Moderate Seismic Regions

Buildings that rely on reinforced concrete walls and cores as their primary lateral loading system are prevalent in much of Australia’s building stock. Capacity design principles do not have to be adhered to in most low-to-moderate seismic regions, such as Australia. Consequentially, the level of detailing typically provided in accordance with the current and past concrete material standards, AS 3600 and AS 1480, is regarded as non-ductile from the seismic design point of view. These non-ductile reinforced concrete elements have been known to perform poorly when subjected to large lateral loads, as observed in the Christchurch earthquake in 2011. This paper presents an investigation into the seismic performance of C-shaped reinforced concrete walls acting as a core of a Mid-Rise building using current and past building codes in Australia. The displacement capacity of the building was calculated using a displacement-based assessment. A shear capacity model, which is a function of the curvature ductility of the walls, was also considered in the assessment. The results indicate that the older building is likely to fail in shear in the event of a 1000-year return period earthquake event. The building designed to current standards is vulnerable to a non-ductile failure from premature fracturing of the longitudinal reinforcing steel bars.

Family House

This essay presents the Saccomani family house, designed in the 1960s by Giandomenico Belotti in Fogajard, a cluster of isolated farmsteads near Madonna di Campiglio where, to this day, one may still breathe the farming life atmosphere of the times gone by. The clients developed a particular affection for the place and chose it for their free time. A bond is created and lives through a project that interprets the theme of the refuge in a modern way. Built at the margins of the meadows, at the limit of the woodland, the architecture abstracts the elements of tradition and translates them with today’s language, with no winking or analogies. The dry appearance of the exteriors, made of reinforced concrete walls, timber infills and a cantilevering horizontal roof, is matched by warm and welcoming interiors made of wooden and textile elements. It is through the architect’s coherent approach and his friendship with a passionate client that this work finds its particular shape, giving life to an authentic and honest experience of Alpine dwelling.
