Performance-based Seismic Design

AIT Solutions has conducted structural performance-based design of over 120 tall buildings located in high seismic zone. For our partners & clients in these projects, AIT Solutions conducts highly detailed earthquake simulations to check and improve the structural performance as well as cost-effectiveness.

The scope that AIT Solutions carries out to evaluate the primary lateral load resisting system for specified performance objectives under different levels of earthquakes includes:

Developing the performance-based evaluation criteria, including the description of the building and its structural system, codes, standards and references, loading criteria, materials, modeling, and the prescribed analysis and design procedures.
Creating the finite element models of the building with varying complexity and refinement suitable to determine the response under gravity and seismic loads.
Carrying out different types of analyses to evaluate the performance: using linear-static, and nonlinear response history analyses. The analyses are conducted using seismic input information and ground motion records provided by the main structural engineer/client.
Carrying out detailed studies of the response and performance of primary structural members and systems in the building with the objective to improve their performance as well as cost effectiveness.
Providing recommendations based on the performance-based evaluation results. The recommendations assists the structural designer to modify/update the design.
