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.
Since container buildings are widely used nowadays,this paper attempts to make a study on the longitudi-nal stiffness of container with holes under external load. Firstly,by applying diaphragm theory,a mechanical analy-sis and stiffness calculation method of container with holes were given,followed by examples to illustrate the calcu-lation process. Then,through nonlinear finite element software of ABAQUS,a finite element model of container was established. Based on the area and aspect ratio of the hole,a parametric analysis was given to obtain the influ-ence law of parameters on the stiffness of container with holes and some suggestions about the design were followed. Finally,five experimental studies of container with holes were conducted,and both the theoretical and finite ele-ment simulation results were compared with experimental data,which were in good agreement. The research result can offer some references not only in the design and construction of container buildings,but also in the description of relevant norms.
