The sturdiness and strength of a metal building is only as solid as the foundation it rests on. The foundation provides stability and prevents extreme building movement to protect the building and its contents from damage or failure. For this stability, structural steel columns are supported by high-strength anchor bolts embedded in the foundation's concrete.
“Anchor bolts serve two functions,” says Alexander Newman, PE, a forensic structural engineer in the Boston area and author of a book titled, “Metal Building Systems,” now in its third edition. “They help stabilize the steel framing during erection, and they may help transfer horizontal and vertical loads from the framing to the foundation.”
Most people commonly think that the foundation or footer support a building. “They do to a certain extent, but the primary reason for large footer and pier pads is that they act as counterweights to weigh down the building and keep it on the ground,” says Robert J. Quarture Jr., outside sales manager, Mohawk Construction and Supply Co. Inc., McMurray, Pa. “Metal buildings act as large kites in high winds and the footer/ foundation is the primary reason they stay in/on the ground. The piers and anchor bolts also act to tie the entire building design together. The piers and anchor bolts work with the steel design, the panels and the roof to complete one cohesive design and system.”
