Consider the truss structure in the figure below. All diagonal members have axial stiffness EA, while the chord members have axial stiffness of 2EA. Using unit load method, find the vertical deflection at joint B. Feel free to use a spreadsheet to help with the tedious calculations, but please be sure the calculation steps are well set out. 8m A EA 6m 20KN Df 2EA EA 6 m 2EA B 20 kN EA 6 m E 2EA 15 KN EA -6m EA = 100×106 N C
