- Abstract
- Pushover analyses are often used to evaluate the seismic performance of a structure.They give an estimate of the ultimate displacement a structure can undergo, as well as of theresidual resisting forces in the post-peak response. When modelling masonry structurescomposed of multiple blocks, obtaining the post-peak branch of the pushover curve can bedifficult with a classic displacement-control strategy. This paper describes a strategy designedto compute this branch for multi-block systems subjected to a given pattern of forces, withoutthe need to apply a displacement-control algorithm. The strategy is general, thereforestraightforwardly implementable in different software tools and applicable to complex blockassemblies. In the present work, it is implemented in two different DEM software, namelyLMCG90 and UDEC, and tested on a benchmark problem for evaluating the in-plane responseof masonry walls.
