FEA Applications in PPVC and MET Steel Modules for Singapore Megaprojects

FEA Applications in PPVC and MET Steel Modules for Singapore Megaprojects

Key Takeaways Finite element analysis (FEA) helps modular construction teams test structural behavior before fabrication, lifting, transport, and installation. In Singapore, its value is greatest when it is connected to DfMA decisions, authority requirements, and practical fabrication constraints. FEA links structural design with manufacturing and assembly decisions. PPVC and MET steel modules require different modeling […]

Linear vs. Non-Linear Analysis in Steel Design: When Is Elastic Analysis Not Enough?

Linear vs. Non-Linear Analysis in Steel Design: When Is Elastic Analysis Not Enough?

Key Takeaways Linear elastic analysis remains a practical foundation for many steel designs, but it should not be treated as a universal description of structural behavior. Linear analysis assumes proportional loading, small displacements, constant stiffness, and elastic material response. Nonlinearity may arise from yielding, geometric instability, buckling, contact, friction, or connection behavior. Second-order effects and […]
