The STRAP
steel design module is unique in the wide range of design options and flexibility that it provides.
In addition to designing regular steel sections, the program also designs
cold-formed (light gauge) and composite sections. The program also includes a unique module that performs an optimization of the structure for
sway and drift.
A module for connection design is also available.
Some examples of the program features:
-
Unlike other programs, in STRAP you
do not have to define the buckling lengths for the members:
- A beam consisting of several STRAP
members may be combined to a single beam for the design.
- Intermediate supports may be
defined in any direction, either flange and at any
location along the beam.
-
In addition to all the standard
section tables contained in the program, you can create your
own custom sections using a special module that calculates
all the properties required for the steel design
from the section dimensions.
-
You may limit the section selection
to any type or subgroup of the steel tables and
you may specify min/max section
dimension limits for any member.
-
Detailed calculations with reference
to all Code formulae may be displayed and printed for
selected beams.
-
Members may be displayed in various
colors according to their efficiency ratio.
- The model may consist of hot rolled, light gauge and composite sections, or any combination of them.
-
Many types of compound sections may
be designed and checked. The program may select the most
economical section from a group of compound sections.
-
Design of single angles about
principal axes. The program checks the stresses at several
points in unsymmetrical sections (e.g. T, L, U etc)
- Calculation of torsion and warping stresses.
- The program supports the following
codes for hot rolled and composite sections:
AISC - ASD & LRFD, UBC, British Standard 5950,Eurocode 3, AASHTO - ASD & LRFD and Canadian CAN/CSA, S16.1
- The program supports the following codes for cold formed sections:
AISI, ASD & LRFD
, CSA
