Physical modelling of mat foundations.

CONNECT Edition V9 Updates 7.2 and 7.3

• Combined footing:

  • Improvements in the methods used in finding an optimal footing size that satisfies bearing pressure checks and loss of contact limits.
  • Better estimation of the maximum bending moments and shear forces in out-of-contact situations
  • More economical footing sizes resulting from the above.
  • Messages in the output pane that give a detailed insight into the checks performed by the program at the various stages for each load case

• Machine foundations:

  • A more rigorous implementation of the equations of ACI 351.3R-04 for soil damping constants and soil stiffness coefficients per the Richart and Whitman method and the Veletsos method
  • Improvements in the calculation report to reflect the appropriate code equations for the computation of the above and the performance criteria of the machine

• PLANT mode - Tank foundations and Vertical Vessel foundations:

  • Correction of errors involving loads on the ringwall/foundation due to wind and seismic forces
  • More detailed reporting of calculation results to allow for easier validation of the processes followed by the program.
  • Stricter enforcement of PIP STC01015 rules to ensure that load combinations that were not intended cannot be applied in the model
