Design of monolithic rib-reinforced floors

The application Monolit is intended for designing ferroconcrete monolithic finned floors formed by a complex of panels and beams supported by columns and (or) walls. The software has been developed in compliance with requirements of regulatory codes currently in effect (SNiP 2.03.01-84* "Concrete and ferroconcrete structures", GOST 21.501 - 93. System of project documentation for construction. "Concrete and ferroconcrete structures." Working drawings, GOST 21.101 - 97. System of project documentation for construction. "Main inscriptions.").

Floor design

General design of a panel is arranged on an orthogonal grid of nodes sequentially numbered. The nodes are located on cross-sections of structural elements of the floor – beams, walls, columns. Floor panels of constant thickness are considered to be positioned level with the upper face of the beams. Beams of rectangular cross-section (tee-shaped with a web near the upper face) can be divided into secondary beams loaded by a uniformly distributed load from the floor panels, and principal beams carrying the load from the secondary beams of lateral direction. Supports of the floor are load-bearing walls of the structure and (or) columns of its site-cast frame. Support conditions for the floor are determined by the walls material: brick-built walls define a simple moment-free support of beams and panels whereas concrete walls are stiffly connected to the floor and thus define a rigid moment joint between the beams and the plates, on one side, and the supporting structure. All load-bearing elements of the structure (walls, columns, beams) may be eccentrically positioned as related to axes between nodes of the coordination grid.

Grids and welded mats

This version of the application enables reinforcing constructions with welded reinforcement mats or grids made via spot welding of bar connections.


The result of the application work is a necessary set of working drawings of a floor panel with characteristic sections: shutter plan view with characteristic sections, plan views of the upper and lower reinforcement of the panel (layout of reinforcement grids), reinforcement drawings of beams, drawings of welded reinforcement mats and grids used for reinforcing panels and beams, bill of details, bill of steel consumption by beams, panels and overall one, specifications of beams, panels and overall one; necessary comments and notes are given. The subsystem provides complete unification of reinforcement products.

Output documents

All output documents are prepared in the standard format A4 used by most printing devices. Though, you can output them to devices of other formats, including Plotter.

To rework your output documents, exporting results to DXF formats – AutoCAD files – can be used.


Monolit operates under the Windows Vista/7/8/10 operating environment. User dialog techniques and controls conform to those common for this system.
