Samen onder één dak betekent in oudere appartementcomplexen vaak: samen gebukt onder een veel te hoge energierekening. En dat hoeft niet! Dat het ook anders kan, bewijzen de zeven VvE's die in dit boekje aan verduurzaming van hun complex hebben gewerkt. Dat hebben ze gedaan door er samen de schouders onder te zetten en creatieve oplossingen te bedenken. Hun argumenten: lagere woonlasten (hypotheek- en energielasten bij elkaar) en waarde toevoegen aan hun woning...

Out-of-plane (OOP) wall collapse is one of the most common failure mechanismsin unreinforced masonry (URM) structures. Insufficient connections at wall-to-wall, wall-to-floor or wall-to-roof levels are one of the main reasons for OOP failures. The seismic assessment of URM buildings with insufficient connections became of high relevance. In particular, cavity walls are widely used in many regions, such as Central and Northern Europe, Australia, New Zealand, China, and Groningen in the Netherlands. Defining thus the behaviour of such connections is of prime importance to understand the overall response of URM buildings.This paper is about an experimental campaign conducted at the BuildinG laboratory of Hanze University of Applied Sciences on timber joist-masonry connections, reproducing cavity walls with timber joists in as-built condition. A total of six URM tests were performed, with varying configurations as: two different tie distributions, two precompression levels and two different as-built connections. The tests aim at providing a complete characterization of the behaviour of the timber-joist cavity-wall connections under axial cyclic loading with special attention on the developed failure mechanism and the definition of force-displacement curves for each group of tests performed. The experimental results show that cohesion and friction between joist and masonry are important parameters in terms of the governing failure mechanism, whether it is a joist-sliding or rocking failure.
