Norma Brasiliana ABNT NBR 6118 (2014). Projeto de estruturas de concreto - Procedimento.
La presente norma brasiliana sul calcestruzzo, la cui entrata in vigore ha avuto luogo il 29 maggio 2014, è stata implementata in CYPECAD e in altri programmi del software CYPE nella versione 2015.a.
Norma Brasiliana ABNT NBR 6118 (2014). Projeto de estruturas de concreto – Procedimento.
Implementata in CYPECAD, CYPE 3D (Strutture 3D), Verifica a punzonamento, Elementi di fondazione e Travi continue.
This code was already implemented in CYPE programs as of previous versions.
Now, with the 2014.m version, when Eurocode 2 (Rumania) is selected in CYPECAD, columns and beams are edited using their corresponding advanced editors.

If a seismic analysis is carried out, Eurocode 2 (Rumania) is compatible with a group of seismic codes which allow for the advanced beam and column editors to continue to be used, and take into account the capacity design criteria for concrete columns and beams:
The 2014.j version includes two options to define the end of each column span in a different manner when exporting the CYPECAD job to IFC (Industry Foundation Classes) format:
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:
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.
Norma Técnica para Diseño por Sísmico (El Salvador)
Implemented in CYPECAD and Metal 3D.
The 2014.i version includes in CYPECAD:
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 .
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.
Projeto de estruturas resistentes a sismos - Procedimento.
This code was already implemented as of previous versions for CYPECAD and Metal 3D for the dynamic analysis method (modal spectral).
The 2014.h version includes in CYPECAD:
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.
When CYPECAD carries out a dynamic analysis (modal spectral) to calculate the seismic action, users have the option to not consider any floors below ground level in the dynamic model. To do so, the option “Consider the floors below ground level in the dynamic model” has to be deactivated.
On the other hand, when designing in accordance to some seismic standards, the minimum base shear condition must be met when a dynamic analysis (modal spectral) is applied. This minimum value is equal to a percentage of the shear at the base of the structure (base shear), which is calculated using a static method.
As of the 2014.g version, the calculation of the base shear takes into account the deactivating of the “Consider the floors below ground level in the dynamic model” option. In other words, if users deactivate this option, the program only takes into account the floors above ground level when calculating the base shear using the static method.
