- •
An analytical model is proposed for out-of-plane dynamic analysis of URM walls.
- •
The model has 2-DOF and considers the wall attached to a flexible diaphragm.
- •
Two rigid bodies are connected by intermediate hinge and restrained by a top spring.
- •
The equations of motion of the 2-DOF model are derived.
- •
Time-history analyses are performed on walls with variable spring stiffness.
