Modular construction is a relatively new concept of constructing buildings and other infrastructures. It is similar to building a toy house using LEGO-style building blocks. Using the modular construction method, the blocks of a real building are built offsite (in a factory) and shipped to a construction site to be put together. The modular construction method is a much cheaper and faster alternative to traditional onsite construction methods. It ensures better quality control on constructions since a significant amount of the construction work is completed in the factory under strict supervision and quality control. When the building's blocks reach the construction site, they are put together using easy-to-use but strong and durable connectors. Such connectors, namely Vectorbloc and Megabloc connectors, are being developed by VectorBloc Corp. These connectors and the connection method are being developed for constructing various buildings and other structures using hollow structural steel (HSS) members, often known as steel tubes. Steel tubular members are not commonly used in current constructions even though they have many advantages over commonly used hot-rolled steel members. In the proposed research project, beam-to-column connections using such connectors will be tested in a lab and simulated using a computer modeling technique. Upon successful completion of the research project, a concept design of an innovative modular steel construction method will be validated through sound research at the University of Windsor under the supervision of Professor Sreekanta Das. This modular construction technique will be a cheaper and faster alternative to other construction methods. It is believed that the new modular construction method will revolutionise the construction industry through the use of steel tubular members. The industry partner of this research project, VectorBloc Corp., will be able to implement and expand their construction business rapidly, and will thus be able to create new job opportunities at various skill levels, ranging from construction personnel to engineers, boosting Ontario and Canada's economy.

模块化建筑是建造建筑物和其他基础设施的一个相对较新的概念。这类似于使用乐高风格的积木建造玩具房子。使用模块化建造方法，真实的建筑物的块在场外（在工厂中）建造，并被运送到建筑工地组装在一起。模块化施工方法是传统现场施工方法的一种更便宜，更快的替代方法。由于大量的建筑工程均在严格的监督及质量控制下于工厂内完成，因此确保更佳的施工质量控制。当建筑物的块到达施工现场时，它们使用易于使用但坚固耐用的连接器组装在一起。这种连接器，即VectorBloc和Megabloc连接器，正由VectorBloc公司开发。这些连接器和连接方法正被开发用于使用中空结构钢（HSS）构件（通常称为钢管）建造各种建筑物和其它结构。钢管构件在当前的建筑中并不常用，尽管它们与常用的热轧钢构件相比具有许多优点。在拟议的研究项目中，使用这种连接器的梁柱连接将在实验室中进行测试，并使用计算机建模技术进行模拟。在研究项目成功完成后，一个创新的模块化钢结构建筑方法的概念设计将在Sreekanta Das教授的监督下在温莎大学通过合理的研究进行验证。这种模块化施工技术将是其他施工方法的一种更便宜、更快的替代方法。人们相信，新的模块化施工方法将通过使用钢管构件彻底改变建筑业。该研究项目的行业合作伙伴VectorBloc Corp.，将能够迅速实施和扩大其建筑业务，从而能够创造各种技能水平的新就业机会，从建筑人员到工程师，促进安大略和加拿大的经济。
