RESUMO:

Plaster is a binder used in folders, mortars and precast parts such as panels and blocks for civil construction. It is an abundant material, with low cost, lightweight, and a short setting time, that is easy to mold, and also has a good finishing surface and resistance to high temperatures and fire. However, the plaster has a fragile behavior and with low tenacity. These characteristics limit the possibilities of applying plaster in the construction sector. In order to reduce the mechanical limitations of plaster, and also aiming material's application in structural functions to expand the possibilities of application in civil construction, this work studied the mechanical behavior of sandwich panels consisting of two faces of plaster reinforced with fiberglass fabrics and an extruded polystyrene foam core. Using the commercial software SAP2000, three computational models of the sandwich panels were elaborated and the four-points bending test were reproduced. The numerical analyzes of the bending test were carried out, which made it possible to establish the parameters of loads, stresses, deformations and displacements of the sandwich panels. The investigation of these parameters, it was possible to verify that the sandwich panels that had greater thicknesses and volumes of reinforcements contained in the face materials had greater load support capacity, stiffness and tensile and compression strength.
