WebRigid diaphragms are addressed in IBC Section 1604.4, ASCE 7-10 Section 12.3.1.2, and SDPWS Section 4.2.5. In accordance with IBC Section 1604.4, a diaphragm is rigid for the purpose of distribution of story shear and torsional moment when the lateral deformation of the diaphragm is less than or equal to two times the average story drift. Webfrom a rigid or semi-rigid structural analysis (§12.3.1.1), while the 2009 IBC exempts nearly all diaphragms of light-frame construction from a rigid or semi-rigid structural analysis (IBC §1613.6.1).
