摘要:
针对底部混凝土门式刚架结构节点在复杂服役环境下稳定性分析中忽视Q355B钢本构与损伤耦合、且单一荷载工况难以反映金属材料累积损伤效应的问题,从金属功能材料视角出发,构建基于ABAQUS的精细化有限元模型,引入Chaboche混合硬化本构与延性损伤准则描述循环荷载下的滞回特性与韧性断裂行为,并分别开展行车、地震、风荷载及地震+行车振动组合工况的非线性动力时程分析,通过提取节点区应力应变响应、安全系数演化及累积塑性应变等指标定量评估材料损伤进程。结果表明:7度地震下节点最大应力为242 MPa,安全系数下限为1.2;行车荷载下最大应力为258 MPa,最小稳定系数为13.8;60°风向角风荷载下最大应力为247 MPa,各风向变形稳定;多源耦合荷载工况下节点最大应力升至278 MPa,累积塑性应变明显增大。该节点在各单独荷载工况下均满足稳定性设计要求,可为钢混凝土组合结构节点设计中金属功能材料的选型与性能评估提供参考。
Abstract:
To address the issue that stability analyses of joints in bottom-concrete portal frame structures under complex service conditions often neglect the coupling between the constitutive model and damage of Q355B steel,and that single load cases fail to capture the cumulative damage effects in metallic materials, a refined finite element model in ABAQUS was developed from the perspective of metallic functional materials.The Chaboche mixed hardening constitutive model and a ductile damage criterion are incorporated to characterize the hysteretic behavior and ductile fracture behavior under cyclic loading.Nonlinear dynamic time-history analyses are performed for multiple load scenarios,including traffic loading,seismic excitation,wind loading,and combined seismic-plus-traffic vibration.Quantitative assessments of material damage progression are conducted by extracting joint-region stress–strain responses,safety factor evolution, and cumulative plastic strain.The results indicate that under a seismic intensity of 7 degrees,the maximum joint stress is 242 MPa with a lower-bound safety factor of 1.2;under traffic loading,the maximum stress is 258 MPa with a minimum stability coefficient of 13.8;under wind loads at a 60° incidence angle,the maximum stress was 247 MPa,and the deformation remained stable across all wind directions; and under multi-source coupled loading,the maximum joint stress rises to 278 MPa with a notable increase in cumulative plastic strain.This joint satisfies the stability design requirements under all individual load cases,providing a reference for the selection and performance evaluation of metallic functional materials in the joint design of steel-concrete composite structural structures.
