B11 | Crack Width Verification | Update Information


Version 02/17


Correction

Program crash while reading ASCII file fixed.


Version 01/17


Correction

The output profile can be saved now.


Version 02/16


Eurocodes

BS EN 1992:2015 and DIN EN 1992:2015 implemented.
Design with early constraint: The dafault for fct,eff is changed to 0,65 * fctm.
Following a recommendation in Beton-und Stahlbetonbau 3/2015 p.183 is for the German Annex for slow hardening concrete possible reduction of the reinforcement for Eq. 7.1 and the left part of Eq. 7.5.1DE no longer recognized.


Version 01/16


Correction

English language settings: Crash when lower deviation the minimum reinforcement. Issue is fixed.


Version 02/15


Addition

Preset design standard can be defined in the project properties.

Correction

User interface and output results representation corrected.
Item template functionality reactivated.


Version 01/15


Correction

For the calculation of the constraining force in floor slabs due to bottom friction is just used the design value of the friction coefficient , the recommended safety factor is 1,35.

Addition

New Version of the National Annex for United Kingdom and Germany implemented:
BS EN 1992:2009 and DIN EN 1992:2013.


Version 01/13B


Correction

Output for minimum reinforcement for centric indirect action in the case of a bottom flange was missing.
An in durability dialogue changed diameter on bottom side was not included in the proofs of minimum reinforcement.


Version 01/13A


Correction

In case of DIN EN 1992-1-1 exposure classes for alkali attack have been added.

For the Check of foundation plates with centrical restraint the issue of Asu was added.

The Output for printer was improved for the sections material and durability.


Version 01/13


Correction

Inputview:
Reinforcement with 2 decimal places as in the outputview

Output view, Minimum reinforcement at centric restraint:
crack width now with 2 decimal places, steel stress was with a factor of 10 too small

new position:
Error in standard selection was eliminated

Addition

DIN EN 1992-1-1/NA Berichtigung 1:2012-06
ÖNorm B 1992-1-1:2011-12-01

Version 02/11B


Correction

Option shorttime load was not saved for foundation plates.


Version 02/11A


Correction

Display of wk and Ds in the input view was with factor 10.
For evidence of hydration for floor slab and wall in new position now that short-term exposure is not activated.
For details and the new detection method on wall now see in B11-help, first chapter, notes for the new version 02/11.


Version 02/11


Extension

Extension

verification according EN 1992-1-1, annexes of Germany, Austria, Belgium, Netherlands, Czech Republic and United Kingdom.
verification wall on foundation: new procedure according the textbook of lohmeyer 9. edition


Version 01/11A


Correction

DIN 1045-1 (2008), minimum reinforcement centric train:
Minas in Equation 127 was exceeded.


Version 01/11


Correction

in strain determination was the time factor for the E-module was not considered

Extension

internal adjustments


Version 01/13B


Correction

Minimum reinforcement for T-beam cross section:
- An amended diameter of the bars on the side of the plate was not taken into account for this check.
- At centric restraint and plate on the bottom side was not issued Minas for the plate
- At centric restraint and plate on the top side MinAs was determined with kc < 1.0 something too small,
the formal output of this line has been corrected
