摘要

为研究不同环境温度下钢管约束混凝土柱的抗震性能，开展了9根不同温度工况下的钢管约束混凝土柱拟静力试验，分析各试件在不同温度下的试验现象及破坏形态，揭示环境温度对钢管约束混凝土柱抗震性能的影响机理。针对现行钢管约束混凝土骨架曲线模型计算方法中未考虑环境影响的不足，基于试验和有限元计算结果，提出了考虑环境温度影响的钢管约束混凝土理论骨架曲线特征点温度修正计算公式。结果表明：环境温度变化引起的钢管约束混凝土材料变异和温度附加套箍效应对试件水平承载力和延性影响显著，环境高温（60℃）会使核心混凝土强度降低，且在钢-混凝土界面易发生脱粘脱空，导致试件承载力和延性分别下降9.4％、12.2％；低温（-40℃）工况下，由于核心混凝土强度提高，同时外壁钢管对核心混凝土的约束作用加强，使试件承载力提升18.7％，但其延性最大降低47.2％，对抗震产生不利影响；本文所提考虑环境温度影响的钢管约束混凝土理论骨架曲线具有较好的可靠性和精度，可为高寒大温差地区该类型结构的抗震设计提供必要理论依据。

Abstract

To study the seismic performance of steel tube confined concrete columns under different ambient temperatures, nine quasi-static tests of steel tube confined concrete columns under different temperature conditions were conducted. The test phenomena and failure modes of each specimen under different temperatures were analyzed, revealing the mechanism of the influence of ambient temperature on the seismic performance of steel tube confined concrete columns. In view of the lack of consideration of environmental effects in the current calculation method for the theoretical skeleton curve model of steel tube confined concrete, based on experimental and finite element calculation results, a temperature correction formula for the characteristic points of the theoretical skeleton curve of steel tube confined concrete considering the influence of environmental temperature is proposed. The results show that the material variation of steel tube confined concrete caused by the change of ambient temperature and the Temperature-induced additional constraint effect have a significant effect on the horizontal bearing capacity and ductility of the specimens. Under the condition of high temperature (60 °C), the bearing capacity and ductility of the specimens decrease by 9.4 % and 12.2 % respectively due to the decrease of the strength of the core concrete and the debonding of the steel-concrete interface. Under low-temperature (-40℃) condition, due to the increase in the strength of the core concrete, and at the same time, the outer wall steel pipe strengthens the restraining effect on the core concrete, so that the specimen bearing capacity increases by 18.7%, but its ductility decreases by a maximum of 47.2%, which has a negative impact on seismic resistance. The theoretical skeleton curve of steel tube confined concrete considering the influence of ambient temperature proposed in this paper has good reliability and accuracy, which can provide the necessary basis for the design of steel tube confined concrete in high cold and large temperature difference areas.
