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.

Seismic Evaluation of Existing Buildings Using ASCE Tier 2 and Tier 3 Procedures (AWO)

Seismic Evaluation and Retrofit of Existing Buildings 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.

Procedure and details of Tier 1 screening procedure has been presented in a prior evaluation. ASCE Seismic Evaluation and Retrofit of Existing Buildings is rapidly becoming the main standard sace used for seismic evaluation and retrofit of existing buildings.

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.

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.

Checklists are provided for a variety of building types and seismicity levels in support of the Tier 1 screening process. Tier 2 deficiency-based evaluation A brief overview of Tier 1 screening procedure Tier 2 scope, limitation, and procedure Tier 2 general requirements Tier 2 condition assessment Tier 2 analysis methods Tier 2 evaluation outcome Part 4: It also discusses the limitations of Tier 2 and pros and cons of Tier 2 versus Tier 3.

Evaluation requirements Performance objectives Seismic hazard level Level of seismicity As-built information Common building type Part 3: It revises the nonlinear dynamic procedure and changes provisions for steel and concrete columns, as well provisions as for unreinforced masonry.

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 41-1 on those deficiencies. The seismic 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.

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.

However, it includes considerable changes and improvements over the predecessors. The systematic procedure, applicable to any building, sets forth a methodology to evaluate the ascs building in a rigorous manner. This new edition, which updates and replaces previous editions of ASCE 41, introduces revisions to the basic asxe objectives for existing buildings and to the evaluation of force-controlled actions.

The standard presents a three-tiered process for seismic evaluation according to a range of building performance levels by connecting targeted structural performance and the performance of nonstructural components with seismic hazard levels.

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.

Many building officials and jurisdictions have either adopted this standard or in the process of reviewing and adopting it.
