What is the difference Between under reinforced section and over reinforced section?
When the maximum stresses in steel and concrete simultaniously reaches allowable value the section is called balanced section when the %of steel in a section is less than that required for a balanced section it is under reinforced section when the %of steel in a section is more than that required for a balanced section it is over reinforced section
over reinforcement is as per section design I.e Ast1+Ast2>Ast Ast1+Ast2 An under-reinforced beam is one in which the tension capacity of the tensile reinforcement is smaller than the combined compression capacity of the concrete and the compression steel (under-reinforced at tensile face). When the reinforced concrete element is subject to increasing bending moment, the tension steel yields while the concrete does not reach its ultimate failure condition. As the tension steel yields and stretches, an "under-reinforced" concrete also yields in a ductile manner, exhibiting a large deformation and warning before its ultimate failure. In this case the yield stress of the steel governs the design. An over-reinforced beam is one in which the tension capacity of the tension steel is greater than the combined compression capacity of the concrete and the compression steel (over-reinforced at tensile face). So the "over-reinforced concrete" beam fails by crushing of the compressive-zone concrete and before the tension zone steel yields, which does not provide any warning before failure as the failure is instantaneous.
What else can I help you with?
What is an under reinforced beam?
Under reinforced is that in which provided steel ratio is less than balanced steel ratio. Concrete beams are designed as under reinforced beams. The reason is that the failure start by yielding of steel instead of crushing of concrete. Mian Yaqoob
What are the difference between lintels and beams?
A lintel is over a window or door and a beam is usually under the structure of the building, either the roof or the floor.
What is the plastic section modulus of steel section?
section modulus of any section is the ratio of the moment of inertia to the distance of extreem fibre from the neutral axis. plastic section modulus is the section modulus when the cross section is subjected to loading such that the whole section is under yield load. numerically it is equal to the pdoduct of the half the cross section area and the distance of center of gravity of tension and compression area from neutral axis
Do you need to reinforce the floor of a raft foundation?
If the raft foundation is subject to a uniform load (Water & oil Tanks ..etc) u may not be required to reinforce the floor, only a plain concrete or even well compacted earth is sufficient provided it 'll transfere the load safely i.e giving a pressure less than the allowable bearing capacity of the underlying soil. Only peripheral or ring beams of reinforced concrete is required under the tank walls. If the raft is supporting colmns/walls, then it's subject to knife loads & got to be reinforced.
How much Kg per cum for M40 cement will be?
M40 grade of concrete : is recommended in extreme exposure or when very heavy loads are to be carried (like pier of a bridge etc) Under extreme exposure - reinforced M40 grade concrete should have minimum cement = 360 kg/cubm. This can vary from 300 to 360 for exposures from mild to extreme. Plain M40 grade used under mild to extreme exposure has minimum cement content from 220 to 280 kg/cubm Other considerations like admixtures (fly ahs etc) and actual mix design is the best method of arriving at minimum cement contents.
If the neutral axis of a reinforced section is above the critical section what is the section called?
Under Reinforced Section
What is the difference between a heading and a caption?
A heading is like the name of a section. A caption is a description under a picture of what the picture is about.
What is safer over reinforced concrete or under reinforced concrete?
Under-reinforced concrete is generally considered safer than over-reinforced concrete. This is because under-reinforced concrete will fail in a ductile manner, allowing for noticeable deformation and warning signs before catastrophic failure occurs. In contrast, over-reinforced concrete can fail suddenly and brittlely due to excessive steel reinforcement, potentially leading to more dangerous situations. Therefore, under-reinforced designs are preferred for safety in structural applications.

Please explain difference between 34 IPC 149 IPC AND 120B IPC with example?
Section 34 of the Indian Penal Code provides for the liability of a criminal act done by several persons in furtherance of a common intention. Section 149 deals with the liability of members of an unlawful assembly for an offence committed in prosecution of the common object. Section 120B deals with criminal conspiracy, where two or more persons agree to commit an illegal act. For example, if five people plan and execute a robbery together, they may be charged under Section 34 IPC. If a group of people gather to attack someone and one of them kills the victim, all may be charged under Section 149 IPC. And if two persons conspire to commit a robbery, they may be charged under Section 120B IPC.
