Mortar Joints in Brick Masonry01:25

Mortar Joints in Brick Masonry

212
Mortar joints play a critical role in brick masonry, filling the spaces between brick to bind them together and provide structural integrity and strength. The thickness of these joints is variable, typically ranging from less than one-fourth inch to over half an inch, based on structural needs and specific applications.
The process of joint tooling is implemented as the mortar begins to harden. This technique involves compacting and shaping the mortar to enhance both the appearance and the...

Brick Masonry

225
Brick masonry uses bricks as the building blocks and involves building walls from individual bricks laid in mortar. The basic building block of brick masonry is the wythe, a vertical layer of bricks with a thickness of one brick. Within a wythe, bricks can be laid in various courses or patterns, with the most common being the stretcher course, where bricks are laid with their long edge horizontal and face parallel to the wall.
For thicker walls, multiple wythes are bonded together using...

Spanning Openings in Brick Walls

In brick wall construction, supporting structures are crucial for openings like windows and doors to maintain the integrity and support the weight of the wall above. These supports include lintels, corbels, and arches, each serving specific structural purposes.
Lintels are primary supports used to span openings and can be crafted from materials such as reinforced concrete, steel-reinforced brick masonry, or simple steel angles. These are straightforward to install and are typically concealed...

Reinforced Brick Masonry01:15

Reinforced Brick Masonry

1.3K
Reinforced brick masonry is an advanced construction technique that enhances the structural integrity of brick walls by incorporating steel reinforcements. These reinforcements are either placed within the hollow cores of bricks or sandwiched between two layers of masonry, known as wythes, and are then secured in place with grout. Grout is a fluid mixture composed of Portland cement, aggregate, and water, providing the necessary bonding agent for the steel and brick.
To fortify brick walls...

Brick Classifications

213
Bricks, a fundamental component of construction, are categorized based on their application and structural characteristics into several types. These include facing bricks, building bricks, hollow bricks, paving bricks, and firebricks. Facing bricks, also referred to as face bricks, are primarily used for both structural support and visual appeal, making their appearance a crucial aspect. In contrast, building bricks are typically used in concealed sections of a structure, such as behind the...

Bricks

Bricks, a fundamental building material, are crafted from fired clay and exhibit a range of shapes, sizes, and colors. The production process starts with extracting local clay or shale, which is then crushed, ground, and screened for a fine texture. The refined material is blended with water, creating a pliable mixture that can be formed into bricks using one of three processes: soft mud, dry press, or stiff mud methods.
Soft mud bricks are shaped in molds with high moisture content and can be...

Summary
This summary is machine-generated.

Global symmetry in repeating polygon tile patterns significantly enhances perceived beauty. Integrated tilings with more emergent features and aligned elements are preferred, suggesting aesthetic appeal is linked to holistic pattern perception.

Area of Science:

  • Cognitive psychology
  • Aesthetics
  • Computational geometry

Background:

  • The aesthetic appreciation of visual patterns is influenced by underlying structural properties.
  • Previous research has explored symmetry and complexity in art and design, but systematic investigation of polygon tilings is limited.

Purpose of the Study:

  • To investigate the aesthetic characteristics of row tile patterns composed of repeating polygons.
  • To determine the relationship between local and global symmetry, emergent features, and perceived beauty in tile patterns.

Main Methods:

  • Experiment 1: Participants rated the beauty of equilateral triangle, square, and rectangular tilings with varying shifts.
  • Experiment 2: Participants rated tilings using diverse three- and four-sided polygons, analyzing symmetry and alignment.
  • Statistical analysis correlated aesthetic ratings with geometric properties like symmetry, alignment, and emergent features.

Main Results:

  • Shifts preserving global symmetry in tile patterns were rated as most beautiful.
  • Local polygon symmetry alone did not predict beauty ratings; emergent features and global symmetry were key.
  • Measures of correspondence between local and global levels, such as aligned symmetry axes and sides, positively correlated with beauty.

Conclusions:

  • Aesthetic preference for polygon tile patterns is driven by global symmetry and integration, not just local polygon properties.
  • Integrated tilings that foster gestalt formation and exploration across spatial scales are more aesthetically pleasing.
  • Findings suggest that the perception of emergent features and holistic pattern structure significantly influences aesthetic judgment.
