Abstract

Abstract

En 中文
• Unified CSPM modelling for built-up beam, plate and beam-shell structures. • Multi-support-domain equations handle junction force and moment transfer. • Heterogeneous beam-shell coupling reduces particles for stiffened plates. • Drop-weight tests validate transient responses under impact loading. • Elastic-plastic impact case confirms robustness under local yielding.
Keywords:
