been known that the inclusion of polypropylene fibers improves the fire resistance of high-strength concrete by creating a pore structure that enables steam to dissipate. In this report, workability, compressive strength, durability, and fire resistance of the fiber concrete are summarized, and the application of such a concrete to an actual building construction is introduced.

RCFT columns (Reinforced Concrete Columns Formed in Steel Tubes) were used for the first time as the core columns of a 30 story high-rise hotel building. RCFT columns are high strength concrete columns contained in a thin-walled steel tube. The concrete is reinforced by high strength steel bars as the main reinforcement and deformed PC steel bars as shear reinforcement. This type of columns show excellent structural performance and fire resistance. Several factors need to be considered in the erection of such columns. These include, assembling and anchoring of the steel reinforcement within the tube, joining of reinforcement, erection of the steel frames, method of filling the steel tube with 80N/mm^2 high strength concrete and its quality control. These problems were investigated and solved through model tests and during the actual erection.

An approximate analytical solution on wind resistance performance forst anding seam roof construction, which is made of 0.6mm thick fluorine contained resin plate, is developed by using the method of applying a catenary on the curved line representing floating up height of roof construction due to wind pressure. From comparison between the test result of wind resistance and that of finite element method for verification on the above solution, it is confirmed that the solution can provide estimated values on the displacement of roofing materials due to wind pressure with high accuracy. The value from the solution sufficiently coincides with the value tested particularly within the range of wind pressure from 2,000N/m^2 to 5,000N/m^2. Therefore, it has been confirmed that this method is effective for the analytical solution for wind resistance of standing seam roof of 0.6mm thick fluorine contained resin plate.

New method of evaluating the compressive strength of high-strength concrete in structures using BOSS, Broken off Specimens by Splitting Method, was developed. Applicability of BOSS specimen was examined by comparing the compressive strength of specimens taken from a model structure by coring and by BOSS. Effects of water-cement ratio and the sampling height on compressive strength were studied with the variance analysis. It was confirmed that high correlation was found between compressive strengths of BOSS and those of core. Therefore the BOSS strength may be applicable to the prediction of compressive strength of concrete in structures represented by the core strength making use of the proposed formula.

This report presents a new hysteresis model of laminated rubber bearings for base isolated structures. Conventional models presented by manufacturers are not verified their propriety on estimating superstructures. Essential components of the new model are classified as follows. Non-linearity of second tangent stiffness is also highly significant as dependency of skeleton curve on strain. Unloading curve shape and variance of yielding load are significant. Hysteresis characteristics of lead-plugged rubber bearings (LRB) and highdamping rubber bearings (HDR) are idealized through assembling regression formulas. The new model is superior in expression of both variances caused by conditions of bearings and unloading curve shape.

The authors proposed the relationships between the coefficient of lateral subgrade reaction or the ultimate lateral resistance and the effective stresses based on the results of the lateral laod tests on model piles in sand. For a pile foundation in layers with various ideal effective stresses caused by an earthquake, its lateral behaviors were calculated by the proposed theory in which the above relationships were considered. Furthermore, the piles really damaged by the Hyogoken-Nambu earthquake were also calculated. It is found out from these results that the proposed theory is well able to predict the damages in the piles.

In 1998 Takiguchi et al. reported the interesting test results of the R/C columns. They gave large deformation to the columns until the columns lay down on the basement. We evaluated the test results and proposed the force-deformation relation model presenting stiffness degrading and bearing force degrading, for ductile R/C columns based on the test results. And we discussed the behavior of basic building models in large deformation under severe earthquake, by using extended distinct element method with the proposed model.

2001.3.24 Geiyo earthquake hit at Chugoku district, fortunately the extensive damage and economic losses did not occur though horizontal accelerations of 1g or greater were recorded at some sites. Concerning reinforced concrete buildings, a couple of low rise buildings were damaged. Two school buildings located at the same site in Hiroshima Prefecture, approximately 26km north of the epicenter, were damaged. One of them was severely damaged and another was moderately damaged while they had almost same structural systems. Objective of this study is to clarify the seismic performance of the existing RC buildings as those damaged buildings. Observed damage levels were compared with results of seismic evaluation method and nonlinear static analysis taking account of concrete strength. It was pointed that the obtained concrete strength which were nearly half of the design concrete strength aggravated damages of the buildings.

Low cycle fatigue tests and dynamic loading tests using several seismic response wave were carried out for the un-bonded brace damper that consists channel steel restraining its buckling. The result indicated that low cycle fatigue characteristics of this damper can be evaluated by Manson-Coffin equation and cumulative fatigue damage level that is evaluated by design curve proposed in the tests with Miner's rule was almost 1. As a result proposed design fatigue curve and evaluation method based on low cycle fatigue characteristics are considered reasonable for the damage level evaluation in seismic response.

Along with the revision of the Building Standard Law, the limit strength calculation was introduced as a new method of verifying the safety of structures against earthquakes. In this paper, evaluation method for earthquake response of buildings with hysteretic damper using the response spectrum method by equivalent single-degree-of-freedom model based on limit strength calculation was examined. As a result, in case that the equivalent viscous damping is appropriately evaluated, the maximum displacement response can be predicted by the response spectrum method using proposed evaluation method of equivalent viscous damping.

Concrete filled steel tubular (CFT) columns have become popular as structural member used for buildings, moreover, a large number of beam-column specimens have been tested. CFT structures are designed by either of the two standards, now. The superposed strength method is basically adopted for the design formulas in both of these standards, only considering the equilibrium of force. However, the lateral force-thrust-rotation angle relationships are not clear. Therefore, in this study, the structural performance of CFT columns have been examined based on the review of existing studies. As a result, the yield strength, the ultimate strength and the lateral force-thrust-rotation angle relationships of the CFT beam-columns have been clarified based on the existing studies.

In cold region, it is considered that dynamic performance of base-isolated buildings is significantly affected by thermal dependence of restoring force characteristics of isolating devices. However, there is not enough of basic data concerned with the thermal condition for designing base-isolated buildings. In this study, thermal environment of isolating devices is investigated by thermal observation in two base-isolated buildings. For improving thermal environment of isolating devices, results of observation suggest that it is effective to enclose them by thermally insulating materials. It is also suggested that the temperature of isolating devices is mainly affected not by outer thermal environment but by the temperature of upper and lower-side structure.

In order to improve the floor impact sound level of the standard rectangular void slab which is 5〜10dB higher at 1kHz band compared to that of ordinary RC slabs, we made several series of experiments. By experimenting light floor impact sound and impedance on the various types of void slab samples, we found that the ones with upper and lower shells fixed tightly were the best against the light floor impact sound and that considerable improvement on the rise of sound pressure at 1kHz. Then, we examined the effect on one of them by measuring the sound transmission loss, and as a result, this improved void slab got better result than 200mmRC slab.

Indoor air pollution by chemical substances from construction materials has caused health hazard. Bake-out is one of indoor air pollution measures. However, there is a case which bake-out is not effective on reduction of chemical substances emission from construction materials. The aim of this study is to clarify an effective range of chemical concentration in indoor air for bake-out. We experimented with actual residences. On the actual residences, in case of over 1700μg/m^3 TVOC concentration, it was reduced about 30% by bake-out. On the other hand, in case of under 80μg/m^3, it was reduced about 10%. Moreover, HCHO concentration was reduced 20% even under 30ppb.

The field observation shows that the leaf surface of the vegetation top iscooled to the lowest temperature in the vegetation by the sky radiation, while the air temperature inside the vegetation stays warmer during the clear night. The leaf surface of the vegetation top is refrigerated by the sky radiation, then the air next to the vegetation top is got cooled by the sensible heat exchange from the air to the leaf surfaces. Because of the observation errors on the leaf surface temperature, the calculated results have not completely agreed with the field experiments. The calculation results shows that the atmospheric air is easily got cooled if the leaf area index is large in the tall tree crowns.

In this paper, the effects of wind flow from rivers on outdoor thermal environment in the site for apartment houses, which locates near rivers, were investigated. First, a CFD analysis was carried out for day-time in summer. Then, a CFD analysis for the situation where one river was covered by asphalt was also carried out. Furthermore, suitable building layout for leading the wind from rivers to the targeted site was discussed based on CFD results. With the modified layout, the results showed significant improvement of outdoor thermal environment. It is shown that CFD can be a very useful tool for outdoor environment design.

This study is positioned as one of the life style researches of northern region. We researched the houses in urban area of Dalian and Haerbin which are the cities of northeast China. And we clarified the following things by this research. 1. Plan type differs greatly in dwelling units of the same scale. 2. Residents give priority to a drawing room and a master bedroom, and they tend to separate the place for a meal from them. 3. Residents tend to enjoy each other's company on the bed of the master bedroom. Such style of life which uses space for multiple purposes can be employed in a future housing plan of northern region.
