This paper investigates the flow structure and pattern transition within a conical ribbed Taylor–Couette reactor (TCR), which is 4 mm in gap width 200 height, via particle image velocimetry (PIV) numerical simulation methods. The effect of various parameters on vortex transition, including structural ribs (rib spacing rib width) operating (Taylor number axial Reynolds number), were investigated...

Reinforced concrete (RC) as a material is most commonly used for buildings construction. Several floor systems are available following the structural and architectural requirements. The current research study provides cost input energy comparisons of RC office different systems. Conventional solid, ribbed, flat plate slab considered in study. Building models three-dimensional using extended ana...

Shear strength of precast concrete ribbed slabs reinforced with electro-welded lattice girders variable height is experimentally verified. Technical justification given for the use high latticework in reinforcement lightweight double-tee and 30 cm thickness. It was established that contribution to shear always higher than expected values according Spanish standards. Furthermore, as low exhibite...
