Seismic Assessment of Existing Buildings: IEP, ISA, & DSA

This course, "Seismic Assessment of Existing Buildings," provides essential knowledge for structural engineers, from recent graduates to experienced professionals, on evaluating and strengthening existing structures against seismic activity. Focusing on the technical guidelines established by the New Zealand Society for Earthquake Engineering (NZSEE), the course delves into the intricacies of seismic assessment, differentiating between Initial Seismic Assessments (ISAs) and Detailed Seismic Assessments (DSAs).

You will gain a comprehensive understanding of:

• The challenges inherent in seismic assessment and why existing buildings pose unique difficulties.
• Key terminology, including "earthquake prone" definitions and what constitutes a "moderate earthquake."
• The relationship between seismic assessment, life safety, and the risks associated with earthquake-prone buildings.
• Practical aspects of conducting ISAs and DSAs, from desk studies and non-intrusive visual inspections to more advanced intrusive investigations and material testing.
• Legal responsibilities and obligations under building acts concerning earthquake-prone buildings.
• Strategies for seismic strengthening, including minimum requirements and recommended practices for improving structural performance.
• Guidance on advising building owners regarding occupancy of earthquake-prone buildings, emphasizing the distinction between building damage and life safety.
• Insights into the "big red book" guidelines (NZSEE documents), including the Initial Evaluation Procedure (IEP) spreadsheet and its application.
• Common critical and severe structural weaknesses and how they impact a building's seismic performance.

By the end of this course, you will be equipped to confidently perform seismic assessments, interpret results, and propose effective strengthening solutions for existing buildings, ensuring compliance and enhancing public safety.
