The fourth dimension in building analysis
Intelligent 3d Frame structure
The anakysis of the spatial frame structure takes place according to the FE method. ideCAD Structural generates automatically the FE model using three-dimensional components such as slabs, beams or columns. Construction components can be positioned per mouse-click. When the building model is transferred from ideCAD Architectural, the construction components are already defined. After the data model has been transferred to the ideCAD structural , reinforced-concrete design of columns, beams and slabs can be carried out, cross-section proposals optimized, and reliable and economical cross-sections specified.

Automatic load transmission
In ideCAD Structural, vertical and horizontal loads and line, point and area loads are analyzed automatically using the geometry of the building model. The slab loads calculated with the help of the FE method are transmitted to the beams automatically. Wall loads which have an effect on beams are determined taking door and window openings into consideration. The self loads of the beams are determined on the basis of their geometry. Loads can also be defined independent of the geometry. Slab openings and concentrated loads are included in the analysis of slabs. Wind forces and subgrade reactions are taken into consideration in the superimposition of load cases. Analysis and design results can be determined and printed out for all load case combinations.

The static and dynamic analysis of 3D frame structures
The 3D frame structure consisting of components such as columns, beams and panels is analysed statically and also dynamically, if required. Round, curved or polygonal beams are easy to create in the floor plan. Cross-sections of reinforced-concrete columns can be defined in rectangular, round or polygonal form. Furthermore, oscillations can be animated.

Design of slabs
The static analysis of slabs is carried out with the help of the Finite Elements Method (FEM). The support conditions or boundary conditions are identified automatically using beams. analyses results are measured according to DIN 1045, DIN 1045-1 or EC2 for the assessment of reinforced concrete cross-sections. Static calculations of throughed suspended floors, ribbed floors and coffered ceilings, point-formed supported slabs and joist-free ceilings are carried out with the help of the FE method. Slabs are calculated for elastic bedding.

Design of foundations
Loads from columns are transferred automatically to the foundations. Single foundations are designed for double-axis bending with axial force for all load case combinations. Strip foundations are modeled as beams with elastic bedding. Subgrade reactions, bending moments and loads from the columns are determined automatically. The results returned from the analyses are taken into consideration during the design of reinforced-concrete cross-sections.
