Elevation View

In Elevation view, you are able to see the forces acting on shear walls and shear wall segments, the material specification of the walls, the dimensions of wall segments. It is the only place in the program that all this information appears in one place.

These data correspond to the Design Case being viewed (combination of wind or seismic, rigid or flexible diaphragms, and force direction). This can be changed via the Show menu.

All of the information described below can be toggled on and off using the Show menu or the Options settings to reduce clutter and focus on what you want to see. You can choose to show a single wall or all the walls on the line, or all levels on the structure or a subset of the levels.

Design Forces

Elevation view shows all the design forces on each shear wall as arrows in the drawing. These include

• total shear line force
• total force on each wall and each wall segment
• unit shear line diaphragm force
• unit design force in each wall segment and FTAO pier
• dead and wind uplift line loads
• drag strut forces
• hold-down forces and components due to overturning, dead, or wind uplift
• force-transfer strap/blocking forces

The following forces are also shown

• Out-of-plane component and cladding wind loads
• out-of-plane wall and anchorage forces for seismic design

Forces for Drag Strut And In-Plane Anchorage Design

For seismic design, an option in the Show/Hide menu allows you to show the shear line forces for drag struts and in-plane anchorage instead of the forces used for shearwall design. These forces are based on the diaphragm design force, and other factors described in seismic design requirements for drag struts and anchorage are applied.

For perforated walls, the force shown fordrag struts is also based on v_max rather than the shearline design force v as described in Drag Strut Forces in Perforated Walls and Lateral Anchorage Shear Force. In addition, the Uplift Anchorage Force t is shown.

Material Specification and Design Results

When shear lines from just one level are selected, underneath the wall line it shows, for the wall with the critical segment for design:

• the designed material specification
• the design group
• the interior and exterior sheathing capacity
• the design shear force and total capacity of the critical segment
• the C&C nailing and out-of-plane bending forces and capacities.

This information appears only if you are viewing a single level of the structure.

Due to space limitations, these data cannot be displayed for all the walls on the line, so you have to select a single wall to view this information for walls that do not contain the critical shear wall segment. Alternatively refer to the Design Results output to get this information for walls that do not contain the critical shear wall segment.

Other Information

Elevation View also showa

• dimensions all wall segments, openings, and FTAO piers
• shows segment and pier aspect ratios and factors
• displays non-shear-resisting segments in gray, that is, non-shear walls, segments with high aspect ratios, and areas above and below openings (except in FTAO walls).
• indicates with large bold lettering which walls on the line have failed.
• shows the profile of the roof shape where it intersects the shear line being shown.
