VSB Vasttram Interview Questions and Answers

An ILD for moment and shear at supports of a simply supported beam is required.

• Draw a horizontal line representing the beam.

• Mark the supports at either end of the line.

• Draw vertical lines at the supports to represent the reactions.

• Draw arrows to represent the direction and magnitude of the shear forces at each support.

• Draw bending moment diagrams between the supports to represent the moment at each point.

• Label the diagrams with units and values.

• Ensure the diagrams are neat an...read more

Strength is the ability to withstand stress without deformation, while stiffness is the ability to resist deformation under stress.

• Strength is a measure of how much force a material can withstand before breaking or deforming.

• Stiffness is a measure of how much a material resists deformation under stress.

• Strength is related to the maximum stress a material can handle, while stiffness is related to the slope of the stress-strain curve.

• For example, steel is strong and stiff, whil...read more

An Influence Line Diagram shows the variation of a response function at a specific point due to a unit load moving along the structure.

• It is a graphical representation of the effect of a unit load on a structure.

• It helps in determining the maximum and minimum values of a response function at a specific point.

• It is used in designing and analyzing structures such as bridges and trusses.

• It is also used in determining the critical locations for placing sensors for structural heal...read more

India has 4 seismic zones based on the intensity of earthquakes.

• India is divided into 4 seismic zones - Zone 2, 3, 4, and 5

• The zones are based on the intensity of earthquakes

• Zone 5 is the most seismically active zone

• The zones help in designing earthquake-resistant structures

Equivalent static method is a simplified approach to calculate seismic forces on a building.

• It assumes that the seismic forces can be represented by a single static force acting on the center of mass of the building.

• It is commonly used for low-rise buildings with regular shapes and uniform mass distribution.

• It is not suitable for tall or irregular buildings with significant mass and stiffness variations.

• The method is based on the concept of response spectrum analysis and can ...read more

Corner columns should be designed to resist both axial and bending loads.

• Consider the load-bearing capacity of the column material

• Determine the maximum load that the column will need to support

• Ensure that the column is properly braced to prevent buckling

• Design the column to resist both axial and bending loads

• Consider the geometry of the column and the surrounding structure

Seismic coefficient is a value used to calculate the seismic force acting on a structure during an earthquake.

• It is a factor that takes into account the seismic hazard of a particular location.

• It is used in the design of structures to ensure they can withstand seismic forces.

• The seismic coefficient is dependent on the soil type, building height, and other factors.

• It is typically expressed as a decimal or percentage.

• For example, a seismic coefficient of 0.2 means that the seis...read more

Reverse routing is the process of generating a URL based on a route name and parameters.

• Reverse routing helps in generating URLs dynamically based on route names and parameters

• It allows for cleaner and more maintainable code by decoupling URLs from the code

• Example: Generating a URL for a specific route like 'blog.post' with parameters like post ID
