项目摘要
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.
基于性能的抗震设计(PBSD)为工程师提供了设计结构以符合特定性能要求的方法,从而在结构受到地震激励时产生更可预测的行为。PBSD需要对结构系统进行非线性分析,这需要复杂的数值模型和相当长的计算时间。因此,尽管PBSD方法的好处,PBSD在实践中没有广泛采用,除了高层建筑或安全关键结构。该项目旨在开发和实施一个开放式平台,工程师可以1)快速生成结构的非线性模型,2)根据最先进的方法在自动化过程中以最少的用户输入进行结构的抗震性能评估。拟议的研究将基于FEMA P-58中最先进的方法。在该项目中,我们计划将建筑信息模型(BIM)集成到性能评估过程中,通过提供建筑物内容的详细表示来准确和自动评估经济损失。加拿大的城市和地区都有地震危险。寻求减少地震潜在影响的措施符合国家利益。人们普遍认为,减轻未来地震影响的一个重要组成部分是设计和建造更安全和规划更好的结构。建议的研究成果将使设计师能够更合理和经济地实现这一目标。在项目完成后,行业合作伙伴将把研究结果和试点开发转化为商业软件包。因此,工程办公室可以通过与客户沟通建筑设计的优点和缺点来增加项目的价值。
