User interface

Programs IDEA StatiCa were transferred into the new graphic design. IDEA StatiCa definitively leaves the look of 90-thies, which is still typical for majority of FEA and CAD programs on the market.

User interface

User interface

The drawing of joint in 3D view is now active. Items of joint are highlighted when the mouse is moved over them. The explanatory text in bottom part of window is shown.
User interface

When clicking on highlighted item the appropriate manufacturing operation is found and set as
current. User can work with complex joints much easier and editing is simple.

All manufacturing operations are now equipped by explanatory dimensions. Dimensions are shown
for current operation. User works with property dialog of operation and directly see the result in 3D
window.

User interface

Edges of plates are numbered in operation “general weld”. Weld can be defined much easier.
User interface

Setting of units and out format of numbers was required by many users. Units can be set and number of decimal digits can be defined. Imperial units were introduced.
User interface

The formats of numbers in all forms and tables can look like this:

user interface

Some user claimed difficulties during input of loads. Orientation of force was not clear. Presentation
of local coordinate systems helps a lot.

Loads

The work with loads was remarkably simplified in version 6.Feedback from more users told us that more of them hesitate about the necessity to “have the joint balanced“. The requirement of equilibrium is fully correct, but especially for simpler joints is not necessary. There is one bearing
member in the joint and the others are connected to it. If we are interested only in investigation of connection of other members, the requiring of equilibrium is not needed. We introduced two modes in version 6:

  • Simplified – bearing member is fully supported (continuous member on both ends) and loads are not input on it at all.
  • Advanced (precise with equilibrium). Bearing member is supported on one end, loads are input on all members and it is necessary to balance all forces to reach equilibrium.

Modes are switched on ribbon:

load inputs

Tables in both modes for following example are enclosed:
load inputs

In some cases the actual position of the connection does not respect the position in the theoretical
joint. Then it is possible to move the calculated internal forces into the corresponding section. A new
"Copy position x" facilitate the work of a larger number of defined load cases.

Output report

IDEA Connection provides quality 3D presentation of calculated result quantities. Now we can insert
these pictures into output report.

Output report

Report was improved with all data about analysis and check settings. Everything is documented not only for designer, but also for checkers.

Output report

More users complained about missing data of base plate and anchoring. They all are now in a new table “Foundation block”.

Output report

CBFEM method is efficient and provides high quality results. However, for some less-informed participants of the design process (investors, checkers) may be unfamiliar or less clear. We have added an option to add into the printout report a chapter with the theoretical background of the method. It depends on the decision of the designer if he wants to have it in the protocol or not.

Welds

A big debate among users of version 5 about the work with welds was held. Most demanded greater generality in defining the welds in the joint. We have developed a new editing tool that allows defining the thickness, material type and welding on one line of property dialog.


It is now possible for each individual weld set the following types:

• Fillet weld one-sided
• Fillet weld duplex
• Butt weld -the weld creates a connection between the sheets, but it is not checked
• No weld -the designer may decide if the weld is in the joint or not. For example, on the I-beam its flanges may be welded and the web not.

saldature

Welds are checked according to standard component method and Eurocode. CBFEM provides the exact values of all welds in the joint. This is true since the first versions of the program. However, engineers demanded that they would like to know about the stress and forces in welds more. In version 6, we have added the pictures of the weld forces for each individual weld.

saldature

In addition, we introduced a new method of interpolation the stress in weld. The designer can choose if welds to check:

• The maximum calculated stress
• Averaged constant stress over a weld length (plus and minus is taken into account)
• Linear interpolated course of stress.

Operation “common weld" now allows you to define weld between the plate and the edge of another plate, but also directly between the edges of two plates.

Manufacturing operations

Version 6 now supports properly circular hollow sections (CHS) in all operations. Cut „tube by tube“ allows to handle the whole new class of tasks. Both tubes has to be circular.

operazioni di produzione

Functionality of CHS was completed also from the point of view of end and base plates. Radial groups of bolts are supported. Also stiffeners and ribs can be applied on CHS as well. These improvements make functionality much wider not only for anchoring of columns, but also in structures like offshore.

Gusset plates for connecting of hollow sections can be doubled now – either gusset plate or connecting plate on the lid.

operazioni di produzione

We modified the operation Opening, which can be used also for notches. Opening can be moved partially out of plate and notch is created. User can also add rounding into rectangular opening and notches.

operazioni di produzione

User can find more options for welded connections in gusset plates.

operazioni di produzione

Anchoring into walls can be done also for inclined beams or columns.

General cross-section

The module IDEA CSS was attached as an option to input a cross-section of IDEA Connection. It is now possible to work with the general composed and welded profiles. All rolled sections and plates can be a part of the cross section.

Stiffness of member connection

The first method of member connection stiffness analysis was implemented in version 5 of IDEA StatiCa. Method was good for simple joints composed from 2 members, but for more complex joint was not satisfactory and needed to much experience of the user. We replaced it by new one, which is not limited by complexity of the joint.

Two modes of analysis were introduced -Stress/ Strain and Stiffness.

Stiffness of member connection

In case of “Stiffness” settings the program is switched into special mode. Special analysis model is defined, where all members are supported except of investigated one.

Setting of analyzed member is done in Geometry. Analyzed member is set instead of bearing member in case of standard Stress/Strain analysis.

Stiffness of member connection

Checks are limited in “Stiffness“ mode and program offers only basic overview and the appropriate table of member stiffness and classification.

Enhanced version

Enhanced version offers several functions which are not available in Expert edition:

 

  • Analysis of the stiffness of connection of member to the joint
  • Analysis of local buckling of the joint
  • Usage of general cross-sections
  • General cuts (intersections) of circular hollow sections
