Wind excitations are a major dynamic loading for many modern civil engineering structures, hence there is a need for civil engineers to learn more about these loadings and their complex nature. The main objective of this course is to provide an improved understanding of these loadings that will enable design engineers to ensure the safety and serviceability of structures.

The students on the completion of this course would be able to:

• Analyze the wind load and evaluate aerodynamics effects and the underlying uncertainties and characteristics of
• Solve the design problems due to wind loading in design of tall
• Determine the structural loads, cladding pressures, and evaluate occupant and pedestrian comfort under wind

An “A” would be awarded if the student demonstrates thorough knowledge of concepts and techniques together with a high degree of skill and originality in the use of those concepts and techniques. A “B+” would be awarded if the student demonstrates thorough knowledge of concepts and techniques together with a fair degree of skill in the use of those concepts and techniques. A “B” would be awarded if the student demonstrates good level of knowledge of concepts and techniques with considerable skill in using them. A “C+” would be awarded if the student demonstrates that more efforts is required in relation to the required knowledge of concepts and techniques. A “C” would be awarded if the student demonstrates that intensive efforts is needed in relation to the required knowledge of concepts and techniques. A “D” would be awarded if the students’ understanding of the concepts and techniques is unacceptably low.
