内配圆钢管的圆钢管混凝土构件耐撞性能分析
|
摘要
内配圆钢管的圆钢管混凝土是一种新型复合形式的组合构件,由圆钢管混凝土内部配置同心位置的圆管,并在内部圆管的内外两侧均浇筑混凝土而形成的构件。基于有限元软件ABAQUS对内配圆钢管的圆钢管混凝土构件在低速横向撞击作用下的耐撞性能进行了数值模拟,数值结果与其他研究者完成的钢管混凝土、中空夹层钢管混凝土试件的撞击试验数据进行了对比,验证了模型的正确性。采用该模型分析了此类组合构件在横向撞击作用下的动力响应全过程及其典型破坏模态,对影响其耐撞性能的主要影响参数进行了分析,初步得出了各主要影响参数对此类组合构件耐撞性能的影响。参数分析结果表明,提高外钢管的强度及含钢率可以有效地改善该构件的耐撞性能,而混凝土强度的变化对构件耐撞性能的影响很小;增强构件两端的支座约束,可以增强构件的耐撞性能;构件的内外径之比为0.6～0.8时,构件具有较好的耐撞性能。
A circular concrete-filled steel tubular(CFST) member with inner circular steel tube is a new type of combination one in a composite form. It means that a smaller circular steel tube is placed in a larger one with the same geometric axis, and concrete is filled in the inner steel tube and the space between the two tubes. A finite element(FE) model was developed using the software ABAQUS to simulate anti-impact performance of the circular CFST member with inner circular steel tube under low velocity transverse impact. The numerical simulation results were compared with other researchers' test results for CFST members and concrete-filled double skin tubular(CFDST) members, respectively to verify the correctness of the FE model. The FE model was used to analyze the whole process of dynamic response and typical failure modes for this type of combination members under transverse impacting load. The main parameters affecting their anti-impact performance were analyzed. Parametric analysis results showed that increase in strength and steel ratio of outer steel tube can effectively improve the anti-impact performance of this type of combination members while concrete strength has a little effect on their anti-impact performance; strengthened constraints at their two ends can also improve their anti-impact performance; when their inner tube to outer one diameter ratio is 0.6～0.8, they have a better anti-impact performance.
