Wind Story Drift

Wind story drift is calculated according to ASCE 7 Commentary Appendix CC Serviceability Considerations, CC.2.2 Drift of Walls and Frames. Serviceability loads and load combination are used to determine the shear line forces for story drift deflection. A different apparent stiffness Ga than is published in the SDPWS for seismic design is used to calculate the 3-term deflection equation.
