Beams that are part of the seismic force resisting system (concrete moment frames) often have about the same reinforcing at the top and bottom of the beam because: choose one of the Questions options: 1. earthquake forces can load the building in any horizontal direction 2. the top reinforcement helps to confine the concrete when subjected to earthquake forces 3. the "balanced" reinforcing distributes earthquake forces more evenly 4. the added reinforcing steel gives the beam significant additional strength
