Outline and Purpose of the Course This course will explain wind characteristics which is essential to wind resistant design of architecture and evaluation of wind environment including the mechanism of wind genesis and the effect of weather condition, topography and surface roughness. The characteristics of strong wind of typhoon or tornado causing damage to buildings is discussed. We will provide an overview of strong wind damage and explain the method of damage mitigation and disaster prevention. We will discuss the flow around building, the wind pressure and force on building, and the vibration of building caused by wind. We will provide a short history of wind resistant design and some exercises of calculating wind load on building.
Course Goals Acquisition of knowledge on prediction and evaluation for wind load and wind environment around new construction planned building.
Schedule and Contents Mechanism of wind genesis and wind characteristics, 3 classes:
This course will explain the mean and instantaneous wind speed, i.e. the characteristics of wind in atmospheric boundary layer, which is essential to wind resistant design of architecture. We will discuss the cause of wind genesis by examining the forcing mechanism and the balancing wind speed and direction.

Strong wind disaster in Japan and its characteristics, 2 classes:
This course will explain the strong wind characteristics of typhoon and tornado causing damage to buildings and houses by comparing other natural disasters. We will have an overview of historical strong wind damage in Japan and explain the features.

Wind flow around object, 2 classes:
We will discuss the foundation of fluid dynamics describing the flow around a body which is essential for the evaluation of wind load on buildings and demonstrate the wind flows around buildings and houses.

Method of wind environment prediction - 1, 1 class:
This class will drive the similarity law for wind tunnel test using scale models which is one of useful tools for wind load evaluation. We will also explain the wind tunnel test.

Method of wind environment prediction - 2, 2 classes:
These classes will explain the foundation of fluid dynamics and provide the examples of calculation.

History of wind resistant design and wind load evaluation, 2 classes:
These courses will provide an overview of the history of wind load evaluation in the Recommendations for Loads on Highrisebuildings.

Procedure of wind load evaluation based on the Building Standards Act and AIJ Recommendations for Loads on Buildings, 2 classes:
These courses will provide the evaluation method of design wind load on real buildings based on the Building Standards Act, Building Standard Law Enforcement Order and AIJ Recommendations for Loads on Buildings and practical training of calculation. We will explain the cautionary note on strong wind cause by tornado such as the wind glass breakage which is not include the law.

Confirmation of learning attainment, 1 class:
This class will summarize the course and confirm learning attainment.
Evaluation Methods and Policy By reports or examination
Course Requirements Architectural structural engineering, fluid dynamics and meteolorogy will be desirable but not be obligated.
Study outside of Class (preparation and review) To be indicated during the lecture.
