The program did not do seismic rigid diaphragm analysis in both force directions, it only analysed east-to-west and south-to-north directions. This became problematic when deflection analysis was added to the program; due to hold-down configuration, stiffness can be different in opposing directions, so that rigid analysis is required in opposing directions.
Note that direction of force was being considered when distributing shear within the line, based on the stiffness of individual segments, as it should be.
In Plan view, the seismic shear force was displayed as a bi-directional force, now it is displayed as a directional force (similar to how wind forces are displayed). When you select to display critical forces, the worst-case seismic force on each shearline is now displayed.
