膜结构充电桩车棚结构的性能分析!
来源:http://www.sdcscp.com/ 发布时间:2021-09-08
众所周知,膜结构充电桩车棚结构的实际功能都是由整体上来实现的。从整体上分析该结构,其结构的刚性构件与柔性构件相互协同工作,其整体性较传统结构越为显明,张拉膜结构越高的整体性以及各结构构件越强的协同工作特性也是它较传统结构的一大优点所在。
As we all know, the actual functions of membrane charging pile shed structure are realized by the whole. From the overall analysis of the structure, the rigid members and flexible members of the structure work together, and its integrity is more obvious than that of the traditional structure. The higher the integrity of the tensile membrane structure and the stronger cooperative working characteristics of each structural member are also one of its advantages over the traditional structure.
荷载作用于膜屋面传递到拉索和网壳,网壳传递到周围柱列,其中一部分传递到柱列的各个基础,而膜面、网壳、柱列上面所受到的大部分荷载则是经过拉索传到主桁架拱终传到拱的厚大基础上。
The load acts on the membrane roof and is transmitted to the cable and reticulated shell, and the reticulated shell is transmitted to the surrounding column columns, part of which is transmitted to each foundation of the column columns, while most of the load on the membrane surface, reticulated shell and column columns is transmitted to the thick foundation of the main truss arch through the cable and finally to the arch.

结构的传力途径相当明确,而在整个传力过程中,膜材和拉索中存在的预应力不但对平衡外部荷载有很大的贡献,而且成为膜结构充电桩车棚连接结构各构件形成统—协同工作整体的较强内在因素,大大加强结构的整体性,也使各构件材料的受力性得到充分的发挥。
The force transmission path of the structure is quite clear. In the whole force transmission process, the prestress existing in the membrane material and cable not only makes a great contribution to the balance of external load, but also becomes a strong internal factor for the connection of various components of the membrane structure charging pile shed structure to form a system cooperative whole, which greatly strengthens the integrity of the structure, It also gives full play to the stress of each component material.
在结构整体分析中所面临的问题如:①刚性构件、柔性构件能否理想地协同工作,又对柔性构件的预应力分布有何影响;②膜材中的预应力应怎样控制而使得网壳与周边柱列受力合理,而当它们反过来作用于膜材时,较多的影响因素相互制约又该如何把握;③能否真的实现整个体系的自平衡等,这些在设计分析的过程中面临的问题,都较好地培养了在实际教学与实际的工作中发现的问题解决问题的能力。
The problems faced in the overall structural analysis are as follows: ① whether the rigid members and flexible members can work together ideally, and what impact does it have on the prestress distribution of flexible members; ② How to control the prestress in the membrane material to make the stress of the reticulated shell and the surrounding columns reasonable, and how to grasp when they act on the membrane material in turn, many influencing factors restrict each other; ③ Whether the self balance of the whole system can be really realized, these problems faced in the process of design and analysis have better cultivated the ability to solve the problems found in practical teaching and practical work.
对于结构整体性分析在结构设计中是相当重要的,在该膜结构充电桩车棚的设计制作中较好地训练了对结构整体分析的能力与意识,也培养了由概念设计中理解与实现结构设计的能力。
Structural integrity analysis is very important in structural design. In the design and manufacture of the membrane structure charging pile shed, the ability and consciousness of structural integrity analysis are well trained, and the ability to understand and realize structural design from conceptual design is also cultivated.
