The effect of inter-connection properties on the lateral behaviour of moment-frame modular steel structures

摘要: Recently, there has been a push for the adoption of pre-fabricated modular units in constructing low to high-rise buildings mainly due to the reduction of material waste and construction time. These units are manufactured in a factory and then transported to the construction site for assembly through inter-connections to create a building block. The unique nature of these inter-connections is crucial for the structural performance of modular buildings as they provide modular structure integrity. Despite the growing popularity of modular construction, there is a limited number of published studies examining how inter-connection mechanical characteristics influence the lateral performance of moment-frame modular structures. The stiffness of inter-connections plays a crucial role in determining the overall rigidity of these structures, indicating the importance of studying their impact on the seismic performance of moment …
