CONCRETE is an RSTAB add‑on module for reinforced concrete design of member elements. It provides options for the evaluation of RSTAB internal forces in various design cases. In this way, it is possible to quickly calculate alternative designs using different concrete strength classes or modified cross‑sections. The design is carried out for uniaxial and biaxial bending with axial force as well as shear and torsion. The corresponding extensions enable the design according to the following standards: • ACI 318‑14 (requires ) • CSA A23.3 (requires ) • EN 1992-1-1:2004 + A1:2014 (requires ) • DIN 1045‑1:2008-08 (requires ) • SIA 262 (requires ) • GB: Code for Design of Concrete Structures, 1st edition, July 2011 (requires ) Optionally, it is possible to perform fire resistance design for rectangular and circular cross‑sections according to: • EN 1992‑1‑2:2004 (requires ). After opening the program, you can define the standard and method according to which the design is performed.

The ultimate and the serviceability limit state can be designed according to the linear and the nonlinear calculation method. Load cases, load combinations or result combinations are assigned to different calculation types then. In other input windows, you can define materials and cross‑sections. In addition, it is possible to assign parameters for creep and shrinkage.

Creep and shrinkage coefficients are directly adjusted, depending on the age of the concrete. Support geometry is determined by means of design‑relevant data such as support widths and types (direct, monolithic, end, or intermediate support), redistribution of moments as well as shear force and moment reduction. CONCRETE recognizes the support types from the RSTAB model automatically. A segmented window includes the specific reinforcement data such as diameters, the concrete cover and curtailment type of reinforcements, number of layers, cutting ability of links and the anchorage type. In the case of the fire resistance design, it is necessary to define the fire resistance class, the fire‑related material properties as well as the cross-section side exposed to fire. Members and sets of members can be summarized in special 'reinforcement groups', each defined by different design parameters. You can adjust the limit value of the maximum crack width in the case of crack width analysis.

Before the calculation starts, you should check the input data using the program function. Then, the CONCRETE add‑on module searches the results of relevant load cases, load as well as result combinations. If these cannot be found, RSTAB starts the calculation to determine the required internal forces. Considering the selected design standard, the required reinforcement areas of the longitudinal and the shear reinforcement as well as the corresponding intermediate results are calculated.

If the longitudinal reinforcement determined by the ultimate limit state design is not sufficient for the design of the maximum crack width, it is possible to increase the reinforcement automatically until the defined limit value is reached. The design of potentially unstable structural components is possible using a nonlinear calculation. According to a respective standard, there are different approaches available. The fire resistance design is performed according to a simplified calculation method in compliance with EN 1992‑1‑2, 4.2. The module uses the zone method mentioned in Annex B2. Furthermore, you can consider the thermal strains in longitudinal direction and the thermal precamber additionally arising from asymmetrical effects of fire.

After the calculation, the module shows clearly arranged tables listing the required reinforcement and the results of the serviceability limit state design, including all intermediate values. In addition to the tables, current stresses and strains in a cross‑section are represented graphically. The reinforcement concepts of the longitudinal and the shear reinforcement including sketches are documented in accordance with current practice. It is possible to edit the reinforcement proposal and to adjust for example the number of members and the anchorage. The modifications will be updated automatically. A concrete cross‑section including reinforcement can be visualized in a 3D rendering. In this way, the program provides an optimal documentation option to create reinforcement drawings including steel schedule.

Crack width analyses are performed using the selected reinforcement of internal forces in the serviceability limit state. The result output covers steel stresses, the minimum reinforcement, limit diameters, the maximum bar spacing as well as crack spacing and the maximum crack widths. As a result of the nonlinear calculation, there are the ultimate limit states of the cross‑section with defined reinforcement (determined linear elastically) as well as effective deflections of the member considering stiffness in cracked state.

RC slab deflections in Robot according to BS 8110. RC slab deflections in Robot according to BS 8110. I have ran the reinforcement design in robot, but would like to extract the design data from robot and use it to produce a detailed crack width calculation, I will complete this on a excel sheet we use in the office. My intension is to use the various functions in the Robot addon, spreadsheet calculator (SC) to take the relavent data from my robot model and use it in this spread sheet. What I was looking at doing was trying to extract things like reinforcemnt diameters, fyk for steel etc directly from the robot model and into my crack width spreadsheet so that when the design was completed on Robot it could be cross checked and a detailed design calc could be produced also. Do you have a copy of the SDK for robot so make it easier for us to extract the relavent data.

We have a copy Kong and Evans, which I have now researched and will use this as the basis fo my detailed calculation in SC. I note there has been a request for a 'RC slab deflections in Robot according to BS 8110' but according to EC 2 could you provide that as I wish to update our system here to EC 2 and that would help in the transition. Once again thank you for all the assistance it is a great help. Best regards Gavin.

Ad1 Yes,„Long term deflection (t=inf) due to quasi-permanent combination” Ad2 Deflection as described: EN 1992-1-1:2004 7.4.1 (5) Deflections that could damage adjacent parts of the structure should be limited. For the deflection after construction, span/500 is normally an appropriate limit for quasi-permanent loads. Other limits may be considered, depending on the sensitivity of adjacent parts. (Long term deflection increase depends on QPR loads after building errection) Ad3 long term cracks: EN 1992-1-1:2004 7.3.1 (5) A limiting calculated crack width, w max () it may be assumed that limiting the calculated crack widths to the values of wmax given in Table 7.1N, under the quasi-permanent combination of loads.

Mirko, First part of answer - cracks (basing on model and documents you sent me): In fact rebars are loacated 2mm beloww the level you assumed: but it does not give significant difference. According to your book example explanations, our understanding of Slovenian language + googletranslate. We see this we understood that c is calulated as d - 1/2*rebar_diam - transversal_rebar_diam so it is cover to transversal rebar But according to EC2 7.11 so this difference gives srmax 209mm instead of 190mm and thus 0.25mm cracks instead of 0.22mm. .it's Croatian language, not Slovenian. They are similar but very different.;) we understood that c is calulated as d - 1/2*rebar_diam - transversal_rebar_diam so it is cover to transversal rebar That's correct.

But according to EC2 7.11. Yes, I've cheked in my Croatian version of EC2, that correct too. I didn't pay attention to it before. Usually, when we calculate reinforced concrete, and someone says cover 'c', we all assume that's distance from face of concrete to the first reinforcement bar. This may be an error. I will check this with the author of the book. Thank you very much Rafal!

Hope to see the rest of it soon. The Distant Future Ep Zip.
