Stairs

|
6 different types of stairs can be structurally analyzed and their reinforcements can be calculated depending upon the applicable concrete and reinforcing steel classes. After completion of structural analysis, the appropriate reports are issued, and the relevant details, plans, sections and elevation views are prepared automatically.
Stairs Type 1 is a cantilever stairs, which is supported at one side to a bearing wall like a console. At such types of stairs, the individual steps are assumed as to be fix supported like a console to the carrying wall at one side.
|
 |
 |
|
Stairs Type 2 is a box stairs, which is supported at two sides to two bearing wall like a simple beam. At such types of stairs, the individual steps are assumed as to be simple supported like a simple beam to the carrying walls at two sides.

Stairs Type 3 is a 2-flight quarter-turn stairs with landing, at which the lending is supported at three outside edges to the carrying walls around the stairs. At such types of stairs, the floor landing (landing pace) at the story floor level is fix supported to the carrying walls, and the half-space landing at the mezzanine (half story) level is simpled supported to the beam of the half-space landing. The influence of the quarter-turn system, which is attributable to the fact that the flight and the landing slab of the stairs do not run in same direction, is assumed as half effective.

|
Stairs Type 4 is a 2-flight turn stairs with landing, at which both the lending and the stairs are supported at the inside edges to a core consisting of shear walls. At such types of stair, the flight and of the landing is fix supported to the core at one side, while the other side of the flight and landing is cantilever. |
 |
 |
|
Stairs Type 5 is a screw (spiral, winding) stairs with open hollow-nevel without half-space landing, which is supported at both ends as helix shaped spatial frame. The stairs is supported from down to up only at both ends. The bearing at both ends is in the form of fix supporting. |
 |
 |
|
Stairs Type 6 is a 2-flight turn stairs with landing, which is supported at both ends and the landing and straight flight of which is a space frame. The stairs is supported from down to above only at both ends. The landing is cantilever. The bearing at both ends is in the form of fix supporting. |
