::::::English Description::::::

Modelling Simple 2d or 3d input of floors and frames for rapid model generation. Create any arrangement of grid lines to help you input the structure quickly and simply. Import DXF drawing to automatically create grid lines. Import architects’ plans in DXF. The architectural drawing can be ’traced over’ to generate the Fastrak model. Create and work with beams, columns and slabs, handled as design objects not analytical elements. Import models from 3D+ or other 3d based systems, automatically creating a Fastrak design model. No practical limit to the geometry of the model. Inclined beams, floors, complex roof structures, trusses etc - all are modelled in Fastrak. Floors can be tied by bracing or diaphragm action. Frames can be rigid or braced with X, A, >, /, K etc. Members can be any material including concrete and timber. Model Courtesy of Billingtons Structures Model Courtesy of Billingtons Structures Design Simple, composite with decking, composite with PC planks, continuous and back-span beams. Rolled sections, plated beams, Fabsec, Westok, Porthole, ASB’s and Slimflor beams. Web openings with or without stiffeners. Simple, concrete filled or rigid (moment) columns. Frame stability from bracing and/or rigid frame design and/or concrete shear walls. Model Courtesy of Robinson Construction Composite Beam Design Automatic Loading Facilities Distribution of all loads including lines, concentrated, and partial area, to the supporting structure. Directional wind load distribution. Calculations of notional horizontal forces for the entire structure as per BS 5950-1:2000 for sway and lack of fit. Reduction of imposed loads per BS 6399. Automatic Building Design Detailed assessment of Lambda cr for the entire structure by inspection of every floor-to-floor drift of every column under the relevant notional horizontal load case. Comprehensive implementation of the assessment of floor vibration to SCI P076. Results Detailed design output or design summaries for submission to checking authorities, in Microsoft Word™ format if required. Beam end reactions and base reactions in Microsoft Excel™ format or on drawings. Detailed design drawings of plans and elevations, including beam end reactions, floor slab reinforcement requirements, span direction, etc - automatically layered on AutoCAD™ drawings. Full take off lists including steel and concrete material and floor areas, in Microsoft Excel™ if required. Creation of 3d model for integration into 3D+™, S-Frame™, Orion and a wide range of other modelling systems.
