Application of a new methodology based on Eurocodes and finite element simulation to the assessment of a romanesque church

• Methodology based on Eurocodes and analysis of discontinuous MEF model is presented.
• Eurocodes reliability criterion and classical limit analysis approach are combined.
• Methodology allows checking all the ultimate limit states in any design situation.
• Ultimate limit states of SEQ, with sliding between blocks, STR and SBC are analyzed.
• Collapse progress can be predicted in case that the structure loses the stability.

This work proposes a methodology, based on finite element simulation, for analyzing masonry historical structures, according to Eurocodes, that has been applied for the assessment of the Saint Sebastian church, located in Piedratajada (Zaragoza, Spain). Settlement pathologies were detected and the aim of the work is to verify the current safety level and to propose reinforcement solutions if necessary. Results confirm the effect of soil settlement and allow establish the maximum admissible value. If that value is reached, a couple of reinforcement solutions, installing sheets of steel or carbon fiber composite, are proposed and analyzed.
