Update history
CYPE 3D
- Check for shear buckling
Within the shear checks carried out by the program, an additional check for shear buckling has been implemented for when the section web is slender. - Check for shear and bending
When the shear effect in the calculation of the design bending moment is negligible, a justification text is generated. - Bending checks of elements
When lateral buckling is negligible, a justification text is generated. - Torsion, shear, axial force, and biaxial bending checks of elements
When the combined effect of torsion and shear is negligible, upon calculating the normal design forces, a justification text is generated. - Check for torsion
The calculation of the plastic torsional modulus has been included in the checks for torsion, so a more precise analysis is carried out. - Sections with Iz > Iy
It is now possible to check sections whose inertia in its Z-axis is greater than that of its Y-axis.
Code for Structural Design in the Republic of Panama (REP-04)
Implemented in CYPECAD and Metal 3D.
Algerian Seismic Loading Code RPA 99 / VERSION 2003 (Algeria)
Implemented in CYPECAD and Metal 3D.
- The number of codes is increased for which the detailed check reports on ultimate limit states of welded and rolled steel sections are obtained. These reports are available for the following codes and steel types:
- Rolled and welded sections:
- CTE DB SE-A (Spain)
- CAN/CSA S16-01 (Canada)
- Eurocode 3 (Generic, Bulgaria and Portugal)
- Eurocode 3 (France) - NF EN 1993-1-1/NA: 2007-05 (newly implemented)
- Cold formed steel sections
- NBR 14762 (Brazil)
As of the 2009.1.g version, users may introduce a value for the rotational stiffness at the ends of elements using the Fixity at ends option, located in the Bar menu. Metal 3D calculates the initial rotational stiffness of elements fixed to bolted connections which have been designed and displays them in the Joints report so users may compare the value to that introduced.
As of the 2009.1.j version, Metal 3D compares the rotational stiffnesses introduced by the user and those proposed by the program, and displays the comparison in an agile and efficient way using the Rotational stiffness option located in the Joints menu. This option allows the user to automatically assign the rotational stiffnesses proposed by the program as well as review them to decide which rotational stiffnesses to adopt.
We have augmented the number of building codes for which you can now obtain USL calculations for both rolled and welded steel members. The calculations are available for the following building codes:
- Rolled and welded steel members:
- CTE DB SE-A (Spain)
- CAN/CSA S16-01 (Canada)
- Eurocode 3 (Generic, Bulgaria, and Portugal)
- Cold formed steel members:
- NBR 14762 (Brazil)
We have recently implemented the following building codes:
- Seismic Codes:
- Decree #2, 23.07.2007 (Bulgaria)
- CSRC-2002 (Costa Rica)
We have recently implemented the following building codes:
- Concrete Codes:
- ACI 318M-08 (USA)
- CIRSOC 201 - 2005 (Argentina)
- Eurocódigo 2 (Bulgaria)
New bolted connections
- Beam joint type: a main continuous element to which one or two orthogonal elements are pinned to it.
- Two beam connection (with or without a bottom haunch) fixed to the flanges of a column (continuous or non-continuous).
- Two beam connection (with or without a bottom haunch) fixed to the flanges of a column (continuous or non-continuous) with an orthogonal beam pinned to the web of the column.
- Two beam connection (with or without a bottom haunch) fixed to the flanges of a column (continuous or non-continuous) with two orthogonal beams pinned to the web of the column.
New options for connection design
- Stiffeners at haunch ends
Stiffeners may be used at haunch ends in column-beamconnections and at ridge connections even though they may not be required in the design calculation. These two options can be activated in the Options dialogue (Joints > Options) which now contains two tabs:- Bolts: Contains bolt design options. These options were available in previous versions.
- Stiffeners: Contains the two new options that force the program to always provide stiffeners in column-beam and ridge connections.
- Baseplate options
The same design options that are used in the Baseplates module are used for the baseplate design in the Joints I module, except for the type of anchorage of the bolt to the plate. These options are configured in the menu Baseplates > Options.
More information on the properties of the two Metal 3D baseplate design modules can be found in the Baseplates section.
Improvement in the joints analysis period
The time required for the joints design has been reduced with the use of multiprocessors (the user must have one of the two following modules: Parallel analysis with two processors or Parallel analysis with four processors).
Welded connection design in accordance to the ABNT NBR 8800:2008 (Brazil) code
Welded connection design has been updated for Brazil in accordance to the ABNT NBR 8800:2008 code (Projecto de estruturas de aço e de estruturas mistas de aço e concreto de edifícios).
- Metal 3D and CYPECAD’s Integrated 3D structures generate detailed ultimate limit state check reports of rolled and welded steel sections for the CTE DB SE-A (Spain) and CAN/CSA S16-01 (Canada) codes, and for cold formed steel sections for the NBR 14762 (Brazil) code.
These reports contain all the checks carried out by the program for the section design and therefore constitute an important document with which the user can:- Verify the design of the sections
- Optimise the design of the sections
The level of detail of these reports also provides an informative document, allowing the user to know all the checks to which the section has been submitted.
More information can be found on these documents in the detailed ultimate limit state check reports.
