Sidesway. -- Analyses of the frame indicated that the principal resistance to side sway forces is provided by the side wall stud to rafter joints, corner post to rafter joints, end wall stud and corner post to tie beam joints, and end wall stud and corner post to sill joints.
Use of corner bracing was shown to substantially reduce sidesway deflection of the frame, but the need for bracing in relation to the use of siding or sheathing and the most efficient type of cross bracing for the frame requires additional study.
Another important reference is the allowed deflection of the frame, particularly as it relates to sidesway
and the method used by the manufacturers' engineers to calculate that deflection (i.e., either bare frame calculations or composite effect of the building system).
restraining force factor (mD) indicates the amount of lateral load required to be resisted by the center building frame and how much is being resisted by the SIP diaphragm.
It also has a front stretcher and front rail, which ensures satisfactory sidesway
strength of the front frame.
There are no published acceptance levels for school desks or tables subjected to front to back or sidesway
cyclic load tests.
