UDL= ( Weight of all materials, tools & equipment and personnel on scaffolding) / (Total area of scaffold decking) The live load of scaffolding, commonly known as the uniformly distributed load ( UDL ) is calculated using this formula: How to calculate the live load of scaffolding The safety factor in the UK is typically 2.0, although it may vary depending on the specific conditions and regulations. Safety Factor is a factor that accounts for the uncertainties in the load.Weight of Scaffold is the weight of all the scaffold components and any tools or materials that will be placed on the scaffold.Maximum Intended Load is the total weight of workers, tools, and materials placed on the scaffold at any one time.Scaffold Weight Capacity is the maximum load that the scaffold can hold, as specified by the manufacturer and marked on the scaffold.SWL = (Scaffold Weight Capacity) / (Maximum Intended Load + Weight of Scaffold) x Safety Factor The formula for calculating the SWL is as follows: This means that the maximum load that scaffolding supports shouldn’t be more than half its load capacity. In the UK, a safety factor of at least 2 is applied to the scaffold load capacity to ensure that it can safely support any intended load. When calculating the safe working load( SWL) you should consider the scaffold weight capacity, maximum intended load, scaffold weight and the safety factor. How to calculate the safe working load of scaffolding Other factors you should account for when determining the safe working load for scaffolding include the speed of the wind and seismic activity ( probably not relevant in UK ). How level the ground is, is another crucial thing to consider because it can significantly impact the load capacity of scaffolding. Here the weight includes that of the scaffolding components and any materials or tools placed on the scaffold. The weight of the scaffold is another crucial factor that needs to be considered. This is basically the total weight of the tools, workers and materials that are to be placed on the scaffold at any one time. Secondly, you should also consider the maximum intended load. The manufacturer should clearly indicate the load capacity rating on the scaffold. Usually, the weight of the scaffold plus the maximum intended load is lower than the rated capacity. There are several things to consider when determining the load capacity of a scaffold and one of them is the load capacity rating as specified by the manufacturer. This includes the platform, frames, cross braces, guardrails, and any tools or materials that will be placed on the scaffold.įactors to consider when determining the scaffold load capacity The weight of the scaffold is the weight of all the scaffold components.Maximum Intended Load is the total weight of tools, workers, and materials that will be placed on the scaffold at any one time.This is determined by the manufacturer and it’s marked on the scaffold. Scaffold Weight Capacity refers to the maximum load that the scaffold can hold.Load Capacity = (Scaffold Weight Capacity) / (Maximum Intended Load + Weight of Scaffold) The formula for calculating the scaffold load capacity is as follows: Here’s the formula used to calculate the live load and other things you need to consider. Being able to calculate the load capacity of scaffolding is crucial because it helps you avoid overloading the scaffold. The load capacity of scaffolding is calculated by dividing the scaffold weight capacity by the sum of the maximum intended load and the weight of the scaffold.
