What factors affect the stability of a wall?
Foundation, lateral loads such as wind and earthquake loads, temperature effects, load eccentricity, and changes in moisture , are a few factors that determine the stability of a wall. Eccentric loads that do not act on the centre of the thickness of the wall tend to deform and overturn walls. Protecting the wall against such loads like wind requires stiffening up the height of the wall and using intersections to prevent deformations. Thus, stability involves resistance against lateral forces, causing overturning and excessive slenderness, causing buckling.

Functional Specification: Its Importance
Several considerations will crowd your mind as you plan your project. You will need to plan key aspects like human resources, methodologies, technology stack, tools, etc. You might face roadblocks though if you don’t manage these requirements efficiently.
The Various Kinds of System Requirements
Functional requirements aren’t the only kinds of system requirements. You will also need to define non-functional requirements (NFRs). Let’s briefly understand how they differ.
An Introduction to a Functional Specification Document
A functional specification document (FSD) carries plenty of importance. You create this document to describe the functional requirements of your software application.
What are Functional Requirements and Their use Cases?
You might have also come across the term “use cases” often in the context of functional requirements. Do they mean the same thing, or, are they mutually exclusive? Let’s clarify this.
Common Examples of Functional Requirements
How you document functional requirements depends on your project. You need to provide sufficient details though. Take a look at the following examples of functional requirements, which makes the importance of details obvious:
How to Create an Effective FSD (Functional Specifications Document)?

Durability of walls is determined by frequency and the amount of work that is required to make the wall meet the minimum requirements functionally and aesthetically acceptable. Functional requirements might include the wall capability to resist rain and thermal properties.
What causes a wall to be unstable?
Overturning tendency of the wall is due to loads that are not acting on the center of the wall like loads from roofs and floors and lateral loads. If both lateral loads and eccentric loads increases wall deformation is increasing and thus the wall will be unstable. Building codes provide recommendation for wall height and width to prevent instability resulted from loads. Moreover, horizontal restrictions such as tie between walls and roofs and intersection between walls and piers prevent deformation due to lateral loads. Furthermore, walls with irregular configurations as shown in Figure-1 are more stable than regular straight walls because buttress actions come into effect in the former.
How thick should foundation walls be?
Damp-proof layer with a thickness of 150 mm can be employed above ground level for all foundation walls. This could prevent water absorption from the ground which could have a detrimental effect if it is not dealt with properly. The water that might penetrate walls from the rainfall depends on many factors such as quality of materials and the way of assembling those materials together and prevailing winds. There are several solutions for situations such as using greater thickness for walls, construction brick, stone, or block walls in two skins with 50 mm cavity between them, protecting wall outer face by cladding or plastering, and utilizing a glass sheet as a curtain wall. Moreover, environmental features such as hills, trees, or other constructed buildings around should be taken into consideration in determining proper solutions, because these can change severity of exposure conditions to prevailing winds that direct rain on the walls
