The beams on a terrace are to be designed uniformly at the critical section. After running an analysis, the critical section carries a deadload of 100 kN-m (rounded off to include weight of the beam) and a liveload of 140 KN-m. The beam conditions must be decided. (Consider Flexure ONLY) 1. Design a W14 I-Section whose unbraced length is 9 meters and Cb = 1.0. In designing, limit your Mu/Mcap between 80% to 90% to consider economical value. 2. What if the beam is to braced at the first third point only, Cb=1.0? Determine the ultimate moment capacity of this particular beam. 3. What if the beam is continuously braced wherein Lb=0? Determine the ultimate moment capacity of this particular beam.
