 Introduction

This section contains a series of Strand7 tutorials, captured and displayed in Lotus Screen Cam format. The tutorials consist of complete Strand7 sessions showing how the models are built, solved and results extracted. Each tutorial is broken up into short stages. These should generally be viewed in stage order, but if you want to see a specific stage again, just select it by clicking the appropriate picture.

 

 

The tutorials are narrated so you will require a sound card on your computer to get the most benefit from them. The video will still run without a sound card.

 

 

If you are using Internet Explorer:

When you select and click on a tutorial, a window appears with the message You have chosen to download a file from this location ...., What would you like to do with this file?
Select "Run this program from its current location".

A security warning may appear (depending on your internet settings). If the warning Are you sure that you want to install and run ???.exe appears, select YES to continue.

 Building

Multi-storey building

This tutorial demonstrates the use of the linear static and natural frequency
solvers for the analysis of a multi-storey building. Use is made of the Group
tree to simplify both the model construction and the post-processing.

Stage 1 creates the first floor.

 

 

Stage 2 assigns groups and
properties and creates the
other floors.

 

 

Stage 3 adds the loads and
restraints then solves the
linear static problem.

 

 

Stage 4 creates the combination
 cases and post-processes the
linear static results.

 

 

Stage 5 solves the natural
frequency problem and
post-processes the results.

 

 

 

 

 

 

 Shed

Shed support structure

This tutorial exemplifies the use of beam elements in Strand7 for the construction
of frame-like structures. Multiple load cases and load case combinations are
illustrated, together with the extraction of results on beam elements, such as
moment diagrams.

Stage 1 creates the first frame of
the shed.

 

 

Stage 2 completes the shed
support structure.

 

 

Stage 3 creates the cladding,
applies the loads and restraints
and solves the model.

 

 

Stage 4 post-processes the
results.

 

 

 

 

  

 

Drop test

Steel frame drop test

This tutorial demonstrates the use of the nonlinear transient dynamic solver
in Strand7, for modelling a steel frame being dropped onto a set of springs
and dampers. The solver considers the contact nonlinearity of the impact.

Stage 1 creates the basic frame
from beam elements.

 

 

Stage 2 defines contact elements,
springs and restraints, then solves.

 

 

Stage 3 post-processes the results.

 

 

  

 

 

 

 Welded lug

Stress in weld of welded lug

This tutorial demonstrates the construction of brick meshes in Strand7, via
the analysis of stresses in the weld of a welded lug.

Stage 1 starts with a plate mesh
and creates a solid 3D brick mesh.

Stage 2 applies the restraints and
loads.

Stage 3 solves and post-processes
the results.

 

  

 Concrete curing

Curing of concrete

This tutorial demonstrates the use of the heat solver in Strand7 by modelling the
curing of concrete. The coupling of the thermal results to the structural solution is
also demonstrated.

Stage 1 creates the basic mesh.

 

 

Stage 2 defines the thermal
boundary
conditions, properties and solves.

 

 

Stage 3 post-processes the heat
transfer results and prepares the
model for a structural solution.

 

 

 

 

 

 

 

Intersecting pipes

Intersecting two cylindrical pipes

This tutorial demonstrates some of the tools available in Strand7 for intersecting
surfaces made from plate/shell elements. Two cylindrical pipes are intersected.

Stage 1 constructs the surface of
the inclined pipe and prepares for
the fillet at the intersection.

 

 

Stage 2 constructs one quarter
of the main pipe.
