Modelling of in-plane seismic behaviour of one-way steel or timber jack arch floors in existing buildings. Application to the Eixample district of Barcelona

The type of floor system has a decisive role in the seismic performance unreinforced masonry buildings. in-plane stiffness floors to be adequately represented numerical modelling existing buildings, as it can influence their capacity. This paper investigates behaviour one-way arch systems composed steel or timber beams, and ceramic tile vaults. main objective research is provide procedure for simplified jack assessment presented approach aims values orthotropic properties models elastic 2D shell elements. are computed calibrated by means comparisons with detailed 3D nonlinear floors. case study multi-storey building historical “Eixample” district Barcelona, which includes systems. Finite Element Method been used simulation through static (pushover) analyses. results contribute better understanding effect beams vaults on response work provides indicative proper these particular slabs. proposed methodology also applicable any other system.
