Analysis and Application of Single Story Ultra-High and Large-Span Lattice Beam-Column Structure
摘要
Abstract
Based on the structural scheme of a single-story ultra-high,large-span spatial building,a lattice-type beam-column structural system is proposed.Detailed layouts of the foundation and column bases,a parametric modeling workflow,recommended height-to-width ratios for ultra-high lattice columns,span-to-depth ratios for roof transverse trusses,and principles for setting roof and inter-column bracing are presented.The load transfer mechanism of the structural system is analyzed,and seismic performance-based design objectives are proposed.A global stability study of the structure is conducted using linear elastic buckling analysis on the overall model,yielding elastic buckling factors.Finite element analysis is carried out on critical joints,and cast steel joints are employed in areas with significant stress concentrations at bifurcation nodes connecting lattice columns and inverted triangular trusses,achieving the"strong joint,weak member"design philosophy.The analysis results show that the structure meets the design requirements in terms of strength,stiffness,and stability.Finally,a feasibility and steel consumption comparison between solid-web and lattice-type structural schemes is provided.The findings can serve as a reference for similar engineering projects.关键词
