César BartoloméIngeciber S.A.


Material Library

• Advanced concrete modeling– Simplified and accurate creep modeling

• Step by step method • Effective modulus method

– American Code ACI 209R-92– EHE – CEB -90 CODE– EUROCODE 2

Non-LinearMaterials

• Construction process through material definition: Material birth and death


Steel and Concrete Sections

User friendly definitionfor any shape

Local buckling of slender beams

Automatic definitionof section shape

Automatic definition of preliminary reinforcement


Concrete Checking and Design

• Codes– EUROCODE 2– ACI 318 – EHE, CTE (Spanish)– CEB-FIP (Model Code)– British Standard 8110– Australian code (AS 3600)– Chinese code (GB-50010/ GB-

50017)– Brazilian Code NBR6118– Indian Standard 456– Russian SP 52/1001/2004

Load Combinations

• Where must be located the two engines to obtain the maximum stresses at point P ?

• What is the maximum bending moment at section A-A ?• What are the concomitant values?

PA ---- A

? ?

With the combination explorer, you can be sure

of covering all the possibilities


Capturing Solid Sections

Automatic generationof cross section

ANSYS 3D model

It allows checking & design of beam cross

sections captured from a 3D solid model


Standardized Structures

Truss Catalog


Concrete Shell Bending Design

An icon shows the

reinforcement location


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)


Bridge Sections

• It’s possible to define holes• The sections can be symmetric or asymmetric• Sections and the hole diameters might differ along the bridge• Any generic box section can be easily defined


Loads Generation (Traffic Loads)

Vehicle library: just choose the vehicle and the corresponding properties are automatically

defined

Property window

• With the vehicle editor it is possible to create, import from library, modify, copy, delete and list vehicles


Soil Structure Interaction

• Direct Foundation

• Deep Foundation

• Retaining wall


Wizard for Tunnels design


Slope Stability

• With just one calculation, it’s possible to visualize the resultsaccording to the different available methods.


Seepage Analysis

• Calculating hydraulic heads and pore water pressures• Obtaining the saturation line for 2D problems


Summary

• CivilFEM allows civil and safety code validations for a wide range of constructions across North and South Americas, Europe, Asia and Australia

• It addresses needs for civil constructions, steel constructions, nuclear power plants for wide variety of load conditions including seismic analysis

• Some niche capabilities include easy analysis of prestressed reinforced concrete, soil structure interaction, tunnel design, slope stability analysis, seepage analysis and many more
