If wall footings must be stepped, make the steps in 2-foot increments.<\/li> <li>Walls: Avoid pilasters, tapered wall forms, monolithic lugs, corbels, and shelves. Use as few expansion joints as possible.<\/li> <li>Columns: Don&#8217;t reduce column cross section for upper stories of high-rise buildings. Avoid column capitals and round columns.<\/li> <li>Structural slabs: For flat slabs, maintain a constant elevation for the bottom of the slab. For pan slabs, maintain the same pan size throughout the building.<\/li> <li>Beams: Keep all beams the same size if possible. Run beam bolsters parallel to the main reinforcing bars.<\/li> <li>Reinforcing steel: For bars to be placed by hand, 200 pounds per bar is the maximum weight that can be placed economically.<\/li> <\/ul><\/div> ","protected":false},"excerpt":{"rendered":"<p>Designing and building economical structures requires knowing the difference between design decisions that really improve efficiency and those that only appear to.
