Performance-based seismic design method based on Building Information Modelling

The performance-based seismic design (PBSD) provides engineers with the means to design a structure to comply with specific performance requirements, leading to more predictable behaviour when the structure is subjected to earthquake excitation. The PBSD requires nonlinear analyses of a structural system that requires a sophisticated numerical model and considerable computing time. Thus, despite the PBSD method's benefits, the PBSD is not widely adopted in practice except for high-rise buildings or safety-critical structures. The proposed project aims to develop and implement an open platform with which engineers can 1) quickly generate a nonlinear model of a structure, and 2) conduct a seismic performance assessment of the structure according to the state-of-the-art methods in an automated process with minimum user input. The proposed research will be based on the state-of-the-art methodology in FEMA P-58. In this project, we are planning to integrate Building Information Modelling (BIM) in the performance assessment process for accurate and automatic evaluation of economic loss by supplying a detailed representation of a building's contents. Canadian cities and territories are subject to seismic hazards. It is in the interest of the country to seek measures to reduce the potential impact of earthquakes. It is generally accepted that an essential part of mitigating future earthquakes' impact is designing and constructing safer and better-planned structures. The proposed research outcomes will allow designers to achieve this more rationally and economically.Upon completing the project, the industry partner will translate the findings and the pilot developments into a commercial software package. Thus, engineering offices can add value to their projects by communicating with their clients the benefits and drawbacks of building design in quantitative terms.
