THE SUGGESTIONS AS TO THE CALCULATION BEARING CAPACITY OF SANDWICH REINFORCED CONCRETE — FOAMED CONCRETE FLOOR SLABS

Acta Polytechnica, 2019
This article presents the results of an experimental research of sandwich reinforced concrete-foamed concrete floor slabs. These floor slabs combine three different materials — normal concrete, foamed concrete and a steel reinforcement.

Behaviour of Self-Consolidating Concrete Two Way Slabs Under Uniform Loading

Iraqi Journal of Civil Engineering, 2012
An experimental investigation was conducted to study the strength, behaviour, and deflection characteristics of two-way slabs made with self-consolidating concrete and conventional concrete. Six slabs were tested to failure under simply supported uniform

Electro-welded lattice reinforcement in reinforced concrete ribbed slabs

Građevinar, 2021
Shear strength of precast concrete ribbed slabs reinforced with electro-welded lattice girders of variable height is experimentally verified. Technical justification is given for the use of high latticework in the reinforcement of precast lightweight ...

Application of Fractal Theory to the Analysis of Failure Characteristics of Low-Velocity-Impact Concrete Slabs

Buildings, 2023
The fractal characteristics of low-velocity-impact concrete slabs were studied using fractal theory, and the fractal dimension value of cracks of each concrete specimen plate was calculated using box dimension as the basic principle and digital image ...

Comparison of the post-tensioned, solid, hollow block, and flat slabs in terms of economy considering different span lengths

International Journal of Applied Mechanics and Engineering, 2023
From among the several types of slabs, there is uncertainty about the most cost-effective one for structures with short, medium, and long spans. A study comparing the cost of the solid, flat, hollow block (HB), and post-tensioned (PT) slabs for 4, 6, and

Flexural analysis of RC rectangular slabs subjected to patch load

Alexandria Engineering Journal, 2018
Many reinforced concrete slabs are subjected to heavy concentrated loads. Deck slabs in slab/girder bridges are subjected to wheel load distributed on contact area touches the slab surface. A large number of rectangular concrete slabs were analyzed using

Digitally fabricated ribbed concrete floor slabs: a sustainable solution for construction

RILEM Technical Letters, 2022
The concrete used in floor slabs accounts for large greenhouse gas emissions in building construction. Solid slabs, often used today, consume much more concrete than ribbed slabs built by pioneer structural engineers like Hennebique, Arcangeli and Nervi.

Analysis of adequacy of recycling the São Paulo Metropolitan Ring Road concrete pavement as new pavement [PDF]

Revista IBRACON de Estruturas e Materiais
The west section of the Governor Mário Covas São Paulo Metropolitan Road Ring was opened to traffic in 2002. The original pavement was a jointed plain concrete pavement with dowelled joints and a design flexural strength (or modulus of rupture) of 4.5 ...

Fibrous Reinforced Concrete Slabs

University of Khartoum Engineering Journal, 2022
The paper presents the results of a theoretical and an experimental work performed at the KhartoumUniversity, Civil Engineering Department Structure lab. The work aimed to obtain knowledge concerning theinfluence of steel fibers on the behaviour of reinforced concrete slabs. A comparative study was conductedtheoretically and experimentally.
