Historical Development and Seismic Performance of Unreinforced Masonry Buildings with Vertical Extensions in the City Centre of Barcelona

Savvas Saloustros

This paper presents the historical development of the vertical extensions of unreinforced masonry buildings in the Eixample district of Barcelona and their impact on the seismic behaviour. Existing masonry buildings of Eixample present significant seismic ...

Seismic response of historical masonry buildings and aggregates - large-scale experimental testing and macro-element modelling

Igor Tomic

The seismic analysis of existing unreinforced masonry buildings is a challenging task, troubled by different sources of material and modelling uncertainties. The historical heritage value of a building can further complicate the assessment and design of re ...

Seismic Performance of Strengthened Slab-Column Connections in a Full-Scale Test

Aurelio Muttoni

Strengthening of flat slab-column connections to resist imposed lateral drifts is often required for older reinforced concrete structures in which the flat slabs were typically designed to resist gravity load only or have been designed for less stringent r ...

The impact of uncertainties on post-earthquake response predictions of a building with unreinforced masonry walls

Ian Smith, Katrin Beyer, Mathias Christian Haindl Carvallo

In this paper, the impact of several sources of uncertainty on the seismic response of an experimentally tested building is assessed for the case of a post-earthquake scenario. The building comprises unreinforced masonry and reinforced concrete walls. It i ...

Modelling of in-plane seismic behaviour of one-way steel or timber jack arch floors in existing buildings

Savvas Saloustros

The type of floor system has a decisive role in the seismic performance of unreinforced masonry buildings. The in-plane stiffness of the floors has to be adequately represented in the numerical modelling of existing buildings, as it can influence their sei ...

Latest findings on the behaviour factor q for the seismic design of URM buildings

Katrin Beyer

Recent earthquakes as the 2012 Emilia earthquake sequence showed that recently built unreinforced masonry (URM) buildings behaved much better than expected and sustained, despite the maximum PGA values ranged between 0.20-0.30 g, either minor damage or str ...

The Role of the Composite Floor System and Framing Action in the Seismic Performance of Composite Steel Moment-Resisting Frames

Hammad El Jisr

With the advent of performance-based earthquake engineering (PBEE), the need for reliable prediction of earthquake-induced collapse of structures is essential. Despite the significant progress that has been made towards this goal, there are several hurdles ...
