Load capacity of the mixed bench and slab foundation. Numerical simulations and analytical calculation model

Abstract The paper presents results of a numerical investigation on load capacity the mixed bench and slab shallow foundations (often used in process modernization old, antique buildings, which are suffering from lack capacity). main trouble with use existing analytical approaches is non-unique foundation level slab, they could even be founded different geotechnical layers. Proposed model based Brinch Hansen (EC-7) approach deal such problem. Results 2D 3D modelling (ultimate foundation) compared to obtained by using proposed approach. Influence soil above also investigated. Different width length ratios analyzed (from “short” “long” foundations). Usability engineering practice proved simulations; safe side quite acceptable margin additional safety.
