CONTINUOUS BEAMS AND SLABS ANALYSIS | DESIGN | DETAILING| CO1
Summary Design single and multi-span reinforced concrete beams and slabs, with rectangular, T, L, or I shaped, and inverted T and L-sections, as well as tapered sections. You can analyse sub-frames and the module automates the pattern loading of dead and live loads at ultimate limit state. Continuous Beam allows redistribution of moments and shear to a user specified percentage. This module can be used on its own or as a post-processor for Sumo . Generate complete bending schedules for beams and slabs.
What makes this module special?
• Automated pattern loading • Post-processing from Sumo • Generate complete bending schedules
Detailed Description Continuous Beam allows you to easily design multi-span reinforced concrete beams and slabs. Spans can be supported with or without rotational restraints, i.e., columns above and below. Sections that can be defined are rectangular, T, L, or I shaped, as well as inverted T and L-sections. Sections can be tapered along the span of the beam. The module can analyse sub-frames (including columns) and automates the pattern loading of dead and live loads. At ultimate limit state, moments and shears can be redistributed to a user specified percentage. Both short-term (elastic) and long-term deflections are calculated. The long-term deflection calculations consider concrete

cracking, shrinkage, and creep. For beams and one-way spanning slabs, you can manipulate long-term deflections by editing the steel reinforcement.
Continuous Beam can save a lot of time by conveniently using the module on its own or as a post-processor for Sumo . Using the Design Links, you can import beams complete with geometry, moment, and shear force envelopes for detailed design and reinforcement detailing. After the analysis you can generate complete bending schedules for beams and slabs. A 3D picture helps you position the bars accurately and identify any possible conflicts. The module automatically adjusts the reinforcement detailing rules according to the mode selected, e.g., beam or column strip of a flat slab. Using the rebar editor, it is easy to modify the main and shear reinforcement – diagrams display the entered reinforcement together with the required amounts at ULS and minimum amounts required by the design code. You can open the generated bending schedules in Padds or Probar 2D for final editing and printing.
Theory used in this module Entered dead and live loads are automatically applied as pattern loads during the analysis. At ultimate limit state, moments and shear are redistributed to a specified percentage. The module constructs a 2D frame model of the beam/slab and any specified columns. It performs analyses at SLS and ULS:
It uses the gross uncracked concrete sections in the analysis; separate adjustments are made for cracking in the assessment for long-term deflections.
The module can redistribute bending moments at ultimate limit state. It does this by adjusting the support moments downward with the specified percentage. If you set the method of moment redistribution is set to optimised , the module will further minimise the design moments by redistributing the sagging span moments upward as well. Shear forces are adjusted appropriately to maintain equilibrium.

CONTINUOUS BEAMS AND SLABS ANALYSIS | DESIGN | DETAILING| CO1
The various design codes follow similar proportions for dividing flat slabs into column and middle strips. The module follows a rational approach by using the column and middle strip proportions specified in BS 8110 - 1997, and then adjusting the strips widths to simplify reinforcement detailing.
Continuous Beam calculates elastic (short-term) and long-term deflections. In both cases, it uses the SLS loading with no moment redistribution. Adjustments are made for concrete cracking in the long-term deflection calculation.

Bending stresses and elastic deflection is calculated through a finite element analysis. When calculating the design bending moments, the module transforms the bending and torsional moments using the Wood and Armer equations. Theory used in this module The module calculates bending stresses and elastic deflection through a finite element analysis. Steel reinforcement is calculated using the formulae stipulated in the relevant design codes. Elastic short-term deflections are calculated using the gross uncracked concrete section of the slab. When calculating long-term deflections, the module adjusts the stiffness of the slab based on the level of cracking, creep, and shrinkage. The calculation procedure is based on the approach in the American design code, ACI 318, which uses a time-depended factor and for estimating creep behaviour.

What makes this module special?
Custom sections Evaluate column capacity for entered bars Generation of bending schedules
Detailed Description Design and detail concrete columns with any general shape. Enter the column outline and any openings, as well as the position and size of each longitudinal reinforcement bar. General Column designs columns that do not necessarily fall inside the scope of the codes’ simplified design method requirements. The module therefore reverts to basic principles, e.g., strain compatibility and equilibrium, to analyse columns. During the design, you have the option of evaluating the column capacity for the reinforcement bars as entered, or to calculate the minimum bar size required to resist the design loads. You can generate a reinforcement bending schedule that you can edit and print with Padds .
GENERAL COLUMN DESIGN ANY SHAPE OF REINFORCED COLUMN DESIGN | DETAILING | C13
Theory used in this module The section properties are calculated, and the column slenderness evaluated. For a slender column, the additional slenderness moment is calculated and applied about the weak axis. The output gives the X and Y axis components. The design moment and axis are determined by taking the vector sum of the applied and additional moments. An iterative solution is obtained using strain compatibility and equilibrium as criteria.

Detailed Description Retaining Wall is used to analyse concrete retaining walls for normal soil and surcharge loads or seismic load conditions. The module can design most conventional retaining walls, including cantilever, simply supported, and propped cantilever walls. Retaining Wall offers a host of input parameters allowing you to enter complex geometries like backward or forward sloping walls and toes, as well as walls that have a varying thickness though their height. Line loads, point loads, and distributed loads can be placed on the backfill. The module allows you to choose between the Rankine and Coulomb theories and can also incorporate seepage into the analysis. A water table can be specified; it may even be defined above the soil surface to model a liquid retaining wall. If required, the soil pressure coefficients can be adjusted manually. Retaining walls are checked for stability (overturning and sliding at both SLS and ULS) as well as for strength (flexure and shear at various positions in the wall and base). The most common use of the module is to analyse a wall with dimensions as entered. However, functions are available to optimise certain wall dimensions, e.g., the depth of the toe needed to resist sliding. The module uses the calculated design moments in the wall and base to determine the required reinforcement. Furthermore, generate a bending schedule that can be edited and printed with Padds or Probar 2D .

BEAM SECTION DESIGN OF CONCRETE BEAM SECTIONS DESIGN | C22
Detailed Description Use the Beam Section module to design a concrete section subjected to moment, shear, and torsion forces.
The design calculates moment, shear, and torsional stresses in web and flange, and required reinforcement for each.
Some reinforcement configurations are also suggested in the output as guidelines. The section design output can be grouped on a Calcsheet for printing or sending to Calcpad . Various settings can be made with regards to the inclusion of design results and pictures.
Theory used in this module The normal code formulae apply when calculating flexural reinforcement for rectangular sections and for flanged sections where the neutral axis falls inside the flange. If the neutral axis falls outside the flange, the section is designed as two separate sub sections: The first sub section consists of the flange without the central web part of the section and the remaining central portion defines the second sub-section. By considering the total section, the moment required to put the flange portion in compression can be calculated using the normal code formulae. This moment is then applied to the flange sub section and the required reinforcement calculated using the effective depth of the total section. The same moment is then subtracted from the total applied moment, the resulting moment is applied to the central sub section and the reinforcement is calculated.
BEAM SECTION DESIGN OF CONCRETE BEAM SECTIONS DESIGN | C22
The tension reinforcement for the actual section is then taken as the sum of the calculated reinforcement for the two sub sections. If compression reinforcement is required for the central sub section, it is used as the required compression reinforcement for the entire section. The module assumes that shear is resisted by the web portion of the section only. Shear stress is therefore calculated using the web area and checked not to exceed the ultimate allowable shear stress given in the code. The shear capacity is calculated using the required bending reinforcement and the shear reinforcement calculated using the normal code formulae. Depending on the option chosen, torsion can be resisted by the section as a whole or by the web portion only. For flanged beams, the torsion is calculated separately for the flange and web along the guidelines given in the code. The torsional shear stresses are checked to not exceed the ultimate allowable shear stress. Reinforcement requirements are also evaluated separately for the flange and web using the normal code formulae. For the Eurocode, the strut-and-tie model is used, and the angle of the struts can be specified within the limits of the code.
