Abstract

Abstract.  Purpose.  Analysis and systematization of the existing software for the calculation of  the foundations and the choice of  optimal software for solving the contact problem in the interaction of foundation with the nonlinear deformable base.  Analysis.  Was performed  overview  of  the  main  software  that are used in the calculation of foundations and bases, analyzed their possible areas of  use.  Were  presented  fundamental  differences  in  the  results  of  determination  the  vertical  shrinkage  of  the  strip  foundation  by  the  analytical method and finite element method in the conditions of planar and spatial  tasks on the basis of PLAXIS.  Findings.  The  software  provides  a  large  library  of  finite  elements  and  it  is  a  potent  analysis  tool.  Using  different  software  would  improve   the  process of calculating the foundations and bases. Integrated system of structural  analysis and design of structures based on the finite  element method allows determining the stress-strain state of structures from static and dynamic influences and performing a number  of structural elements of the design features.  To solve the contact problem in the interaction foundation with nonlinear deformable  base the most advanced option of using is PLAXIS program.  Comparison Results foundation subsidence calculations performed by  the deformed flat circuit by the analytical method and finite elemen t method (PLAXIS 2D), showed that their values differ by only  9-15%.  Foundation subsidence values that were calculated by the finite element method in conditions of spatial problem (PLAXIS  3D)  by  an  average  of  41%  less  subsidence  values  received  in  terms  of  plane  problem  (PLAXIS  2D).  The  relative  difference  subsidence received by the finite element method in terms of spatial problem has a much smaller value (0.00077) than with the   flat problem  (0.0022).  Originality.  In  the  article  was  analyzed  information  about  the  most  advanced  software  for  the  calculation  of  foundations  and  bases,  are  characterized  their  ability,  scope  of  use,  allowing  to  choose  the  optimal  version  of  the  software  for  a specific purpose in solving the structural problem. Practical value. Using software system PLAXIS 3D during modeling of foundation  interaction with the base which deforms unevenly allows you to get more accurate results acting forces and contact stresses.
