This document summarizes new features and enhancements in the STRUDS structural analysis and design software, including improved 3D visualization, direct import of CAD plans, automatic mesh generation, stress contour visualization, modeling of industrial structures, improved seismic and slab design, minor bug fixes, and more.

2. Salient Enhancements
• Enhanced Graphical User Interface with better visualization in 3D
• Directly Read Architectural CAD Plans to create Structural Model
• Grid inputs made easy by reading directly from Excel sheet
• 6 Noded Triangular iso‐parametric Shell Finite Elements introduced in STRUDS
• Free Mesh Generation to discretize model automatically including consideration of
Level difference in Floor slabs (Like Sunk Slab)
•Stress Contours to visualize the behavior of Structure – Including Principal and Von
Mises stresses
•Modeling of Industrial buildings with RC Frames and Steel Trusses in 3D
… Contd.

3. Salient Enhancements
•Detail drawings enhanced and improved based on SP:16 and IS:13920
provisions
•Improved and enhanced Seismic load computations by Response spectrum
(In case Floor considered as Rigid Diaphragm and In case of eccentricity in Center of
Mass/Rigidity)
•Design & Detailing of Narrow width Beams improved
•Irregular Shaped Slab design improved (Redesigning and editing)
• Effect of Footing boundary conditions when Wide columns effect (Center of
Column not matching Structural Node) taken into consideration is implemented
•Column ties design logic of T , L and Circular column improved

4. Import of Architectural CAD drawings ‐ first of its kind feature
Using this new feature, CAD drawing of Building Plan can be directly imported in
STRUDS for generation of structural plan. Save substantial time in modeling the
structure. Higher accuracy in input.

5. Architectural import with all entities
All layers from original CAD drawings are available for display and can be made
on/ off as required – The Structural Designer has Architectural Plan view in
the background

6. Tracing of imported Architectural Drawing
User can draw structural model by tracing entities from imported CAD Architectural
Drawing

7. New easier option for generation of grid lines
New option added for grid line generation to import excel file data

8. Generation of grid lines by importing excel file data
Grid lines can now be generated by importing data from excel file. Substantially
enhances the speed of creation of model using Grid approach.

9. Use grid lines to trace structural plan
Structural plan can be quickly created using the grid points

10. Finite Element Analysis of Slabs as shell element (Beta release)
Discretization of Surfaces using Intelligent Free Mesh
Algorithm – 6 Noded Triangular Finite Elements
Considered

11. View Finite Element Analysis results in postprocessor
Contour Diagrams (Filled & Vector) are produced for All Stresses and Displacements
With Value table. Colors are graded from Maximum to Minimum

12. Quick Modeling of Industrial Structures
Shrinking effect at
joints for better
visualization
User defined steel Plane Trusses can be modeled and placed them on concrete frames

13. Minor Improvements / Fixation of Bugs
Preprocessor
• Enhanced accuracy in report for contribution of columns in EQ resistance
Design
• Matching of reports for analysis and design loads for shear walls subjected to
earthquake and wind loads.
• Effect of boundary conditions as hinged / fixed at footing level while considering the
option ‘Consider stiffness at the center of column’, in the ‘column offset’ command.
• Deflection control check for Steel Grade Fe550 improved in design of slabs.

14. Minor Improvements / Fixation of Bugs
Detailing
• Proper directions of arrows indicating section lines for generation of beam cross
section drawings.
• Display of dimensions in millimeters in DXF drawings for slabs, beams, columns and
footings for better graphics judgment.
• Hooks at both ends for top bars and bottom curtailed bars in L/s of beams have been
added as per generally accepted detailing practice.
• Enhanced and more accurate curtailment for bottom steel in beams.
• New provision to provide curtailment positions from support (values for ‘C’ and ‘D’)
under 'Beam Detailing Parameter' dialogue box in beam design.
• Generation of Beam L/s DXF drawings considering effect of orientation of columns.
• User defined control parameters for curtailment of top extra bars as per SP‐16
• Text annotation of Beam numbers improved in print option of Beam Plan layout
