Arrived early in the morning, segments of roof truss which consists of main truss, fascia truss and tie truss was combined. Beam section of 152x6.0 was assigned to the middle chord of the main truss. On the other hand, beam section of 102x3.0 was assigned to the top chord and bottom chord of tie truss and beam section of 76x5.0 was assigned to the middle of tie truss. Supports that resists vertical translational motion were located at node 114, 58, 2, 155, 99, 43, 167, 111 and 55.
The analysis yielded a maximum deflection of 21.94mm at node 189. Based on the analysis, plane flexural buckling and lateral torsional buckling check is adequate. Checks for axial stress for each member is adequate.
