The modern era is a period in which the globalization of architecture advanced against a background of dramatic technological innovation. In that process, what has architecture taken and what has it left behind? We give thought to what constitutes the essential center from various social contexts surrounding architecture.

Ichizo KISHIMOTO

Position
Professor
Laboratory
Concrete Structure/Material Laboratory
Concrete Structures

We do research on the earthquake resistance and durability of concrete structures. For example, in a study working in collaboration with a private company, we investigated the performance of concrete structural members using high-strength shear reinforcement (rebar wound around the interior of columns and beams of a building) developed by the manufacturer. In addition, we are working on a study of concrete cracking from the perspective of durability and aesthetics. This research is attractive because the need is strong in the real world and is relevant to people’s lives.

We are working broadly on urban management in an aging society and low-carbon society from both a theoretical and practical perspective. In particular, we are studying town planning by the residents themselves that applies urban management techniques.

Hiroshi NODA

Position
Professor
Laboratory
Wind Engineering Laboratory
Wind Engineering, Computational Fluid Dynamics, Risk Assessment

As seawater temperatures near Japan have risen in recent years, disaster damage caused by powerful winds, for example, typhoons and tornadoes, has been increasing. We study the safety of buildings with respect to strong winds and the strong winds themselves.

Professor
Laboratory
Laboratory of Composite Structural Engineering
Structural Engineering, Bridge Engineering, Maintenance Engineering

For the sake of safe, reliable and comfortable living, we research the development of new materials and structures, investigate methodologies, and study maintenance of existing structures. We deepen our understanding by examining phenomena, touching on materials and structures in experiments and analysis.

Takaahiro HISA

Position
Professor
Laboratory
Social System Laboratory
Urban planning、Urban design、Community design

Kazuaki MATSUI

Position
Professor
Laboratory
Environmental Biological Science Laboratory
Microbial Ecology, Evaluation of Impacts on Microbial Ecosystems

We are working on a variety of research projects to understand the microbial ecosystems. We isolate and characterize spore-forming mercury resistant bacteria to understand the dissemination nature of the mercury resistant transposon among bacteria. We also try to elucidate the quantitative relationship between biodiversity and ecosystem functioning with microbes.

Masahide MURAKAMI

Position
Professor
Laboratory
Timber Structure Laboratory
Timber Structures

A variety of construction methods exist for wood structures. In addition, wood is a biological material, and thus, material strength is also uncertain. Consequently, the theory of structural design is still underdeveloped compared to reinforced concrete and steel-frame construction. We have adopted a research theme of developing computational theories and evaluating structural performance that will be beneficial in the structural design of various load-bearing elements. Since it is difficult to theoretically elucidate the full behavior of wood structures, we focus our research on tests of actual full-size structures.

Kentaro YAMAGUCHI

Position
Professor
Laboratory
Housing for Life and Well-Being Laboratory
Architecture Planning

In manufacturing, it is essential to get a picture of user needs and lifestyles. Using a variety of research methodologies, we gauge the needs of people who have difficulty in making their wishes known, for example, the elderly and the disabled, and study what is desirable in products, architecture, and communities from the standpoint of these people. In particular, we are undertaking comprehensive research on facilities for the elderly, from assistive devices and equipment to buildings and regional planning.

Masahiro YONEDA

Position
Professor
Laboratory
Bridge Engineering Laboratory
Bridge Engineering, Structural Engineering, Structural Dynamics

Bridges that hold up and survive, even when typhoons with wind speeds of 80 meters per second arrive, and also when earthquakes of magnitude 8 strike. Bridges for which no shaking occurs that will cause discomfort when vehicles pass by or when people are walking. We do research on such bridges.
