Allowable stress in concrete

Handling with the function is analogous to Checking of limit strain. The values offered for display are naturally different.

Values

Check value

The result of the check. The value of 1 means that the capacity is fully utilised.

sigma cc,max

Allowable stress of concrete prior and after anchoring/transfer of prestressing.

sigma cc,ch

Allowable stress of concrete in compression under SLS characteristic combination.

sigma cc,qp

Allowable stress of concrete in compression under SLS quasi-permanent combination.

f ct,eff

Allowable stress of concrete in tension under SLS combinations.

sigma c,aa

Stress of concrete after anchoring/transfer of prestressing.

sigma cq,min

Minimum concrete stress after application of self-weight, all permanent, and variable loads.

sigma clt,min

Minimum concrete stress caused by long-term loads.

sigma cq,max

Maximum concrete stress after application of self-weight, all permanent, and variable loads.

sigma clt,max

Maximum concrete stress caused by long-term loads.

sigma c,inc

Stress increment in concrete caused by selected load case.
