What are the shortcomings of grillage analysis which is commonly used in structural analysis of bridges?
Answer: Grillage analysis suffers from the following shortcomings based on E. C. Hambly:
Answer: Grillage analysis suffers from the following shortcomings based on E. C. Hambly:
- For coarse mesh, torques may not be identical in orthogonal directions. Similarly, twists may differ in orthogonal directions.
- Moment in any beams is mainly proportional to its curvature only. However, moment in an element depends on the curvatures in the beam’s direction and its orthogonal direction.
