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.

Introduction to Seismic Vulnerability and Non-Structural Walls
In recent decades, with the advancement of earthquake engineering and statistical analysis of damages caused by destructive earthquakes, it has become clear that a major portion of casualties and financial losses is not due to the complete collapse of the structural skeleton, but rather results from the failure of non-structural components such as partitions and peripheral walls. Although these components do not bear gravity loads, during an earthquake they undergo deformation due to inter-story drift and, lacking sufficient ductility, suffer severe cracking and brittle failure. In this regard, retrofitting non-structural walls has become an undeniable requirement in seismic design codes.
Traditional bracing systems, such as steel angles and heavy wall posts, although somewhat contributing to wall stability, have drawbacks such as creating thermal bridges, high weight, and inadequate continuity with the concrete or steel components of the structure. For this reason, design engineers have turned toward modern bracing technologies such as the wall-mesh system. To learn more about the execution details of these systems, you can refer to a reputable international source in structural engineering that has published an article on retrofitting non-structural walls with wall mesh.
The Novin Wall Mesh Department, by offering engineered solutions, has taken a major step toward securing these components. Using high-quality materials in compliance with the world's up-to-date standards guarantees the optimal performance of walls against severe earthquakes. To accurately review costs and the implementation methods of these systems, it is recommended to read the page regarding wall mesh price and non-structural wall retrofitting guide to gain a comprehensive view of the economics of retrofitting.
A Detailed Look at Appendix 6 of Standard 2800
With the publication of the fourth edition and especially the sixth appendix of Iran's Standard 2800, the design and execution regulations for non-structural walls underwent fundamental changes. The main purpose of this appendix is to regulate the seismic bracing of infills and peripheral walls to prevent their out-of-plane overturning. According to the clauses of this code, all walls with a height exceeding 1.8 meters or a length exceeding specified limits require independent reinforcement and seismic bracing. The necessity of implementing these regulations in line with retrofitting non-structural walls is a vital matter.
The code emphasizes that the connection of the wall to columns and beams should not be rigid, as it prevents the free deformation of the structure during an earthquake. The use of posts (vertical and horizontal wall posts) along with sliding connections or flexible materials is one of the common solutions. However, the heavy execution of these elements increases the dead loads of the structure itself. Here, the importance of replacing them with lighter systems becomes apparent. Also, for additional information about concrete standards and related infrastructures, reading the specialized article on retrofitting non-structural walls with wall mesh is recommended, which provides advanced engineering perspectives.
