Disadvantages Of Load Bearing Masonry Construction: Poor Performance In Earthquakes, High Labor Requirements, Slow Construction Process, Environmental Impact, Cost, Thermal Insulation
While load-bearing masonry construction has its advantages, it also comes with certain disadvantages that need to be considered in the construction process.
One of the primary concerns is the poor performance of masonry walls during earthquakes. Masonry, by itself, has limited ability to absorb and dissipate seismic forces, making it susceptible to cracking and failure under severe shaking. This drawback can be mitigated through the inclusion of appropriate reinforcement measures or the use of alternative construction techniques in earthquake-prone regions.
Another disadvantage is the high labor requirements associated with masonry construction. Skilled masons are needed for precise placement of units, mortar application, and ensuring proper alignment and levelness of walls. The labor-intensive nature of masonry work contributes to increased construction costs and longer project durations.
Additionally, the construction process for load-bearing masonry can be relatively slow compared to other techniques. The time-consuming nature is attributed to the need for mortar curing and the sequential construction of walls, which can impact project schedules.
Load-bearing masonry construction can also have environmental implications. The production of masonry units often requires the extraction and processing of raw materials, resulting in the consumption of natural resources and energy. Moreover, the limited thermal insulation properties of masonry walls can lead to increased energy consumption for heating and cooling, impacting the overall sustainability of buildings.
Lastly, the cost of masonry units can be prohibitive, especially for high-quality materials like stone or special-shaped bricks. This cost factor needs to be factored into the project budget, considering the desired aesthetic and functional requirements.
