Architecture and
Building Engineering

Architecture is an important of element society that is closely related to human beings through creation of various environments. Therefore, we have great potential for creating a rich and vivid social life environment. This faculty offers comprehensive architectural education based on art, science and technology, cultivating designers and engineers who can accurately grasp requirements and tasks of the society which has entered the maturity phase, switching from “development” to “sustaining”, from “efficiency” to “humanity”, and realize and solve them both theoretically and practically. In year 2009 we have added four more education fields to existing five fields, providing more comprehensive education. This faculty allows students to study a wide range of fields, from “architecture” to “urban”.

Wind Engineering

Collecting and analyzing experimental data on
both wind load and resistance of building components in order to
reduce wind damage on residential buildings.
Associate Prof. GAVANSKI Eri

Strong wind disasters in Japan have increased dramatically
in the last ten years.

When speaking about disasters in Japan, many people think about earthquakes and floods. However, strong wind disasters are increasing more than before due to climate change in recent years. The number of large typhoons has increased, and local strong wind disasters such as tornadoes and downbursts are more likely to occur.
These phenomena are something we cannot overlook for houses where we live. Because houses are often not designed and constructed like large buildings, the Building Standard Law and load guidelines consider only typhoons and do not have specific regulations for such rare phenomena as tornadoes and downbursts. Unlike widely known seismic loads, the magnitude of wind loads changes depending on the building shape even for buildings constructed in the same area. The other notable feature of wind load is that it lasts prolonged duration, unlike seismic loads. In our laboratory we conduct wind tunnel tests using reduced scaled models to evaluate wind loads acting on buildings.

We are trying to establish evaluation methods of
wind resistance of building components.

Strong wind damages a building when the wind load applied to the building exceeds the strength of its structural members (such as columns and beams) and the cladding members (such as shutters and windows). In recent years it is the cladding members that are damaged by strong winds. Hence, the wind loads acting on houses are determined by performing wind tunnel tests with scaled building models and wind resistance performance was evaluated by full-scale breakage tests using wind pressure loading device. In order to present our results to people who are not experts in a manner that is easy to understand, we calculate the relationship between repair cost of houses and wind speed using the obtained results. Currently, our laboratory promotes testing in cooperation with various Japanese manufacturers of cladding materials. There are few Japanese universities that teach wind engineering. Therefore, let’s create a new field of wind disaster prevention in order to reduce the increasing wind-related disasters in Japan.

Architecture and Building Engineering Research Areas

Building Engineering

Education and research in the building engineering area is centered on knowledge and technology necessary to control various aspects of structural behaviors of buildings. Specifically, the education includes: (1) learning the technology of structural analysis of buildings and development of ability to create structural planning (structural mechanics, structural planning), (2) learning the basics of structural design of buildings and understanding of theoretical background (reference load, load estimation), (3) learning the basics of structural materials and construction quality control of buildings, and basic knowledge about various building structures and properties of building materials (building materials, construction quality).

Structural Engineering for Architecture

Among various architectural structures our research is focused on mechanical characteristics of shell and spatial structures with large space, represented by domes and stadium roofs. We research structural characteristics using both numerical analysis and experimental methods, aiming to develop structural technology to create new architectural space.

Wind Engineering

Earthquakes and wind force are the main affecting factors that buildings must withstand. While the force applied by an earthquake varies depending on internal characteristics of the building such as its hardness and weight, the wind force depends on the shape of the building, or, so to speak, its appearance. On the other hand, if the building is destroyed it means that (earthquake / wind force) > (building’s strength), and it is also necessary to check the structural strength of the building. Our laboratory is studying the forces generated by the winds acting on buildings and the structural strength of the buildings damaged by the wind.

Building Materials

We are researching seismic performance evaluation of buildings (mainly reinforced concrete and wooden) and development of seismic strengthening technology. Recently, our goal is to develop a new concrete structural material system which will use new materials. We are also working on development of building and structural materials with reduced environmental impact due to effective utilization of natural resources and industrial byproducts.

  • Observation of test specimen’s damage

Architectural Environmental Engineering

Education and research in the environmental area is focused on indoor and outdoor environmental control from the viewpoint of human comfort and energy conservation in architectural space. Specific fields: (1) light environment including sunshine, lighting, natural lighting, (2) heat environment including temperature and energy, (3) sound environment including noise, sound insulation, acoustic characteristics, (4) air environment including air quality and air flow, (5) quantitative evaluation of building's physics, evaluation of buildings from psychological and physiological point of view in the area of building facilities handling water supply, sanitation and fire extinguishing system, air conditioning and ventilation.

Architectural Environmental Engineering

In order to reduce the risk of fall accidents of elderly persons, we measure line of sight during movement in the light environment as an environmental factor causing such accidents. We also analyze the relationship between the rate of fall accidents in nursing homes for elderly and weather conditions.

Architecture and Planning

In addition to planning physical characteristics of buildings, education and research in the architecture and planning area is focused on planning the <architecture> by considering such aspects as human social life and historical culture. Specific fields include (1) planning including not only new constructions but also utilization of stocks and construction of buildings, (2) design that creative integrates a wide range of conditions relating to construction, (3) architectural history that updates evaluation and definition of buildings. This area puts special attention to practical approach through actual design, moving between practice and theory.

Architectural Design and History

We examine and analyze existing cities in the field and research design methods that use the results in architectural design. Our students not only participate in exhibitions, but also have many opportunities to engage in actual projects, such as designing buildings requested by the laboratory and participating in the competition of architectural design offices.

Architectural Planning and Design

Renovation has become popular as a method of regenerating the housing stock, and renovation areas have appeared all over the place. In such areas renovation calls further renovation, forming a chain network. This phenomenon is called Co-Renovation. We investigate its mechanism and the possibility of revitalizing the community. As mentioned above, the architectural planning is a research field that constructs the theory of planning buildings and cities from the relationship between humans, things and ideas.

  • The renovation leads to the birth of relationship between humans, things and ideas, starting the celebration (Abeno-ku Osaka-shi)
  • It also creates gathering places for local people (Nagasaki pref., Fukuejima)

Building Construction Method

We are working on development of new construction methods using new materials, reevaluation of traditional technologies and development of methods to diagnose soundness of existing buildings based on wooden materials and wooden structures as sustainable materials responsible for carbon fixation, development of technical infrastructure for long-term prediction of building performance.

Community Design

We perform empirical research through workshops with residents, focusing on cities as living entities comprising people, communities and regions. We are working on such themes as urban planning to revitalize cities and regions where residents play major part, and design of regional and group urban space beyond single buildings.

  • Planning, design and utilization of public spaces, social experiments and their analysis, observation and evaluation
