On the undrained cyclic resistance of a partially saturated sand [PDF]

E3S Web of Conferences
The undrained cyclic resistance of sandy soils is a key factor in controlling earthquake-induced damage. It is well established that the degree of saturation significantly influences the undrained behaviour of sands, as a reduction in saturation ...

Resistance of ETICS with Fire Barriers to Cyclic Hygrothermal Impact [PDF]

Sustainability, 2021
The article presents the results of a set of hygrothermal experiments of an external wall insulated with an ETICS. As an add-on to previous studies, thermal insulation in the form of polystyrene with an additional horizontal strip of mineral wool was used. Laboratory tests were carried out in accordance with ETAG 004. The ETICS test rig was composed of
