“…The correct maintenance of their thermal and mechanical properties is crucial: indeed, each construction is subjected to the continuous degradation of structural and energy performance due to environmental actions, anthropic actions, and endogenous ageing (continuous degradation). In addition, they can be affected by episodic events like fire [1], explosions [2][3][4], and seismic actions [5][6][7] or other phenomena like deliberate attacks or human errors (discontinuous degradation). These events can sharply reduce the structural or energy performances of building and their service life.…”

Abstract:The retrofitting of existing masonry buildings is now a crucial problem for Europe. Indeed, structural safety and energy efficiency should represent the target of any renovation. The proposal of a new synthetic performance parameter is presented and discussed. Following this approach, in this paper, after a review of the main studies available in the literature, a proposal of a new performance parameter approach is presented and discussed. It is capable of taking into account both the structural and thermal aspects of masonry retrofitting. An emblematic set of reinforcements and energy improvements for masonry walls is examined. An example, generalized formulas, and a simultaneous evaluation of the role of multiple structural and thermal parameters on masonry buildings are proposed, with a view to optimize several categories of costs related to the intervention.

“…Concrete is a wide adopted building material. Its behavior under ordinary and extreme conditions, see Acito et al (2011), Stochino (2016), Stochino et al (2017), is a current and relevant topic. Likewise, the use of natural aggregates for its production presents an important problem for sustainable development (Etxeberria et al (2007)).…”

The results of an experimental investigation on cracking of fifteen reinforced recycled concrete slabs are presented in this paper. Five different recycled aggregates replacement percentages have been used for different mix design. First, the values of tensile strength, cylindrical compressive strength and modulus of elasticity of the concrete mixes have been determined. Then the deflection-load curve of the simply supported slabs have been obtained. The limit of the linear part of this curve determines the experimental cracking load. Its comparison with the theoretical value shows good agreement. Recycled concrete slabs show a similar performance to those made with ordinary concrete.

Fibre-reinforced plates and shells are finding an increasing interest in engineering applications; in most cases dynamic\ud phenomena need to be taken into account. Consequently, effective and robust computational tools are sought in order\ud to provide reliable results for the analysis of such structural models. In this paper the mixed assumed-strain laminated\ud plate element, previously used for static analyses, has been extended to the dynamic realm. This model is derived\ud within the framework of the so-called First-order Shear Deformation Theory (FSDT). What is peculiar in this assumedstrain\ud finite element is that in-plane strain components are modeled directly; the corresponding stress components are\ud deduced via constitutive law. By enforcing the equilibrium equations for each lamina, and taking continuity requirements\ud into account, the out-of-plane shear stresses are computed and, finally, constitutive law provides the corresponding\ud strains. The resulting global strain field depends only on a fixed number of parameters, regardless of the total number of\ud layers. Since the proposed element is not locking-prone, even in the thin plate limit, and provides an accurate description\ud of inter-laminar stresses, an extension to the dynamic range seems to be particularly attractive. The same kinematic\ud assumptions will lead to the formulation of a consistent mass matrix. The element, developed in this way, has been\ud extensively tested for several symmetric lamination sequences; comparison with available analytical solutions and with\ud numerical results obtained by refined 3-D models are also presented
