Abstract The main vulnerability models available in the literature aim to develop damage fragility curves estimate level suffered by a building after seismic event. However, recent earthquakes have highlighted great importance of predicting usability residential buildings, i.e. condition being habitable or occupiable performance can be used as an indicator for allocating economic funding event ...

The recent re-assessment of the seismic hazard in Europe led for many regions of low to moderate seismicity to an increase in the seismic demand. As a consequence, several modern unreinforced masonry (URM) buildings, constructed with reinforced concrete (RC) slabs that provide an efficient rigid diaphragm action, no longer satisfy the seismic design check and have been retrofitted by adding or ...

This paper applies Thrust-Network Analysis, a three-dimensional computational method for obtaining lower-bound solutions of masonry vaults with complex geometries. The method extends thrust-line analysis to three-dimensional problems by finding equilibrium force networks within the vault’s geometry, representing possible paths of the compression forces. Through two case studies, this paper demo...
