**1. INTRODUCTION:**

FrameLoad is a post-processing program to obtain loads on frame sections.

In each section there is influence of several elements. Load extraction of a section is based on summation of forces in a specified point according to a coordinate system previously defined by the user. Origin of coordinate system is the same as the load summation point.

**2. INPUT FILES:**

Three main input files are needed by the program:

- Nastran results file – f06
- Topology model file – “cabecera”
- Section definition file – input.dat

**3. OUTPUT FILES:**

Two kind of output files are obtained from FrameLoad software:

- *.ren file (for each one f06 file). This file contains the Axial, Shear & Moment loads for all load cases in f06 file and sections.
- *.env file. This file contains the Axial, Shear & Moment load envelopes for all sections.

Ten critical load cases are selected by frame sizing from the complete set of load cases, according to the following criteria:

- Axial load (maximum and minimum)
- Shear load (maximum and minimum)
- Bending moment (maximum and minimum)
- Stress in free flange (maximum and minimum)
- R stress (combination of axial and shear stress)
- S load (combination of axial and shear stress)

**INTRODUCTION:**

BESTA (BEnding Stress Analysis) is a software tool to obtain the ultimate moment for metallic sections. It also calculates the Reserve Factor for sections subjected to axial and bending stress. This **free version** is limited to 6 points-section analysis

**Easy:**Easy and clear input data.**Fast**: Analysis is fast.**Formatted Output:**Results are obtained in a formatted output ready to be implemented in documents.

**INPUTS:**

Required input for BESTA are the geometry points defining the section, the material curve defined by points and the applied loads.

**OUTPUTS:**

Outputs obtained with BESTA are:

- Total section area
- Inertia moments around the principal axes parallel to X axis and Y axis
- X and Y coordinates of the Centre of gravity (c.o.g) of the section.
- Y coordinate of neutral fiber
- Ultimate Moment of the section.
- Bending Ultimate Strength ( FBu)
- Reserve Factor (RF) for the applied Moment and Axial load
- Strain and stress distribution along section height

ISM3007_CrossSectionProperties is a spreadsheet program that calculates the cross section properties. This spreadsheet is based in Sectprop spreadsheet developed by Yakpol.

**Easy:**There are different posibilities for geometry input**Visual:**Section geometry is graphically represented to be visually verified**Formatted Spreadsheet:**Results are shown in formatted tables so that can be directly used in documentation

Sections can be defined by three methods:

- By nodes
- By layers
- By segments (thin walled profiles)

Following section properties are provided by the program:

- Section properties about the axes parallel to the reference axes
- Area
- Centroid
- Inertias
- Section modulus

- Section properties about the principal axes
- Angle between the principal axe and the reference axe
- Inertias
- Section modulus

- Shear center (only for section defined by segments)
- Torsional constant (only for section defined by segments)
- Warping moment of inertia (only for section defined by segments)

**INTRODUCTION:**

This documentation presents the different ways to model the plasticity behavior in ductile metals and its implementation in the FEM ABAQUS Code.

All concepts are based in the engineering tension test, which is widely used to provide basic design information on the strength of materials and as an acceptance test for the specification of materials.

**Self-contained:**Documentation is self-contained so that there is no need to find extra information to understand the concepts**Application Tool**: An excel application tool is enclosed with the documentation to obtain directly Abaqus input data.**Examples:**Application examples can be found in documentation to apply concepts in a practical way

**CONTENTS:**

Contents included in documentation are the following:

- Material Strength paramenters
- Material modelling in Abaqus
- Defining material data in Abaqus environment
- DFEM modelling guidelines for non-linear analysis with Abaqus
- Post-processing of non-linear plasticity analysis
- Example of application

**INTRODUCTION:**

BOLT GROUP 3D is a software tool to calculate shear and tensile forces for each fastener in riveted or bolted joints. The method is valid only for components that are sufficiently stiff in the joint area. For the static strength analyses the centroid of the fastener group is determined taking into account the allowable forces of the fasteners

**Fast****:**Load per bolt is obtained immediately**Graphical Formatted Representation:**Graphics with bolt load distribution obtained as result are ready to include in documentation**Validation:**A load check is done as validation of input/output data

**INPUTS:**

Input data required for the analysis is:

**Properties of Riveting:**This information has to be filled for each type of rivet (or fastener) that appears in the Bolt Group distribution.**Name of the rivet**: internal name use in the Excel Sheet.**Allowables:**shear, tension rivet and tension nut allowables.

**Position, type and effectiveness:**complete one row for each rivet or fastener (50 rivets maximum):**Rivet number:**from 1 to the number of rivets.**Rivet Type:**same name as appears in 1.**Coordinates:**position of the rivet. The excel sheet supports only rivets that are located in the xy plane with z-coordinate = 0.0 and the z-axis as tension axis.**Effectiveness (Yes/No)**: user has to consider if the rivet admits shear and tension.

**Applied Loads:****Application Point:**position where the load is defined**Load:**force and moment components.

**OUTPUTS:**

When the parameters are filled, BOLT GROUP 3D tool automatically calculates loads per rivet, and graphical distribution of bolts and loads is shown when pressing button “Refresh Graphs”. A simple check can be done comparing Load Check cells with the Input Load to know if the results fulfil balance of forces and moments.
