Update history​​

CYPECAD

Improvements have been implemented in the following seismic codes:

  • NC 46:1999 (Cuba)

Construcciones sismo resistentes. Requisitos básicos para el diseño y construcción.

  • NSR-10 (Columbia)

Reglamento Colombiano de Construcción Sismo Resistente (2010).

These codes were already implemented in CYPECAD and Metal 3D, as of previous versions. They are used in CYPECAD together with the ACI 318M-08 (USA-International) code.

As of the 2013.j version, if users select the ACI 318M-08 (USA International) code and combine it with either of the previously mentioned seismic codes, they can then use CYPECAD’s advanced beam editor.
If the NSR-10 (Colombia) code is combined with the NSR-10 concrete code (Colombia – Título C – Concreto estructural), users can also use CYPECAD’s advanced beam editor.

Construcciones sismo resistentes. Requisitos básicos para el diseño y construcción.

This code was already implemented in CYPECAD and Metal 3D as of previous versions. It is used in CYPECAD together with the ACI 318M-08 (USA – International) concrete code.

As of the 2013.j version, if users select the ACI 318M-08 (USA International) code and combine it with this seismic code, they can then use CYPECAD’s advanced column editor.

Norma Boliviana de Diseño Sísmico (2006). Título A. Análisis y diseño sismo resistente.

Implemented in CYPECAD and Metal 3D.

More information on the implementation of capacity design criteria for the seismic design of concrete columns and beams can be found in the Capacity design criteria for seismic design of concrete columns and beams with the NSR-10 (Colombia) code section of the new features of CYPECAD on this webpage.

Reglamento Colombiano de Construcción Sismo Resistente NSR-10. Título C ‑ Concreto estructural.

Implemented in CYPECADMetal 3DStairsFoundation elements, and Continuous beams.

CYPECAD's advanced column and beam editors are also available with this code.

A new module: Post-tensioned concrete slabs for buildings has been included in the 2013.j version of CYPECAD, which has been created to design the passive reinforcement of post-tensioned slabs before calculating the forces of the post-tensioned tendons (bonded or unbonded) and whose properties have been introduced by program users.

Post-tensioned technology has different degrees of acceptance in many countries. CYPE has designed this module given the increasing demand of CYPECAD users to have a tool which can design post-tensioned concrete slabs.

The Post-tensioned concrete slabs for buildings module allows users to introduce the path of the tendons, their definition, the post-tensioned forces and percentage loss. The program generates a post-tensioned loadcase in which the deviation loads produced by the path of the tendons are introduced. During the slab reinforcement design stage, and if the tendons have been defined as bonded, if there is any capacity excess or shortage regarding the contribution of the active reinforcement, it will be taken into account to establish the passive reinforcement. 

More information on this new CYPECAD module is available here: Post-tensioned concrete slabs for buildings

When exporting to IFC format (Industry Foundation Classes) from CYPECAD (File > Export > IFC), users could select, as of previous versions, amongst four options (IFC 2x3, Archicad IFC 2x3, Revit IFC 2x3, Allplan IFC 2x3). Now, in the 2013.i version, the option for Revit Architecture is split into a further two options: Revit 2012 IFC 2x3 and Revit 2013 IFC 2x3. This way, CYPECAD contemplates the IFC format variations for these two Revit Architecture program versions.

This improvement is also contemplated when exporting to IFC from CYPECAD MEP.

The design of the anchorage of longitudinal reinforcement has been improved for jobs that can use CYPECAD’s new beam editor (depends on the selected design code).

A new button, Edit the frame’s reinforcement, has been added in the Beam errors dialogue box (Results tab > Beams/Walls > Select beam), for jobs that can use CYPECAD’s new beam editor, which allows users to access the beam editor directly and view the frame, displayed centred on the span selected previously by the user (in the Beam errors dialogue box).

This way, users can quickly view the information offered by the beam editor without having to select the span displaying error warnings, using another option of the program.

CYPECAD designs the longitudinal reinforcement of beams without limiting the number of reinforcement layers contained in the various horizontal planes, for the jobs that can use CYPECAD’s new beam editor (depends on the selected design code).

CYPECAD’s new beam editor (Results tab > Beams/Walls > Edit beams) was implemented in the 2013.e version, and since then more concrete design codes have been added to those available. Now, for the 2013.i version update patch, the ACI 318M-08 (USA) code has been implemented.

The concrete codes available for CYPECAD’s beam editor are:

  • ABNT NBR 6118:2007 (Brasil)
  • EHE-08 (España)
  • IS 456: 2000 (India)
  • ACI 318M-08 (USA)

More concrete codes will implemented in upcoming update patches of the 2013 version.

The 2013.e, 2013.g and 2013.h versions of CYPECAD implemented the capacity design criteria for bending and shear for the seismic design of concrete supports, and capacity design criteria for shear for the seismic design of concrete beams in accordance with the following codes: EHE-08 (Spain), NCSE-02 (Spain) and IS 13920:1993 (India).

Now, implemented for the 2013.i version, is the capacity design criteria for bending and shear for the seismic design of concrete supports, and capacity design criteria for shear for the seismic design of concrete beams in accordance with the ACI 318M-08 code.

The capacity design criteria which are currently implemented are:

  • For concrete supports:
  • Capacity design criteria for bending and shear in accordance with Annex 10 of the EHE-08 code (Spain).
  • Capacity design criteria for bending in accordance with NCSE-02 code (Spain)
  • Capacity design criteria for shear in accordance with IS 13920: 1993 (India)
  • Capacity design criteria for bending and shear in accordance with ACI 318M-08 (USA)
  • For concrete beams:
  • Capacity design criteria for shear in accordance with Annex 10 of the EHE-08 code (Spain).
  • Capacity design criteria for shear in accordance with NCSE-02 (Spain).
  • Capacity design criteria for shear in accordance with IS 13920: 1993 (India).
  • Capacity design criteria for shear in accordance with ACI 318M-08 (USA).

These design criteria are applied in CYPECAD and are specified in the Detailed Ultimate Limit State check reports if the selected codes are those which have been indicated.
