摘要

摘要: 在输电塔结构极限承载力试验研究的基础上,采用ANSYS有限元软件,分析了不同长细比、不同端部约束条件下Q460等边角钢的应力分布、失稳模式、极限承载力等指标。研究表明:破坏模式方面,有限元分析失稳模式与试验现象基本一致;承载力方面,对长细比为30、45的试件,数值分析结果与试验值相差4%左右,对长细比为60的试件,二者相差10%左右,吻合较好。研究结果可为Q460高强角钢的规范制订和工程应用提供合理依据。

Abstract: Based on the ultimate bearing capacity test of transmission tower structure，it was analyzed the Q460 equalley angle of the stress distribution，failure mode and the ultimate bearing capacity of Q460 equal leg angle which had different slenderness ratio and end constraint conditions by finite element software of ANSYS. The research shows that on the failure mode，the finite element analysis of the buckling mode and test phenomenon are basically consistent; on bearing capacity，for the specimens with slenderness ratio of 30 and 45，there is the difference of only 4% between the results of numerical analysis and experimental value. For the specimen of slenderness ratio 60，the difference is 10% and has a good coincidence. The research results provide the reasonable basis for amending the specification and engineering practice of the Q460 high strength angle.
