ON ENTERING a building, almost the first thing that meets
the eye is the staircase and unconsciously it is made to serve
as an indicator of the quality of the architecture. If the design
is poor or the construction faulty, this flaw immediately gives
the visitor a bad impression of the whole building. Furthermore,
stairbuilding is a rather difficult subject and the principles
involved are very little understood, which is evidenced by
the fact that the layouts as furnished by architects in their
plans are often improperly done.
Probably more mistakes occur in connection with the stairway
of a building than with any other construction feature. It
is with the idea, therefore, of giving a complete though simple
presentation of the construction methods as 'applied to standard
design of staircases, that this book has been prepared.
The article discusses straight and winding stairs, stairs
with well hole, layouts for curved turns, the proper proportions
of rise and width of tread, the design of hand railings and many
other problems, the solution of which will be found very useful.
Coupled with this article is a most instructive section on
the Steel Square, containing many applications of this useful
instrument to roof and other types of construction.
