Mechanical Performance Analysis of Fully Bolted Spliced Joints in Modular Steel Frame Structures
摘要
Abstract
A novel approach for fully bolted splicing between modular steel frame modules is proposed,which achieves the all-bolt assembly through the inter-module connecting keys,blind bolts,and through bolts.To investigate the mechanical properties of this spliced joint,a refined numerical model of the fully bolted spliced joint between modular steel frame modules was established using the ABAQUS finite element software.Low-cycle reversed loading simulations were conducted to analyze the hysteretic curve,skeleton curve,ductility,energy dissipation and bearing capacity of the joint.A computational model for the initial rotational stiffness of the joint was proposed,and the corresponding formula was derived.The accuracy of this formula was subsequently validated through a comparative analysis with numerical simulation results.The research findings indicate that the design of the fully bolted spliced joint is structurally rational.The corner keys at the beam ends enhance the joint stiffness and promote the outward migration of plastic hinges at the beam ends,enabling ductile failure of the joint.The hysteretic curves of the joint specimens exhibit a full spindle shape,indicating strong energy dissipation capabilities.The inter-story drift angles and ductility factors of the joint specimens both meet the relevant seismic design requirements,demonstrating good seismic performance.Increasing the thickness of the connecting key plates between modules and the corner key plates at the beam ends can effectively improve the initial rotational stiffness of the joint.关键词
