Why do we splice columns?
Multi-Storey structures generally require that the columns be ‘spliced’ in order to extend their length for the full height of the structure. Splices may be either bolted or welded and its always assumed that welded splices are ‘shop-welded’ while bolted splices are ‘site-bolted’.
What is splicing in steel structure?
A splice joint is a method of joining two members end to end in woodworking. Splice joints are stronger than unenforced butt joints and have the potential to be stronger than a scarf joint. Splices are therefore most often used when structural elements are required in longer lengths than the available material.
What is splicing in beam?
The Beam Splices mode enables to design and check the load-bearing capacity of erection joints between I- beams with high strength bolts or ordinary bolts using plates or end-plates.
Why splicing is provided?
Splicing of column is necessary in the following cases: When the available length of structural steel section is less than the required length of the column. In case of multi-storey buildings, the section of column required for the various storeys may be different.
What is splicing in RCC?
The method used to join the reinforcement bars, so that the force is transferred effectively from one bar to the other is called splicing.
What is splice connection?
A spliced connection is a joint made within the length of a stanchion, a beam or any other structural member. Most splices transfer loads from one structural member to the adjacent part of a similar structural member through either cover plates or end plates.
What is flange splice?
Splice plates are lapped across the joint and bolted to the webs and the flanges of the beam in order to transfer the load. This type of splice is usually referred to as a web-flange splice.
What is Lap length in column?
The lap length is the length provided to overlap two rebars in order to safely transfer load from one bar to another bar and an alternative to this is to provide mechanical couplers.
What is a column splice in structural engineering?
Chapter 9. Column Splices and Bases – Design of Steel Structures [Book] This chapter deals with column splices and column bases. A column splice means the joining of two parts of a column whereas a column base transfers forces and moments at the lower end of a column to a foundation.
Why are bearing plates used to splice columns of different sizes?
The common thing between these is the use of bearing plates since to splice columns of different sizes bearing plates are used as is also the case with column bases. In practice, the splicing of columns is to be done to get the required height.
What is the splicing of steel beams?
The splicing of steel beams The splicing of beams is divided into splicing at the factory and on-site splicing due to different construction conditions. 1) It is best to stagger the flange and web positions to avoid the concentration of welds.
What is l/3 splice?
L/3 a point where the legth from both ends of support is eqully divided by 3,hence the center of lap splice to be considered.However,in vertical Column bars in several pieces per Column,a staggered placement sequence is adopted that is L/3 frm base supports and L/3 from supports of succeeding floor in alternate placements.
