Structural Performance-based Design Peer Review

Structural Performance-based Design Peer Review Structural Performance Based Design Peer Review is a process whereby a design project or an aspect of it is reviewed and evaluated by a person, or team, not directly involved with the project, but appropriately qualified to provide input that will either reinforce a design solution, or provide a route to an improved alternative.

With the rise in use of performance based structural design, the peer review process has become almost universally accepted to safeguard that performance based designs meet the commitment, not only the context or letters, provided by the building codes.

Why Structural Performance Based Design Peer Review?

Performance-based design review

Structural performance based design peer review for a building is to ensure that the structure meets the stated performance objectives and provide a level of public safety.

AIT Solutions has evaluated structures to determine whether the overall performance and reliability of the building will satisfy public safety and cost-effectiveness under the effects of gravity, wind, and different levels of earthquakes.

The performance-based design peer review is carried out after completion of performancebased design by structural consultant (EOR).

Structural consultant will submit the final architectural and structural drawings based on performance-based design.

Scope of Solutions The scope of work conducted as part of these Solutions is as follows:

Early engagement At the beginning of the project, schematic design is reviewed in close collaboration with the project architects and structural engineers. i.

Review the architectural and structural drawings provided by the client and other related documents as necessary.

ii. Study and comment on suitability of structural concepts/ systems with an objective to achieve good performance and cost effectiveness.

Independent review

i.

Develop the performance-based evaluation criteria, including seismic design methodology, seismic performance goals, acceptance criteria, mathematical modeling and simulation.

ii. Create linear and nonlinear finite element models of the structure. iii. Carry out different types of analyses to evaluate the performance: progressively using linear-static, nonlinear static and nonlinear-dynamic analyses, as appropriate.

The analyses will be conducted using site-specific response spectrum and sitespecific ground motion records, provided by the client. iv. Carry out detailed studies of the response and performance of primary structural members and systems in the structure. v. Report on the performance-based evaluation results, and comments.

Structural Performance-based Design Peer Review

Review of calculations The performance-based design peer review is carried out in line with the design phases done by project structural engineers to facilitate the design process and minimize the multiple design iterations. i.

At the beginning of project, review the basis of design, earthquake hazard determination, ground motion characterizations, seismic design methodology, seismic performance goals, acceptance criteria, wind tunnel test results and other documents as necessary.

ii. Review linear analysis models used for wind, Design Earthquake, Service Level Earthquake analyses and nonlinear analysis model used for Maximum Considered Earthquake analysis when structural consultant (EOR) completes the models.

iii. Review design calculations of structural components for wind, Design Earthquake, and Service Level Earthquake submitted by structural consultant (EOR). iv. Review design report for Maximum Considered Earthquake evaluation submitted by structural consultant (EOR). v. Review final working structural drawings. vi. Report on the peer review comments and recommendations.

Deliverables The following reports will be submitted to the client.

1. Recommendation for improvement 2. Performance letter 3. Cost performance analysis
