Analysis of Shear Walls/Panels:

HYST has been implemented in a general static or dynamic analysis of shearwalls/diaphragms and Panelized construction. For shearwalls, two levels of complexities have been considered: one limited to racking deformation as in an earthquake or windstorm, and another in which the wall may be subjected to simultaneous loading in racking and transverse loads, with the addition of vertical (axial) loads. The corresponding computer programs are called WALL and PANEL. The latter can consider general panelized construction with or without rigid insulation in the wall cavity.

The figures above (click to enlarge) show runs of PANEL for push-over tests on two types of shear walls. In the first, the entire wall is covered with a Jumbo OSB panel. In the second, the wall has standard size OSB panels with corresponding gaps.

The figures above (click to enlarge) show runs of PANEL to compute hysteretic behavior of the same shear walls.

PANEL can also be used to predict the time history for the displacement at the top of the shear wall (drift) when the base is excited by an earthquake. The above figure (click to enlarge) shows the calculated response of a shear wall when using the ground motion of the Landers, Joshua Tree Station, California earthquake of 1992. The maximum drift during the earthquake can be extracted from the data to construct a response surface for later reliability analysis or performance base design.
