Large-scale additive manufacturing (AM), also known as 3D concrete printing, is becoming well-recognized and, therefore, has gained intensive research attention. However, this technology requires appropriate specifications and standard guidelines. Furthermore, the performance of printable in elevated temperature circumstances not yet been explored extensively. Hence, authors believe that there a demand for set standardized findings obtained with support experiments numerical modelling fire...

The modular construction industry often seeks cost-effective, high-performing, and longer-span members in buildings to ensure efficiency quality. Accordingly, the idea of built-up sections was brought into gain numerous benefits including higher structural capacity, improved torsional rigidity, increased stiffness. While limited research studies have been carried out study performances sections, few innovative section profiles developed considering benefits, Hence, application newly could...

Purpose Fire safety of a building is becoming prominent consideration due to the recent fire accidents and consequences in terms loss life property damage. ISO 834 standard test regulation simulation cannot be applied assess performance 3D printed concrete (3DPC) walls as real time-temperature curves could more severe, compared curve, maximum temperature time reach that temperature. Therefore, this paper aims describe an investigation on 3DPC composite wall panels subjected different...

Abstract Cold‐formed steel beams are often provided with web holes to accommodate service conduits. These result in reduced structural strength. Accurate estimation of the strength, including shear is crucial during design phase. There a lot studies available literature investigating strength reduction cold‐formed due holes. However, experiments and parametric finite element results were not assessed against Eurocode 3 provisions. Therefore, investigated herein. Existing experimental...

This study investigates the effect of 3-dimensional (3D) fibres on rheological properties self-compacting concrete (SCC) using three different fibre volume fractions (1%, 2% and 3%).Two sizes 3D with perimeters 115 mm 220 were considered.Rheological determined through slump flow, J-ring, V-funnel sieve segregation tests.The test results reveal that addition decreases workability SCC.3D a perimeter have more adverse SCC than mm.The balling occurred when 3% added to mixture, compromising SCC.

The use of 3D printing in modular building connections is a novel and promising technique. However, the performance printed steel has not been investigated adequately to date. Therefore, this paper presents three-dimensional finite element model (FEM), using multi-purpose software Abaqus, study effect different geometrical material parameters on ultimate behaviour (herein named 3DMBC) wire arc additive manufacturing (WAAM) method, as part UK’s 3DMBC (3D Modular Building Connections) project....
