Geotechnical engineering analysis is based on modelling the subsoil material and the interacting structure. The modelling parameters which characterise the behaviour of subsoil are obtained from geotechnical investigations.

Geotechnical Engineering Modelling Software Suite (GEMS Suite) deals with finite element analysis of beam foundation, raft foundation, pile foundation & retaining structures.

Beam foundation is adopted in the case of combined footing supporting two or more columns. The combined footing is modelled structurally as a beam foundation resting on the soil. The sub soil may be modelled in several ways. Two common models for the subsoil are:

(a) Discrete spring bed model using modulus of subgrade reaction (also known as “beams on elastic foundation” or “Winkler beam theory”). The soil parameter used for this analysis is the modulus of subgrade reaction.

(b) Elastic half–space model where the subsoil model is replaced by elastic, homogeneous, isotropic semi-infinite continuum. The soil parameters used are elastic modulus and Poisson ratio.

The “Beam Foundations” software consists of two modules incorporating the above two commonly used models of analysis.





One Click Computation

One click computation and analysis for all load cases and models.





Analysis Models

Analysis of the beam foundation using both/either models.





Load Cases

Multiple load cases could be considered.

Beam Diagram

Graphical representation of the Plan and Elevation View of the beam foundation.

Loading Diagrams

Graphical representation of loading diagrams for each load case.

Unit System

Data can be input in either SI units or ‘Commonly used American units’ (Kips for force and foot for length).

Export

Export results to Microsoft Word & Excel

Loads & Moments

The loading may consist of several concentrated loads & moments.

Uniform Loads

Multiple uniformly distributed loads can be specified.

Beam Weight

Self-weight of the beam may be included if required.

Beam Dimensions

Different depths and breadths could be given for the beam. RCC inverted T beam sections and RSJ s could be considered by prescribing EI values directly.

Prescribed Displacements & Rotations

Vertical displacements and rotations could be prescribed if required.
