WebNov 7, 2024 · ASCE 7. The story drift of a building provides valuable information about its structural behavior under seismic loads. These could cause large horizontal deformations and even instabilities. Some standards, therefore, call for a check of the story drift in its center of gravity. It indicates, for example, if a second-order analysis (P-Δ effect ... WebSince ATC 3-06, drift limits as specified in codes from the U.S. have three objectives: limit inelastic deformations in ductile members, limit lateral displacements that may compromise the structural stability of the building, and limit damage in nonstructural components that could pose a life-threatening hazard (ASCE 2016).
