ACI 318-11 Appendix D Section D.3.3.4.3(D) and Section D3.3.5.3(C) require the design loads from seismic be increased by the amplification factor, Ωo, if the embedded anchor concrete capacity (tension or shear), is less than the anchor steel capacity.
Do Section D.3.3.4.3(D)...
I agree there shall not be ‘break up’ is relative short skewed shear wall. But for a long one or if there are actually several separated (by windows and doors etc.) short shear walls in the skewed wall line, then the use of several ‘supports’ seems more realistic. Selection of the ‘support...
The main point of my first question is where should the ‘support’ location be. To describe the question more clearly, I assign some numeric values for discussion. Say the skewed 45-degree shear wall is 28.28 feet long and one end of this skewed wall meets the right elevation wall of the...
Normally the wind or seismic loads from flexible horizontal diaphragm structure are distributed to the shear walls based on the assumption that the roof or floor acts as simple beams spanning between the paralleled shearwalls in the direction of the loads. The distances between the paralleled...
