Background: Seismic risk mitigation has become a crucial issue due to the great number of casualties and large economic losses registered after recent earthquakes. In particular, unreinforced masonry constructions built before modern seismic codes, common in Italy other seismic-prone areas, are characterized by vulnerability. order implement policies, analytical tools necessary generate scenari...

The dynamic stability of out-of-plane masonry walls can be assessed through non-linear analysis (rocking analysis), accounting for transverse walls, horizontal diaphragms and tie-rods. Steel tie-rods are widely spread in historical constructions to prevent dangerous overturning mechanisms simulated by proper elasto-plastic models. Conventionally, design guidelines suggest intensity-based assess...

In the present paper, Fragility Curves (FCs) of Reinforced Concrete (RC) building types with moment-resisting frame structure representative existing Italian stock have been derived through an analytical approach. The proposed methodology is based on Non-Linear Dynamic Analyses encompassing all steps required to bring about reliable as well realistic fragility results. First, prototype selected...

This paper presents a Bayesian-estimation-based seismic fragility assessment method that can significantly reduce the computational burden. The likelihood function and prior distribution used in Bayesian estimation were enhanced. A probability density of capacity was adopted as function, although previous studies have generally curve. Further, assumed based on obtained by incremental dynamic an...

Abstract Assessment of churches based on empirical data at a territorial scale is suitable tool to have an overview the seismic behaviour this peculiar structural typology and evaluate their current state vulnerability. Fragility vulnerability curves are also aimed perform analysis different scenarios. The paper presents detailed typological 633 single-nave churches, as selected subset database...
