Why Wind Load Matters for Temporary Structures

Temporary buildings can offer fast, flexible solutions to space problems in a wide range of industries. But to ensure safety, structural integrity and long-term performance, one factor can never be overlooked: wind load.

What is Wind Load?

Wind load refers to the pressure that wind applies to a structure. It can act horizontally, vertically or in uplift, depending on the shape, height and exposure of the building. In regions like the UK and Ireland, wind loading is particularly important due to variable and sometimes extreme weather conditions, especially in coastal and upland areas.

Wind Load in UK and Irish Building Standards

In the UK, wind loading is governed by BS EN 1991-1-4 (Eurocode 1), which outlines how buildings should be designed to withstand wind actions. This standard is also adopted in the Republic of Ireland and Northern Ireland. 

Factors such as location, terrain, height and intended use of the structure all feed into the calculation of wind loads. Local wind speed maps, such as those provided by the Met Office and Met Éireann, help define the expected wind pressures in any given area.

Lauralu ensures its structures are engineered in compliance with Eurocode standards, and site-specific wind assessments are part of the planning and design process.

Why It Matters for Temporary Structures

Unlike traditional buildings, temporary structures are often lighter and sometimes more exposed. This makes them more susceptible to wind-induced movement or damage if not properly designed. Here’s why wind load considerations are critical:

1. Safety of Personnel and Assets

A structure that isn’t designed to withstand expected wind loads can become a serious hazard. From dislodged panels to full structural failure, the consequences can include injury, equipment loss and costly downtime.

2. Compliance with Insurance and Regulations

Most insurers and local authorities require evidence that any temporary structure meets wind load requirements. Failure to comply could invalidate insurance or lead to enforcement action.

3. Durability and Structural Integrity

A well-engineered structure will not only withstand expected wind speeds but will maintain its integrity over time. This is especially important for long-term hires or semi-permanent installations.

4. Site-Specific Risk Management

In areas like the west coast of Ireland or high ground in Northern England, wind exposure is significantly higher than in sheltered inland sites. Lauralu’s team considers regional wind zone data and site topography to ensure every project is built to perform safely in its specific environment.
