Abstract Concrete is the most widely used construction material. Worldwide consumption of cement, strength‐giving component in concrete, now estimated to be 4.10 Gt per year, having risen from 2.22 just 10 years ago. This rate means that cement manufacture alone account for 5.2 % global carbon dioxide emissions. offers opportunity create structures with almost any geometry economically. Yet its unique fluidity seldom capitalized upon, concrete instead being cast rigid, flat moulds...
Concrete shell structures offer a mechanically efficient solution as building floor system to reduce the environmental impact of our buildings. Although curved geometry shells can be an obstacle their fabrication and implementation, digital affordable robotics provide means for automation construction in sustainable manner at industrial scale. The applicability such is demonstrated this paper with realisation large-scale concrete system, completed by columns, tie rods, levelled floor. was...
Cold-formed steel (CFS) construction can lead to more efficient designs compared hot-rolled members as a consequence of its high strength, light weight, ease fabrication, and flexibility in their cross-section profiles. However, CFS are vulnerable local, distortional overall buckling modes. This paper develops numerical model investigate the flexural strength failure modes back-to-back channel beams verifies efficiency an optimisation framework previously proposed. The incorporates...
Courtyard blocks are well known for their tempering potential of the thermal conditions in various climates. In this paper, building heights, orientation and interspaces courtyard optimised hot-arid climate Cairo, Egypt. Simulations conducted using an evolutionary search algorithm within Grasshopper parametric design environment Rhino 3D. The Ladybug-tools, plugins were used to calculate objective functions, summer weekly cooling loads average Universal Thermal Climate Index (UTCI). For...
The recent reports from the Intergovernmental Panel on Climate Change (IPCC) urge for reconceptualization of our design urban built environments. However, current efforts to integrate environmental assessment into practice in Egypt are proving insufficient. This paper utilises Ladybug tools simulation plugins investigate impact changing morphological characteristics three-block typologies (scattered, linear and courtyard) their associated parameters understand multidimensional relationship...
Doubly-curved ribbed concrete shells are a materially efficient means of spanning large areas such as roofs and floors. However, the fabrication structures poses challenges in terms formwork manufacturing well material deposition. This has led to their decline compared more prismatic shapes flat slabs which can be manufactured economically. paper presents novel process called Automated Robotic Concrete Spraying (ARCS) by glass fibre reinforced (GFRC) is sprayed onto curved create thin shell...
This paper describes an experimental program carried out at the University of Sheffield to investigate interaction local and distortional buckling in cold-formed steel lipped channel beams. The channels were arranged a back-to-back configuration total six tests, including three different cross-sectional geometries, completed. specimens tested four-point bending with simply supported boundary conditions while being laterally braced loading points. beams failed constant moment span by...
Additive Manufacturing (AM) methods in the construction industry typically employ ground-based deposition methods. An alternative to transform role of AM is introduce an aerial capability. A recent project titled Aerial (AAM), first system use untethered, unmanned vehicles (or ‘drones’), has demonstrated 3D-printing cementitious materials during flight. autonomous would minimise requirements for working at height, thus reducing safety risks and release from constraints. This study...
Additive manufacturing in construction typically consists of ground-based platforms. Introducing aerial capabilities offers scope to create or repair structures dangerous elevated locations. The Aerial Manufacturing (AAM) project has developed a pioneering approach using Unmanned Vehicles (UAV, ‘drones’) deposit material during self-powered, autonomous, untethered flight. This study investigates high and low-density foams autonomously deposited as structural insulation materials. Drilling...
A bland diet with the odor of meat or air blown through it was presented to Beagle dogs in daily two choice preference tests. At first, there a 70010 for food that smelled like but, by third week, had fallen 520/0. These results indicated that, although initially prefer smells meat, must be paired some other property probably taste, preferences sustained. Intact significantly preferred lamb over horsemeat 67 ± 4010, pork 89 3010, 89± beef 84 2010, and 2010 Dogs made anosmic intranasal...
