To add the Rebar System custom component :
|
|
|
A Rebar System custom component can be added to concrete slabs , concrete walls , elevation walls , CMU walls and pad footings . The rebar system becomes a component of the member to which it was added.
To add the custom component : 1 ) In Modeling , select an appropriate concrete member. 2 ) Choose Model > Component > Add . 3 ) On the custom component selection list, choose " Rebar System " as the custom component you want to add. 4 ) If you are adding the rebar system to a slab, locate a reference point for the rebar system. 5 ) If prompted, locate a direction point. The angle of the line between your reference point and the point you select will determine the direction of the rebar grid. 6 ) The Rebar System Edit window opens. Enter the settings that you want, then press " OK " to close the window. 7 ) If User and Site Options > Modeling > " Automatically process after modeling operation " is set to ' Process and create solids ', the bars will be generated immediately. If not, the bars will be generated in the member the next time the member undergoes Process and Create Solids .
Tip: If you use in-tool selection -- that is, select the member after selecting " Rebar System " as the custom component you want to add -- only concrete and CMU walls, elevations walls, concrete slabs, and pad footings will be selectable. To delete a Rebar System custom component: 1 ) Use the Component Selection Tool and select the component in the slab, footing, or wall. Or , select the component in the Model Tree . 2 ) Press the Delete key (or choose Edit > Delete ). 3 ) Process and Create Solids iff User and Site Options > Modeling > " Automatically process after modeling operation " is not set to a choice that makes create solids take place automatically.
In the Model Tree , the Rebar System custom component is listed as Rebar System @ ( [ x, y, z ] ) when " View By " is set to ' Member piecemark ' or ' Member number '. The Rebar System component is listed under its member, after that member's connection components ( Left End and Right End ), and before that member's submaterials.
To edit a Rebar System custom component or review its settings, you can find the member it is added to and open its edit window. The component's settings will be contained in that window in a section named [ Rebar System ] . To edit a Rebar System custom component without opening a member edit window, use the Model Tree . You also can use the Selection Filter toolbar item to select the ' Custom Components ' filter and double-click any bar in the rebar system to edit the system. The Component Selection Tool can also be used to edit (and find) custom components.

A Rebar System component is automatically set to "
Graphical " whenever you make graphical changes to any of its bars. For example, when you Edit Material or apply the Extend Rebar Ends tool on one of the bars. This stops the component from being changed during Process and Create Solids . Click here for more information.
Instead of allowing the component to be made "
Schedule group: Any non-negative integer with less than ten digits. Your choice of schedule group is not limited by any configuration option. The group applies to this member only -- see special case below.
Reason to assign a schedule group: The output of the Rebar List Report , Rebar in Member Report , and Bend Schedule custom reports can be limited to particular schedule groups. As a result, you can assign rebar shape material to different schedules, and create separate reports for rebar from each schedule.
A special case: You change the schedule group on one of the rebar shapes. If you press " Yes " when prompted " Do you want regenerate... ," the changed schedule group is applied to ALL rebar matching the options checked in the Change All Options window.
User configuration: You can open the Report Manager window or the Table Edit window to copy, create, or edit rebar custom reports. " Edit " the report to add a comma-delimited list of schedule groups that the custom report will select.

Settings for concrete walls or elevation wall layouts :
Outside mat: or .
Yo u can check one or more of these options. Depending on how many options you choose, a set of up to three rebar mats will be designed. These options the location of the rebar, relative to orientation of the wall that you chose when you placed the component. The names of these options accurately describe the location of the mats when the wall's layout points were placed clockwise.
If Inside is checked (
If Center is checked (
If Outside is checked (
Note: You can uncheck (
Cover: The distance (in the primary dimension " Units " or other units ) from the ends of the rebar to the edges of the wall.
------ Mat settings ------
If ' Each way ' is checked (
If ' Each way ' is not checked (
If ' Corner rebar ' is checked (
If ' Corner rebar ' is not checked (
Corner leg type: ' Custom ' or ' Overlap ' .
If the leg type is ' Custom ' , corner rebar overlaps the adjacent mats on each side by the distance you enter for the " Corner leg distance ."
If the leg type is ' Overlap ' , the distance by which the rebar extends from the corner is determined by the " Horz. in concrete " distance entered in the Reinforcing Bar Definitions window.
Corner leg distance: The distance (in the primary dimension " Units " or other units ) by which the corner rebar extends from the corner, when the " Corner leg type " is ' Custom '.

Settings for CMU walls :
Max spacing: The distance (in the primary dimension " Units " or other units ) between vertical rebar. This is a maximum ; so the distance between one bar and its nearest bar may be significantly less.
Max dowel length: The length (in the primary dimension " Units " or other units ) of any single bar segment. Splices between segments are designed when each run has multiple dowels.
Tie length above footing: The distance (in the primary dimension " Units " or other units ) above the bottom of the CMU wall.
Tie length below footing: The distance (in the primary dimension " Units " or other units ) below the bottom of the CMU wall. The tie's extension below the footing depends on the setting made to this option, and not on the footing (if any) that is modeled below the wall.
