How to execute retrofitting of non-structural walls at the lowest cost?

Why is protecting infills and non-structural walls important?

In natural disasters and recent earthquakes, one of the most vulnerable points in buildings has been non-structural walls and infills. The destruction of these components not only causes heavy financial losses, but also endangers the lives of residents due to the possibility of falling debris. Therefore, structural engineers and designers are always looking for efficient solutions to seismically restrain these components. For more familiarity with specialized regulations, you can refer to the article complete design and execution of non-structural wall retrofitting with wall mesh.

Traditional methods such as the use of metal wall posts and angle brackets, in addition to high weight and exorbitant costs, require precise welding and time-consuming processes. Today, with the advancement of technology in the construction industry, modern solutions have replaced old methods, among which we can mention the non-structural wall retrofitting system offered by brands such as Tarsazeh to the market. These systems, without the need for heavy metal structures, show much better performance against lateral loads.

Main goals in wall safety

• Preventing wall overturning in out-of-plane directions
• Improving ductility and integrity of non-structural components
• Reducing the dead load of the structure compared to traditional metal methods
• Full compliance with the requirements of Standard 2800 and the sixth appendix

Based on studies published in the reputable database non-structural wall retrofitting with wall mesh, the use of reinforcing composite systems plays a significant role in reducing secondary earthquake damages. For this reason, choosing standard materials is of special importance.

What is wall mesh and how does it work?

The Wall Mesh system is an engineered technology based on fiberglass mesh and mineral plasters, known as a modern alternative to metal wall posts. In this system, non-structural wall retrofitting is done by adhering fiberglass grids to the wall surface and covering them with a layer of gypsum or cement plaster. This integrated structure homogeneously distributes earthquake-induced stresses across the wall surface.

Key components of the Tarsazeh wall mesh system

• Tarsazeh E-Glass fiberglass mesh: Suitable for conventional construction projects with high tensile strength
• Tarsazeh C-Glass fiberglass mesh: Having favorable chemical stability against alkaline environments
• Tarsazeh Zr-Glass fiberglass mesh: Containing zirconia, resistant to highly alkaline and cementitious environments
• Tarsazeh gypsum and cement-based plaster: For covering and creating optimal adhesion with the fiber surface
