General Contractor Practice Exam

For a two-story building, the requirement for the minimum embedment depth of an anchor bolt is typically set at 7 inches. This standard helps ensure that the structural connection is strong and can adequately support the loads imposed on the structure, including wind, seismic forces, and the weight of the building materials.

The embedment depth is crucial for achieving proper anchorage of the bolts within the concrete or masonry foundation. Adequate embedment allows for the effective transfer of loads, minimizing the risk of anchor failure which could lead to structural instability. The 7-inch depth is commonly specified in various building codes and construction standards, reflecting a balance between sufficient strength and practical application during construction.

This depth is particularly emphasized for multi-story buildings, where the loads are larger and more complex due to the additional stories. The other choices do not meet the widely accepted requirements for structural safety and stability, which is firmly established at 7 inches for buildings of this height.
