Uneven distribution of mass in a building can cause serious structural problems during an earthquake. Proper mass distribution is essential for ensuring stability and minimizing damage. Here's why:

1️⃣ Balanced Mass Distribution (✅ Safe Design)

When mass is evenly distributed, the entire building moves together during an earthquake.
No excessive forces are concentrated in specific columns.
The structure remains stable with reduced risk of collapse.
2️⃣ Unbalanced Mass Distribution (❌ Unsafe Design)

Heavy sections of the building create excessive force on extreme columns.
This imbalance leads to twisting (torsion), increasing the risk of structural failure.
Uneven mass can amplify lateral forces, making the building vulnerable to seismic damage.
✅ Solution:

Design buildings with uniform weight distribution.
Avoid heavy concentrated loads on one side.
Follow seismic design guidelines to enhance earthquake resistance.
