What are the advantages of Prestressed Concrete over Conventional Reinforced Concrete?

Anchor Block for Post Tensioning

What are the advantages of Prestressed Concrete over Conventional Reinforced Concrete. The prestressing of concrete has several advantages as compared to traditional reinforced concrete without prestressing. A fully prestressed concrete member is usually subjected to compression during service life. This rectifies several deficiencies of concrete. Serviceability and Strength Reduces occurrence of cracks . Freezing & … Read more What are the advantages of Prestressed Concrete over Conventional Reinforced Concrete?

What is Resilience and Modulus of Resilience?

Resilience and Modulus of Resilience

Resilience and Modulus of Resilience Resilience. Resilience is the total elastic strain energy which can be stored in the given volume of metal and can be released after unloading. it is also equal to area under load deflection curve within elastic limit. Modulus of Resilience is defined as elastic strain energy per unit volume and … Read more What is Resilience and Modulus of Resilience?

Toughness and Impact Strength of Metals

Charpy test

Toughness and Impact Strength of Metals Toughness is the resistance to the impact loading against fracture. If a metals is tough, then it has the ability to store large strain energy before failure, deflection curve up to fracture stage. Modulus of Toughness It is the total strain energy per unit volume upto fracture stage. it … Read more Toughness and Impact Strength of Metals

What is Proof Stress?

Proof Stress and Proof Resilience

Proof Stress In some ductile materials such as Aluminium, Copper, Mild Steel, the yield point cannot be clearly defined during tension test, therefore yield stress is Unknown. For such metals design stress called PROOF stress is calculated using offset method. An offset of strain equal to given permissible plastic strain, eg at 0.2% for Al, … Read more What is Proof Stress?

6 Reasons why Mild Steel is most commonly used metal in Civil Engineering for Reinforced Concrete

High Tensile Deformed Bar

Why Mild Steel is most commonly used metal in Civil Engineering for Reinforced Concrete? Even though there are lots of metals (like Aluminium, Cast iron ) available for reinforcing concrete, Mild Steel is the most widely used reinforcing material in reinforced concrete. Following are the major reasons behind this. It is highly ductile. The Young’s … Read more 6 Reasons why Mild Steel is most commonly used metal in Civil Engineering for Reinforced Concrete

Failure modes in beams | Types of Failure in Reinforced Concrete Beams

Development Of Cracks in Beams

Failure Modes in beams There are two common types of failure in slender, non Prestressed flexural elements that carry the load in one direction only are Compression failure of the Compressive Chord “ductile flexural failure”:  After yielding of the reinforcement, if no redistribution of forces is possible, the deformations of the beam become important while … Read more Failure modes in beams | Types of Failure in Reinforced Concrete Beams
