A large number of cultural heritage buildings, especially in the Mediterranean area, belong to dry masonry stone structures. In order be able make decisions about possibly necessary rehabilitation techniques and preserve them for future generations, it is have insight into their behaviour due expected actions, most destructive which an earthquake. As part this work, assessment seismic resistance four structures old centre Split Croatia was carried out: bell tower Cathedral Saint Domnius,...

The behaviour of the earthquake excitated reinforced concrete (RC) structures up to collapse, previously designed according prescriptions Eurocode 8 cannot be fully predetermined because diversity nature earthquake. Thus, one needs make a judicious choice between two ductility classes balancing desired response structure, dimension structural elements, costs and complexity design construction. Powerful numerical models stand as significant tools obtain more insight into peculiarity each...

The aim of this study is to investigate the seismic resistance dry stone arches under in-plane loading. For that purpose, several numerical analyses were performed using combined finite-discrete element method (FDEM). Twelve types with different ratios a rise at mid-span span, thicknesses blocks and numbers in arch subjected an incremental dynamic analysis based on excitation from three real horizontal vertical ground motions. minimum value failure peak acceleration caused collapse was...

It was significantly damaged during earthquake which occurred 22 March 2020 with magnitude 5.5. performed simplified FDEM 2D numerical model corresponds structure its current pre-disaster state after proposed post-disaster...

Target acceleration in multimodal pushover method for R/C framesThe procedure of searching the target ground as a measure lowest seismic resistance is presented paper.This objective achieved by analysis based on envelope principle.The founded linear combination modes (L), and mode combinations square root sum squares (SRSS), presented.Examples 5-storey 9-storey frames point to highly significant influence higher modes.The failure significantly lower, even several times compared single acceleration.

Purpose – The purpose of this paper is to present a new modification the multimodal pushover method, named target acceleration method. minimum base that leads ultimate limit state structure, i.e., lowest seismic resistance. Design/methodology/approach A nonlinear numerical model used determine acceleration, which achieved using iterative procedure according envelope principle. Validation method was conducted on basis results obtained by incremental dynamic analysis. Findings influence higher...

In this paper, a series of incremental dynamic analyses were performed on five masonry towers resting the base, whose geometry was taken from literature, in order to determine how difference geometric characteristics and deformability subsoil affect global behaviour, failure mechanism seismic resistance towers. Special attention attributed determining whether experience rocking motion during excitation, which proved be suitable terms energy dissipation earthquake resistance. Analyses carried...

This paper presents a computationally efficient numerical model for the analysis of thin shells based on rotation-free triangular finite elements. The geometry structure in vicinity observed element is approximated through controlled domain consisting nodes and three adjacent elements between which second-order spatial polynomial defined. considers large displacements, rotations, small strains, material geometrical nonlinearity. Material nonlinearity implemented by considering von Mises...

This paper presents a failure analysis of the bell tower The Church St. Francis Assisi on Kaptol in Zagreb seismic action using Finite-Discrete Element method -FDEM.The is made masonry, and throughout history it has had number damages reconstructions.It was significantly damaged Petrinja earthquakes.The performed simplified FDEM 2D model, obtained results showed good match between direction cracks numerical model that occurred due to these earthquakes.

Crack opening is one of the dominant causes nonlinearity in brittle and quasibrittle structures which leads to localized failure stands out as a serious challenge numerical modelling.Therefore, realistic modelling crack initiation propagation key factors that affect reliability model for analysing structures, especially those subjected earthquakes.The largest number world's most populated seismic areas made materials such reinforced concrete, stone masonry, dominantly influences structural...
