WoodWorks Shearwalls A: Major Features 1. Worst Case Design Previously, when wall parameters were left as unknown, Shearwalls designed separate walls for wind design, seismic design, rigid distribution, flexible distribution, and both force directions – a possibility of 8 designed walls for each physical wall in the structure. In practice, at most 4 walls would be designed, because forces in opposing directions are similar, and often only two or three walls would result. It was left to the designer to compare these walls manually and choose the one that was strong enough for all load cases. If you wanted to see design results for the selected wall, it was necessary to “accept” the design for that case and to run the design again. Now, the program automatically determines the worst case of wind and seismic, and for opposing force directions, and designs one wall that is evaluated for all these load cases. Optionally, you can also have the program determine the worst case of rigid and flexible diaphragms. a) Worst Case Wind vs. Seismic Load Case Previously, the program determined the wall parameters needed to resist the forces from the applied wind loads, and then did so for seismic loads separately. As a result, the program could create separate wall groups for the same physical wall, one for wind design and one for seismic design. The program now compares the walls designed for wind and seismic and selects the wall that has the highest capacity. That wall is then used to redistribute forces both within the line and to the shearlines for the rigid diaphragm procedure. b) Worst Case Rigid Diaphragm vs. Flexible Distribution Method Many designers prefer to consider diaphragms to be semi-rigid, and in the absence of a complex numerical model of the structure, wish to design for the worst case of rigid and flexible diaphragm distribution, to cover the whole envelope of possible diaphragm rigidities. A checkbox has been added to the Design Settings called Worst-case rigid vs. flexible diaphragms (envelope design). If the setting is selected, the compares the walls designed for rigid and flexible diaphragm forces and selects the wall that has the highest capacity. That wall is then used to redistribute forces both within the line and to the shearlines for the rigid diaphragm procedure. c) Worst Case of Opposing Force Directions It is possible for the force in one direction to be slightly different than the force in the opposing direction. For wind design, this can occur for a mono-slope roof or eccentric ridge line. For both wind and seismic design, it can occur when forces are distributed due to deflection and there are asymmetries in the hold-down devices or hold-down forces. An example of this is when openings are do not line up and vertical compression forces from the floor above are added to tension forces from the floor below. In rare circumstances, such difference could cause the program to design a different wall for the east->west direction than the west
