Fastrak Building Designer Explained
Automated Building and Element Design
Once the complete physical design model has been created and the necessary loading applied, Fastrak Building Designer will automatically carry out the detailed analysis for both gravity and lateral load combinations and will automatically optimize the design for all steel and composite members.
- Lateral analysis of structures using Direct Analysis Method (2005 AISC Specification) - including both P-Δ and P-δ.
- As part of the Direct Analysis Method, Fastrak Building Designer utilizes a rigorous second-order elastic analysis approach, so member forces are obtained more accurately for buildings with a wide range of geometry. In this method, B1/B2 factors are not required.
- As per the 2005 AISC Specification for Direct Analysis Method, K-factors can be taken as 1.0.
- Automatically reduced flexural and axial stiffness (EI* and EA*) as per the 2005 AISC Specification.
- Detailed assessment of drift for the entire structure. Including summary of Δ2 / Δ1 building stability coefficients and seismic story drift (ASCE/SEI 7-05).
- Seismic design of steel members as per 2005 AISC seismic provisions and includes specific requirements for OCBF, SCBF, SMF, IMF, OMF frame types.
- Biaxial bending, shear and axial load included for beams and columns.
- Columns can be spliced as required and forces reported.
- Transfer beams, trusses and hangers can be included.
- Bent beams and bent columns included.
- Building / Frame stability can be provided by various forms of bracing, moment frames, concrete shear walls, or a mixture of all three.
