Prediction of concrete materials compressive strength using surrogate models

2022

Using soft computing methods could be of great interest in predicting the compressive strength of Ultra-High-Performance Fibre Reinforced Concrete (UHPFRC). Therefore, this study developed four soft computing techniques. The models are the Linear- relationship (LR), pure quadratic, M5P-tree (M5P), and artificial neural network (ANN). The models were trained and developed using 306 datasets comprising 11 input parameters, including the curing temperature (T), the water-to-cement ratio (w/c), silica fume (SF), cement content (C), fiber content (Fb), water (W), sand content (S), superplasticizer (SP), fiber aspect ratio (AR) and curing time (t). Experimental results were used and compared to t…

A model for SFRC beams without shear reinforcement

2008

In this paper a physical model, for the prediction of ultimate shear strength of Steel Fibers Reinforced Concrete (SFRC) beams is developed from the plastic Crack Sliding Model (CSM) introduced by Zhang (1997), based on the hypothesis that cracks can be transformed into yield lines. In this work the effectiveness factors are recalculated for SFRC beams and some further developments are introduced in the CSM, taking into account the fundamental post cracking tensile strength contribute of SFRC. The proposed model is validate by a large set of tests collected in literature and some numerical analyses were carried out to show the influence of fibers on the failure beams mode.

Properties of blended mortars produced with recycled by-products from different waste streams

2023

The construction industry encounters significant challenges in effectively managing solid waste produced during the extraction and production of building materials. In different countries, slurry waste generated from granite and marble processing industries, such as glass industry waste, constitutes a considerable portion of the total solid waste. Its undesirable disposal is causing unprecedented environmental damage. Using these non-biodegradable wastes to produce building materials would reduce the environmental burden and contribute to sustainable construction. This study, in detail, investigates the feasibility of utilizing Granite Powder (GP), Ground Granite Powder (GGP), and Ground Gl…

Development of a software package with GUI for the evaluation of monolithicity factors of RC jacketed columns

2023

The design of reinforced concrete (RC) jacketing for retrofitting substandard columns is a common practice when approaching the structural rehabilitation design of existing structures. In this framework, international technical codes suggest to assume the hypothesis of monolithic section and finally affecting the deduced performances by some empirical factors, known in the literature as monolithicity factors. The assessment of these coefficients is a difficult task, and only some rough assumptions can be found in the modern codes. This paper presents the development of a software package able to perform the static non-linear analysis of RC jacketed columns and evaluating the actual value of…

ARCHITETTURA E FOTOVOLTAICO: STRATEGIE E CRITERI D’INTEGRAZIONE. ARCHITECTURE AND PHOTOVOLTAICS: STRATEGIES AND INTEGRATION CRITERIA

2016

Nonostante i numerosi esempi positivi offerti dal panorama architettonico degli ultimi due decenni, alcuni studi hanno dimostrato come esistano ancora delle barriere che limitano l’impiego del fotovoltaico (FV) negli edifici e come spesso queste riguardino aspetti legati all’accettazione delle soluzioni utilizzate, specialmente sul piano della qualità architettonica. Il presente lavoro descrive e analizza alcuni dei numerosi esempi di nuova costruzione o retrofit, nei quali il FV diventa parte integrante del processo progettuale, non solo per gli aspetti concernenti la produzione di energia ma anche per quelli propriamente legati alla funzionalità dell’involucro edilizio, all’efficienza ene…

Giovani costruiscono spazi per giovani nella città universitaria di Palermo. Meeting places designed by students in the Palermo’s campus

2010

The paper reports the results of an International Design Workshop that every year is organized by E-D’ARC+ (a university students Association) in collaboration with some professors of the Courses of Building Engi¬neering and Architecture of the University of Palermo. This year the workshop was on the design of a small temporary architecture useful for young people -especially students- and its construction inside the campus of Palermo. Actually, the title of the Workshop was: "from Design to Construction". The students have designed small architectures by taking into account their experience inside the campus, in order to improve and to qualify it: a "urban environment" in which they spend …

Compatible rehabilitation of the Sicilian rural architecture: the case study of "Calcibaida" in Caltavuturo

2020

The Sicilian common typological form of rural estate is the masseria, typical of the latifundium. More particularly, it is a large fortified farm built to control and manage a vast land-property, the old fiefdoms. This paper will analyse the masseria Calcibaida as an eminent example of the mentioned Sicilian rural world. Calcibaida is located in the territory of Caltavuturo, in the centre of Sicily, within the mountain landscape of the Madonie mountains. The complex consists of a compact aggregate of buildings with an internal courtyard and a close large warehouse, further embellished by a fine drinking trough. The typological characteristics, materials and construction technologies of the …

Filigree constructions vs solid constructions. The relationship between structure and architecture in the contemporary age

2010

Historically, building shape and structure have been designed, in solid construction, at the same moment. Their relationship is evident in the organization of the building inner space. On the contrary, in filigree construction, the interior space isn't often directly defined by the structure and the separation between building's interior and exterior is much more clear especially if we consider contemporary architectures where filigree structures are frequently used. The paper points out the role of structure in relation to the building shape in the contemporary age. Different architectures have been analysed (such as high-rise and free-form buildings) in order to put in evidence the criter…

Thermochromic Thin Films: Synthesis, Properties and Energy Consumption Modelling

2013

Thermochromic materials such as vanadium dioxide have been postulated for use in “SMART” windows for a number of years. Such windows work by exploiting a structural phase change from an infra-red transmissive state to a infra-red reflective state. Significant challenges still remain before such materials will be able to find wide spread use. In this mini review we discuss the nature of this thermochromic transition with reference to the latest research work in the field. We pay particular attention to challenges such as film colouration, transition temperature, and transition hysteresis. We describe the most up to date strategies for addressing these challenges, considering advanced synthes…
