Improvements in Geotechnical Design - New options in design of retaining walls

Point of application of earth force in seismic design according to EN1998-5 par. 7.3.2.3. (4) and (5) this is from 1/3 to 1/2.

In foundations of steel columns, the water depth over the foundation level has been added.
This affects the footing self weight.

In footings of steel columns an additional horizontal force for uplift conditions has been added.

In retaining walls you have the selection to use separatelly reinforcement for the base and the top of the wall. The basement is casted first with reinforcement dowels over the foundation.

New features in BETONexpress 07.11.2016

Set specific reinforcement

Some times, in concrete elements the reinforcements chosen by the program to satisfy the design in Ultimate Limit State (ULS), is not enough for the max crack or max deflection criteria of in Serviceability Limit State (SLS). To take this into account, a new option has been added.  

In all the design objects: plates, beams, columns, footings, retaining walls, you can now specify the desired reinforcement.

If you do not check the Set specific reinforcement, the program computes the reinforcement as usual.
If the box is checked, you can specify the reinforcement more than needed for maximum moment in ULS. This reinforcement is used for the additional checks in Serviceability Limit State (SLS), and reinforcement schedules. 

Punching shear for pates and flat slabs 

Option for circular columns

Soil bearing capacity in fundaments and retaining walls 

If the box EC7 Annex D is checked, the soil bearing capacity is computed from Annex D of Eurocode 7. The computations are done simultaneously as you change the dimensions of the structure.
 

Columns Crack width calculation 

If the box Calculation of crack width is checked, the crack width wk is calculated. The load in SLS is computed from the Loading ration (ULS/SLS).

Cost of Upgrade 120 Euro. We will contact all our customers by e-mail.
When you request the new version you will receive a new address for the Upgrade.

If you update your BETONexpress from the main menu the ordinary way, you will not install the new version 07.11.2011, but the previous version before the latest upgrade.  

BETONexpress can also run as a post processor of various Finite Element Programs (ANSYS, SAP2000,) to perform the concrete element design. The communication of BETONexpress with other programs can be done with a command file in simple text format. Each line of this Command line file describes an object that is going to be created in BETONexpress. Commands and data can be read in BETONexpress and the design objects are automatically created. The format of the command text file is described here.  Also in Annex of new User Manual.

New features:

• Limits for redistributed moments in continuous beams and plates, EN 1992-1-1 :2004, 5.5 (4).
  e_uk is needed to classify the steel at A,B,C classes, Eurocode2, Annex C. This new version is containing the default values for e_uk, but you must then reset the values of steel propertiers. Go to [Parameteres/reinforced steel properties], click on [Locked] to unlock, then [Reset] to take the new steel properties. This wil not reset other material properties of the program.  

• Shear check for plates.

A new version of BETONexpress for concrete design adapted to the latest versions of Eurocodes is available.

Cost of Upgrade 120 Euro. We will contact all our customers by e-mail. If you request the new version you will receive a new address for the Upgrade.

If you upgrade your BETONexpress from the main menu the ordinary way, you will not install the new version 03.02.2007 with EN adaptions and automatic generation of CAD drawings. If you request the new version you will receive a different address for the Upgrade.

The new version includes all previous options.

New in BETONexpress Version 03.02.2007

For concrete design Eurocode 2, EN 1992-1-1:2004, Design of concrete structures, General rules and rules for buildings.
For geotechnical design, Eurocode 7, EN 1997-1:2004, Geotechnical design – General rules.
For concrete design you can now choose Eurocode 2, EN 1992-1-1:2004 or (EC2) ENV 1992 Design of concrete structures.
For geotechnical design you can choose Eurocode 7, EN 1997-1:2004, Geotechnical design – General rules or (EC7) ENV 1997 Geotechnical design

To install this version, enter BETONexpress/Update. .

Save to disk and unzip to where the program is already installed. 

This upgrade is still based on the ENV version of Eurocode 2. The upgrade is free of charge.

After the upgrading, when you first run the program again, we advise you to go to the menu Parameters/View parameters settings and click on [RESET to all original values] in order to reset to the new default values.

For old files you have to recompute the design objects.

 In this version, Ver. 05.11.06, following improvements and additions are done: 

• Automatic calculations as you alter the input data, and direct preview of full report.

• New design of reports, with alignment of the references at the right of the page. (this option can be canceled from Report setting/Paragraphs/Align references at right.)

• Reinforcement schedule is added in the end of each design object in the report. (this option may be canceled from Report setting/Graphic etc../ include rebar schedule in report)

• Export of report with drawings to PDF and Word files.

• You can select units for the rebar representation in the report from Setup/Units in report.

• You can adjust the rebar weight from Reinforcing steel properties/Weights.

 Plates
