A large portion of buildings in Canada are built with structural steel framing to resist both gravity and lateral loads. Lateral loads due to wind and earthquakes can be resisted by steel moment-resisting frames, which consist of horizontal elements (beams) and vertical elements (columns) that are rigidly connected together. Although this system is one of the most desirable for the construction of building structures, several factors associated with their constructability, cost-effectiveness and structural performance limit the use of such systems in the construction of buildings. This research project aims to develop a new steel structural system using the modular construction methodology to improve structural performance and more importantly to enhance construction efficiency, thus reducing the environmental impact of construction materials and improving productivity (reduced time and cost) for the construction of mid- and high-rise buildings in Canada. This will be achieved through comprehensive full-scale structural testing, advanced numerical simulations and construction process analyses. In collaboration with the industry partners, the project will lead to design, fabrication, transportation and erection recommendations to be used by structural engineering firms and steel fabricators in the Canadian construction industry.

加拿大的大部分建筑物都是用结构性钢框架建造的，可抵抗重力和侧向载荷。由于风和地震引起的横向载荷可以通过抗钢矩力的框架来抵抗，这些框架由水平元素（梁）和垂直元素（圆柱）组成，这些元件和垂直元素（柱）紧密地连接在一起。尽管该系统是建筑结构建设最理想的系统之一，但与其可建造性，成本效益和结构性绩效相关的几个因素限制了此类系统在建筑物建设中的使用。该研究项目旨在使用模块化构造方法来开发一种新的钢结构系统，以提高结构性性能，更重要的是提高建筑效率，从而降低建筑材料的环境影响并提高生产率（减少时间和成本），以构建加拿大中期和高层建筑。这将通过全面的全尺度结构测试，高级数值模拟和施工过程分析来实现。与行业合作伙伴合作，该项目将导致加拿大建筑行业的结构工程公司和钢铁制造商使用设计，制造，运输和勃起建议。
