QS codes are used in Quantity Surveying to categorize and organize different items and costs related to a construction project.

• QS codes are alphanumeric codes used to identify specific items or costs in a construction project.

• They help in standardizing the categorization and organization of project data.

• For example, a QS code for 'concrete foundation' could be CF001.

• These codes are often used in cost estimation, budget

Various codes are used in design, such as color codes, HTML codes, CSS codes, and design software codes.

• Color codes are used to specify colors in design, such as #FFFFFF for white.

• HTML codes are used to structure web pages, like

  for heading 1.

• CSS codes are used to style elements on a webpage, such as font-size: 16px;

• Design software codes refer to commands and functions within design tools like Adobe Photoshop or Illus

OMRF and SMRF are two different seismic force-resisting systems used in building construction.

• OMRF stands for Ordinary Moment Resisting Frame and is used for low to moderate seismic zones.

• SMRF stands for Special Moment Resisting Frame and is used for high seismic zones.

• OMRF is designed to resist lateral forces through flexural strength of beams and columns.

• SMRF is designed to resist lateral forces through a combination...read more

Moments are released in trusses at points where the truss is supported by a fixed joint or a roller joint.

• Moments are released to prevent the truss from rotating at the support point.

• Fixed joints do not allow any rotation, so moments are released at those points.

• Roller joints allow rotation in one direction, so moments are released in the perpendicular direction.

• Releasing moments also helps to distribute the load evenl...read more

2-stroke engines have a power stroke every revolution, while 4-stroke engines have a power stroke every other revolution.

• 2-stroke engines are simpler and lighter than 4-stroke engines.

• 2-stroke engines have a higher power-to-weight ratio than 4-stroke engines.

• 4-stroke engines are more fuel-efficient and have a longer lifespan than 2-stroke engines.

• Examples of 2-stroke engines include chainsaws and dirt bikes, while exam...read more

Iron carbon diagram is a graphical representation of the phases of iron-carbon alloys at different temperatures and carbon concentrations.

• It shows the relationship between carbon content, temperature, and the resulting microstructure of steel.

• It is used to determine the properties of steel and to predict its behavior under different conditions.

• It consists of three regions: austenite, ferrite, and cementite.

• The diagram ...read more
