Using the information from the image, determine the member sizes for the top and bottom chord members of the 8.8 m span parallel chord truss shown in above, which is carrying a medium-term UDL of 6 KN/m applied to the top chord by joisting at 0.6m centres. Use C24 timber in service classes 1 and 2. Neglect dead weight of truss. The top and bottom chords are spaced 1.8 m vertically apart on centrelines and are twin members. The diagonals are twin members, and the verticals are single members. The spacing of each bay is 2.2m (top chord member) K12 = (top chord member) λww = What is the moment at the node points (KNm)? Using the method of trial and error, (top chord member) λxx = What is the Bottom cord maximum tensile force (KN)? (top chord member) σm,a,// (N/mm2) What is the load per panel (KN)? What is the permissible bending stress (N/mm2)? What is the axial force in the top chord (KN)? (top chord member) The axial compressive stress σc,a,|| (N/mm2) is given as: What is the moment between node points (KNm)? Euler critical stress is calculated to be (N/mm2): Providing that a single connector and bolt (Nb = 1 and Nc = 1) are to be used in the outer planes of the bottom chord. Determine the medium-term capacity of a 44 x 122 twin member of C24 strength class based on the net area. What is the permissible compressive stress (N/mm2)?
