DEFLECTION OF A TRUSS STRUCTURE USING VIRTUAL WORK AND STRAIN ENERGY METHODS
The roof truss shown in the figure below is comprised entirely of equilateral triangles.
a) Calculate the mid-span vertical deflection at joint F using virtual work theory (unit load method). Propose a modification to the force locations and calculate the vertical deflection at joint F using strain energy method & discuss the differences of the results calculated at a and b as above.
The cross-sectional area of the compression members is 3790mm2(using UK channel section of 2009030mm), while that of the tension members is 1300mm2(using UK channel section of 1005010mm). Young's modulus is 210000Nmm2.
