    Description

    Plugin allows you to process both individually selected slabs, and all slabs in the view or in the document. The main reinforcement of the slab can be performed as separate rebars, or area reinforcement. The analysis of holes is made from the geometry of the slab itself and does not depend on the used families. Plugin can work even on an empty template

    Using

    The main window of the plugin is divided into three zones: selection and analysis, reinforcement settings for slabs and final settings and starting the reinforcement process.

    1

    There are options in the window title:

    arrow collapse (gray) - collapse window contents

    format columns (gray)– opens the window for setting preferred shapes of rebars:

    2

    The drop-down lists in this window are filled with shapes from the current open document.

    cog (gray)– general plugin settings:

    5

    In the group Reinforcement by default you can specify the reinforcement settings that will be set for slabs by default.

    In the group Bending rules the source of rules for rebar bending is selected: SP 63.13330.2018 or EN 1992-1-1. Below is the description of rules from the selected norms. 

    If the option Fix bend diameters for existing types is enabled and appropriate types of rebars are found during operation, their bend diameters will be checked and corrected according to the selected standards. When creating new types of rebars, in the case no suitable ones are found, the diameters are always checked and set.

    In the group Holes check there is an option that allows unchecked in the list a hole, whose circumscribed rectangle has one or all sides less than the specified value.

    Selection and analysis

    17

    Work with the plugin starts with selecting the slabs to be reinforced. To do this, click the button Select and then choose one of the options in the drop-down window: Pick slabs, Select all slabs in current view or Select all slabs in document.

    Only slabs with the enabled property Structural get into the filtering of the selection. The number of selected slabs is displayed at the top of the plugin window.

    The button Select again allows you to reselect the slabs that were processed in the current view when using the plugin.

    Next you need to start the analysis of geometric and parametric data of selected slabs, including hole analysis, using the button Analyze. The number of successfully analyzed slabs is displayed in the upper part of the plugin window.

    Slab Reinforcement Settings

    The direction of reinforcement in the slabs is set based on the given direction of span direction in the slab sketch. The direction of the segment indicating the span direction corresponds to the direction of the longitudinal reinforcement in the slab reinforcement

    On the left side of the zone are two tables. The top is filled with slabs that have been successfully analyzed. For each slab, a checkmark is checked by default in the list, meaning that for this slab, reinforcement is required. The bottom list is filled with holes for the selected slab. For each hole for which it is possible to create a border, a checkmark is set by default to indicate that the hole needs to be framed. If the framing of a hole of a certain shape is not provided by the plugin, the checkmark will be unavailable, and the corresponding icon with a pop-up message will be displayed for the hole. A warning icon is also displayed for holes smaller than 300 mm that are not recommended for framing. To the right of the hole list there are buttons to check all openings available for processing in the list checkbox multiple marked circle outline and to uncheck all openings in the list checkbox multiple blank circle outline.

    On the right side of the zone are tabs for specifying settings for a particular type of reinforcement. The contents of the reinforcement settings will be discussed later.
    On the Framing holes tab there is also a preview field of the outline of the plate with the contours of the holes. The hole selected in the list on the left is highlighted in the preview field. You can also zoom and move the image, and the Zoom all command is available in the context menu of the field.

    There are buttons at the bottom of each tab:

    share variant (rotated)– allows you to copy the reinforcement settings of the current tab to the checked slabs (for the Slab Reinforcement tab) or checked holes (for the Hole Framing tab)
    content save – allows to save the current reinforcement settings as default reinforcement settings
    download – allows you to export the current reinforcement settings to an xml file
    upload – allows you to load reinforcement settings from a previously exported xml file of reinforcement settings

    Final settings and starting the reinforcement process

    In the row Create: you can specify what type of reinforcement will be created for checked slabs and holes: Basic (background) reinforcement, End reinforcement, Framing holes.

    In the processed slabs (Floor) a rebar cover ... – sets the option of setup a rebar cover in the processed slabs. When creating reinforcement, the rebar cover in the slabs is pre-set to 0 in order to avoid uncontrolled shear of the reinforcement when creating.

    Removal of previously created reinforcement – this option allows you to remove the reinforcement created by the plugin (reinforcement of the same type that is created or all previously created reinforcement), if you want to recreate it.

    Create reinforcement – start creating reinforcement of checked categories for checked slabs and holes.


    Slab reinforcement

    The settings are set for the single slab selected in the slab list on the left side of the plugin window.

    General reinforcement settings

    9

    In this group, the basic settings for reinforcement are set, which are used when creating any type of reinforcement

    Basic (background) reinforcement

    10

    In this group, the background reinforcement of the slab is configured.

    Create Reinforcement - allows you to disable the creation of background reinforcement in a particular slab, regardless of all other reinforcement groups.

    In all other groups, the checkbox Create reinforcement performs the same function - allows you to disable the reinforcement of a particular group in the current slab.

    If the Number of the background reinforcement meshes is set to 1, then creating a frame along the contour and the frame of the holes will be impossible!

    For background reinforcement, you can specify the orientation of the bottom mesh - co-directional or mirrored. The co-directional option cannot be used if all background reinforcement is created by a single instance of "Area Reinforcement".

    You can create background reinforcement with both Individual rebars and Area Reinforcement. If you select Area Reinforcement, you can create in four ways:

    • Use Area Reinforcement for Each direction in each mesh (i.e., with two meshes, four Area Reinforcement elements will be created)
    • Use Area Reinforcement for Each direction (i.e., with two meshes, two Area Reinforcement elements will be created)
    • Use Area Reinforcement for Each mesh (i.e., with two meshes, two Area Reinforcement elements will be created)
    • Use Area Reinforcement for Total background reinforcement. In this case, one Area Reinforcement element will be created.

    For created instances of "Area reinforcement" you can specify the size from the drop-down list. It is also possible to translate the values of string parameters of "Area reinforcement" into rebars.

    In all groups of reinforcement settings there is a button Parameters, clicking on which opens a dialog box for setting values of text parameters for the created reinforcement. The list of parameters is filled with the current document:

    18

    For the longitudinal and transverse reinforcement of the upper mesh it is necessary to specify the type and diameter of rebar bars, step and the offset of the outermost rod from the edge of the slab. It is also possible to add the creation of a filler rod at the edge of the slab (only on the outer edges) using the corresponding option.

    The longitudinal and transverse reinforcement settings of the bottom mesh can be set different from those of the top mesh by unchecking the option Bottom mesh reinforcement settings repeat the top mesh reinforcement settings.

    The main settings for reinforcement, as well as settings for background reinforcement, are taken into account when creating all other types of reinforcement, regardless of whether background reinforcement is created.

    REINFORCEMENT OF ENDS

    12

    Reinforcement of ends is carried out by creating U-shaped rebars with a background reinforcement step. Ends can be reinforced either completely, only longitudinally or only transversely using the option Create Reinforcement in the corresponding sections of the settings group.

    Detail length can be calculated by pressing calculator – a window will open with calculation of the length of the rod or the length of the anchoring according to SP 52-101-2003:

    15

    The option to limit the generated length is available below – if after generating the rod its length turns out to be less than the specified length, the rod will not be created.

    In case of differences in the steps of the background reinforcement meshes, it is necessary to select in the drop-down list how the U-shaped rebars step will be set by: rebars of top mesh or rebars of bottom mesh. It is also possible to set the Multiplicity of the step relative to the step of the rods of the background reinforcement (x1, x2 or x3) and to enable the option to Create each detail with a separate rebar.


    Framing holes

    The framing of the holes depends on the results of the analysis of the geometry of the slab. Highest Success Rate for Rectangular and Round Holes.

    Holes with sizes up to 300 mm are not framed. It is not possible to specify reinforcement for such holes and include them in machining.

    Holes with sizes up to 300 mm are grouped and processed as one if the distance between the boundaries of such holes is less than 100 mm.

    The settings are specified for the hole selected in the hole list in the left part of the plugin window.

    If you put the mouse cursor over the settings group of the Framing Holes tab, a pop-up window with the framing hole scheme appears, where the rebars whose settings are set in this group are highlighted in red.

    Straight rods in the longitudinal direction. Straight bars in the transverse direction

    The settings for creating straight rods are set separately for longitudinal and transverse directions:

    13

    Indent from the hole: – set from the edge of the hole to the middle of the reinforcing bar.

    Up to three rows of straight rods can be specified (each row has 2 rods "along" the hole). For the first row (closest to the hole) it is possible to enable checking and displacement when background reinforcement hits the rods, but this does not guarantee correct displacement of the rods from the second and third rows.

    LONGITUDINAL TIED STIRRUPS. TRANSVERSE TIED STIRRUPS

    To be able to create tied stirrups in the longitudinal direction, you must enable the creation of at least two rows of straight bars in the longitudinal direction with the option Displace when hit by reinforcement bars disabled in the previous group of settings. Similarly for tied stirrups in transverse direction.

    Settings for creating tied stirrups are set separately for longitudinal and transverse directions:

    19

    For the tied stirrups you can select Layout along the length of opening or straight bars. Layout of the tied stirrups in longitudinal direction along the length of the straight rods:

    20

    Create with a step of background reinforcement - when this option is enabled, the tied stirrups will be created with the rod tep of the top mesh of the background reinforcement. If the background reinforcement is not created in the slab, the tied stirrups will be created with the specified step.

    U-shaped rods in the longitudinal direction. U-shaped rods in the transverse direction

    The settings for creating U-shaped rods are set separately for longitudinal and transverse directions:

    14

    Diagonal reinforcement

    11

    Indirect reinforcement is performed at 45 degrees to the outer corners of the hole. When calculating the anchoring length, the length of the rods is specified as two anchoring lengths
