Prenons l’exemple d’un chantier de construction qui a besoin d’un entrepôt.
Le site comporte une pile de blocs de maçonnerie en béton de dimensions nominales de 8 pouces de largeur et de profondeur et de 16 pouces de longueur, utilisés pour la construction de l’entrepôt.
L’ingénieur de chantier doit concevoir l’entrepôt de manière à ce que les blocs de 16 pouces de longueur soient placés avec précision dans les murs sans avoir à couper les blocs.
Les dimensions de la pièce dans le plan sont de 12 pieds de longueur et 8 pieds de largeur, mesurées à partir des coins extérieurs.
Les dimensions réelles du bloc sont légèrement inférieures aux dimensions nominales. Les dimensions du bloc et l’épaisseur du mortier donnent ensemble une longueur de 16 pouces.
Aujourd’hui, il faut précisément 9 blocs pour la dimension la plus longue du mur et 6 pour la plus courte.
Avec cette disposition, les dimensions intérieures de la pièce deviennent de 10 pieds 8 pouces dans le sens le plus long et de 6 pieds 8 pouces dans le sens le plus court.
Cette pratique évite de couper les blocs et assure une construction plus rapide et une finition parfaite.

exemple de conception: dimensionnement d'une construction en maçonnerie de béton

Pour la construction d'un local de stockage en éléments de maçonnerie de béton, il est essentiel d'aligner les dimensions de la structure avec les dimensions réelles des blocs et les joints de mortier prévus. Sur le chantier en question, il existe un stock de blocs de maçonnerie en béton d'une taille nominale de 20,32 x 20,32 x 40,64 centimètres, qui doivent être utilisés pour la construction du local de stockage.


 L'ingénieur du chantier a établi un plan pour le local de stockage avec des dimensions extérieures de 3,66 mètres de longueur et 2,44 mètres de largeur. Pour s'aligner sur ces dimensions, le plan prévoit l'utilisation de neuf blocs pour la longueur des murs et de six blocs pour la largeur. Cependant, la taille réelle de chaque bloc est de 19,37 centimètres de hauteur et de 39,37 centimètres de largeur, avec une marge de 0,95 centimètre pour le joint de mortier. Une fois combiné au mortier, cela donnera une longueur de bloc effective de 40,64 centimètres.


 Ce calcul garantit que les blocs posés bout à bout rempliront les dimensions prévues sans qu'il soit nécessaire de les découper, ce qui permet un processus de construction plus rapide et une finition professionnelle. En conséquence, les dimensions intérieures des murs du local de stockage mesureront 3,05 mètres sur 0,20 mètre de longueur et 1,83 mètre sur 0,20 mètre de largeur une fois la construction terminée. Cette approche méthodique de l'utilisation des matériaux garantit l'efficacité de la construction et un résultat esthétique propre pour le local.

Design Example: Dimensioning of Concrete Masonry Construction

sizing a storeroom with masonry blocks

Sizing a storeroom with concrete masonry blocks starts with matching the wall plan to the actual block size and mortar joints. The site has concrete masonry units with a nominal size of 8 by 8 by 16 inches. The storeroom is planned with external dimensions of 12 feet long and 8 feet wide.

The wall layout uses nine blocks along the length and six blocks along the width. Each block is actually 7 and 5/8 inches high and wide, and 15 and 5/8 inches long. A 3/8 inch mortar joint is included, so the effective block length becomes 16 inches when the blocks are set together.

This sizing method lets the blocks fit the planned dimensions without cutting. That makes construction faster and gives the storeroom a clean, professional finish. After the walls are built, the internal dimensions measure 10 feet 8 inches in length and 6 feet 8 inches in width.

Concrete Pavement Joint Types and Functions

Concrete pavement joints guide where slabs crack and help protect the pavement over time. They support the structural integrity and long life of the concrete by controlling movement and cracking. Contraction joints, also called control joints, are made by sawing a groove into the concrete soon after it hardens. This groove creates a weakened vertical plane. It encourages cracking at a planned location instead of letting cracks form randomly across the slab. Isolation joints are used where the...

design example: aggregate gradation

Choosing Well-Graded Sand for Concrete

Well-graded sand is important in concrete because aggregate choice affects strength, mix proportions, and cost. In concrete, sand is the common fine aggregate. When more than one sand source is available, its gradation often guides the selection. Gradation means the particle-size distribution of the sand. Engineers measure it with sieve analysis, which uses standard sieve sizes from 150 μm to 10 mm, from ASTM No. 100 to the 3/8 in. sieve. This test shows how much sand stays on each sieve and...

design example: managing concrete workability

Concrete Slump Test in Hot Weather

Concrete slump testing helps track workability during a raft foundation pour in hot weather. Workability means fresh concrete is easy to place, compact, and finish. In this example, the concrete had to be prepared for a large foundation, so keeping it workable was important for quality and durability. The first slump test showed low workability. The mix was losing water quickly, and the high temperature made the coarse aggregates hotter as well. To reduce that effect, the site engineer cooled...

Sizing Steel Bars for a Concrete Beam

Sizing steel bars for a concrete beam helps meet a required reinforcement area. In reinforced concrete design, the steel must be arranged so the beam stays strong and uses material efficiently. This example uses a beam that needs a total steel cross-section of 4 square inches. The available bars in the example have a nominal diameter of 1.693 inches. Each bar provides a cross-sectional area of 2.25 square inches. When the engineer divides the required area by the area of one bar, the result is...

Green Features in a Concrete Building

A sustainable concrete building can use several green design features to save energy, water, and materials. Concrete is a flexible material for these choices, so it supports eco-friendly construction in commercial buildings. One strategy is to place a concrete parking area under the building. Open areas can use pervious concrete paver blocks, which let rainwater pass through and collect in an underground cistern. That stored water can then be reused for gardening, which improves water...
