ASCE Seismic Evaluation and Retrofit of Existing Buildings is rapidly becoming the main standard being used for seismic evaluation and retrofit of existing buildings.
This standard establishes analysis procedures and acceptance criteria, and specifies requirements for foundations and geologic site hazards; components made of steel, concrete, masonry, wood, and cold-formed steel; architectural, mechanical, and electrical components and systems; and seismic isolation and energy dissipation systems.
This webinar provides a brief introduction to ASCEfollowed 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 asde Tier 2 and Tier 3 procedure. However, it includes considerable changes and improvements over the predecessors.

Seismic Evaluation of Existing Buildings Using ASCE Tier 2 and Tier 3 Procedures (AWO)
The ascw evaluation and retrofit process per ASCE consists of three Tiers including, Tier 1 screening procedure, Tier 2 deficiency-based evaluation procedure, and Tier 3 systematic evaluation procedure. System Requirements for Viewing this Course.
The deficiency-based procedures allow evaluation and retrofit efforts to focus on specific potential deficiencies deemed to be of concern for a specified set of building types and heights. Checklists are provided for a variety of building types and seismicity levels in support of the Tier 1 screening process.

It also discusses the limitations of Tier 2 and pros and cons of Tier 2 versus Tier 3. Many building officials and jurisdictions have either adopted this standard or in the process of reviewing and adopting it.
Tier 3 systematic evaluation Tier 3 scope, limitation, and procedure Tier 3 general requirements Tier 3 data collection Tier 3 analysis methods Tier 3 evaluation outcome Questions. 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.
It revises the nonlinear dynamic procedure and changes provisions for steel and concrete columns, as well provisions as for unreinforced masonry.
The standard presents a three-tiered process for seismic evaluation according to a range of building performance levels by connecting targeted structural ascs and the performance of nonstructural components with seismic hazard levels. 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.
The systematic procedure, applicable to any building, sets forth a methodology 41-113 evaluate the entire building in a rigorous manner.
