Masonry Cavity Walls01:26

Masonry Cavity Walls

1.1K
Cavity walls feature a hollow space between the outer and inner wythes, connected only by corrosion-resistant metal ties. When water seeps through the outer wythe, it descends within this cavity, intercepted by flashing and eventually exiting through weep holes. To enhance moisture resistance, the inner wythe's cavity side often receives damp-proofing, doubling as an air barrier. The cavity can also house insulation to mitigate heat transfer.

Cavity Drainage and Flashings in Masonry walls

116
Typically, a cavity wall consists of two wythes separated by a gap of at least 2 inches, which may contain insulation while still maintaining a minimum clear space of 1 inch to facilitate adequate drainage. Advanced methods like the insertion of a continuous drainage mat can further reduce this space while ensuring effective moisture expulsion.
Weep holes, strategically placed at the base of the cavity, are critical for draining accumulated water. These openings are created by leaving head...

Posttensioned Masonry Walls01:15

Posttensioned Masonry Walls

182

Post-tensioned masonry walls use high-strength steel rods or flexible tendons to enhance the strength and efficiency of masonry structures. These elements are securely anchored to the foundation and extend vertically either within the cores of the masonry units or between the masonry wythes. The construction process involves building the wall with these tensioning elements in place and allowing the mortar to fully cure.
Following the curing process, the tensioning begins. Steel rods are...

Expansion and Contraction in Masonry Walls01:19

Expansion and Contraction in Masonry Walls

994
Masonry walls are subject to slight expansion and contraction due to variations in temperature and moisture. Thermal movement in masonry is relatively straightforward to measure and plan for. On the other hand, moisture movement poses more of a challenge. New clay masonry units typically absorb water and expand over time under normal environmental conditions. Conversely, new concrete masonry units tend to shrink as they lose the excess moisture acquired during their production process.

Masonry Curtain Walls

1.1K
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...

Thermal Insulation in Masonry Walls01:22

Thermal Insulation in Masonry Walls

156
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....

Area of Science:

  • Otolaryngology
  • Middle Ear Surgery
  • Audiology

Background:

  • Attic retraction pockets are a common condition affecting the middle ear.
  • Accurate classification is crucial for effective management and predicting outcomes.

Purpose of the Study:

  • To introduce and validate a novel grading system for attic retraction pockets.
  • To correlate this grading system with surgical management and long-term outcomes.

Main Methods:

  • A new attic retraction pocket grade was developed based on invasion and erosion.
  • Management strategies (surgical vs. non-surgical) were applied to 200 ears based on the grade.
  • Outcomes including tympanic membrane condition, middle ear status, and air-bone gap were recorded over 36-240 months.

Main Results:

  • Non-surgical management was used for 44 grade I ears; surgical management for 156 grade II-V ears.
  • A low complication rate of 1% (1 reformation, 1 adhesive otitis media) was observed.
  • Significant improvement in air-bone gap was noted (p < 0.05).
  • An earlier cohort (50 grade IV ears) using atticotomy showed a 68% recurrence/cholesteatoma rate, which was resolved with revision surgery.

Conclusions:

  • The proposed attic retraction pocket grade effectively guides management.
  • Reconstruction based on this grading system ensures long-term stability of the tympanic membrane, middle ear, and hearing.
