Gewöhnlich zeigt traditionelle baustatische Software die Verformungen von Balken mit ihren Querschnitten auf der verformten Schwerachse. ConSteel 15 dagegen benutzt eine fortschrittliche Methode für Deformationsdarstellungen, die feiner und realistischer ist. Natürlich sind die numerischen Ergebnisse identisch, aber mit der verfeinerten Visualisierung kann das 3D-Verhalten der Balkenstruktur besser erkannt werden.

Comparison of chosen methods for estimation of critical lateral torsional buckling bending moment of web-tapered I-beams. In this article, the elastic critical bending moments of the web-tapered I-beams calculated by the analytical and numerical solutions developed last years by researchers involved in the topic were compared with own calculations carried out with available common tools. The main goal was to verify the accuracy and convergence of the results provided by different modern methods and different finite bar elements 1D with 7 degrees od freedom at the node (7DOF).

Introduction

As you may already know, you can check the max, min and min-max envelope diagrams for (first and second order) analysis results in Consteel. But you can also create your own envelope figures…

Introduction

In case of a model with a lot of load cases (wind in different directions, with and without internal pressure, snow,seismic etc.), hundreds of load combinations can be generated acc. to EC but many of these combinations are irrelevant. Running an Analysis on all of the load combinations can take a lot of time, that could be saved, if the relevant load combinations are calculated only.
