Single Cross Section Trimming
RAM Concept offers six different types of single cross section trimming:
Max Rectangle The top and bottom of the cross section is trimmed, and other pieces may be removed to produce a cross section with a uniform top and bottom elevation, and a maximum area. The "rectangle" formed may actually be multiple separated rectangles with the same top and bottom elevations.
"Beam rectangle" trimming (left) and "Slab Rectangle trimming" (right) showing revised cross-sections. The shear core is now the same as the cross section.
Beam Rectangle Vertical slices of the cross section are removed until the remaining portion is the maximum height rectangle possible. This rectangle can be multiple separated rectangles with the same top and bottom elevations.
Slab Rectangle The top and bottom of the cross section is trimmed to produce a cross section with a uniform top and bottom elevation, and a maximum width. If multiple maximum-width rectangles are possible, the deepest on (maximum area) is used. The "rectangle" formed may actually be multiple separated rectangles with the same top and bottom elevations.
T or L The top and bottom of the cross section is trimmed, and other pieces may be removed to produce a cross section with a uniform top elevation, and only two bottom elevations (flange bottom and web bottom). The Tees and Els formed can be joined (such as double-tees) or separated. Rectangles are considered the same as flangeless Tees.
Inverted T or L Same as T or L, but with the flange on the bottom.
Max Shear Core The top and/or bottom of the cross section is trimmed to produce a cross section with the maximum shear core area.
None - No (single) cross section trimming is performed.
