Analysis, grouping and reinforcement of slabs for specified conditions
About files with the extension .mpif
The file with the .mpif extension is a special installation file of the ModPlus (ModPlus Install File).
These files allow you to install and update all ModPlus components using the auto-update module
in case you do not have access to the internet or modplus.org
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

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.
There are options in the window title:
||– opens the window for setting preferred shapes of rebars:
The drop-down lists in this window are filled with shapes from the current open document.
||– general plugin settings:
In the group Reinforcement by default you can specify the reinforcement settings that will be set for slabs by default
Select – opens the slabs selection window:
Only slabs with the enabled property Structural get into the filtering of the selection.
Analysis – start analysis of geometric and parametric data of selected slabs, including hole analysis.
Important! 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.
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:
||– 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)
||– allows you to export the current reinforcement settings to an xml file
||– allows you to load reinforcement settings from a previously exported xml file of reinforcement settings
In the row Create: you can specify what type of reinforcement will be created for checked slabs and 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.
Delete reinforcement previously created by the plugin – this option allows you to remove the reinforcement created by the plugin, if you want to re-create it.
Create reinforcement – start creating reinforcement of checked categories for checked slabs and holes.
In this group, the basic settings for reinforcement are set, which are used when creating any type of reinforcement
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 meshes of the background reinforcement is set to 1, then creating a frame along the contour and the frame of the holes will be impossible!
You can create background reinforcement with both individual rods and Area Reinforcement. If you select Area Reinforced, you can create in three 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 the entire background reinforcement. In this case, one Area Reinforcement element will be created.
Attention! In all cases, except for creating the entire background reinforcement with one element of Area Reinforcement, the location of the longitudinal and transverse reinforcement in the upper and lower mesh relative to each other is the same. When creating background reinforcement with one Area Reinforcement element, the location of the reinforcement of the upper and lower mesh is mirrored
You can set various settings for the longitudinal and transverse reinforcement of the upper and lower mesh.
Attention! 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.
End reinforcement is carried out by creating U-shaped rebars with a background reinforcement step.
Calculate the length of the U-shaped rebar – hereinafter - calculation of the length of the rod or the length of the anchoring according to SP 52-101-2003:
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.
Indent from the hole: – set from the edge of the hole to the middle of the reinforcing bar.
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
