![]() Specialized bridge design software will also help with the design portion by performing design and limit state checks based on the response of the analytical model. STAAD is just an analysis engine, some software (LEAP) will use STAAD as the engine, and LEAP just creates the model to send to STAAD to run and then aggregates the results.ĬSIbridge does something similar but uses SAP2000 as the engine. Otherwise, as in STAAD, you need to set it up manually and possibly distribute it depending on the analysis method. Specialized bridge software will have moving live load application tools that make it easy to apply. Substructures have different analysis options too, mainly frame or FEM.Īny analysis software will work, but you need to make sure it applies the live load and distributes it properly. each one offers a better distribution of forces (ie, more conservative to more refined) through the superstructure. There are 3 accepted analysis methods for bridges- line girder, grillage and FEM. ![]() Curved and skewed structures get a bit more complicated. Simple structures are pretty easy to design. ![]() The Obligation of the Engineerĭepends on how simple the bridge is. Shall be given without reservation for the public good.Īnd in fidelity to my profession, I shall give the utmost. Practical use the principles of science and Has been spurred by the engineering genius.
