Performance-based design is a major shift from traditional structural design concepts and provides a method for determining acceptable levels of earthquake damage. Also, it is based on the recognition that yielding does not constitute failure and that preplanned yielding of certain members of a structure during an earthquake can actually help to save the rest of the structure. This course provides the theory and practical application of nonlinear analysis and performance-based design of tall buildings.

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

• Understand the concepts of performance based
• Carry out performance based seismic assessment of tall

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.
