Novità della versione 2014.i
Improved code application. L and Z cold-formed sections for AISI/NASPEC-2007 (LRFD) (USA), AISI/NASPEC-2007 (LRFD) (Mexico) and CAN/CSA S136-07 (Canada)
- AISI/NASPEC-2007 (LRFD) (USA)
North American Specification for the Design of Cold-Formed Steel Structural Members. - AISI/NASPEC-2007 (LRFD) (México)
North American Specification for the Design of Cold-Formed Steel Structural Members. S136-07 Endorsed in Mexico by CANACERO. - CAN/CSA S136-07 (Canadá)
North American Specification for the Design of Cold-Formed Steel Structural Members. Approved in Canada by the Canadian Standards Association CSA.
These design standards were already implemented in CYPECAD and Metal 3D. As of the 2014.i version, the program implements the design of L and Z-shaped cold-formed sections.
Code implementation. NTDS. Norma Técnica para Diseño por Sismo (El Salvador)
Norma Técnica para Diseño por Sísmico (El Salvador)
Implemented in CYPECAD and Metal 3D.
The 2014.i version includes in CYPECAD:
- A static analysis method (equivalent lateral force)
The analysis method selection (dynamic or static) is carried out using the Analysis method option within the dialogue box where the seismic load is defined. - Correction due to base shear
This correction is applied to the seismic analysis using the dynamic analysis (spectral modal) method. To calculate the base shear with the ABNT NBR 15421:2006 code, CYPECAD offers two options for users to indicate the Fundamental period of the structure in two ways:
- Based on the code
- Specified by the user
More information on the correction due to base shear carried out by CYPECAD .
More information on how the fundamental period of the structure is determined .
Analyse the structure without obtaining the reinforcement
The 2014.i version includes a new analysis option: Analyse the structure without obtaining the reinforcement (Beam Definition tab > Analyse).
Using this option, users can obtain the forces and displacements of the structure without the need to design its elements. By not designing the elements, the time required to analyse the structure is reduced.
This can save users a substantial amount of time when structures requiring a long analysis period are being designed, since usually, the first analyses are used to check that the dimensions of the structural elements that have been introduced are adequate, so to avoid excessive displacements.
Implementation and update of ATEX (Brazil) removable form waffle slabs
New types of waffle slabs with removable forms, belonging to the Brazilian manufacturer ATEX, have been implemented. All floor slabs belonging to that manufacturer have also been updated. The 2014.i version has a total of 110 ATEX floor slabs available.
The previously mentioned implementation and update is available when one of the following Brazilian design codes has been selected:
- ABNT NBR 6118 Projeto Junho 2013
- ABNT NBR 6118:2007
- ABNT NBR 6118:2003
