Innovative modular steel structural system for construction of multi-storey buildings

加拿大的大部分建筑都是用钢框架结构建造的，以抵抗重力和横向荷载。由于风和地震引起的侧向荷载可以由钢抗弯矩框架来抵抗，它由水平元素（梁）和垂直元素（柱）刚性连接在一起组成。虽然该系统是建筑结构施工中最理想的系统之一，但与可施工性、成本效益和结构性能相关的几个因素限制了这种系统在建筑中的使用。本研究项目旨在开发一种新的钢结构系统，使用模块化施工方法来提高结构性能，更重要的是提高施工效率，从而减少建筑材料对环境的影响，提高加拿大中高层建筑的生产率（减少时间和成本）。这将通过全面的全尺寸结构测试、先进的数值模拟和施工过程分析来实现。通过与行业合作伙伴的合作，该项目将为加拿大建筑行业的结构工程公司和钢铁制造商提供设计、制造、运输和安装建议。

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.
