8B. ANALYSIS PART 2

CHAPTER 8B 'ANALYSIS' 123 The program also allows us to see in real time the deformation state of the beam and the edges of the cross-sections where the plastic joints are created, for each step of the analysis. There are two methods of imaging the vector. The first way is by selecting a step from the list (the selection becomes blue) and you will see for this step the state of the carrier and the points of plastic joints. The original, undeformed state of the carrier is shown in grey. The deformed carrier is shown in red and the coloured dot shows the edge of the plastic joint. This dot, depending on the size of the turning angle of the plastic joint, is coloured in three colours. Blue when θ θ cr S R ≤ = θ pl = 0.5 pl = 0.5 pl d d d γ γ Rd Rd Yellow when Red when
