Crayonflakes Design Interview Questions and Answers

The major bridge uses driven piles as the primary piling methodology.

• Driven piles are commonly used in major bridge construction.

• They are installed by hammering or vibrating the pile into the ground.

• Driven piles provide strong support and are suitable for various soil conditions.

• Examples of driven piles include steel H-piles and concrete piles.

Girder pre stressing system is a method of applying tension to the steel girders to increase their load-carrying capacity.

• Girder pre stressing system involves the use of high-strength steel cables or tendons that are tensioned and anchored to the girder.

• The tension in the cables creates a compressive force in the girder, which increases its load-carrying capacity.

• The maximum applied pressure in girder pre stressing system depends on the strength of the steel cables or tendons...read more

Soil clay or silt can be identified by conducting simple field tests such as the ribbon test, feel test, and sedimentation test.

• Perform a ribbon test by rolling a small amount of soil between your fingers to determine if it forms a ribbon. Clay soil will form a long, flexible ribbon while silt soil will form a short, weak ribbon.

• Conduct a feel test by rubbing a small amount of soil between your fingers to feel the texture. Clay soil will feel sticky and smooth, while silt soi...read more

Performing triaxial test in rock involves applying different levels of stress to a cylindrical rock sample to determine its strength and deformation characteristics.

• Prepare a cylindrical rock sample with smooth parallel ends

• Place the sample in a triaxial cell and apply confining pressure to simulate in-situ stress conditions

• Apply axial load to the sample while measuring the stress and strain at different stages

• Repeat the test with varying confining pressures to determine the ...read more

Dynamic blocks in AutoCAD are customizable and flexible blocks that can be easily modified using parameters and actions.

• Dynamic blocks allow you to create a single block with multiple variations.

• They use parameters to define the geometry and behavior of the block.

• Actions can be added to the block to modify its appearance or behavior based on user input.

• Parameters can be associated with grips, allowing users to easily manipulate the block.

• Dynamic blocks can be used to create d...read more
