The MAX (Support Walls) programme allows the analysis and calculation of: - Gravity retaining walls - Semi-gravity retaining walls - Cantilever retaining walls - Step retaining walls -Retaining walls with buttresses - Retaining walls with corbels and/or counterweight - Retaining walls made of concrete or stone - Retaining walls on foundation piles - Retaining walls on micropiles - Retaining walls with active and passive tie-rods - Retaining walls with spur or foundation tooth - Retaining walls with head restraint to simulate cellar walls CALCULATION METHODS USEDThe calculation methods implemented in MAX are the following: - Rankine, Coulomb, Culmann and Mononobe-Okabe: calculation of thrust in both static and seismic conditions - Terzaghi, Meyerhof, Hansen,Vesic, Berezantzev: calculation of the bearing capacity of the superficial foundation and deep foundation (foundation piles and micropiles) - Fellenius or Bishop: stability analysis in the vicinity of the work - FEM (Finite Element Method): calculation of the stresses compound walls (tie-rods, piles, buttresses and piles) - Permissible stresses or Limit State Method: Calculation of reinforcement and verification of sections INPUT DATA- Geometry of wall and elements present (buttresses, brackets, piles, tie-rods) - Insertion of overloads (concentrated and/or distributed) - Insertion of loads on the wall - Definition of stratigraphy of foundation soil and embankment - Definition of height of water table upstream and downstream of the wall - Geometry and type of piles - Reinforcement parameters (face reinforcement, foundation reinforcement, foundation pile reinforcement, buttress reinforcement) OUTPUT RESULTSAfter the analysis is completed MAX allows all results to be displayed: - Thrust wedges - Pressure diagrams - Discharges at pile head - Stress diagrams (facing, foundation, piles, etc.‎) - Thrust diagrams - Creep surface with minimum FS - Calculated reinforcement - M-N diagram of sections - Analysis of the wall in static and seismic conditions - Each displayed drawing can be printed - Print of the Calculation Report in Italian and/or English NORMATIVE - NTC 2008 (Technical Standards for Construction) and its integrations - D.‎M.‎ 88 + D.‎M.‎ 96 - NTC2018 - Circular 21 January 2019 n.‎7 C.‎S.‎LL.‎PP
