In unreinforced masonry (URM) structures vertical walls are connected by horizontal spandrel elements. Spandrels have been subjected to extensive damage during earthquakes and are often the first elements within a URM building to crack or fail. If URM buil ...
This article presents the test setup of two quasi-static cyclic tests on U-shaped walls under horizontal diagonal loading recently performed at EPF Lausanne. The results of the first test are discussed in terms of global behaviour: failure mechanisms and f ...
This paper presents a plastic hinge modelling approach for wall-type bridge piers with detailing deficiencies such as low transverse reinforcement ratios and lap splices in potential plastic hinge regions. Currently available plastic hinge length estimates ...
Cultural heritage buildings were typically built without considering seismic action and are therefore potentially susceptible to earthquake damage. The performance states and protection objectives developed for ordinary buildings are not directly applicabl ...
O dano severo e o colapso de diversos edifícios com paredes estruturais em betão armado (BA) durante os recentes sismos do Chile (2010) e Nova Zelândia (2011) revelaram que muitas paredes de BA não tiveram o desempenho que seria expectável da aplicação das ...
For a shake table test on a four-storey structure with both unreinforced hollow-core brick masonry (URM) walls and reinforced concrete (RC) walls, the test unit had to be constructed at half-scale. While past experience showed that testing RC structural el ...
This paper presents the first part of a series of uniaxial cyclic tests on lap-splices. The work is conducted within the framework of a project on the seismic behaviour of existing, poorly detailed bridge piers which are typically constructed with a lap-sp ...
In existing European recommendations the drift capacity of unreinforced masonry (URM) piers is estimated as a function of the failure mode, aspect ratio and/or axial load ratio. The empirical relationships are based on a set of results from quasi-static cy ...
With the introduction of higher seismic design forces in the Swiss loading standard of 2003 most unreinforced masonry (URM) buildings failed to satisfy the seismic design check. For this reason, in new construction projects, a number of URM walls are nowad ...
Although mixed reinforced concrete (RC) - unreinforced masonry (URM) wall structures are often used, experimental and numerical studies on their seismic behaviour are scarce. Previous studies pointed out that the obtained results from numerical simulations ...
