The Washer Settings setup window ( Job Settings )

  • " Double thick hardened " and " Heavy plate " washers are used for A490 bolts that are greater than 1 inch in diameter when they are applied to slots or oversized holes -- only their thicknesses are set up here, the rest is done automatically -- see Table 6.1, AISC Thirteenth Edition , p. 16.2-41.

  • To open Washer Settings
  • " OK " " Cancel " " Reset "
  • When a " Bolt type " is selected for a particular connection, particular types of washers are automatically associated with the grade of bolt and hole type. Also, different washers may be appropriate depending on whether or not the bolt is to be fastened in the shop or in the field.
  • For instance, for one bolt type you may want two washers of the same type and thickness, one washer for the head and the other washer to go under the nut, except when that bolt goes into a slot, in which case you want two different types of washers under the head (the stronger washer to go in the primary position, closest to the steel) and two different types of washers under the nut (again, the stronger washer to go in the primary position).
  • The Washer Settings window lets you define what kinds of washers and how many of those washers you want assigned to what bolt type when that bolt type is used for specific hole types or in the shop or field. You can assign shop bolts different types of washers than you assign to field bolts.
  • The Washer Settings window ensures standardization in the way that washers are applied to specific situations, and thus aides the streamlining of fabrication processes.

Assigning washer types to bolts :

Following is a suggested procedure to use when assigning washer types to bolts. You may, of course, skip any of these steps that do not apply.

1 . Begin by defining the thicknesses of the washers to be used in your current Job . This is done under the heading " Washer thicknesses ." Washer thicknesses are used for 3D modeling and to calculate " Bolt stick-through ." You can enter thicknesses from ' 1/16 ' inch to ' 3-0 ' feet (' 2 ' mm to ' 914 ' mm for ' Metric ')

1a : To " Flat washers " and/or " Hardened washers " and/or " Double-thickness hardened " and/or " Bevel washers " and/or " Plate washers " (round plate, square plate) and/or " Heavy plate washers " and/or " Material plate washers " and/or " Direct tension indicator ," type in the thickness (in the primary dimension " Units " or other units ), then Tab out of the field.

2 : If you plan to apply ' Material plate ' washers to particular washer situations (bolt type, etc.), press the " Material Plate Washers " button to review/adjust the settings on the Material Plate Washers window. You can safely skip this step if you do not use material plate washers.

Material plate washers are made of rectangular plate , unless the length and width of the washer created when bolts are generated for connection designed connections matches the size of a flat bar entry on the Preferrred Flat Bar Sizes list; in that case, they are made of flat bar material. You can create submaterial details of these washers. If you choose to ship such washers loose , they are created as one or more legacy miscellaneous members, of which you can also create member details .

3 . Select the bolt type that you want to assign washers to.

Changes made for a selected bolt type apply to that bolt type only. Each bolt type may be assigned a different set of washers for shop bolting or field bolting through various hole types.

Each bolt type that is listed was originally defined in the Bolt Specifications . This means that if you add a new bolt type to the appropriate tab in the Bolt Specifications , then re-open this window, the new bolt type you just added will be listed on this window.

The " Connection design method " lets you know which tab in the Bolt Specifications defines the bolt types that are listed on this window ( Washer Settings ). Of course, it also tells you which " Connection design method " is selected at Home > Project Settings > Job > Design Settings .

4 . Under the heading " Shop Bolts ," assign washers to bolts for fastening structural members and their submaterials together in the shop (shop bolts). Shop bolts are drawn on member details.

You need to set up washers for each different " Hole Type " (' Standard ', ' Short slot ', ' Long slot ', or ' Oversized ').

hole types

Types of " Washers Under Head " are defined separately from types of " Washers Under Nut " of the bolt. One , two or no washers may be placed under the head and/or under the nut. For one washer, select a type under the " Primary " position only. For two washers, select a type under both " Primary " and " Secondary " position. For no washers , select ' None ' for both the " Primary " and " Secondary " positions.

The " Primary " position is the position closest to the steel being fastened; the " Secondary " position is the position closest to the head/nut.

Types of washers that can be selected include ' None ' (if you don't want a washer in that position) or ' Flat ' (for flat washers) or ' Hardened ' or ' Double thick hardened ' or ' Bevel ' or ' Square plate ' or ' Heavy plate ' or ' Direct tension indicator ' or ' Round plate ' or ' Material plate '. You'll find all but material plate washers listed in the " Remarks " column of the bill of material and in various shop and field bolt reports. Material plate washers, unlike the other washers shown above, are listed as submaterials and not in the " Remarks " column.

' Double thick hardened ' ( DTHD ) and ' Heavy plate ' ( HVPL ) washers are used for A490 bolts that are greater than 1 inch in diameter when they are applied to slots or oversized holes -- this is not set up here, but is done automatically. See Table 6.1, AISC Thirteenth Edition , p. 16.2-41.

If you are usihg ' Material plate ' washers for a particular situation (bolt type, etc.) that is specified here on this window ( Washer Settings ), then the choices made on the " Material Plate Washer " window apply to that situation and to all other situations where material plate washers are applied.

If you are using TC bolts, then check the box for " Use tension control (TC) bolts ." If you are not using TC bolts, then leave the box not checked. A TC bolt is a bolt with a splined end extending beyond the threaded portion of the bolt. The bolt is installed using a special wrench that removes the splined end when the bolt is tightened to the proper tension. The option to " Use tension control (TC) bolts " is checked ( ) by default for "F" type bolts, which means that if you set the non-moment " Bolt type " to an "F" type, connection design will automatically design non-moment connections with TC bolts.

5 . Under the heading " Field Bolts ," assign washers to bolts for fastening structural members together at the construction site (field bolts). Unlike shop bolts, field bolts are not drawn on member details.

The entry fields under " Field Bolts " are the same as those under " Shop Bolts ." See step 4 for instructions..

6 . You have now assigned washers to go on the specific bolt type you selected in step 3 . If you want to assign washers to other bolt types, then repeat these steps for those other bolt types.

When you are done making changes to the Washer Settings window, press the " OK " button (or the Enter key) to save the changes you have made and close the window. Please note that if you have made changes to this window and want to ensure design consistency throughout the Job, you should interactively mark for processing (or Process Selected ) all members in your current Job, then Process and Create Solids .

The " Cancel " button (or the Esc key or the button) lets you close the window without saving any changes made on it.

The " Reset " button undoes all changes made to this window since you first opened it. The window remains open.
