Engine »
Enhancement: Enabled generation of pier column interaction diagrams for cases where pier columns are nonlinear and piles are linear.
Engine »
Enhancement: Enhanced printing of XML file content (bearing pad loads, maximum pile displacements).

Engine »
Enhancement: Text output print statements were added so that applied pushover loads are printed per load case.

Engine »
Enhancement: Added corresponding element no. to prints of maximum and minimum strains in piles.
Engine »
Class 3: In dynamic analysis, mass formulation for pile elements was corrected with respect to the Yp-direction mass terms.
Engine »
Class 3: Added control logic to ensure that no equivalent-layer depths calculation would be applied to the layers containing user-defined p-y curves.
Engine »
Class 3: Corrected an error in LFD, i.e., CF loads are now read in properly.
Engine »
Class 3: In dynamic analysis, calculation of nodal damping forces along free-length pile nodes was corrected.
Engine »
Class 3: Storing of pile input values (radius and element length) was updated for the initial soil-stiffness calculations; this update increases convergence rates for cases when resultant forces are approaching limiting values of custom t-z and/or Limestone models.
Engine »
Class 3: Read in of custom q-z values pertaining to multiple soil sets was corrected: previously, user-input of only the first soil set was used in computation of tip resistance.
Engine »
Class 3: Unit conversion corrections were made for input of ground surface elevation in models using SI units.
Engine »
Class 3: Corrected incrementing of the number of free-length pile nodes for nonlinear piles in dynamic analysis.
Engine »
Class 4: Refined the self-weight calculations to handle overlap between: a. Pile cap and pile; b. Pile cap and pier column; and c. Pier cap and pier column members, for cases where pile or pier column half lengths were less than the overlap half-lengths.
Engine »
Class 4: The sign convention for Moment 2 and Moment 3 terms printed to .PLF binary files (for viewing in GUI) was made consistent.
Engine »
Class 4: Corrected units on text output prints of applied span loads.
Engine »
Class 4: For dynamic analysis, corrected sign error for applying prescribed accelerations in Xp and Yp-directions.
Engine »
Class 4: Default directions of line loads applied to masts and mast arms now point in the positive Yp-direction.
Engine »
Class 5: Added conditionals to handle null values in bearing pad element id vector, i.e., when no bearing pads are used. No change in analysis results is confirmed.
Engine »
Class 5: Unit of soil torsion force prints is corrected in the text output file.
Engine »
Class 5: Corrected array length assignments and value-initializations for internal data arrays throughout engine code.
Engine »
Class 5: Opening of the binary file 'STR' was relocated to the engine main routine instead of within a subroutine call. Otherwise, in rare instances, opening of the file within a subroutine was leading to write permission errors on some Windows 7 machines.
Engine »
Class 5: Variable assignments involving conversion from double precision to integer values for soil parameters were made explicit.
Engine »
Class 5: Enhanced assignment of program memory to hold dynamic-analysis soil properties in data arrays.
Engine »
Class 5: As a means of increasing solution calculation efficiency, loops throughout the engine code that were exclusively used for debug purposes were deactivated.
Engine »
Class 5: For pile bent models, column count, bent cap sizing, and beam count call-list variables were added to variable lists in associated subroutine calls.
Engine »
Class 5: Eliminated false-positive prints of strain limit warnings.
Engine »
Class 5: For dynamic analysis, initialized degree-of-freedom specific dynamic load locations as 'inactive'.
Engine »
Class 5: Removed outdated flag for reading of user-defined pile cap shear modulus.
Engine »
Class 5: Cleaned up internal comment documentation formatting throughout engine code.
Interface »
Enhancement: Added prints of max column D/C values to binary files (to facilitate D/C plot viewing in the GUI).
Interface »
Enhancement: Cleaned up formatting of text output file for all print options.
Interface »
Enhancement: In 3D Result window, added ‘Pile Cap Forces’ viewing option, to view shear and moment data for the pile cap. This option is available by right-clicking the mouse in the 3D Results window and selecting the 'Pile Cap Forces' menu item.
Interface »
Enhancement: Expanded spring application to allow springs to be applied to a bridge on a per-load-case basis.
Interface »
Enhancement: Added option to specify a customized range of stress contours.
Interface »
Enhancement: Added option to print pile cap nodal displacements and pile cap material properties for pile cap models, in text output file.
Interface »
Class 3: On Analysis Page, fixed issue with pile behavior getting occasionally saved incorrectly when pile behavior is linear, but section description is changed from “Gross Properties” to “Full Cross Section”; same issue for pier behavior.
Interface »
Class 3: On Pile Cap Page, fixed bug in bridge models where bearing resistance was applied globally to submerged pile caps instead of being applied per pier.
Interface »
Class 4: Fixed issue when closing Soil Table if soil set was deleted while using table.
Interface »
Class 5: In 3D Results window, fixed display issues with a) node numbers not showing in one particular case, and b) nodes drawing too small in one particular case.
Interface »
Class 5: On Cross Section dialogs, fixed issue when “%” sign was used in a custom cross section name.
Interface »
Class 5: On Additional Soil Properties dialog, fixed rounding issue for Undrained shear strength.
Interface »
Class 5: In Pile Edit window, fixed drawing issue with pile positioning and H-pile scaling.

Also, fixed issue with extra empty load case getting created when load case is added to model. This empty load cases did not affect the analysis results.
Interface »
Class 5: In Element Selection window, fixed drawing issue for bridge models where piers weren’t centered properly.
Interface »
Class 5: Fine-tuned restriction of Drilled Shaft IGM being required for only for the tip layer’s axial model when Drilled Shaft IGM is used for the tip model, and not for other non-tip-layer’s axial models.
Interface »
Class 5: On User-Defined Stress/Strain dialog, expanded input for Concrete material type to include Poisson’s ratio, and re-implemented the Yield Strain input.
Interface »
Class 5: On Problem page, restricted the changing of existing models to more intuitive model conversions.
