Design Principle of Fish Belly Beam

 

Fish Belly Beam


The design principle of the fish-belly beam is mainly based on its unique structural form, which has a beam with a large middle part of the cross-section and then gradually decreases towards the ends, similar to the shape of a fish's belly. The main purpose of this design is to increase the bending strength of the beam while saving material.

Specific applications of fish-belly girders include structures consisting of steel strands and steel trusses with spans that can reach over 60m. By applying prestressing force to the steel strands, a large reaction force can be generated to the supporting bars of the fish-belly girders, which significantly reduces the bending moment acting on the purlins of the fish-belly girders and improves the bending stiffness of the girders. In addition, the prestressed fish-belly girders can be connected together with angle braces or buttress girders through specialized nodes to form a support system for deep foundation pits.

Several cutting methods of steel structure space frame

图片
  Steel st ructure space frame s are now widely used, such as galvanized steel warehouse , glass dome building , airport hangar ,steel structure warehouses, hall roofs, gymnasiums, etc. The builder will cut, produce, and process according to the customer's requirements. There are many ways to cut steel structure space frame s, which will help you to have more choices of cutting. Then, the space frame   manufacturers below will give us a detailed description of several common cutting methods. The cutting methods of the steel structure space frame   are as follows: 1. Flame cutting by CNC machine tools: that is to say, use oxygen cylinders to oxidize and melt steel at a high temperature continuously. At present, natural gas is generally available, which is relatively reliable. 2. Waterjet cutting machine: Generally, high-pressure flowing water is used for cutting, and the accuracy is very high. It is often cut in some very thin, medium-thick steel that requires precision m...

What are the advantages of steel over traditional concrete?

  steel warehouse Steel structures offer several advantages over traditional concrete structures that cover a wide range of areas, including speed of construction, flexibility, sustainability, and more. Here are some common advantages of steel construction:   Lightweight and High Strength: Steel is a lightweight and strong building material. Compared to concrete, the use of steel reduces the dead weight of the building, which in turn reduces the load on the foundation and lowers the overall weight of the building.   Fast construction: Steel structures can be prefabricated in a factory and then simply assembled on site. In contrast, traditional concrete structures typically require more on-site pouring and maintenance time. As a result, steel structures are often faster to construct, helping to shorten project duration.   Design Flexibility: Steel structures are strong and malleable and can support large spans and diverse building designs. This gives designers more f...

  With the continuous improvement of socialist productivity, various industries are developing in the direction of rapid development, so is the steel space frame engineering industry. Due to the Therefore, we should attach great importance to the  space frame cost  management, because the project involves many aspects and fields, and only through reasonable project space frame cost management, can we ensure the quality of the last step of the project. Therefore, we should fully realize that dynamic management and control of project cost is a very important work content and link. In order to improve the quality level of steel grid engineering, dynamic management and control of project cost should be further strengthened. Optimizing the investment process is the most critical link in the steel space frame. the same time, it is also a very important aspect in the process of space frame construction cost management. Therefore, active and effective measures should be take...
