Seismic Analysis

• Utilities to make easier the seismic spectral analysis: – Spectrum definition according to codes (Spanish, Eurocode

8,Italian, Chinese GB50011,UBC, and others under request)

– Automatic mode combinations according to code specifications(SRSS, CQC)

– CFRAPPN seismic sign utility

Seismic Analysis

• Non Linear Time History Analysis • Push-Over and Retrofit Analysis• From the spectrum definition, it is possible to perform a

Push-Over calculation which allows: • Analyze the evolutive behaviour of the structure• Determine its weak points.• Analyze the Retrofit effect.

Prestressed Reinforced Concrete 3D Tendon Editor

• It allows the definition and edition of the geometric and strength properties of all tendons of a structure. The geometry may be shown and edited either graphically or by coordinates

• Graphical visualization of all prestressing losses for each tendon along the structure (short and long term losses)
