Applicability of high-strength/high-fluidity concrete using eco cement to environment-conscious CFT was examined. As a result, the following conclusions were obtained. (1) Within W/C=28% or more, high-strength/high-fluidity concrete using eco cement can be placed with a usual concrete pump. (2) In the comparison with W/C=35%, high-strength/high-fluidity concrete using eco cement had a pumpability almost equal to high-strength/high-fluidity concrete using ordinarily portland cement. (3) The corrosivity of high-strength/high-fluidity concrete using eco cement with W/C=35% was smaller than that of concrete using ordinarily portland cement with W/C=50%.

After a disaster, it is needed to provide large amount of temporary houses promptly for people who lose their own houses. In this paper, a housing construction technique that is suitable for Japanese historical surroundings is proposed. It is making use of the Japanese traditional plaster technique inherited for hundreds years. And the frame of this system is the shell structure that is one of the most efficient structural system, therefore, it can be build with very little amount of material.

Wood is the one of three main construction materials. Comparing to other two, Iron and Concrete, recycling rate of wood is low and its material flow is not clear yet. One reason of such situation is that there are so many recycling methods of wood. In this research, we tried to make real situation clear concerning about wooden construction materials which manufactured in Akita prefecture. Then we tried to evaluate effects of recycling in some lumber factories using Life Cycle Assessment tool.

The authors attempted to develop a plant-base geomaterial with vibration damping capability against earthquake motion using industrial wastes and construction by-products. This geomaterial will contribute not only to seismic vibration damping but also to urban greening. The mechanical properties of the geomaterial through the results of unconfined compressive test and cyclic triaxial test were discussed in this paper. The geomaterial mixed with wood-chips, recycled fine component and emulsified asphalt was a suitable target of the research.

A new base-isolation system for detached houses is proposed and the results of its full-scale shaking table tests are reported. The new system is based on the concept of the “gage pendulum”. In order to examine the performance of the new base-isolation system a series of full-scale shaking table test with a real detached house was carried out. After the tests the house was directly connected to the foundation and another series of shaking table tests, without base-isolation, was carried out for the comparison. The results show the high performance of the proposed base-isolation system.

In this paper, a laddery beam with high damping viscoelastic dampers is proposed to enhance seismic capacity of traditional timber structures. To make clear the effect of the reinforcement member, shaking table tests were conducted in the Disaster Prevention Research Institute, Kyoto University. As a result, a laddery beam with high damping viscoelastic dampers increased damping ratio and reduced response, compared with those without dampers. The laddery beam with viscoelastic dampers tested was proven to have effectiveness in enhancing seismic performance of traditional wooden frames during earthquakes.

The method for evaluating the difference of SPT N-values is investigated based on the nine SPT at the same site, and the trial design on bearing capacity of the pile considering the SPT N-values variations is conducted. It is shown that (1) The coefficient variation of the average N-values of the layers is comparatively small, though the coefficient variation that uses all N-values is very large; (2) The bearing capacity of the pile obtained from the limit state design is larger than the allowable stress design, if the difference of the ground constants is appropriately evaluated.

A new type of moment resisting timber joint has been developed. The joint is made up of steel plates, bolts and steel cotters. The plates and the bolts are embedded with timber element of frame structure. By combining those elements with steel cotters, moment resisting joints can be constructed easily. Static loading tests of the joint have been performed, and results of the tests made it clear that the joint have rotational rigidity and strength required from constructing moment resisting frame. And when we design the structure of wooden residence, we must use the shear elements. So, we simulate of shear-displacement curves of shear elements. In this paper, we show the results.

When concrete of 100 N/mm
2 class is used so that outside columns of a high-rise building may receive a high axis load, concrete at the edge of an R/C column member is violently crushed by compressive force at a story drift angle of 1/200 - 1/100 rad. To prevent this, as there were problems in structural performance as strength rapidly decreased, 1 - 2 vol.% steel fiber was mixed in to reinforce the precast concrete shell R/C column. As a result: (1) Crushing of concrete at the edge of the member and exfoliation of cover concrete were decreased. (2) Deformation capacity increased in a straight line as the steel fiber content increased and that increase was 20 % when the steel fiber content was 2 %. (3) It is conjectured that the flexural ultimate strength increased about 25 %.

Carbon fiber sheet (CF sheet) is widely used in seismic strengthening for existing R/C buildings. But shear failure is considered to occur in R/C column even if it is strengthened by CF sheet. In the current seismic retrofit standard, effect of CF sheet is only evaluated if the increasing in ultimate strength is observed. However, some past experimental studies showed the ductility of RC column is improved by CF sheets even if the strength does not increase.
This research is aiming to propose the rational evaluation for the improving in ductility of RC column by CF sheets which is failed in shear. FEM analysis was used in this examination, and the followings are obtained.
1) There is upper limitation between the amount of the total shear reinforcement(Σp
w • σ
wy) and the ductility.
2) The improvement in ductility reaches upper limit when the ratio of the total shear reinforcement to upper bound shear strength ((Σp
wσ
wy)/(υ σ
B/2)) becomes unity.

Loading tests for sustainable building structural system on the past studies have not considered the axial force applied to the beam-to-column connection. These tests have also not considered the change in the rigidity with the floor. Therefore, the effectiveness of the axial force and the floor was indefinite. This study verifies the effectiveness of the floor and the axial force by the behavior of the specimens that set partial frames for sustainable building structural system of one layer one span.

This paper describes static cyclic loading tests of buckling restrained braces using steel mortar planks with initial imperfections. Experimental parameters are initial deflection of core plates due to uneven of mortar face and direction of core plates. Tests are conducted by applying increasing loads alternately in positive and negative directions. As results, the energy absorption capacity of specimens with initial imperfection is lower than that without initial imperfection; however, the absorption capacity is larger than that of required value.

The building facade plays important role for not only creating urban landscape design, but also affecting the.. environmental impact through energy consumption. Also such perimeter zones are effective area for providing seismic resisting elements in structural design. For satisfying all of these demands, the authors proposed the concept of integrated facade engineering, which treats architectural design, structural and environmental design combined together. Following the previous papers, other detailed examples of Integrated Facade are proposed in this paper, and their structural performance is evaluated through mock-up experiments.

The present Japanese code for resist-seismic-load requires that ordinary buildings have to behave elastically during level-1 earthquakes, and as collapse-free structures against level-2. On the other hand, there have been some reports on the events of heavy-furniture-downfalls in buildings even level-1 earthquakes. Such the furniture downfalls could cause the serious accidents resulting in injury or death. The movement called the “KAGUTENBOU-TAI” based on students' volunteer work has been launched about half and two years ago for the purpose of preventing heavy-furniture-downfalls during level-2 earthquakes. In this paper, we reported on the philosophy, history and estimation of this movement, and also discussed its challenges and foresight for the future.

This paper attempts to reveal the characteristic tendencies in the livelihood and community perception among nomads in relation to their living environment. For this, comparative analysis was performed on the living environments and characteristics of the perception of livelihood, community activities, etc., among the apartment settlers (urban dwellers) and nomads in the subject region after identifying them from the findings from questionnaire surveys.
As a result, the following matters were discovered:
1) The nomads are highly aware of the nomadic life as they are leading today. This perception correlates with their high consciousness of the life in which they are involved closely in neighboring households. 2) The nomads are highly aware of the natural environment and also the transmission of the rich natural environment to posterity. 3) The nomads are highly appreciative of and satisfied with the nomadic life overall, which shows its correlation with the rich natural and child-rearing environments and their high community perception.
