Using natural porous and fibrous materials for acoustic thermal conditioning in the construction sector is a solution to achieve comfort level buildings. The novelty of this research work lies employing agricultural agro-industry waste solve noise insulation problems. This study was conducted investigate multilayered panel made fruit stones coconut fibre from waste. Acoustic absorption, transmission, tests were run on four different stone types, olive, cherry, apricot peach, plus layer....

This research analyzes the solution of reinforced concrete joints with steel sections, known as (SRC). The aim is to verify improvement ductile characteristics structures compared conventional structures. Another objective better understand experimental behavior and thus be able perform numerical simulations adjusted ones. In addition, in all bars sections others which only are obtain more efficient economical All these objectives have main purpose improving against seismic loads. Five...

This paper presents a three-dimensional finite element model to confirm experimental tests carried out on steel reinforced concrete joints. The nonlinear behavior of this is simulated, along with its reduced capability resist large displacements in compression. aim was obtain the plastic beams numerical same way as obtained experimentally, which reduction strength post-critical stage considered simulate until structures collapsed. To do this, calculation necessary each material. Three models...

Sustainable and recycled materials are being used in a wide range of fields to solve waste management problem and, at the same time, confer them second life. These include fruit stones different crops: apricot, peach, cherry olive. Employing as acoustic contributes minimise environmental impact create new product with interesting sound-absorption properties, apart from offering aesthetic added value. Some previous works have demonstrated application panels sound absorbers. This study aims...

This article investigates the sound absorption coefficient of materials manufactured from natural wastes. Fruit stones some crops are one most available wastes in Mediterranean Region. Recycled and vegetable products becoming an interesting alternative to traditional be used as sound-absorbing panels. can profitable for a number applications, such biomass produce energy. research work intends demonstrate that their applications ecological absorbers building acoustics. Different four fruit...

A numerical model for the analysis of frame structures that is capable reproducing behavior reinforced concrete (RC) members and steel-reinforced (SRC) in all steps until collapse by simulating a reduced resistance capacity presented this work. Taking into account solid models obtained previous research have been validated experimental results, moment-curvature graphics were steps: elastic, plastic, post-critical to collapse. Beam versus 3D considerably simplified calculation correctly...

Abstract Ethylene vinyl acetate panels, with high content and a closed‐cell structure, were studied through various experimental techniques as first approach to evaluate the vibrational acoustic behaviour of ethylene panels for building applications. Test specimens, variety densities thicknesses tested influence these two parameters on impedance, sound transmission loss, dynamic stiffness attenuation vibrations. The results obtained shows loss values frequencies up 2500 Hz maximum about 63.7...

The aim of this study is to investigate the static and dynamic behaviour multilayer materials manufactured from granular recycled rubber applied technical flooring. studied samples were by varying their thickness, density granulometry, as these are parameters that determine performance rubbery materials. Two mechanical tests, dynamic, carried out under controlled conditions evaluate means its modulus elasticity stiffness. Relating stiffness impact sound insulation, it can be concluded...

A composite structure with steel reinforced concrete, SRC, has the strength of concrete and ductility steel, meaning that appropriate design can achieve high seismic resistance capacity.The present investigation shows results conclusions obtained from analyzing three different joints a structural frame tested increasing loading unloading cycles, one Reinforced Concrete, RC, another Steel third only same capacity as SRC section.We are able to give hyperstatic isostatic structures sufficient...

Due to the extinction of some wood species used manufacture guitars, there is a trend search new alternative materials with same acoustic performance. There wide range tonewoods: ebony, rosewood, yellow and red cedar, mongoy sapelli, among others. These woods have high resonance qualities requirements are both acoustical mechanical. In this work, composite been manufactured compare dynamic psychoacoustic parameters commonly woods. This comparison will allow conclude possibility using these...
