摘要:
为解决海水海砂中氯离子腐蚀问题,选用合理的材料本构关系和有限元建模技术,建立在局压荷载作用下双金属复合管海水海砂混凝土(SSCFBT)短柱的精细化有限元分析模型。首先,利用已有的试验数据验证了模型的可靠性。然后,基于验证后的有限元模型,分析SSCFBT局压短柱在受力过程中的内力分配规律和应力云图。最后,利用有限元模型开展参数分析,研究局压面积比、端板厚度、混凝土强度等参数对SSCFBT局压短柱承载力的影响规律。结果表明:局压面积比和端板厚度是影响SSCFBT局压短柱承载力和变形能力的关键因素。基于参数分析结果,提出适用于SSCFBT短柱的局压承载力简化计算公式。
Abstract:
In order to solve the problem of chloride ion corrosion in seawater and sea sand, a refined finite element analysis model of seawater and sea sand concrete filled bimetallic tube(SSCFBT)stub column under the local compressive load was established by reasonable material constitutive relationship and finite element modeling technology. The reliability of the model was validated using existing experimental data. Based on the verified finite element model, the internal force distribution and stress nephogram during the loading process of SSCFBT local compressive stub columns were analyzed. The parametric analysis was conducted using the finite element model to investigate the influence of parameters such as local compressive area ratio, end plate thick-ness, concrete strength on the load-carrying capacity of SSCFBT local compressive stub columns. The results show that the local compressive area ratio and end plate thickness are the key factors affecting the load-carrying capacity and deformation capacity of SSCFBT local compressive stub columns. Based on the results of the parametric analysis, a simplified calculation formula for the local compressive load-carrying capacity of SSCFBT stub columns is proposed.
