Reviewing the Impact of Wall Dimensions on Wall Mesh Calculation Results

An Introduction to the Importance of Geometry in Building Engineering

The design and execution of non-structural walls has always been one of the significant challenges in civil engineering. Infill walls and partitions exhibit complex behavior under lateral forces caused by earthquakes. Meanwhile, wall mesh calculations, as one of the modern reinforcement methods, require high precision in determining geometric parameters. The length and height of the wall directly affect how stresses are distributed.

When it comes to seismic retrofitting, the geometric dimensions of the wall are the primary determinant of the lateral force demand. Design engineers must accurately measure the free length and effective height of the wall before taking any action. Do not forget that any mismatch between the executed dimensions and engineering drawings can lead to calculation errors throughout the entire execution process.

Based on international standards such as retrofitting non-structural walls with wall mesh, the aspect ratio of length to height is highly critical in the behavior of fiberglass mesh sheets. If this ratio exceeds the allowable limit, the probability of stress concentration in the corners increases.

To better understand the behavior of clay and block walls in various dimensions, reading the specialized article How are wall mesh calculations performed for block and clay walls? will be very helpful and provide you with a better perspective.

The Determining Role of Free Length in Element Analysis

Wall length is one of the key components in determining the spacing of wall mesh strips. In wall mesh calculations, the greater the length of the wall, the higher the bending moment resulting from out-of-plane lateral loads. This phenomenon directly affects the plaster thickness and the type of mesh used.

For a more precise analysis of the formulas, it is suggested to read the comprehensive article A Detailed Review of Formulas and Relations in Wall Mesh Calculations to become familiar with the mathematical relationships governing different lengths. The general comparison of the effect of wall length on design parameters is presented in the table below:

Wall Length	Mesh Strip Spacing	Recommended Mesh Type
Less than 3 meters	Maximum standard spacing	E-Glass mesh
Between 3 and 5 meters	Optimal medium spacing	C-Glass mesh
More than 5 meters	Tightly spaced	Resistant Zr-Glass mesh

Additionally, site environmental conditions such as humidity also affect the final execution quality, about which you can obtain supplementary information in the article Examining the Impact of Environmental Humidity on the Final Quality of Wall Mesh Plaster.
