|Outline and Purpose of the Course||This course will provide an overview of various meteorological phenomena causing the wind genesis to understand the wind force on building structures, and discuss the relation between flow around building and wind pressure. We explain the evaluation method of design wind load to secure the building safety against wind and the wind resistant design method based on the Building Standards Act, Building Standard Law Enforcement Order and AIJ Recommendations for Loads on Buildings.|
|Course Goals||Acquisition of expert and basic knowledge on wind resistant design. Understanding the estimation of wind load and the construction from the stand point of wind resistant design.|
|Schedule and Contents||
Mechanism of wind genesis, 4 classes:
These classes will provide an overview of the atmospheric circulation caused by the motion of the earth and the heat budget, the mechanism of wind genesis caused by low pressure system, front and topography, etc.
We will explain the characteristics of strong wind which is important for wind resistant design of building and structure with the description of its origin such as typhoon or tornado.
Basic of wind force and pressure, 4 classes:
These classes will derive the governing equations of wind flow and explain the meaning of its physics. We also obtain equations for simple flows and show equations to evaluate the wind pressure on the surface of objects.
Wind load, 3 classes:
These classes will explain the characteristics of natural wind, the observing technique and the prediction method of wind speed for wind load estimation. We discuss the calculation method of wind loads for design.
Wind resistant design, 3 classes:
These classes will explain the vibration caused by wind pressure on the walls and the design method to secure the building against wind load, and explain the calculation method of design wind load based on the Building Standards Act and AIJ Recommendations for Loads on Buildings.
Confirmation of learning attainment, 1 class:
This class will summarize the course and confirm learning attainment.
