GRAITEC What’s new in Advance Design 2016 – SP1

MOVING LOADS GENERATOR

Advance Design 2016 SP1 features a brand new moving loads generator that enables the user to create traffic loads on road bridges according to EN1991-2 (Section 4).

In order to create the appropriate traffic loads on the road bridge (only on planar elements), ADVANCE Design expects the user to define the elements composing the carriageway: • One or several traffic lanes • Remaining areas • Footways or cycle-tracks


EN1991-2 defines imposed loads (models and representative values) associated with road traffic, pedestrian actions and loads on remaining areas (outside the lanes), which include when relevant, dynamic effects.


Divisions of the carriageway into notional lanes (§4.2.3) A specific “Carriageway” system must be created in the Pilot, using the contextual menu.

The Traffic Lane icon enables the user to define theoretical lanes. The lane determining the most unfavorable effect will be defined as Lane Number 1, the lane determining the second most unfavorable effect will be defined as Lane Number 2, etc.


The user can define the width for each segment along a traffic lane.

The Traffic Lane icon also enables the user to define the footways and cycle-tracks areas by activating the corresponding property:


The Traffic Panel icon enables the user to define the remaining area:


Application of the load models on individual lanes (§4.2.5) The user can now create a Traffic Load family:

The ‘Traffic load model’ field lets the user select one of the load models defined in §4.3 from EN1991-2.


ADVANCE Design 2016 SP1 features: • Load Model 1 (LM1): combination of a Uniformly Distributed Load (UDL) and four

concentrated loads (Tandem Systems or TS). LM1 covers most of the effects of car traffic. It should be used for general and local verifications.

• Load Model 2 (LM2): A couple of concentrated loads reproducing traffic effects on short

structural members. Load Model 2 represents a single axle of a truck and creates concentrated forces along the lane. LM2 is used for local verifications.


Depending on the National Appendix specified for the project, the Bridge Category parameter might be enabled.

The Carriageway definition dialog enables the user to define the loads to generate on each area of the road bridge (traffic lanes, remaining area and footways).


Clicking the ‘Auto’ buttons will automatically use the parameters defined in EN1991-2 regarding: • Load intensity • Wheel and axle spacing • Contact surface

The ‘Spacing’ parameter sets the distance between the various positions of the punctual loads.

The ‘Automatic generation’ command will create the corresponding loads on the model.


The various positions of the Tandem System on each lane are visible in the Pilot:


Envelope creation and combination with the other loadcases The various positions of the Tandem System will not be directly combined with the other load cases. In order to reduce the number of calculations, ADVANCE Design will automatically generate envelopes of forces to store the favorable/unfavorable effects of the concentrated loads on the carriageway.

These envelope loadcases will be combined with the other loadcases. The combinations involving traffic loads can only be generated using the ‘Detailed Combinations’ dialog.


Specific table for traffic loads A new table, describing the characteristics of the moving loads, is available:


MISCELLANEOUS IMPROVEMENTS AND CORRECTIONS

ADVANCE Design 2016 Service Pack 1 offers more than 140 improvements and corrections.

General application • Improvement: The combination grid has been improved so it is no longer limited to 5000

combinations (#16877). • Correction: Defining a haunch using the “z+” or “z-“ options for positioning no longer

leads to a crash when set to German language (#16807).

• Correction: A problem made Imposed displacements impossible to define (#16365).

Post-processing • Correction: Forces on linear supports displayed as vectors and as diagrams were

sometimes inconsistent (#16713).

Eurocode 1 • Correction: Wind forces on parapet walls were missing for duo-pitch canopies (#16550).

Eurocode 2 • Improvement: A new ‘Minimal longitudinal reinforcement’ property has been introduced

for both linear and planar elements. This allows the user to decide whether or not this minimum reinforcement should be taken into account (#16681).

Linear elements Planar elements


• Improvement: The ‘Reinforcement definition’ dialog has been rearranged and the three

tables are now the same size (#16803).

Import / Export • Improvement: The out-of-plane moment on top of a shear wall calculated in Advance

Design can now be exported to ARCHE Shear Wall (#16883). • Correction: End releases on linear elements were sometimes altered during .TXT or

.DO4 export (#16547).


Eurocode 3 • Correction: The Cmy,0 and Cmz,0 buckling factors were interverted. They are now

displayed in their appropriate buckling plane (#16789).

• Improvement: Global sway imperfections are no longer created in the plane where Ф =

0, in order to avoid generation of useless loadcases (#16262).

• Correction: The results from the fire analysis could not be displayed on some models

(#15287).


Eurocode 5 • Improvement: When a member is not submitted to a certain force component (for

example, traction), the shape sheet will show ‘Not performed’ for the corresponding check, instead of returning a 0% work ratio, which could confuse the user (#16863).

• Correction: The kh(N) dimension factor displayed in the simplified shape sheet could be incorrect (#16833).

NEW LANGUAGE

A new language is available for Advance Design 2016 SP1: Bulgarian.


CAD options available in ribbon • Improvement: the commands ‘Zoom’ and ‘Translation’ have been added to the ribbon.

Load generator • Correction: snow accumulation load value near a higher building (#16333).

Sectional characteristics • Correction: calculation of section characteristics for non-symmetric I parametric

sections => the plastic modulus was incorrect in some cases (#16727).


Post-processing • Correction: Advance Design can display values for efforts as ‘Values on grid’ (#16731)

Reinforcement area displayed as ‘Iso regions’

Reinforcement area displayed as ‘Values on grid’


Reinforced Concrete Design • Improvement: For planar elements, if the theoretical reinforcement area is smaller than

the minimum reinforcement area, Advance Design displays the minimum reinforcement area as theoretical area. Advance Design now eliminates the risk of under-reinforced areas, due to not taking into account the minimum reinforcement area (#16363).

The minimum reinforcement, for this situation, is 2.27 cm2, and only for the middle area, the theoretical reinforcement calculated based on FEM results is bigger.

• Improvement: For planar elements, Advance Design displays diagrams for both over-reinforced and under-reinforced areas, for differences between theoretical reinforcement and real reinforcement and for ratios between theoretical and real reinforcement areas (#16853).

This diagram shows over-reinforced areas in the planar element (under-reinforced areas are displayed with the value 0). The diagram will display only positive values (the difference between theoretical and real reinforcement is greater than 0).


This diagram shows under-reinforced areas for planar element (over-reinforced areas are displayed with the value 0). The diagram will display only negative values (the difference between theoretical and real reinforcement is smaller than 0).

• Correction: for 2D columns (plane mode), the minimum reinforcement is considered only on two faces of the column, and not on all four faces (3D mode) (#16806).

• Improvement: fire resistance can now have a specific value for every element (#16806).

Timber design • Correction: for combinations containing multiple variable loads, the instantaneous

deflection calculation must include only the dominant load. The instantaneous deflection is specific to a load, not to a combination, and is defined in EC5 as the deformation of the leading variable load (#16711).

Reports • Correction: FEM reports (with efforts and stresses on linear elements) take into account

the ‘Clipping’ option, if it is activated.

Export to Revit® • Improvement: FEM results (calculated in Advance Design) are synchronized with

Revit®.


• Improvement: Combinations are exported (using the gtcx format) from Advance Design

to Revit®.

• Correction: the user can import sections not currently included in the European Profiles

catalog.


Export to TXT files • Improvement: the sections and materials defined in a model will be purged when

exporting to .txt, if they are not used in the model. • Improvement: loads will be exported with their ID (for example, the punctual loads 3 and

4 are now exported in .TXT format with their no. 3 and 4).
