Different types of girders include I-beams, box girders, and truss girders. Stressing is done to transfer loads to the concrete. Grouting is used to fill gaps and provide additional support.

• Types of girders: I-beams, box girders, truss girders

• Stressing process transfers loads to the concrete

• Grouting process fills gaps and provides additional support

Pile foundation is a type of deep foundation used to transfer loads from a structure to a stronger layer of soil or rock below.

• Pile foundations are used when shallow foundations are not feasible due to weak soil conditions or high loads.

• Piles are long, slender columns made of materials like concrete, steel, or timber.

• Types of pile foundations include driven piles, bored piles, and screw piles.

• Pile foundations can be en...read more

The grade of concrete refers to its strength and durability.

• The grade of concrete is determined by its compressive strength.

• It is denoted by a number followed by the letter 'M' (e.g., M20, M30).

• The number represents the compressive strength in megapascals (MPa) at 28 days.

• Higher grade concrete has higher strength and is used for heavy-duty structures.

• Lower grade concrete is suitable for non-structural elements like sid...read more

To check the shuttering of a pier, inspect the formwork for proper alignment, stability, and quality of materials.

• Inspect the formwork for any misalignment or gaps

• Check the stability of the formwork by ensuring it is properly braced and supported

• Verify the quality of materials used for the formwork, such as the strength of the timber or steel

• Ensure that the formwork is properly secured to prevent any movement during co...read more

Lap length is the length of overlap between two reinforcing bars, while development length is the length of bar required to transfer full load from bar to concrete.

• Lap length is used in splicing of reinforcement bars, while development length is used to ensure proper bond between reinforcement bar and concrete.

• Lap length is typically 50 times the diameter of the bar, while development length is calculated based on fact...read more

The grade of steel used in bridge construction depends on various factors such as the design requirements, load capacity, and environmental conditions.

• The grade of steel is determined based on its strength, ductility, and resistance to corrosion.

• Common grades of steel used in bridge construction include ASTM A709, ASTM A588, and ASTM A572.

• For example, ASTM A709 Grade 50 steel is commonly used for bridge girders and AST...read more
