Thermal Insulation in Masonry Walls01:22

Thermal Insulation in Masonry Walls

473
In hot, dry climates, the thermal mass of masonry walls can be beneficial, absorbing heat during the day and releasing it at night, thereby stabilizing indoor temperatures. However, in most other climates, additional insulation is necessary to enhance thermal resistance.
External insulation can be applied using an Exterior Insulation and Finish System (EIFS), which involves affixing panels of plastic foam to the wall and covering them with a polymeric stucco reinforced with glass fiber mesh....

Insulation Coordination01:23

Insulation Coordination

550
Insulation coordination is the process of matching electric equipment's insulation strength with protective device characteristics to protect the equipment against expected overvoltages. This selection is based on engineering judgment and cost. Equipment can generally withstand short-duration high transient overvoltages, but repeated tests with identical waveforms can yield inconsistent results. As a result, standard impulse voltage waveforms are used for testing, defined by specific times...

Thermal expansion and Thermal stress: Problem Solving

2.1K
San Francisco's Golden Gate Bridge is exposed to temperatures ranging from -15 °C to 40 °C. At its coldest, the main span of the bridge is 1275 m long. Assuming that the bridge is made entirely of steel, what is the change in its length between these temperatures?
To solve the problem, first, identify the known and unknown quantities. The initial length (L) of the bridge is 1275 m, the coefficient of linear expansion (α) for steel is 12 x 10-6/°C, and the change in temperature (ΔT) is 55...

Masonry in Cold and Hot Weather Conditions01:21

Masonry in Cold and Hot Weather Conditions

326
In cold weather, masonry construction requires specific precautions to ensure mortar does not freeze before curing, as this can significantly weaken its strength and watertightness. Mortar temperature should be maintained between 60°F and 80°F to support proper hydration and curing. Below 40°F, mortar water must be heated, but should not exceed 120°F as high temperatures can reduce mortar's compressive and bond strength.
Other key practices include keeping masonry units...

Conduction, Convection and Radiation: Problem Solving

2.2K
There are three methods by which heat transfer can take place: conduction, convection, and radiation. Each method has unique and interesting characteristics, but all three have two things in common: they transfer heat solely because of a temperature difference; and the greater the temperature difference, the faster the heat transfer.
In order to solve a problem related to heat transfer, first of all, the situation needs to be examined to determine the type of heat transfer involved. This could...

Masonry Curtain Walls01:20

Masonry Curtain Walls

1.7K
Masonry curtain walls employ brick or stone veneers supported by the building's structure to form an external cladding system that is both aesthetically appealing and functional. These walls are erected through two principal techniques, first by traditional layering of masonry units and second by using prefabricated panels. Traditional construction relies on steel shelf angles attached to the spandrel beam for support, with high-bond mortars ensuring secure attachment of masonry veneer...

  • Measurement of material density, thermal conductivity, compressive stress, and bending strength.
  • Comparative analysis between corrugated and non-corrugated textile-based insulation materials.

    • Main Results:

    • Corrugated textile sheets yielded thermal insulation materials with densities from 51.9 to 76.8 kg/m³ and thermal conductivity from 0.0385 to 0.0535 W/(m·K).
    • Wave size and adhesive layer significantly influenced density and thermal conductivity.
    • Materials from finely corrugated sheets exhibited superior compressive stress (17.3 kPa) and bending strength (-157 kPa) compared to non-corrugated materials (0.686 kPa and 9.90 kPa, respectively).

    Conclusions:

    • Corrugation of textile sheets enhances mechanical and deformation properties of thermal insulation materials without compromising density or thermal conductivity.
    • Textile-based corrugated materials offer a promising alternative for building insulation, demonstrating improved performance characteristics.
    • Materials engineering principles, specifically corrugation, can significantly enhance the functional attributes of insulation materials.
