Analysis with Fespa IS structural analysis and design software
Fespa IS, structural analysis software, offers linear structural and dynamic analysis. All the analysis procedures are performed through a very powerful, fast and accurate solving algorithm. The speed of calculation is phenomenal.
The solution algorithm is equipped with the current trends of mathematics and engineering. For example complete CQC of modal responses, mass matrix formation with distribution of the mass at the nodes, six degrees of freedom per node, care for rigid diaphragms, automatic calculation of the number of mode shapes for 90% mass sum, automatic check for structural irregularities, works due to axial and shear forces-bending and torsional moments.
After the analysis procedure is finished, the engineer can use the three dimensional wire frame view tool (3DV) to:
- Display the deformed geometry of the model based on any load, or combinations of loads.
- View the animated deflections of the model.
- View the animated various mode shapes of the modal analysis.
- Display the shear, moment and axial force diagrams.
Soil – Structure interaction
Fespa IS performs the analysis and design of buildings taking into account the soil-structure interaction. The 3d model is equipped with an especial element which represents the footings supported on elastic subsoil. This is of great importance for the correct distribution of seismic forces within the structure.
