Different types of stirrup used in construction,What is 1L (legged), 2L, 3L, 4L, 5L, 6L and 7 legged stirrups,in this topic we know about different types of stirrup used in construction and what is 1L, 2L, 3L, 4L, 5L, 6L and 7 legged stirrups.
Another word stirrups is also known as ring or shear reinforcement. It is closed loop of reinforcements used to hold the main reinforcement in RCC structure like column and beam.
Various shape of stirrup like square stirrup, rectangular stirrup, circular stirrup and diamond stirrup used in column provide lateral support to the main bar against buckling it is used at proper interval to beam and column to prevent them from buckling. Also they protect RCC structure from collapsing during seismic activity like earthquake.
Uses of stirrups:– stirrups is used to resist lateral shear stress and diagonal tension stress in RCC structure and provide stability to the reinforcement of Steel bar.
Let us discuss about different types of stirrup used in construction and what is 1L (legged),2L,3L,4L,5L,6L and 7 legged stirrups.
What are different shape of stirrup used in construction work
Stirrup may be in various shape and size according to design of column and beam. It come in the shape of rectangular square circular and diamond shape that is Rhombus shape of stirrup.
What are uses of stirrup?
Uses of stirrups:– 1 legged and 2 legged stirrups used in lower dimension of column and beam and 3 legged, 4 legged, 5 legged, 6 legged and 7 legged stirrups used in higher dimension of column and beam.
Legged stirrups:- legged stirrup consists of 1 legged (open stirrups), 2 legged (closed) & multi-legged (closed) stirrups. Multi- legged stirrup are 4 legged, 5 legged, 6 legged, 7 legged and 8 legged stirrups.
What is meaning of L in stirrup
L is stand for legged ,1 legged, 2 legged and 3 legged stirrups are used when width of column and beam is less than respective depth and when width of column and beam is greater than depth of then we provide 4 legged stirrups and more legged —
What is 1L (legged) stirrup?
1 legged stirrups:- It is single legged stirrups generally provided in T shaped beam, the single legged stirrups have rarely have been used because they are mostly used when binding only two rods.
What is 2L(legged) stirrup?
2 legged stirrups:- It consist of 2 legged, it is 2 legged stirrup generally provide in lower dimension of beam and column having width is less than respective depth, the common and widely used stirrup is 2 legged stirrups to provide this stirrup minimum number of rod is required.
What is multi L(legged) stirrup
Multi-legged stirrups:- more than 2 legged are known as multi-legged stirrups. For example 3 legged, 4 legged, 5 legged,6 legged and 7 legged stirrups provide in higher dimension of beam and column having wide width.
4 legged stirrups:- It is made of 4 legged, the cross sectional area of 4 legged stirrups is twice of cross sectional area of 2 legged stirrups and hence it can resist greater stress and shear force. If we increase legged in stirrups there is a increase of strength and bear more stress and also requirement of reinforcement is increased.
4 legged stirrups require more quantity of reinforcement and therefore a resist more shear stress and force and they also provide more stability to the top and bottom reinforcement when pouring of concrete.
