Abstract text:
The interest towards the ecological materials and the advanced technology have led to the research of a new type of additives and substances that can successfully replace Portland cement, integral or partially. Starting from the obtained results on this type of materials and noticing their capacity to be combined in composite materials that can be reinforced with random glass and polypropylene fibre, an integral hybrid structural system, with multiply panels, for an individual dwelling house, was constructed. The final shape of the panels bearing structure is plate type with stiffening ribs on vertical and horizontal direction. The solution of technical issue consists in total replacing of the steel reinforcing bars with glass fibres (synthetic or natural) and also in the replacement of a Portland cement percentage. This experiment proposes the testing of an innovative one level structure, scale 1:1, under typical seismic loading for Romanian structural design, to note its behaviour, seismic energy dissipation and failing. The experimental model was progressively tested with field acceleration maximum values varying between 0.1 g and 0.9 g.
