10 Questions
Explain the concept of inertia forces in structures during an earthquake and how it affects the building's movement?
During an earthquake, the base of a building moves with the ground while the roof tends to stay in its original position due to inertia. The walls and columns, being connected to the roof, drag it along with them, causing the building to experience motion at its base. This is similar to the situation when a bus suddenly starts, and your upper body tends to stay back. The tendency to remain in the previous position is known as inertia.
How does Newton's First Law of Motion relate to the movement of buildings during an earthquake?
Newton's First Law of Motion states that an object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force. In the context of buildings during an earthquake, this law explains why the base of the building moves with the ground while the roof tends to stay in its original position due to inertia.
What role do the walls and columns play in the movement of the roof during an earthquake?
The walls and columns, being connected to the roof, drag it along with them during an earthquake. This causes the building to experience motion at its base, as the roof tends to stay in its original position due to inertia.
How does the flexibility of walls and columns impact the motion of the roof during an earthquake?
In a building, since the walls or columns are flexible, the motion of the roof is different from that of the ground. This difference in motion contributes to the building's response to the seismic effects.
What is the significance of the tendency of columns to resist deformations during an earthquake?
During an earthquake, the tendency of columns to resist deformations is significant as it contributes to the building's stability and its ability to come back to a straight vertical position, thus minimizing damage.
The flexibility of walls and columns causes the motion of the roof to be different from that of the ground during an earthquake.
True
The tendency of columns to resist deformations during an earthquake makes them more susceptible to damage.
False
During an earthquake, a building resting on the ground experiences motion at its base, while the roof tends to stay in its original position due to Newton's First Law of Motion.
True
Inertia is the tendency of an object to continue to remain in its previous position, which is also observed in the movement of buildings during an earthquake.
True
The seismic effects on structures primarily involve the resistance of walls and columns to deformations during an earthquake.
False
