What is the function of stirrup in beam?
Preet Chovatiya
Stirrups are mainly provided for holding the main reinforcement of beam. It prevents the buckling of beam and also protect the RCC structure during seismic activity. Stirrups providing protection against flexural and shear failure as shown in figure.

Jishnu Raj
Passive earth pressure conditions are Minor principle stress becomes equals to vertical stress (Hv). Major principal stress becomes equal to horizontal stress(Hh). Hh = Hv x Tan^2(alpha).
Passive earth pressure conditions are
- Minor principle stress becomes equals to vertical stress (Hv).
- Major principal stress becomes equal to horizontal stress(Hh).
- Hh = Hv x Tan^2(alpha).

Development length: it is the extra embedded length. It is required for the development of bond and transfer the force from steel to concrete and make the structure continuous at junctions like beam and column.
What is the benefit of smaller dia steel instead of larger dia steel in slab and beam?
INDER KUMAR YADAV
There are many benefits of using a large number of small dia bars than a small number of large dia bars. The reasons are as follows. to provide ductility to the structure, i.e. (beam and slab ) which is not available in the concrete. to provide stability to the structure as the bars have rib designRead more
There are many benefits of using a large number of small dia bars than a small number of large dia bars. The reasons are as follows.
and because of these reasons, it is not possible to provide all these factors using a single bar, and therefore we have to provide a small number of large diameter bars.

Kuldeep Singh
Bar bending schedule (BBS) is a comprehensive, detailed list of reinforcement bars to be used in an RCC construction along with their number, location, mark, type, size, lengths, details in correspondence with the drawings. It also includes the timing for the bending of each bar, and that is why it'Read more
Bar bending schedule (BBS) is a comprehensive, detailed list of reinforcement bars to be used in an RCC construction along with their number, location, mark, type, size, lengths, details in correspondence with the drawings. It also includes the timing for the bending of each bar, and that is why it’s called a bending schedule.
Bars are needed to be bent in order to give them the desired reinforcement shape. Stirrups and anchorages are two places where bar bending is compulsory. In addition, when we need to join bars, we might want to bend them on the ends before welding or fastening.
BBS also gives a clear and logical understanding as to how much bars of what sizes will be needed to be procured and bent by what time so that no delay, all procurement is done with minimal transport expenses, and all bending is done with minimal machine and labor costs.

Tips_and_tricks
Steel has a higher modulus of elasticity than a rubber. We know that Young’s modulus is the ratio of stress to the strain. Therefore it is a property of cross-sectional area, length, and applied load. Taking two samples of steel and rubber of the same cross-sectional area and length, if we apply theRead more
Steel has a higher modulus of elasticity than a rubber. We know that Young’s modulus is the ratio of stress to the strain.
Therefore it is a property of cross-sectional area, length, and applied load.
Taking two samples of steel and rubber of the same cross-sectional area and length, if we apply the same load, the following observation can be made:
This implies that the modulus of elasticity of steel is greater than that of rubber.

a Kicker is a 5-15cm advance that is given at the Column/Shear divider Base during the throwing of the section/establishment. It is given to guarantee that the directions of the section/divider are kept up consistently between the chunks and basically all through the structure. Casting of slab/ founRead more
a Kicker is a 5-15cm advance that is given at the Column/Shear divider Base during the throwing of the section/establishment. It is given to guarantee that the directions of the section/divider are kept up consistently between the chunks and basically all through the structure.
See lessCasting of slab/ foundation, the covering for the segment can be fixed legitimately on the kicker to ensure column location and base alignment is precise.
Its job is to keep away uneven steel cover and Column/wall alignment issues, which are practically difficult to correct once the concrete is cast and can be effortlessly distinguished/redressed by giving a kicker.
An inappropriate practice related to the arrangement of the kicker is that a few contractual workers give a kicker after casting a slab, which includes an extra undesirable Construction columns near the base where the shear is maximum and hence is not advised.
What is the different between development length and anchor length in beam and column?
INDER KUMAR YADAV
development length is the length that is needed to insert in the concrete so that can easily resist the force that is applied whereas anchorage length is the length of bar which is considered to be available when it is bended by some angle and it is provided at the support similarly, the developmentRead more
development length is the length that is needed to insert in the concrete so that can easily resist the force that is applied
whereas
anchorage length is the length of bar which is considered to be available when it is bended by some angle and it is provided at the support
similarly, the development length in the column will be the same as that of beam
from the below image you can understand what I m saying about the development length and anchorage length of beam and column
