One of the reason that keeps me going all the time is where every tasks that has been assigned to me gets challenging than before. At the starting of the 2nd week, Monday, 12th of April 2010, I was assigned to analyse a comprehensive roof truss which consists of fascia truss, main truss, tie truss, and cantilever. Will explain more on each of it after this. First, I did a research on the example provided by the program Prokon. It was a semi circular tube, completely different from what I'm going to analyse but it lies the same concept that will somehow makes life easier when it comes to assigning nodes and beam sections. After that, I started assigning the nodes, beam sections, supports, beam loads, point loads and combinations to the main truss, then I proceed with the same process for fascia truss, cantilever truss and finally the cantilever tuss cantilever truss. Now comes my nightmare of combining all 4 segments of trusses and multiply each of them to form a complete roof truss for analysis. Analysis consists of deflection of the trusses which accounts 14.90mm, every member of the trusses pass the check for plane flexural buckling and lateral torsional buckling. Finished on Thursday, 15th April 2010. Below is a few pictures of the finished product.
After conducting the analysis, it yields a deflection of 14.90mm
