摘要
为对装配式贝雷梁进行精细化模拟与分析,基于贝雷销轴的精细化接触模拟方法,建立贝雷梁实体有限元模型,验证线性状态下数值模拟方法的可行性。通过不同侧向支撑间距下的稳定分析,研究结构的受力性能。结果表明:销轴结构具有极大的安全储备;线性状态下贝雷梁的有限元模拟分析结果与试验值较贴合,表明提出的贝雷梁精细化数值模拟方法是可行的;非线性时贝雷梁的侧向支撑间距对结构的失稳模式起决定性作用。
In order to carry out fine simulation and analysis of prefabricated Bailey beam,based on the fine contact simulation method of Bailey pin,a solid finite element model of Bailey beam is established,and the feasibility of numerical simulation method under linear state is verified.Through the stability analysis under different lateral support spacing,the mechanical performance of the structure is researched.The results show that the pin structure has great safety reserve.The results of finite element simulation of Bailey beam in linear state are in good agreement with the experimental data,which indicates that the refined numerical simulation method of Bailey beam is feasible.Considering the nonlinearity,the lateral support spacing of Bailey beam plays a decisive role in the instability mode of the structure.
