What is a shear key in steel structures?

-
图片
 In steel structure engineering , the column base connection serves as the pivotal interface linking the superstructure to the concrete foundation below. It must safely and reliably transmit various loads from the upper structure: vertical pressure , uplift forces , bending moments , and horizontal shear forces . When horizontal shear forces become substantial, the friction alone between the column base plate and the concrete foundation surface proves insufficient to resist them. At this juncture, a critical small component becomes indispensable—the shear key . Shear keys, as the name suggests, are structural steel connection components specifically designed to resist and transmit horizontal shear forces. Essentially, they are short steel members. Installation location: Typically welded or anchored to the base plate of a steel column (or other load-bearing components such as equipment supports ), with its lower end embedded in the concrete foundation or concrete structure cast ...

Why do most of the stadium bleachers use truss structure?

  The reasons for adopting truss structure for stadium grandstand are as follows: truss roof 1. High strength : Joist structure is composed of multiple triangles, which can disperse the load and support the weight, with high strength and stability. 2. Lightweight : truss structure is usually made of lightweight materials, such as steel or aluminum alloy, which is light in weight and easy to transport and install. 3. Good flexibility : Joist structure can be adjusted and changed as needed to suit different sites and usage requirements. 4. Economical and practical : The manufacturing cost of joist structure is relatively low and the maintenance cost is also low, so it is economical and practical. 5. Beautiful and generous : Joist structure has simple and generous appearance and good aesthetics, which meets the aesthetic standard of modern architecture. _________________________________________________________________ Follow me and take you to learn more! 👇👇👇 www.safsteelstructure...

Features of truss

  From the perspective of material layout (or distribution), the truss can be regarded as a latticed beam as a whole, and its overall mechanical performance is similar to that of the beam. In the detail structure, each rod is used to re-direct the force flow (the nodes between the rods are not overlapped, and the bending moment cannot be transferred), and the overall layout is basically consistent with the main stress trace. Each rod is a secondary force rod, which is only subjected to tension and compression Truss, especially space pipe truss, is often made into arch. However, at this time, the arch is not a pure pressure arch, and the whole arch is still dominated by bending. We can also consider it as a curved beam in a certain sense. Of course, arch camber can increase the span capacity, and the role of "axial force" in the "beam" can not be ignored at this time, but in most cases, especially when the rise-span ratio is small, the bending is still the main part.

What is the truss welding method?

-

  truss roof Most of the rods in joist structures are welded at the nodes. Before welding, the webs and chords need to be cut in advance according to the shape of the weld seam of each member to be welded, which requires cutting of the web ends and slotting of the chords. Since the joist structure is intersected by coherent line between the rods and rods, the shape of rod end section is complicated, so in the actual cutting process, two methods of mechanical automatic cutting process and manual cutting process are generally used.

truss roof A truss refers to a lattice structure composed of round rods connected to each other at the ends. Wide range of applications and economical and practical today. Such as exhibition centers, stadiums or some other large public buildings have been used.   In recent years, with the continuous growth of my country's steel production, steel structures, with their own advantages, account for an increasing proportion of buildings, and steel pipe structures have also made great breakthroughs. The biggest advantage of the steel pipe structure is that it can perfectly combine the functional requirements, sensory requirements and economic benefits of people's buildings. The pipe truss structure in the steel pipe structure is favored by people with its unique advantages. ______________________ Whatsapp/Tel:+ 86/13056229023 E-mail:safs121@safsteelstructure.com www.safsteelstructure.com

 What is a truss? truss roof A structure in which rods are connected to each other by hinges at both ends. The truss is composed of straight rods and generally has a plane or space structure with triangular elements. The truss rods mainly bear axial tension or pressure, so that the strength of the material can be fully utilized. When the span is large, the material can be saved compared with the solid web beam, and the self-weight and weight can be reduced. Increase stiffness. __________________________ Whatsapp/Tel:+ 86/13056229023 E-mail:safs121@safsteelstructure.com Website:www.safsteelstructure.com/
