Reversal of Stresses in Earthquake Load In earthquake-resistant design, understanding how stresses reverse due to seismic loads is crucial. Buildings are not only subjected to vertical gravity loads but also to dynamic lateral forces during an earthquake. Here's what happens: 🔁 1: Bidirectional Seismic Load Earthquake forces act in both directions (left and right). This leads to alternating tension and compression zones in the columns and beams. Reinforcement detailing must accommodate this rev
