Understanding Structural Loads and Forces

The video tutorial explains different types of loads in structural engineering, including dead loads, live loads, superimposed loads, and service loads. Dead loads are constant and include the structure's self-weight, while live loads vary and include occupants and movable items. Superimposed loads encompass all external loads except self-weight, and service loads are the maximum expected loads during a structure's life. The tutorial also covers how to calculate these loads and the importance of safety factors.

What is a dead load in the context of structural engineering?

• A load that changes over time

• A load that remains constant throughout the structure's life

• A load caused by moving vehicles

• A load due to wind

How is the dead load of a slab typically calculated?

• By estimating the wind pressure

• By multiplying the slab's dimensions with the material's density

• By measuring the weight of furniture

• By counting the number of occupants

Which of the following is considered a live load?

• The weight of the foundation

• The self-weight of the structure

• The weight of permanent fixtures

• The weight of people and movable furniture

What is the minimum live load for a school classroom according to design specifications?

• 200 kg per M²

• 150 kg per M²

• 100 kg per M²

• 250 kg per M²

Which load is not considered a superimposed load?

• Self-weight of the structure

• Wind load

• Earthquake load

• Live load

What is a superimposed load?

• A load that includes all externally applied loads except the self-weight

• A load that is only due to wind

• A load that includes only the self-weight

• A load that is constant throughout the structure's life

What defines a service load?

• The load that is always constant

• The maximum expected load during the structure's life

• The load that includes only live loads

• The load that is only due to earthquakes

What is a factored load?

• A load without any safety factor

• A load with an additional safety factor applied

• A load that is only due to wind

• A load that is only due to live loads
