Loadcap is a software for the bearing capacity and settlements computation on rocks and loose soils, according to the methods of: Terzaghi (1955), Meyerhof (1963), Vesic (1975), Brinch Hansen (1970), Meyerhof and Hanna (1978), Richards et al. (1993) and computation of bearing capacity factors. In the software it is possible to chooce several types of settlements such as: Elastic (Timoshenko e Goodier, 1951); ii) Oedometric; iii) Schmertmann (1970) and Schmertmann et al. (1978), iv) Burland e Burbidge (1985); v) post-seismic (Boulanger e Idris, 2004; Idriss e Boulanger, 2008; Pradel, 1998; Yasuhara e Andersen, 1991)
Moreover, Loadcap solves liquefaction cases using the method of Seed and Idriss (1971) and allows to carry out soil reinforced analysis with geogrids by computing of the increase bearing capacity, deformation in the reinforcements, strain tensile force for membrane effect.
Bearing capacity, settlments – Loadcap: calculated at any point either inside or outside the foundation.
Bearing capacity in seismic conditions: SHIKHIEV & JAKOVLEV, RICHARDS

Note:
Geostru company created a service available on the Geoapp web page where there are several applications for making online calculations. Some of these can be used together with Rock Plane, for example: Bearing capacity; Lithostatic tensions; Liquefaction (Boulanger, 2014); etc., more details are shown in the Geoapp Section of this Help.
