Procedure and details of Tier 1 screening procedure has been presented in a prior evaluation.

Seismic Evaluation and Retrofit of Existing Buildings 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.

Alternatively, a full detailed Tier 3 systematic evaluation can be ase either after a Tier 1 and Tier 2 evaluation or directly from the beginning.

Many building officials and jurisdictions have either adopted this standard or in the process of reviewing and adopting it. Keyword s Codes and Standards;Materials;Structural.

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 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.

The systematic procedure, applicable to any building, sets forth a methodology to evaluate the entire building in a rigorous manner. 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.

System Requirements for Viewing this Course.

This new edition, which updates and replaces previous editions of ASCE 41, introduces revisions to the basic performance objectives for existing buildings and to the evaluation zsce force-controlled actions.

Checklists are provided for a variety of building types and seismicity levels in support of the Tier 1 screening process.

ASCE Seismic Evaluation and Retrofit of Existing Buildings is rapidly becoming the main standard being used for seismic evaluation and retrofit of existing buildings. Evaluation requirements Performance objectives Seismic hazard ase Level of seismicity As-built information Common building type Part 3: 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.

Seismic Evaluation and Retrofit of Existing Buildings (41-17)

However, it includes considerable changes and improvements over the predecessors. A Tier 1 screening procedure is usually carried out first to quickly identify potential structural deficiencies, after which a detailed Tier 411-13 evaluation can be performed focusing on those deficiencies.

It revises the nonlinear dynamic procedure and changes provisions for steel and concrete columns, as well provisions as for unreinforced masonry. It also discusses the limitations of Tier 2 and pros and cons of Tier 2 versus Tier 3. 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.

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. Tier 2 deficiency-based evaluation 411-3 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:
