As the required moment of resistance increases. we have to increase depth of the beam to counter the bending moment. But if due to reasons such as head room clearance or asthetics purpose. We cannot increase the depth. then we have to provide additional compression steel so as to take that moment. This is known as doubly reinforced beam.
The collar beam in a collar beam roof performs which of the following functions?
For a built-up column with lacing, what percentage of the axial load is considered as the transverse shear force (Vt) that the lacing system must resist?
Which type of wall is designed to resist lateral forces, like wind or earthquakes?
For a column subjected to bending and compression, the maximum slenderness ratio as per IS 800:2007 is:
What is a good practice to follow when mixing concrete in hot weather?
Why must compression reinforcement in a doubly reinforced beam be enclosed by stirrups?
The minimum cement content (kg/cum) for a ship dock (underwater construction) with 40 mm aggregate is prescribed by the Indian Standard as:
In reinforced concrete walls, the ratio of the effective height to thickness is limited by design code to:
According to the limit state theory, and as taken by IS 456, the maximum compressive strain in concrete in axial compression is taken as:
In a non-cellular, non-ribbed, flat slab, the spacing of reinforcing bars shall be limited to a maximum of in times the thickness of the slab, where m is:
