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 ...

What buildings are suitable for steel structure?

What buildings are suitable for steel structure ? Steel Gymnasium Steel structures are widely used in various types of buildings due to their durability, flexibility, and affordability. Some of the buildings that are suitable for steel structure include: Industrial Buildings: Steel structures are commonly used for industrial buildings such as factories, warehouses, and distribution centers due to their large spans and open floor plans. Commercial Buildings: Steel structures can also be used for commercial buildings such as shopping centers, supermarkets, and office buildings, as they can accommodate large open spaces and provide flexibility for future modifications. Residential Buildings: Steel structures are increasingly being used for residential buildings such as apartments and condominiums due to their strength, durability, and ability to withstand natural disasters. Agricultural Buildings: Steel structures are well-suited for agricultural buildings such as barns, silos, and storag...

What is pipe truss?

  What is pipe truss? pipe truss pipe truss Pipe truss structures are a type of steel structure that is used in a variety of applications. Pipe trusses are composed of steel pipes that are connected together to form a rigid frame. The pipes are connected using welds, bolts, or rivets, and the frame is then covered with a protective coating to protect it from the elements. Pipe trusses are often used in the construction of bridges, buildings, and other large structures. Pipe trusses are strong and durable, making them an ideal choice for many applications. They are also highly resistant to fire, corrosion, and extreme weather conditions, making them an ideal choice for many applications. Pipe trusses are also easy to assemble and disassemble, making them ideal for projects that require frequent changes or modifications. Pipe trusses are also highly customizable. Steel pipes can be cut, bent, and shaped to fit any design or application. Pipe trusses can also be painted or coated to ...

The difference between truss and space frame

图片
  The difference between truss and   space  frame : truss roof space frame 1. Truss do not have ball joints, they are in the form of intersecting lines, i.e. the fittings are welded to each other. 2. Space   frames have ball nodes. There are hollow welded balls and solid bolted balls. 3. T russes are generally directly intersecting.

  What Are The Surface Treatments Available For The Space Frame Material? 👉Material of space   frame: ordinary carbon steel, stainless steel, composite stainless steel, reinforced plastic. 👉In addition to painting, the surface also has the following special surface treatments: zinc spraying, aluminum spraying, powder spraying (plastic spraying), fluorocarbon spraying, etc.

Features of truss

图片
  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.

BOLT BALL

图片
 BOLT BALL Space frame structure is a kind of structure connected by the node of bolt ball , so the bolt ball is the key component of the structure. In GB standard. the bolt ball is made of 45# steel with the diameter of 100mm to 300mm. Normally there are 3-12 holes in the bolt ball and each axial line of the bolt hole is through the center of the ball.
