Mid-to High-Rise Modular Steel Construction

模块化钢结构是钢结构的另一种施工方法，其中单个完整单元在工厂预制，并在现场组装，以生产永久性住宅和商业建筑。模块化钢结构具有许多优点，例如提供快速的投资回报，具有更好的质量控制和更环保。目前在加拿大应用的模块化钢结构主要包括高度不超过三层的结构。为了使中高层建筑能够用这种方法建造，有必要关注它们在动态载荷（即风和地震）下的横向载荷抵抗力。虽然模块化钢结构建筑与传统的钢结构建筑有很大的不同，但在加拿大的设计规范中没有对它们进行规范。凭借业界合作伙伴的设计经验，以及多伦多大学研究团队在结构动力学和地震工程方面的专业知识，拟议的研究将集中在高层模块化钢结构的设计和动态行为上。这项合作研究的结果有可能在保护环境的同时扩大加拿大建筑市场。

Modular steel construction is an alternative construction method for steel structures where individual complete units are prefabricated in a factory and are assembled on site to produce permanent residential and commercial buildings. Modular steel construction has many advantages, such as providing a fast return of investment, has better quality control and is more environmentally friendly. The current application of modular steel construction in Canada mainly consists of structures not more than three-stories in height. To enable construction of mid-to high-rise buildings with this method, it is necessary to focus on their lateral load resistances under dynamic loading (i.e, wind and earthquakes). Although modular steel buildings are considerably different than the traditional steel counterparts, there are no specifications for them in Canadian design codes. With the design experience of the industry partner, and the expertise of University of Toronto's research team in structural dynamics and earthquake engineering, the proposed research will focus on the design and dynamic behaviour of high rise modular steel structures. The results of this collaborative research have the potential to expand the Canadian construction market while safeguarding the environment.
