Was sind die besten Werkzeuge für die Strukturanalyse zur Analyse von Stahlkonstruktionen?

Finite element analysis offers an engineer valuable insight into complex structural behavior, however the engineer should have a strong understanding of the underlying physics while employing these tools. A finite element model is as good as the assumptions inherent to the model, and relying solely on finite elements can lead an optimistic engineer to dubious results. In order to ensure the highest accuracy possible of a finite element model it is the duty of the engineer to understand from a first principles standpoint: 1) The assumptions placed on the model, I.e. static vs. dynamic, elastic vs. plastic, shells vs. solid, etc. 2) Any uncertainties inherent to the model, I.e. geometric, material, loading, boundary conditions, etc.

For finite element analysis that could be checked for output compliance, based on design codes, Bentley STAADPro is a very good software. It offers you ultimate control in your design and analyses as parts of the elements are splitted into analytical bits. This, however, does come with its challenges in that it takes more time to assign design parameters to reflect realistic design conditions to the analytical model. For instance, a bit of the element may show deflection as okay but it's only after design parameters DJ1 (Deflection Joint 1) & DJ 2 are assigned appropriately to tell the software the span within consideration for deflection that a realistic result would be gotten. STAADPro has developed "physical model" to fix this.

The top structural analysis tools for analyzing steel structures include STAAD.Pro, SAP2000, ETABS, Tekla Structural Designer, and Robot Structural Analysis.

Dynamic analysis is as well important for machine foundation design. This helps to understand the response of the foundation under cyclic loading. Dynamic analysis helps to understand possible mode of failure and amplitude of forced vibration of the whole system (machine & foundation combined). Understanding the response of this structure helps mitigate against excessive vibration that could cause discomfort to humans and surrounding buildings also, frequency limits are set to ensure that resonance does not occur (resonance occurs when the operating frequency of the system coincides with its natural frequency). STAADPro, ANSYS, Abaqus are software that I know that could be used to carry out dynamic analysis but I am conversant STAADPro.

STAADPro, Robot and ProtaStructure - Steel Design suite are all that have used in designing connection before. I may not be able to compare them but really found ProtaSteel very easy to use. It has an intelligent connection suite that reads the whole structure and assign the most suitable connections to joints. Over all, it is important that structural engineers understand the nitty gritty of having connection design done manually. This is when it would be possible to read output from software and correct output wherever required.
