Concrete Beam

Analysis and design according to Eurocode for continuous beams. Based on the moments and shear forces calculated in the analysis part; required longitudinal reinforcement and stirrups are determined. Optimization of required reinforcement lengths with regard to bond can be made graphically. In the Serviceability Limit State a cracked section deflection analysis is done and a design regarding crack widths and displacements to meet standard- or user defined requirements can be performed. Alternatively, cracks and displacements can be calculated based on specified reinforcement.

Go to the tab Calculation Instructions for an example guide on how to use this WIN-Statik program.

After defining the adequate input an analysis is performed producing the section forces.

 


 

In the next step a design for the Ultimate Limit State is performed according to Eurocode EC2 and the required bending and shear reinforcement are displayed graphically along the beam as well as at chosen sections.

 


 

And represented in tables. If minimum requirements are decisive the selected reinforcement will be according to these.

 


 

If curtailing of the bars is required it can be done graphically where the length of the bars is adjusted with regard to the displayed tensile force curve.

 


 

The next step is to check the beam in the Serviceability Limit State with regard to crack width and deflections.

 


 

Deflections with regard to cracked sections are displayed graphically for total load, long time load and as a comparison also for the un-cracked state.

 


 

Max crack widths and their location as well as deflections along the beam are displayed as tables together with detailed result for the Serviceability Limit State.

 


 

If crack widths and/or defections are too large it is also possible to perform a design also for the Serviceability Limit State.

 


 

The user defines an allowed max crack width limitation and an allowed max deflection limitation and the program will increase the reinforcement until these limitations are met if possible.

 


 

As an alternative the user can manually increase the reinforcement at certain points to see which effect this has on crack widths and deflections.
Finally when the results are satisfactory the output can be sent to a printer.
