Incremental elastic-plastic analysis of a continuous steel beam with shakedown

open access: yesRUDN Journal of Engineering Research, 2014
An algorithm of the incremental elastic-plastic analysis of a continuous steel beam is presented in this paper. An elastic limit state has been determined, and formation of plastic hinges and collapse mechanism has been investigated.

Evaluation of seismic performance of steel frames with Y-shape braces under far-field and near-field earthquakes [PDF]

open access: yesNumerical Methods in Civil Engineering
In this study, the finite element modeling of the Y-shape bracing system is initially developed and verified. Next, the seismic performance of steel frames with Y-shape braces under far-field and near-field earthquakes was evaluated.

Seismic amelioration of existing reinforced concrete buildings. Strategy to optimize the amount of reinforcement for joints [PDF]

open access: yes, 2017
Most of the existing Reinforced Concrete (RC) buildings in Italy were built according to obsolete regulations that were not enough aware of issues related to seismic design so that they need to be upgraded by pursuing either amelioration or full seismic ...
