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

在加拿大，很大一部分建筑是用结构钢框架建造的，以抵抗重力和横向荷载。由水平构件(梁)和垂直构件(柱)刚性连接在一起的钢结构抗弯框架可以抵抗风和地震造成的横向荷载。虽然该系统是建筑结构最理想的系统之一，但与其可施工性、成本效益和结构性能有关的几个因素限制了这种系统在建筑物建造中的使用。这项研究项目旨在开发一种新的钢结构系统，使用模块化建造方法来改善结构性能，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，并提高加拿大中高层建筑的建造效率(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。在与行业合作伙伴的合作下，该项目将产生设计、制造、运输和安装建议，供加拿大建筑业的结构工程公司和钢铁制造商使用。

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.
