Dimensions and effective mechanical steel areas of slabs for capacity checks of concrete columns and beams

CYPECAD, as of previous versions, takes into account the capacity design criteria of concrete beams and columns, for specific codes when undertaking the seismic analysis of the structure . The geometric and mechanical properties of the columns and beams are automatically contemplated with the capacity checks (as of previous versions) as are, optionally, the properties of […]

Fundamental period of the structure with user values for NSR10 (Columbia) and NC 46:1999 (Cuba)

When either of these codes is used in CYPECAD (NSR-10 (Columbia) and NC 46:1999 (Cuba)), there are two options to indicate the value of the Fundamental period of the structure (used to calculate the base shear): Both options can be selected in the Estimation of the fundamental period of the structure section in the Code for the calculation of seismic loading dialogue […]

Reinforcement ductility criteria and capacity design criteria for seismic design for the combination of Eurocode 2 concrete code (EU, France and Portugal) and Eurocode 8 seismic code (EU, France, Portugal and Belgium)

The 2014.d version of CYPECAD includes the reinforcement ductility criteria and the capacity design criteria when they are combined in the same analysis with the Eurocode 2 concrete codes: Eurocode 2 (EU), Eurocode 2 (France), Eurocode 2 (Portugal) with their corresponding seismic codes. More information on the combined use of these concrete and seismic design […]

Seismic analysis. Ductility reinforcement criteria and capacity design criteria for seismic design of concrete columns and beams with the NEC-11 (Ecuador) code.

The seismic code of Ecuador, NEC-11 (Norma Ecuatoriana de la Construcción. Capítulo 2.- Peligro sísmico y requisites de diseño) was already implemented in CYPECAD and Metal 3D as of previous versions. As of the 2013.n version, if users select the NEC – 11 seismic code of Ecuador and combine it with the ACI 318M-08 (USA) concrete code, CYPECAD’s Advanced beam editor and column editor may also be […]

Seismic analysis. Seismic design criteria for concrete beams and columns with the NBDS-2006 (Bolivia) and Norma Técnica E.030 (Peru) codes

More information on the seismic design criteria for concrete columns and beams applied by CYPECAD with these two design codes can be found in the section on Improvements in code application (Concrete code and Loads on structures. Seismic loads) on this webpage.

Seismic analysis. Automatic calculation of the number of vibration modes

A new section has been implemented within the dialogue box where the selected seismic code parameters are defined (Job > General data > Select With seismic loading > Choose a seismic code): Number of vibration modes considered in the analysis. Here, the program offers different ways to establish the number of vibration modes to be considered […]
