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.

A simply supported steel beam of solid square section is to be designed to absorb shock load as shown. The beam is to be repeatedly bumped at its midpoint by a 20-lb rigid body it supports whose maximum height of drop h is about 1 in. due to vibration. Consider an as forged surface and a fatigue-strength reduction factor of 1.5. Recommend the beam’s minimum cross section required if it were made of C1020, as rolled steel. Design for indefinite life. Take N = 2 (Soderberg).
