Retrofitting Non-Structural Walls Using the Modern Wall Mesh Method

Introduction to the Importance of Non-Structural Walls

Although perimeter walls and interior partitions in buildings are not considered as lateral or gravity load-bearing elements in the initial design, they account for a major portion of the consumed materials and construction costs. During an earthquake, these components are severely affected by the lateral deformations of the main structure. Failure to properly restrain them can lead to premature damage, debris collapse, and casualties. For this reason, reinforcing and retrofitting non-structural walls has become one of the main requirements of modern seismic design codes.

The Role of Infill Walls in the Seismic Behavior of Structures

Based on earthquake engineering studies, infills affect the overall stiffness and behavior of the structure. The interaction between the concrete or steel frame and the brick or block wall can cause phenomena such as the short-column effect. To prevent these damages, implementing flexible and durable bracing systems is essential. Engineers are utilizing modern technologies to find solutions that preserve wall integrity without increasing the dead weight of the structure.

The Necessity of Transitioning from Traditional Methods to Modern Solutions

Traditional wall-restraining methods, such as heavy angle irons and field welding, in addition to being heavy, had execution weaknesses in connecting to concrete or steel structures. Stress concentration at connection points and the corrosion of steel materials reduced the useful life of these systems. Therefore, the need for a lighter, more cohesive, and highly durable engineering solution was felt, which drove the construction industry toward advanced technologies.

What is Wall Mesh and How Does It Work?

Simply put, wall mesh is a composite reinforcing grid consisting of fiberglass mesh strips combined with specialized plaster. This system serves as a suitable alternative to traditional metal wall posts. In this method, mesh strips are installed on the wall surface and covered with a layer of plaster to create an integrated system for distributing stresses caused by seismic forces.

Main Components of the Wall Mesh System

Every standard wall mesh system includes the following:

• Fiberglass mesh: The main structural core that withstands tension.
• Base plaster: The covering material that encases the mesh and ensures adhesion.
• Edge connections: Restraining profiles or angles at the top and bottom of the wall.

Technical Advantages Over Traditional Methods

Using the wall mesh system significantly reduces the building's dead load and increases execution speed. Reducing execution costs and eliminating heavy welding operations are other prominent advantages of this system that meet modern construction standards.
