I've run Inplace Analysis and from the results I've found error below:
** ERROR - MAXIMUM NUMBER OF ITERATIONS EXCEEDED IN T-Z AXIAL STIFFNESS COMPUTATION FOR PILE 101P FOR AXIAL LOAD ,P = -0.301391E+08,WITH DEFLECTION = -0.856904E+01 MAX. DEFLECTION DIFFERENCE FOR LAST ITERATION = 0.137781E+00
*** POST PROCESSOR TERMINATED DUE TO PREVIOUS ERRORS
This error is gone when I removed SD (Shear deformation) from OPTION card in SACS Input file .
Any other correct solution please advice
The shear deformation option is modifying the stiffness of the structure which in turn is causing different Pilehead loading in you PSI analysis. Section 5 of the PSI manual provides guidance on how to solve this issue. Specifically item 2 suggest inspecting the T-Z curve for discontinuities, and modifying the TABR values or T-Z curves to help with convergence.
