2D plane frame structures

  1. Below are two 2D plane frame structures (FRAME 1 and 2):
    You are required (before completing any analysis by hand or using GSA) to qualitatively
    draw the deflected shape, bending moment, shear force and axial force diagrams for each
    structure (FRAME 1 and 2).
    You should then change the supports from encastre to pin supports and repeat the same
    qualitative exercise described above.
    Once you have completed the above – create an analysis model of each structure (FRAME 1
    and 2) and analyse them using GSA. Compare your qualitative results with those from GSA
    and describe and explain any differences observed. Do not worry if your qualitative results
    differ (that is expected) – the important thing is to reason why to demonstrate learning.
    Note: you are free to choose the length of elements L1 and L2 (suggest between 5 and
    10m).
    Show how you have checked your GSA models for both frames and report on this.
    For FRAME 1 ONLY determine what value of P3 and P4 will give you a horizontal
    deflections x = 10mm and vertical deflection z = 15mm (see FRAME 1 Fig. b for
    reference). Note that both forces are applied simultaneously
