Question

1. How is a force related to a load? Give four examples of loads AND how to strengthen a structure in response to that load.

Answer 1

Load is a term frequently used in engineering to mean the force exerted on a surface or body.

• force is the dynamic load { force= mass× acceleration} and it can act in any direction.
• on the other hand, load is a static load { F= mg} and it can act only in downward direction'

1. Dead loads are permanent loads which are carried to the structure throughout their lifespan. Dead loads are also called as stationary loads.

2.Live loads are also called as imposed or sudden loads. Live loads changes with respect to time.

3.This type of loads is considered only on the structure which receives snowfall during monsoon

4. This types of loads are considered in design if the height of the building is more than 15m. Wind loads are occurred due to the horizontal load caused by the wind

we can place an additional “bonded” reinforced concrete to an existing structural member in the form of an overlay or a jacket. With section enlargement, columns, beams, slabs, and walls can be enlarged to increase their load-carrying capacity or stiffness.
