There we talk about beam-column connection in detail and what it uses Connection type of beam to metal column (by stiffness) Connect the beam frame to the metal column The connection of the beam frame to the metal column is completely rigid and the beam is not allowed to move in any X, Y and Z directions. They transmit moments or anchors, for which beam connection plates must be installed. The full grip is usually provided by the under-head sheet as the seat and scarf (tow head) and, if necessary, by the sheet or body horns (Tadley sheet). These connections can be made as flanges or by splice plates (patches) in the form of bolts and nuts or directly by welding. Connect the beam frame to the metal column Hinged connection to the seat angle Articulations have two motion-limiting directions, X and Y. They do not transmit moments or anchorage, so there are no clamped connection plates in this connection, only the top and bottom of the connection are welded to the post. 
The articulated joint will have a nashmin (seat plate with sitting corners, with or without lathi), and it will have a John (Todli) sheet or corner if desired. In a bolted connection, the joint connection can only consist of one web. In this connection to a column or support beam, it is important to control the welding of the sheet metal, because if its welding is defective, the connection will be very fragile and dangerous. To learn more about the types of connections in metal framing, be sure to visit the article "Types of Connections in Metal or Steel Framing." Beam-column connection type according to geometry frame joint in this connection, the side beams are connected to the wings of the column by means of a pair of angle steels, either by screws or by welding. The main force transmitted by the frame connection is the shear force of the beam, which is transmitted from the web of the beam to the column through the angle. This joint is one of the common and standard types of steel joints and is considered a simple joint in terms of stiffness and resistance. Simple socket connection (unreinforced) In a simple unreinforced connection, the beam rests on a flexible seat (usually at an angle). In these connections, an apex angle is always installed to provide lateral restraint of the beam compression wing. In a simple seat connection, the support reaction force of the beam is transmitted to the wings of the column through the seat angle. Corner legs are attached to beams and column wings by welding or screws. This connection also falls under the category of simple connections in terms of rigidity and resistance. 
Due to the high flexibility of the seat angle, this type of connection cannot transmit excessive support reaction forces. Reinforced beam-column connection in a stiffener connection, the beam is placed on the stiffener. This type of seat consists of two orthogonal plates with a T-shaped section. Bottom stiffeners are available as polygons or triangles. The sitting angle and the reinforcing angle can be used to strengthen the sitting connection. These types of connections are not used to transmit bending moments, they are used to transmit support reaction forces, but the screws or welds connecting the corners to the column wings are also affected by the bending moment due to the offset from the load center. These types of connections are also classified as simple connections in terms of stiffness and resistance. When the reaction force of the support is large, it is recommended to use the reinforcement connection. Seated joints, despite being classified as simple joints, have higher stiffness and strength than corner joints. In other words, the amount of bending moment that the frame connection can transmit is higher. In any case, such a connection can be classified as a semi-rigid connection. Connect beams to columns with corners, upper and lower plates in this type of connection, the flanges of the beams are connected to the flanges of the columns by upper and lower plates, and the webs of the beams are connected by a pair of corners. The connection of plates and corners to beams and columns can be by welding or screwing. Instead of corners in this type of connection, thin plates can be used to connect the beams to the wings of the columns. In addition to transferring shear forces in the beam, this connection also transfers the bending moment from the beam to the column. Depending on the stiffness of the connecting plate and beam, the angle of rotation between the beam and column is kept as constant as possible. Therefore, the above form of connection is considered in terms of stiffness and resistance in the classification of rigid connections. Connection via shielding profile in relation to the shielding profile, the beam wings are connected to the shielding legs and the column wings are screwed to the shielding wings. Sometimes, in this type of connection, the beam is attached to the wing of the column with screws. 
The shield connection is also capable of transmitting shear forces and a proportional bending moment and depending on the size and dimensions of the shield, angle, screws, and stiffness of the beam, it can behave as a semi-rigid to rigid connection. Connection by end plate welded to beam (flange connection) In the flange connection, a thin plate with a width almost equal to the width of the column wing and a length of about twice the beam height is completely welded to the beam and connected to the column wing by screws. This type of connection can also transfer shear and bending moments from beams to columns and is considered in the classification of rigid connections. The welding connection between the beam and the plate adopts full penetration welding, and the connection between the beam and the plate adopts penetration welding or fillet welding.
- What is Its Use of Beam and Column?
In fact, beams are one of the basic and very important elements in construction. the building's beams oversee absorbing tension and bending strain. Note the application of steel beams in construction: The use of steel beams in steel structure frames in building construction, any of the above-mentioned 4 kinds of steel beams can be used in the steel structure frame to transform the building according to the plan, design, and calculation of the building designer. Application of Iron Beams at the Bottom of Columns Reinforcing bars are available for column base plates and steel plates of different thicknesses. Use of iron beams in columns Wide spars with an almost square cross-section can be used as columns in the structure. Columns transmit vertical and horizontal wind forces to the foundation of the building. There are 3 ways that columns are used in metal frame buildings: The columns in the middle if we think of them as the center of a square, transmit the load of the whole square. A jamb carrying half a square load. 
Corner post carrying a quarter square load. Using Iron Beams (Shahtir) in Main Beams The horizontal members of a steel structure are called beams, and another use of iron beams in building construction is as main beams or girders. The main beam is connected to the column by shear or simple connection. Using iron beams for center beams or side beams are intermediate members or columns in construction whereas trabeculae are used as intermediate beams. The main task of the secondary beam is to connect the primary beam indirectly to the column and transfer the load to the primary beam. The use of iron beams in coiled beams Iron beams are also used as coil beams in building construction. The coil beam is also a horizontal beam, which relates to the roof truss as two beams in the roof and transfers the load of the main beam to the building column. Application of Iron Beams in Narrow Chrome Iron Beams These beams are narrower than poles, but they are longer in length, so they are called narrow beams. Application of Iron Beam in Truss Construction They also used iron beams to build trusses. Application of Steel Beams in Bridge Construction The structure consists of a horizontal beam supported at both ends by foundations that carry the weight of the bridge and vehicles. What are the principles of using steel beams in bridge construction? Whether the bridge is designed to be flat, convex, or concave depends on the load-bearing capacity of the structure. These are the foundations of the bridge responsible for carrying this load. If beams are used when building bridges, both compression and tension forces applied to the beams are applied to the beams. 
For this, it is necessary to use strong beams to resist the bending and twisting of the beams due to high loads on the bridge. Trusses are also used to build bridges using beams. In fact, trusses made of steel are used to support the beams and distribute the compression and tension on the beams. You should analyze the stress distribution on the different elements of the bridge to ensure the strength of the bridge. Both ends of beams used in bridge construction must be supported by foundations to increase the bearing capacity of the bridge. Cans are better for torsional loads, but beams are more affordable and simpler to manufacture. Therefore, it is recommended to use beams reinforced with wing plates to build bridges. The span of the bridge will depend on the weight of the beams and the strength of the materials used in construction. The thicker the structure of the bridge, the greater its ability to carry loads. Of course, if the beam is heavy, the bridge may bend. Fortunately, with the advancement of technology, this problem has also improved. Currently, bridges made of iron beams are made of strong, lightweight, and durable materials. Application of its beams in ship and wharf construction to play the role of a logistics center, a terminal needs a relatively solid foundation. Its beams can provide a complete structural frame for this structure. Hash beams have this ability, which is why they are one of the most popular options for building cargo ships. Of course, ordinary beams can also be used to build boat decks. The most common beam sizes and various uses for the dimensions are as follows: Applications for size 12 beams Beam 12 has a weight range of 10.4 to 26.8 kg per meter and is the standard used in production.
This beam is used to build columns, roof coverings, and beams. Applications for size 14 beams This type is the most widely used beam type, with weights ranging from 12.9 to 33.7 kg per meter, depending on the standard used. Beam 14 is produced by almost all factories in the country. Generally, 14-gauge beams are used in the construction of columns, trusses, soles, and beams for roof coverings. Its honeycomb type is also used in bridge construction. 16 beam applications This beam is also widely used and the weight per meter varies from 15.8 to 41.6 kg according to different standards. 16 Iron beams are used in the construction of trusses, horseshoes, roof beams, and honeycomb bridges. Application of iron beams 18 The No. 18 beams are all manufactured according to the three standards of IPE, INP, and IPB, and the weight per meter varies from 18.8 to 49.1 kg. Applications for this type of beam are sizes 14 and 16; however, due to its heavier weight, it is more useful in large and heavy structures. Application of No. 20 Steel Beam The 20-gauge beam is one of the different sizes of beams produced and supplied by all the factories.
