# How To Calculate Stairs Architecture

## Understand What You Need

Summary

When calculating stairs architecture, you need to take into consideration the space available, the requirements of the project, and local building codes. It is important to have a solid understanding of what is needed as this will form the basis of the design and calculations. Measure the total height of the stairs, the head height, riser height and the goings (the flat surface covered by each step). You will also need to measure the stairwell width and floor heights. It is important to measure accurately as this will influence the calculations for the hardware and any components you may need further down the line including handrails and balustrades.

## The Stairs’ Rise, Run and Goings

When calculating stairs architecture, the rise of a stair is the vertical distance between two consecutive steps, the run is the horizontal distance between two consecutive steps, and the going is the surface covered by each step. The calculation of the rise and run should take into account local building regulations and the dimensions that are required for the particular space and project. The relationship between the rise, run and goings are important when calculating stairs architecture. For example, the size of the goings must be a fraction of the rise and the run; this combination is known as the stair pitch.

## Stair Angles and Landings

The angle at which the stair turns is an important factor when calculating stairs architecture. It is important to get the angle right to ensure that the stairs are safe and comfortable for users. Most staircases have an angle of between 35 and 42 degrees in Europe, however, this can differ between countries. If necessary, landings or platforms can be installed to create a public area on the stairs or to create a safe, comfortable space between turns. It is also important to factor in different stair angles when calculating stairs architecture. The angle of a stair should always be a quarter of a full turn.

The stair balustrade and hardware are important considerations when calculating stairs architecture. Balustrade and hardware are used to provide a secure handrail for users and to prevent any potential trips, slips and falls. It is important to get the dimensions of the balustrade and hardware correct to meet local building regulations. The hardware form part of the structure of the staircase and must be securely and safely installed. There are a range of balustrade and hardware options available so it is important to consider the aesthetics of the staircase when selecting the components.

## Costs and Budgeting

When calculating stairs architecture, it is important to consider the costs of the project. It is essential to consider materials, labour and the components needed to construct the staircase, such as balustrade and hardware. Depending on the type of staircase and the design, the costs can vary significantly. It is important to ensure that the budget is realistic and can cover the total cost of the project.

## Consult an Expert

Calculating stairs architecture can be a complex process and it is important to consult an expert when planning the project. An architect or building designer will be able to advise on the best type of staircase for the space and provide guidance on any regulations or requirements that may be applicable. They will also be able to assist in calculating the rise, run, angle and hardware options. Consulting an expert is a good way to ensure that the staircase is designed correctly and safely.

## Drafting the Stairs

Once the calculations have been made it is important to draft the staircase accurately. Drafting by hand or computer is a necessary step in the process of calculating stairs architecture. All the components and measurements needed for the project must be accurately plotted to ensure that the project is a success. It is essential to take into account all the calculations made to ensure that the stairwell meets local building regulations and is safe and secure.

## Other Considerations When Calculating Stairs Architecture

When calculating stairs architecture, there are a range of other considerations that should be taken into account. These include the type of material used to build the stairs, whether it is a straight or winding staircase, how the staircase is lit, what type of railing is used, and any additional nodes that the staircase may have. It is important to consider all of these elements when calculating stairs architecture to ensure a successful project.

## Ensuring Safety When Calculating Stairs Architecture

An important factor to consider when calculating stairs architecture is safety. It is important to ensure that the correct calculations are made and that all components are safely installed. Local building codes should be taken into consideration when designing the staircase and all components must meet the relevant standards according to the regulations. It is also important to ensure that the staircase is well-lit and has a secure balustrade and handrail for users to grasp.

## Planning For the Future When Calculating Stairs Architecture

When planning a project, it is important to consider future needs. Calculating stairs architecture involves more than a one-time project; it should be a long-term plan. Consider any potential changes to the space or regulations in the future and plan accordingly. For example, an L-shaped or spiral staircase might not be able to accommodate additional flights of stairs in the future, while a straight or switchback staircase might be more suitable.

## Calculating Load and Stress When Planning Stairs Architecture

When calculating stairs architecture it is important to consider the load and stress on the structure. The calculation of the load should take into account the static and dynamic forces applied, such as those from human traffic, objects and any potential wind loads. An engineer should be consulted to calculate the stresses that the construction will be exposed to, to ensure the design is safe and secure.

## Understanding Potentially Complex Aspects of Calculating Stairs Architecture

There are several potentially complex aspects of calculating stairs architecture. This includes understanding the relationship between the rise, run and goings, ensuring safety, planning for future needs and calculating the load and stress on the structure. It is important to accurately measure the area and consult an expert to ensure a successful project.
