This webinar was co-sponsored by ASCE's Structural Engineering Institute (SEI) and ASCE Continuing Education
Instructor: Mohammad Aliaari, Ph.D., S.E., P.E., M.ASCE
Course Length: 90 Minutes
Purpose and Background
ASCE 41-13 (Seismic Evaluation and Retrofit of Existing Buildings) is rapidly becoming the main standard being used for seismic evaluation and retrofit of existing buildings. Many building officials and jurisdictions have either adopted this standard or in the process of reviewing and adopting it. This standard is an update to earlier standard ASCE 41-06 and supersedes standard ASCE 31-03 by combining the two standards into one. However, it includes considerable changes and improvements over the predecessors.
The seismic evaluation and retrofit process per ASCE 41-13 consists of three Tiers including, Tier 1 screening procedure, Tier 2 deficiency-based evaluation procedure, and Tier 3 systematic evaluation procedure. A Tier 1 screening procedure is usually carried out first to quickly identify potential structural deficiencies, after which a detailed Tier 2 evaluation can be performed focusing on those deficiencies. Alternatively, a full detailed Tier 3 systematic evaluation can be chosen either after a Tier 1 and Tier 2 evaluation or directly from the beginning.
Procedure and details of Tier 1 screening procedure has been presented in a prior evaluation. This webinar provides a brief introduction to ASCE 41-13, followed by a detailed presentation about Tier 2 deficiency-based evaluation procedure, and Tier 3 systematic evaluation procedure. The webinar discusses in detail the evaluation requirements, performance objectives, seismic hazard levels, on-site investigation requirements, and other steps of a Tier 2 and Tier 3 procedure. It also discusses the limitations of Tier 2 and pros and cons of Tier 2 versus Tier 3.
Primary Topics of Discussion
- Overview of ASCE 41-13, its scope and application
- Seismic evaluation process using 3-tiered system
- Performance objectives and seismic hazard
- Tier 2 deficiency-based procedure and limitations
- Tier 3 systematic evaluation

- Questions
How to Earn your CEUs/PDHs and Receive Your Certificate of Completion
To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 1 year of purchasing the course.
How do I convert CEUs to PDHs?
1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
