PTDATA
FOR WINDOWS
* Complete support for prismatic beam and
slab
properties
including:
Fully
flexible user-defined cross sections
Infinite
beam stiffness in the beam-column joint
* Extensive library of available tendon
profiles
including:
Parabolic
with user-specified high-point
locations
Compound
parabolas with user-defined
inflection
points
Single
and double-point harps with user-
specified
high-point locations
* Expanded applied load capabilities
including
uniform
loads, partial uniform loads, point
loads,
and concentrated moments.
* Internal calculation of tendon losses
including
design
for variable tendon forces considering added
tendons
and construction/stressing joints.
* Expanded modeling capabilities for
columns and
beams
including various far-end column fixity
conditions
and the capability to handle the
temporary
"bottom-column only" condition at
transfer
of prestress.
* Non-linear deflection analysis
procedures con-
sidering
cracked section properties determined
from
actual flexural tensile stresses present at
each
point along the beam or slab span.
* Optional add-on modules, of particular
use
to
bridge designers, including:
Variable
tendon force along the tendon
profile
considering friction and all
long
term losses calculated by the program
considering
12 options of interior stressing locations
and
including added tendons.
Metric
and English input and output with the ability to switch
from one
system to the other during the input and review
phases. Output can be printed either in Metric or
English
regardless
of the type of input used.
* Extremely friendly input, data
recovery, and
data
correction routines. Output can be
directed
to
a printer or to a disk file at the user's
option,
and completely reviewed on the screen
prior
to printing. Help screens are available
in each section.
* Expanded output flexibility including
stresses,
deflections,
moments, shears, and rebar requirements-
at
any number of points, selected by the
user,
along each span.
* Expanded design parameters:
25
spans
20
superimposed loads (in addition to the con-
crete
load which is automatically calculated)
in
each span.
* Direct input of lateral load moments
obtained from a,
frame
analysis program with analysis and output considering
these
moments applied in each direction and combined with
factored
live and dead load moments in the Code prescribed
alternate
combinations. The load factors may be
set by the user.
* All of the above features apply equally
to the design of Beams,
One
Way Slabs and Two Way Systems including both Flat Plates
and
Flat Slabs.
