The STRAP steel design postprocessor is unique
in its wide range of options and in the flexibility it gives you in the design process.
In addition to the design of regular steel sections, the program enables the design of
cold-formed (light gauge) sections and composite sections. The program also includes a unique module that performs an optimization of the structure for
sway and drift.
Some examples for 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 at any direction and location of the
beam.
-
In addition to all the standard section tables contained in the program,
you can generate your own special sections using a special module in the
program that calculates all the required properties for the steel design
for given section dimensions.
-
You may confine the section selection to any defined subgroup of the steel
tables or by specifying the limits of the sections dimensions.
-
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 in several points in
unsymmetrical sections (e.g. T, L, U etc) accounting for the correct signs of the stresses.
-
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
