摘要

摘要: 为进一步探索免焊型高强钢柱的连接形式及其受力性能，在试验基础上对螺栓连接高强角钢拼接柱的抗压性能进行了数值模拟和理论分析。首先，利用ABAQUS对试件进行有限元建模和正确性验证。然后，扩展了48个有限元模型，研究了角钢腹板高厚比、角钢翼缘宽厚比、中间板厚度、中间板宽度对高强角钢拼接柱抗压性能的影响。最后，评估了国内外现有设计规范的适用性，并对较为保守的设计规范进行了修正。结果表明：4个参数均对高强角钢拼接柱承载力有积极影响，其中角钢翼缘宽厚比是影响承载力的主要参数，长细比越小的试件受翼缘宽厚比的影响越大。修正后的设计公式预测高强角钢拼接柱的承载力更为准确。

Abstract: In order to further explore the connection form and mechanical properties of non-welded high-strength steel columns， numerical simulations and theoretical analysis of the compressive performance of bolted high-strength angle steel spliced columns were carried out based on experimental studies. First， finite element modeling and verification of the specimens were performed using ABAQUS. Then， 48 extended models were established to investigate the effects of the height-thickness ratio of the angle steel web， the width-thickness ratio of the angle steel flange， and the thickness of the middle plate on the compressive performance of high-strength angle steel spliced columns. Finally， the applicability of existing Chinese and international design specifications was evaluated， and modifications were proposed for the more conservative design specifications. The results showed that all four parameters had a positive effect on the bearing capacity of high-strength angle steel spliced columns， with the width-thickness ratio of the angle steel flange being the most influential parameter. The smaller the slenderness ratio， the greater the influence of the width-thickness ratio of the flange. The modified design formula provided a more accurate prediction of the bearing capacity of high-strength angle steel spliced columns.
