Stairs
General
notes
Stairs are
the part of 3D Model. The program generates 3D flights of stair (separate files
in folder Stairs
of current project) and then inserts flights in 3D model of entire structure. There
are no restrictions in number of stairs used in project, as well as each stair
can contain any number of flights. Your project can be just stairs (without
structural members) or structural + stairs or just structural.
Getting
started
Before you
start stair’s input you should have grid nodes and levels in database. Play

Main
Stairs Form
All
operations in development of stairs can be performed from Stairs Main Form (press the button Stairs
in Main Form of SolidStructural):
Stairs
Input
To add
stairs in database press the button Stairs Input in Stairs Main Form
In opened
form enter name of stair
In the top
part of the form you can setup parameters of stair such as carrier angle
material, concrete thickness etc. To add new stair press Duplicate STAIR button
, give the
name of new stair and assign typical parameters for stair.
To navigate
between stairs use buttons at the very bottom of the form.
Select
Start and End levels; enter number of Risers, select stringer material
Next step:
enter stair’s working points - nodes (e.g. select A4 - press TAB - enter B4 -
press TAB and so on) and types of Stair’s stringer start and end details
Remarks
Working point for
stair:
-
Channel stringer:
intersection of nosing line with stringer (back of channel)
-
Tubes: intersection of
nosing line with center line of flange
NS-FS stringer – (see
picture above): top of flight on the right, bottom – on the left
Experiment
with input in order to become comfortable using this form. What can help?
- In order to facilitate input
use DUPLICATE record button for both flights and stairs.
- Use beams as part of stair
stringer or platform. Advantage of this combined method: you can add clip
angles and other connections to connect stingers or back channels to
supporting members and as the result – more complete drawings.
- If you are not sure what type
of connection to choose, then do minimum input; print Stairs report
(button Selected
Stairs Report in Stairs main form); generate 3D stair (button Generate
Selected stairs (3D)). After that you can preview flight or
stair (open the corresponding file in Stair folder of your current project).
Finally you can create 3D model and produce Elevation View, where you can define
all parameters needed in Stair Input form.
- You have at your disposal Stairs Add
Material form (accessed from Stairs main form), where you can
add channel to stringer: select flight and define the location and
material of channel.
- Read control Tip Texts
and
status bar comments on the bottom of the form (press cursor in the
corresponding field)

Rails
Click on Rails Input
button in Stairs main form. Select appropriate type for each end of rail and
enter parameters of rail. Examples are shown in table below. You can build more
complicated railing system, containing several rails: duplicate record, select
different height or offset distances and other parameters.

How to
produce elevation of stair?
Create 3D
model with stairs. Click on ‘Elev. View X or Y sect.’ button in main form.
Select appropriate grid line and distances and generate elevation view Look at
the examples of stair drawings and 3D models produced with SolidStructural at:
http://www.nyacad.com/SS07Drawings.htm
How to
produce stair plan?
Create 3D
model with stairs. Generate plan view (use the corresponding button in SolidStructural
Main form). Go to main Stairs form; press the button ‘Draw Plans’. Next you can
transfer plans using Copy with base point (use 0,0 as
a base point) command to plan view drawing or insert it as a block.
