AD.2007-1001.4.1 Beam and Column Designs to the Russian Concrete Code SP52

Two new design options have been added that allow concrete beams and columns to be designed to the Russian Concrete design code SP52-101-3.

The Russian Design Codes are only available with the Euro-zone – Eastern Design Codes SELECT license.

The SP52-101-03 design checks are initiated by creating a design brief based on this code. This option is now available and can be selected when creating a new design brief. Beams and columns can be designed using design briefs tailored to the requirements of the specific item.

Design Briefs are created in the Design Layer | Groups/Briefs Page of the Concrete Designer mode. Click on the New Brief button on the base of the Design Brief Table:

Beam Design Briefs

An SP52 Beam design brief is created by setting the design brief options in the dialog that is presented when the New Brief button is clicked on the Design Briefs dialog:

The beam design brief contains two sheets of data that are used in the calculation of the reinforcement of any member that it is associated with. Default values are provided which should be changed to the specific values required for the design. These sheets are titled ‘General’ and ‘Reinforcement’ thus:

Column Design Briefs

An SP52 Column design brief is created by setting the design brief options in the dialog that is presented when the New Brief button is clicked on the Design Briefs dialog:

The column design brief contains three sheets of data that are used in the calculation of the reinforcement of any member that it is associated with. Default values are provided which should be changed to the specific values required for the design. These sheets are titled ‘General’, ‘Reinforcement’ and ‘Member Loadcases’ thus:

With the Design Brief created, Design Groups must be defined. These are created by selecting the design members that are required and clicking on the New Design Group button on the base of the Design Groups dialog:

This pops up a dialog to allow the required Design Brief to be assigned to the selected design members that are now in this Design Group.

The group is added to the Design Group table and by double clicking on the group label, e.g.G1, then the list of members in the group is displayed and can be edited.

Note from here on, a suitable license is required to perform a design or review the results of a design.

To perform a design or review results of a previous design, requires entering the Concrete Member Mode by either clicking on the tab on the left of the screen or selecting Member Design from the Mode menu.

The program uses the Design Brief of the current Design Group to determine the page tabs and page layout that is now presented. The current Design Group is selected by choosing it from the drop-list of design groups displayed at the top of the screen:

Beam Designs

When the current group has a beam design group associated with it, entering the Concrete Member Mode, there are the following 7 pages:
  • Summary
  • Design
  • Main Layout
  • Main Reinforcement
  • Shear Layout
  • Shear Reinforcement
  • Cracks

The Summary Page displays the current status of the design of the members in the design group in a Summary table. Each member is identified with the principal checks including the span and section where the maximum utilization occurs. If any section cannot achieve a solution such that the design ratio is greater than unity, this is identified in red, thus:

The Design Page is laid out in the same manner as the Summary Page but also launches the Design options dialog, where members from the design group can be selected or removed from the design process:

The Main Layout Page displays the design reinforcement for the current member selected from the design group drop list:

Note that the section arrow displayed on the elevation of the beam or the moment diagram, can be moved to display the reinforcement at any location along the beam.

By clicking on either the beam elevation or the cross section, then clicking on the ‘Take Picture’ toolbar icon, a picture will be added to the picture album which can be included in a User Report:

The Main Reinforcement Page displays the summary of the calculations at each of the design sections for both the maximum positive and negative moment at the given section for the current member.

The Shear Layout Page displays the shear reinforcement for the current member:

The Shear Reinforcement Page displays the summary of the shear reinforcement calculations at each cross section for the current member.

The Cracks Page displays the summary of the crack width check for both short and long terms and both maximum hogging and sagging moments:

Column Design

When the current group has a column design group associated with it, entering the Concrete Member Mode, there are the following 6 pages:
  • Summary
  • Input
  • Design
  • Main Layout
  • Results
  • Drawing

The Summary Page displays the current status of the design of the members in the design group in a Summary table. Each member is identified with the bars provided and a safety margin, thus:

The Input Page provides a table to set the effective length factors (enter b to reset to the value set in the brief), an indication as to whether either direction is braced and what size link bar is to be used thus:

The Design Page is laid out in the same manner as the Summary Page but also launches the Design options dialog, where members from the design group can be selected or removed from the design process:

The Main Layout Page displays the reinforcement layout in the column, including the shear links. For a typical rectangular or square column it is shown thus:

For a circular column it is shown thus:

The Results Page displays a table of the principal check for each column in the group thus:-

The Drawing Page allows the current column details to be exported into a DXF file that can be used imported into a CAD package. Also a simple summary schedule of bars for the current member is displayed.

Exporting to Bentley Rebar

Both beam and column designs can be exported to Bentley Rebar by selecting the menu option, Groups > Export Group to Rebar.
