【摘要】：针对目前广泛使用的集装箱房屋,研究了开洞集装箱在外荷载作用下的纵向刚度.首先,利用蒙皮理论对其进行了力学分析,初步得出了开洞箱体刚度的计算方法,并通过算例阐述了具体的计算过程.然后,利用非线性有限元软件ABAQUS对其建立了有限元模型,并进行了基于开洞面积和洞口高长比的参数分析,得出了各参数对开洞箱体刚度的影响规律,并给出了相应的设计建议.最后,进行了5种开洞箱体刚度的试验研究,并将理论分析和有限元模拟的结果与试验数据进行了对比验证,吻合良好.本研究不仅可为目前广泛使用的集装箱房屋提供设计和施工参考,更可为相应的规范编制提供借鉴.
[Abstract]:The longitudinal stiffness of the open-hole container under external load is studied for the widely used container buildings. Firstly, the mechanical analysis is carried out by using the skin theory, and the calculation method of the stiffness of the opening box is preliminarily obtained, and the concrete calculation process is explained by an example. Then, the finite element model is established by using the nonlinear finite element software ABAQUS, and the parameter analysis based on the opening area and the ratio of height to length of the hole is carried out, and the influence of each parameter on the stiffness of the opening box is obtained. The corresponding design suggestions are also given. Finally, the stiffness of five kinds of open box is tested, and the results of theoretical analysis and finite element simulation are compared with the experimental data, which are in good agreement with each other. This study can not only provide a reference for the design and construction of the widely used container houses, but also provide reference for the corresponding specifications.
