Abstract: This paper studies interaction response between the spandrel beam and floor beams with different floor beam properties using ANSYS14.0 nonlinear models. A three-dimensional finite element models have been established to provide a numerical solution as an alternative theoretical approach with some acceptable accuracy. The calculated ultimate loads, torque and angel of twist are compared with the experimental observation of twenty two statically indeterminate spandrel-floor beams and very good agreement is observed. Parametric study are presented to clarify the effect of floor beam length to the spandrel beam length ratio, depth of the floor beam to spandrel beam ratio. Empirical expressions are presented.

Abstract: Despite its economic importance, mining activity for aggregate production (sand, gravel and crushed stone), may lead to an over-exploitation of the natural environment. This paper aims to evaluate the needs of aggregates associated with urban plans for the municipalities of Cagliari, Tortolì and Sant'Antioco (Sardinia island, Italy), also identifying the potential for recycling of construction and demolition waste, in particular of concrete. The geographical position of Sardinia prevents trade of recycled aggregates, confirming that the whole needs of aggregates can economically be satisfied only by local products. In order to meet the demand for aggregates from building industry and infrastructures, the combined use of natural and recycled aggregates, although desirable (EU Parliament, 2008), is not really suitable. It was therefore proposed another way, based on keeping the levy of recycled aggregates closely linked to the implementation of urban plans through the introduction of a n
