A method applicable to the design of unbraced multi-storey steel frames to
specified limits on horizontal sway deflection is presented. This method of
design is the extension and combination of the work by Wood and Roberts [1]
and Anderson and Islam [2]. Only simple calculations are required by the
method and its application is illustrated by worked examples. Regular and nonregular
steel frames are considered . The method proposed is suitable for the
design of unbraced multi-storey frames if the choice of sections is controlled by
sway deflection.
