This document describes several new features and improvements in the latest version of STRUDS software. Some key points include: 1) A new graphical interface with unlimited redo-undo options for geometry creation. 2) The ability to move slabs, elements, and nodes during modeling. 3) Using the Complete Quadratic Combination method for modal combinations in generation of earthquake loads. 4) Consideration of column offset and wide column effects in the design of beams and calculation of moments and shear forces.

2. New GUI with some new features New Feature
New
Graphical
Interface with
unlimited Redo –

ease in
geometry
creation.
Option to
move slabs,
elements, nodes
during
modeling.

3. C.Q.C Method for generation of EQ. loads New Feature
using Response spectrum.
Complete Quadratic Combination method
used for modal combinations.

4. Column offset and wide column effect New Feature
Using this option the support width effect is considered at preprocessor and
accordingly the span moments and end moments of beams are calculated.
Since the moments and shear forces are calculated at the face of columns it
results in economical design. Details given on next page.

5. Column offset and wide column effect
• When two members such as a beam and column are connected at a point,
there is some overlap of the cross-sections. In many structures, the
dimensions of the members are large, and the length of the overlap can be
a significant fraction of the total length of the frame element. Defining end
length offsets along the length of frame elements can account for these
finite dimensions of structural elements.
• When a line object is used to model a frame section, the line object is
assumed to be located at the centroid of the frame section. Thus, when line
objects (frame sections) intersect in a model, it means that the centroids of
the associated frame objects intersect. In a real structure, that is not always
the case. For example, it is not unusual for one or more floor beams in a
building to frame eccentrically into a column.

10. Saving default selected bar diameters for all Improvement
components
Now user will be able to set his preferences for bar diameters for
various components separately.
Once you save the selected bar diameters for any structural
component that will be reflected in all project unless you change it
again.

11. In slab design break design option is given New Feature
Option to break design or change
the parameters like area of steel
or thickness etc. are given in
single dialog box for the ease in
designing any project.

12. Beam group-wise report in HTML format New Feature
Beam group schedule is added in HTML format.

13. Recent open files list in file menu New Feature
List of last
four files opened
in the software
is given to open
the file from the
same path.

14. Window selection option in column shapes New Feature
and sizes for multiple columns
In column orient view for
multiple selection of columns
window selection option is
given for changing shape
and sizes of column to save
time in modeling.

15. Improvement in 3D display Improvement
Improvements in 3D View for better display and understanding of
geometry.

16. Import and Export of ETABS file in STRUDS Improvement
If you have ETABS file
and it’s analysis file you
can import the same in
STRUDS.
You can export STRUDS
file in ETABS.
