RETAINING WALLS

Retaining walls of gravity or cantilever type (reinforced). Geotechnical design using Eurocode 7, EN 1997-1:2004, Geotechnical design – General rules or allowable soil stress. Active and passive earth pressure using Coulomb's theory. Design of gravity walls using Eurocode 6 (EC6) or allowable stresses.
Earthquake analysis according to Eurocode 8 (EC8),  Mononobe-Okabe.
Two different types of cantilever walls exist in the program:

Type-A. Walls with very small back heel. The active earth pressure is computed using Coulomb's theory at the back face of the wall.
Type B. Walls with back heel. The active earth pressure is computed using Rankine's theory at a vertical surface at the end of the heel.
The design of cantilever type walls is based on Ultimate Limit State Design of concrete according to Eurocode 2. The design checks are performed at each tenth of the stem height. The reinforcement of the stem is optimised, and depending on the stem height the reinforcement is reduced toward the top of the wall. The reinforcing bars are automatically placed in the reinforcing bar schedules. Optional Base key against sliding.
Load combinations according to Eurocode 2, Eurocode 7,(EQU, STR, GEO load cases) and Eurocode 0.

DEEP BEAMS

Deep beams with dimensions Leff/h<=2, where Leff is the length and h is the height.

Design according to Eurocode 2, §5.6.4,§6.5, using simple strut and tie model. You can design deep beams subjected to uniformly distributed load (with dead and live components) at the top and bottom faces of the beam.

Load combinations according to Eurocode 2, and Eurocode 0.
