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 ...
Reinforced concrete slabs without shear reinforcement under concentrated loads near linear supports are typical cases of bridge deck slabs, transfer slabs or pile caps. Such members are often designed or assessed in shear/punching shear with code provision ...
Of the various types of road structures, bridges are the most exposed to icing; the problem of icing is widely addressed through salting, which reduces the lifespan of the bridge. One promising solution to avoid the use of salt is the seasonal storage of s ...
To embed the diversity and variability of human needs as foundational elements of daylighting design and put human occupants back at the core of the building question, we need to reach out to fundamental discoveries from neuroscience, biology and other fie ...
RC slabs without shear reinforcement subjected to c oncentrated loads near lin ear supports are typical cases of deck slabs of bridges, transfer slabs or pile caps. Such elements are often designed or as sessed in shear with code provisions calibrated on ...

This paper quantifies the lateral overstrength and the collapse risk of steel buildings with perimeter special moment frames (SMFs) designed in highly seismic regions in North America. State-of-the-art analytical models that consider the contributions of t ...
The development of ground source heat pumps has facilitated the use of geothermal power at shallow depths. Initially, ground heat exchangers were buried in trenches or boreholes, but recent investigations and increasing congestion of landscapes have sugges ...
Energy pile foundation can expel and extract heat into and from the ground in summer and winter, respectively. The discharge and extraction of heat induce cyclic thermal load in piles and may lead to serviceability problems. So far, the effects of cyclic h ...
In this paper we use the novel Disturbed Stress Field Model (DSFM) from Facconi et al. (2013) to model the lateral in-plane behaviour of different unreinforced masonry (URM) walls which we tested at the laboratory of the EPF Lausanne, Switzerland. The mode ...
Using pile foundations as heat exchangers with the ground provides an efficient and reliable energy source for the heating and cooling of buildings. However, thermal expansion or contraction of the concrete brings new challenges to the design of such struc ...
