     BEAMER  is  computer  solution of five   commonly  occurring
structural  beam  types.   BEAMER   will solve  for  the  support
reactions,  bending  moments,  stress and deflection values at  a
specified tabulation interval along a beam.

     The five beam types that BEAMER can solve are:

     1. Fixed-Fixed beam .
     2. Fixed-Pinned beam.
     3. Cantilevered beam.
     4. Pinned-Pinned beam.
     5. Pinned-Pinned-Pinned beam.

     In  case 2 the pinned support may be located at any position
along  the beam.  If the support is located at the fixed end  the
beam is cantilevered.

     In  case  4 one of the pinned supports  is  relocatable, the
other is set at the end of the beam.

     In case 5 two of the pinned supports are set at both ends of
the beam the third is relocatable along the span of the beam.

     In all cases a distributed load may be placed anywhere along
the beam.  A concentrated load may also be placed on the beam  in
the  following manner:  For a concentrated load of 2000 lbs.  the
length  of  the load (C) shall be set to 0.1  ft.  and  the  load
intensity (Q) shall be set to 20,000 lbs./ft.  (20,000 lbs/ft.  *
.1 ft.  = 2000 lb.  concentrated load). Or Q=200,000 lbs./ft. and
C=.01 ft. would also give the same concentrated load effect.

     Only one load may be placed on a beam at a time. BEAMER will
figure the moment,  deflection and support reaction values for  a
single  load  condition,  BEAMER then displays these  values  and
retains them in an array.  BEAMER will then ask if you would like
to  super-impose another load on this beam.  If answered  YES the
operator is prompted for more load data. BEAMER  then figures the
moment,  deflection, and support reaction values for the new load
condition  independant  of the previous  load  conditions.  These
newly  fiqured values are again displayed to the  operator.  When
the operator answers NO to the super-impose question BEAMER  will
display the combined effect of all the load conditions.
.pa
     The  programs on the enclosed disk are compilied BASIC code.
The  program  BEAMER links to a run-time  module  called  BASRUN.
BASRUN  must  reside  on the same disks as  BEAMER.  The  program
BEAMER2  does  not need the run-time module  BASRUN.  Notice  the
difference in size of BEAMER and BEAMER2. In BEAMER2 the routines
from  the run-time module have been incorporated in  the  BEAMER2
file making it a much larger file.  BEAMER and BEAMER2 have  been
compiled from the same source program.

     The  BASIC  source code has not been included on  the  disk.
BEAMER  uses  many  highly complex  mathematical  algorhythms  to
obtain  the  beam  solutions.  If the source  code  were  changed
improperly   the  solutions   would  not  be  correct  ultimately
resulting   in structural failures.  US Software  Co.  will  only
release  the  source code to qualified Civil Engineers to  assure
the integrity of the source code.  Please contact US Software Co.
if you which to change or enhance the BEAMER program.

     Data from the BEAMER program can be printed to your printer.
If you wish a hard copy of the data you can do one of two things.
One,  Toggle  your  printer on by holding the <CONTROL> key  down
while  simultaneously  pressing the <P>  key  (^P).  This  action
should  be done before you run BEAMER.  It will cause your system
to  send  all screen print to the printer.  A system  error  will
occur  if  your printer is not in the  ready  state.  The  BEAMER
program  does  not incorporate the BASIC  LPRINT  statement.  The
program  entitled BEAMERLP on the disk does use the BASIC  LPRINT
statements.  If  you run BEAMERLP you do not need to toggle  your
printer on (^P) from the system level, just ready your printer.
