To Add an Arbitrary Shape to the Database As-zz Stress, & As-yy Stress) shown in the figure Shear Stresses for more information on the shear area factors (As-zzĭef, As-yy Def. The center of the cruciform will reflect the centroid of the section with the tips of the cruciform representing the distances from the neutral axis to the extreme fiber. These shapes will generally be rendered using a greenish cruciform shape.The "d" values (the distances to the extreme fibers) allow the program to calculate stresses at the extreme fibers. Thick) value for the cross section is used to determine the pure torsional Everything else will be calculatedįor them (forces, deflections, stresses).

Type is provided so that any shape can be added to the shape database.ĪISC code checks are not calculated for arbitrary shapes since their General Shapes Arbitrary ShapesĪrbitrary Shapes are a special, catch-all shape. The aluminum shapes and databases are more fully described in the Aluminum - Databases section. US, Canadian and custom Aluminum shapes are accessedįrom the Advanced tab of the Ribbon and then clicking the Aluminum tab from within the Shape Database Editor dialog. CSA O86 shapes are actual sizes.Īllowable stress values for each shape are based on the speciesĪnd grade information given in the selected design code. Note that the NDS dimension lumber shapes are all nominal sizes. You may also design for multiple plies of The available wood shapes are based on the dimension lumber and postĪnd timber shapes given in the NDS or CSA O86, depending on what code you have chosen as your Wood design code. See Concreteĭatabase for more information. Of shapes currently supported: Rectangular and Round. Shape code that may be assigned any depth or width. Instead, they are defined using a parametric Steel Databases for more information Concrete ShapesĬoncrete shapes do not have a predefined database like hot rolled andĬold formed steel. The cold formed shapes and database are more fully described in the Cold Manufacturer and custom cold formed shapes are accessed by clickingįrom the Advanced tab of the Ribbon and then clicking the Cold Formed tab from within the Shape Database Editor dialog. Type in Search keywords: Virtual Joist Girders Cold Formed Shapes For additional advice on this topic, please see the RISA Tips & Tricks webpage at /post/support. These shapes are available by selecting Virtual Joist Girder or Virtual Joist from the Database menu. The Steel Joist Institute (SJI) has put together Virtual Joist and Virtual Joist Girder tables which convert common joist and joist girder sizes into equivalent wide flange beams. The hot rolled shapes and databases are more fully described in the Hot Hot Rolled ShapesĪISC, Canadian, Trade Arbed and custom Hot Rolled shapes are accessedįrom the Advanced tab of the Ribbon and then clicking the Hot Rolled tab from within the Shape Database Editor dialog. The Section Sets spreadsheet or on the Primary They may be typed directly into the Shape field on Names for each shape type follow a syntax so that There are different types of shapes for each material type including Shoot the importing of a RISASection shape You may type in the names directly, select shapes from these databases You may also choose from shapes created in RISASection. Shapes such as Hot Rolled Steel Wide Flanges, Cold Formed Shapes, Wood,Ĭoncrete Tees, etc. For each material, there are several databases of common structural
