STDESIGN V3.1 Pro - Slab punching check
Decon® is proud to announce the release of the latest update to its FREE Studrail® design software, STDESIGN V3.1.
STDESIGN V3.1 contains many enhancements and upgrades, while improving its already user-friendly functionality, intuitive interface and efficiency for verifiable output.
STDESIGN V3.1 is the final version of the software that was previously available as BETA V3.0.x. There were no significant updates between V3.0.x and V3.1; most of the changes were simply resolving issues that came up due to specific unusual geometry and load combinations. The main calculation subroutines are otherwise unchanged.
This is a complete upgrade from STDESIGN V1.3 and contains the following significant changes (as well as many other upgrades:
· Update to ACI 318-05, which has identical Studrail design criteria as ACI 318-02.
· Update to ACI 421.1R-99, which allows the designer to create a more efficient Studrail design. These provisions have now been included in ACI 318-08.
· Update to CSA A23.3-04.
· Inclusion of the ductility design requirement of IBC 2003.
· Round columns can now be designed as round columns rather than by using an equivalent square column.
· We have adopted the gamma-v equations from Figure B2 of ACI 421.1R-99.
· Openings can be input either in the traditional manner (angles of lines from the column centroid and tangent to the openings) or by specifying the size and location of each opening.
· Inclusion of basic context-sensitive help.
· Real-time graphic showing the Studrail design as input fields are entered.
We will continue to update this software and would like to receive feedback from users on what they like about the software and what updates they would like to see. Some of the ongoing items we are reviewing are:
· The graphic showing the Studrail® design should position the Studrails® correctly around openings. Currently, the design graphic may show Studrails® through the openings.
· Section 21.11.5 of ACI 318-05 gives two methods of determining the required Studrails® due to the combination of gravity loads and high drift. We currently include the IBC-03 requirements, which are similar to Section 21.11.5b. Should the provisions given in Section 21.11.5a also be included? To use these provisions, the user would be required to provide more input for each connection.
· We will create a subroutine that will review all of the design output for a given project and consolidate the Studrail® designs to minimize the number of different Studrail® sizes, without creating an increase in cost. There could be substantial labor savings, as well as a reduction in the chance of installation errors, by consolidating the Studrail® sizes.
