- •
An analytical model to predict the response of a frame beam subjected to blast loading is proposed.
- •
The lateral restraint may significantly reduce the required ductility at the beam level.
- •
The M–N interaction developing in the yielded zone increases the required ductility at the beam level.
- •
The asymptotic solutions provide a good level of accuracy, with a maximum error of 6%.
