Standard Staircase Dimensions in Buildings

Functioning as a system of steps leading people from one level of the building to another, a staircase is a pretty complex building element. This is because staircases have particular geometry and function. Everything about this building element needs to be carefully planned because of that.

The dimensions of the steps and regulations of the heights and widths of the steps need to be carefully maintained. Not only that, you need to pay attention to the material being used as well.

In this article we will discuss the standard staircase dimensions today.

In staircase design, concrete offers great reliability in terms of load-bearing and production benefits. Geometry requirements, heat resistance and tensile strength, all can be fulfilled by using concrete. The staircases that are made of in-situ concrete can be adapted to any building plans on site.

On the other hand, precast staircases are not as flexible and can only be fitted into predefined design dimensions specific for that staircase design.

However, one advantage of using precast staircases is that they can be produced efficiently, faster and more cleanly than in-situ staircases.

It goes without saying that special attention must be paid to the basic dimensions of the stair breadth and rises. You should also need to take care of dividing the staircase with proper landings in order to enable resting places in a long climb. The number of steps without an intermediate landing should be counted in this matter.

Staircase dimensions are an important part of staircase safety. This page covers all of the important staircase measurements and a mistake to watch out for.

Staircase design has to account for the human step sizes and the comfortable distance a human foot can travel vertically.

The tread size is dictated by the average adult foot size. Though it is not necessary to fit your entire foot on the stairs, it should be kept as close as possible in order to keep it as safe as possible. The standard tread size is 10 inches minimum, or 25.4 centimeters.

Variations among Load bearing and framed structures

Superstructure is the section that situates over the ground. It comprises of walls, columns, beams, floors, roofs, doors, windows, lintels, staircases.

Types of super structures on the basis of load transmission

The super structures are categorized as follow :-

a. Load bearing structures
b. Framed structures

Load bearing structures:

Under this type of structure, the load on the structure is delivered in vertical direction through walls and then the wall transmits these loads and the self weight. These types of constructions are mostly found in residential buildings where the dimension of rooms is fewer. The residential buildings up to ground + 2 floors is constructed inexpensively with such structures.

Framed structures:

Under this type of structures, a frame work of columns and floors are constructed initially. Then the walls are erected to divide the living area.

The walls are dependent on self weight only. These types of structures are suitable when there are lots of stories in a building as well as when bigger areas should be covered free from walls.

Variations among load bearing and framed structures

Load bearing structure:

1. Construction cost is minimum
2. Best fit up to three stories
3. Walls are thicker and consequently floor area is curtailed.
4. Construction process is slow.
5. Once the construction is completed, it becomes difficult to modify the position of walls.

Frame structure:

1. The construction cost is higher
2. Ideal for different number of stories
3. Walls are thinner and as a result, more floor area can be utilized.
4. Rapid construction speed
5. If required, the location of wall may be modified.
6. Resistance to earthquake forces is good
