This study revealed the fundamental properties of wall clays, which were used in two mud wall storehouses, Dozoh, in Wajima, Noto. These Dozoh were subjected to the destructive earthquake occurred in March 25, 2007.
Some of the test samples were taken away from a Dozoh which was constructed in the end of the Edo period and was seriously damaged by the earthquake. The other samples were newly excavated from the area around there and then one of them was used to repair the clay wall of the other Dozoh whose framework was slightly injured.
It was found that the particle size of the wall clay used for the restoration of the Dozoh was smaller and its compressive strength was greater than those of the clay used in the other ancient one.

The authors conducted a study of aging effect on a laminated natural rubber bearing actually used in a seismically isolated building for about twenty years. No obvious change was recognized for fundamental characteristics of the rubber bearing, mechanical characteristics of inner rubber, and adhesive strength between inner rubbers and steel plates.
Also it was found that creep deformation of the rubber bearing corresponded precisely to a prediction formula.
These test results led a conclusion that natural rubber bearings would have considerable durability under long and severe environmental conditions.

The authors carried out compressive and tensile loaed tests of cast-in-place concrete nodular piles and clarified that the resistance of the pile increased by the effect of the node. And we could simulate well the vertical behavior of them by non-linear 3D-FEM.
And we adapted the simulation method to the settlement analysis for the pile foundation supporting high-rise building under dead load and seismic load. In these analytical studies, we clarified that the building load to the piles are influenced significantly by the rigidity of the foundation beams, basement walls and pile group effect.

We report the results of static friction tests between column base and foundation stone of Japanese traditional timber buildings. Through the tests, we examined the effect of the shape of the column section, rotation angle of the column, the number of loading cycles on the variation of the static friction coefficient. The friction coefficient obtained from the test ranged from 0.7 to 0.9 in the first loading cycle. Up to 30% reduction was observed in the second loading cycle. In addition, we examined the friction coefficient between column base and concrete foundation, where the reduction in the second loading cycle was more significant.

The purpose of this study is to examine the effect of wall height on performance of shear walls. There are a lot of buildings with several heights of walls in wooden house in Japan. It is said that we have to consider influence for shear wall property with low height walls.
However, there seems to be no established theory in this problem.
Therefore we conducted static loading tests of several heights of SIP shear walls. It was found from the result that the strength of low height walls was not reduced. However, we should not overlook the fact that the stiffness of low height walls is higher than standard height walls.

The rooms with void space are very effective at enlivening household interiors, but they make the realization of comfortable thermal environments extremely difficult. We advanced the development of an air supply preheating system. Operation of this system conducts base heating to a room temperature of 15°C. One anticipated effect of this system is that by reducing the load during the heating startup period, a comfortable thermal environment will be able to be realized by operating just floor heating, air-conditioning or another heat source.

This research observed built environment of low-rise apartment houses attacked by burglars by field survey. On the ground floor, the burglary risk of apartments of which balconies face the back and the side was more than three times higher than that of the front. Approximately 70 percent of the damaged windows were not naturally visible from the streets mainly obstructed by fences and partitions for protecting privacy. Moreover, approximately 90 percent of the attacked apartment houses which balconies face the side do not have enough access control for some possible intrude routes, even where directly reach the side.

In the movement of making digital archives of cultural assets, you can see the similar approaches in the architectural field. Most of these are simply creating computer graphics of outside appearance, few are precisely digitizing inside mechanism. Considering academic significance, the latter are more valuable than the former. Precisely detailed digital archive includes huge amount of three-dimensional geometric data, illustration and commentary, so that it requires sophisticated system for managing data consistency.
The authors customized a commercial 3D CAD system to interactively communicate with a backend relational database system which stores various building information. In this paper, the authors propose brand-new digital-archive method using the "CAD w/ DB" system.

Students studying to be an architect well handle virtual tools such as CAD and Illustrator, while they have slight chances to feel "real technologies". Structural experiment lecture has a potentiality to supply the senses of material quality and structural load to their mind and even to their bodies. Those senses are very important for the students to reach the threshold of architects. Proposed test method of RC beam is based on the load generated by highly elastic steel bars, i.e., PC bars. The students can feel the load level and the deformation level through the torque and the rotation of screw nuts attached to PC bars. Simple beams are tested in parallel so that even forty students are able to participate in the tests at the same time. Thus, the students feel the energy dissipation of ductile beams with their own sweats.
