WebAPA's FTAO calculator is an Excel-based tool for professional designers that uses FTAO methodology to calculate maximum hold-down force for uplift resistance, the required horizontal strap force for the tension straps above and below openings, the maximum shear force to determine sheathing attachment, and the maximum deflection of the wall system. WebTo justify a wood diaphragm as rigid, the deflection of the diaphragm can be calculated using SDPWS 4.2.2, the deflections of the supporting shear walls can be calculated using SDWPS 4.3.2, and the numbers can be compared using the above checks. chuck e cheese worcester ma hours https://hashtagsydneyboy.com
