摘要
砖混结构在临近地铁等市政工程存在一定风险,需对结构进行必要的振动评定和分析,从而采取必要的加固措施。通过采集地铁运行的振动数据,基于COMSOL软件的结构力学模块,根据相应材料的本构关系,对某临近地铁的砖混结构建筑进行了实体、梁、壳单元的耦合分析,计算了该砖混结构的振动模态、最大层间位移角和应力。分析表明,该砖混建筑的主结构受力状态完好,振动平稳,在地铁营运过程中是安全可靠的。
The brick-concrete structures have certain risks in municipal projects such as subways, and it is necessary to conduct necessary vibration assessment and analysis of the structure, so as to take necessary reinforcement measures. By collecting the vibration data of subway operation, based on the structural mechanics module of the COMSOL software, according to the constitutive relationship of the corresponding materials, the coupling analysis of the solid, beam and shell elements of a brick-concrete structure near the subway is carried out, and the vibration mode, maximum interstory displacement angle and stress of the brick-concrete structure are calculated. The analysis shows that the main structure of the brick-concrete building is in good condition and has stable vibration, which is safe and reliable during the operation of the subway. The research results have guiding significance for the vibration assessment of masonry structures along subway lines.
