Structural systems for modular integrated construction: Review and comparative analyses

Modular integrated construction (MIC) has gained more popular attentions from both researchers and engineers due to its advantages of construction efficiency and environmental friendliness. The paper conducted a comprehensive review study on different structural systems for MIC including fully modular structure (FMS), mixed modular structure (MMS) and in-fill modular structure (IFMS), the architectural, structural and constructional characteristics are discussed in detail for each modular structure with typical applications. Afterwards, one innovative IFMS based on sparse-component frames (IFMS-SCF) was proposed and comparative analyses were provided between IFMS-SCF and previous modular structures. Results reveal that different modular structures vary greatly in their principal lateral resisting structures, applicable height, construction efficiency and architectural flexibility. IFMS-SCF can be one promising structural system used for high-rise MIC with enhanced construction efficiency and great potential in the brand-new residence style.
