Pile heads are removed to allow for further construction or to ensure proper load transfer to the foundation.

• To prepare for further construction on top of the piles

• To ensure proper load transfer to the foundation

• To facilitate the installation of pile caps or beams

There are four deductions of 90 degree angles.

• A 90 degree angle is formed when two lines intersect at a right angle.

• In a square, all four angles are 90 degrees.

• In a rectangle, opposite angles are 90 degrees.

• In a right triangle, one angle is always 90 degrees.

Static load test is used to measure the load capacity of a structure under a constant load, while dynamic load test is used to measure the response of a structure to varying loads.

• Static load test involves applying a constant load to a structure and measuring its response over time.

• Dynamic load test involves applying varying loads to a structure to simulate real-life conditions.

• Static load test helps determine the maxi...read more

The number of tolerance of pile load test depends on the specific project requirements and standards.

• The number of tolerance of pile load test can vary based on the project specifications and standards.

• Typically, a tolerance of +/- 5% to +/- 10% is considered acceptable for pile load tests.

• Some projects may have more stringent tolerance requirements depending on the criticality of the structure.

• It is important to refer...read more

There are several types of formwork used in construction.

• Formwork for columns

• Formwork for beams

• Formwork for slabs

• Formwork for walls

• Formwork for stairs

• Tunnel formwork

• Bridge formwork

Tension force occurs on the bottom of the cantilever beam.

• Tension force is caused by the bending moment in the beam.

• The bottom of the beam is in tension while the top is in compression.

• The location of maximum tension force depends on the loading and support conditions.

• Examples of cantilever beams include diving boards and balconies.

Hydration process is the chemical reaction between cement and water which results in the hardening of concrete.

• Hydration process starts as soon as water is added to cement.

• The reaction produces heat and causes the mixture to harden and gain strength.

• The process continues for weeks and even months, resulting in a stronger and more durable concrete.

• The amount of water used in the mixture affects the hydration process and...read more

Concrete strength depends on various factors.

• Water-cement ratio

• Type and quality of cement

• Aggregate size and shape

• Curing conditions

• Mix design

• Age of concrete

• Temperature and humidity

• Presence of admixtures

Water is added to concrete mixer to make the mixture more workable and to achieve the desired consistency.

• Water is added to hydrate the cement and activate the chemical reaction that causes it to harden

• The amount of water added affects the strength and durability of the concrete

• Too much water can weaken the concrete and cause cracking

• The water should be added gradually and mixed thoroughly to ensure even distribution

• Ot...read more

BMD stands for Bending Moment Diagram and SFD stands for Shear Force Diagram in civil engineering.

• BMD shows the variation of bending moment along the length of a beam.

• SFD shows the variation of shear force along the length of a beam.

• Both diagrams are essential for analyzing the internal forces in a structure.

• BMD and SFD are commonly used in structural analysis and design.

• Understanding BMD and SFD helps in determining t
