Duhamel Integral | DegreeTutors.com

Simulating crowd vibrations using the Duhamel Integral

In this Python mini-project, you’ll learn about the Duhamel Integral and how it can be used to simulate the dynamic response of a single degree of freedom system. We’ll discuss how to solve the integral and then write some Python code to implement our solution for any arbitrary loading. In the second half of this project, we’re going to use our Duhamel Integral solver to build a crowd loading simulation. This will allow us to simulate the vibration response of a footbridge to pedestrian traffic.

Beam Deflection Calculator_cover | DegreeTutors.com

Building a Beam Deflection Calculator in Python

In this project, we’ll build a beam deflection calculator that can generate beam deflections by directly integrating the bending moment diagram. The technique we’ll use for calculating deflection in this project is not limited to statically determinate structures, although you will need a complete bending moment diagram to integrate. This project builds on our previous Shear Force and Bending Moment Calculator project. So at the end of this project, the final result will be a complete beam analysis code that calculates beam reactions, shear forces, bending moments and deflections.

Building a Shear Force and Bending Moment Diagram Calculator in Python

In this project we’re going to build a Shear Force and Bending Moment Diagram calculator using Python in the Jupyter Notebook development environment. Generating the shear force and bending moment diagram for a simple beam with anything other than basic loading can be a tedious and time-consuming process. Once you finish this project, you’ll have a calculator that can produce shear force and bending moment diagrams at the push of a button.

YOUR TUTOR

Hi, I’m Seán, the founder and lead tutor at DegreeTutors.com. Before turning all my attention to DegreeTutors, I spent 10 years teaching students about engineering analysis and design at the University of Exeter, Warwick University and The University of Nottingham. I’m a Chartered Engineer and Fellow of the Higher Education Academy.

DegreeTutors is designed to support students and construction industry professionals to enhance their engineering analysis and design skills. Whether you want to sharpen up on the basics of constructing shear and moment diagrams or want to better understand how to analyse complex, indeterminate structures (with or without a computer), by taking courses with me on DegreeTutors, you’ll build the knowledge and skills you need.

If you’re interested in leveraging the power of Python programming to supercharge your analysis and design, then this is also the place for you…whether you’re brand new to programming or already proficient.

After completing this course you’ll have developed a complete workflow for the modelling and analysis of non-linear 3D cablenet structures.

In this course, we’ll expand beyond what we covered in our study of 2D non-linear cables by adapting the tools we built previously, for the analysis of non-linear 3D cablenet structures.

However, instead of just modifying our existing code, we’ll spend time fleshing out a complete workflow that takes you from initial form-finding of cablenet geometry, right through to iterative stiffness method simulation to identify the cablenet deflections and tension profile.

If you’re intrigued by these elegant and efficient structures and want to understand how to analyse their behaviour, this course is for you. Keep in mind that the tools developed in this course are not meant to be a replacement for commercial non-linear solvers. Our objective is to build your understanding of the behaviour of cablenet structures and geometric non-linearity more generally. The best way to do this is to roll up your sleeves and build your own solver.

After taking this course, you’ll be able to use commercial software which much greater confidence now that you understand what’s happening behind the scenes. The code developed within each section of the course is also provided for download as a reference.

This course is divided into 8 sections:

  • Introduction, Course Breakdown & Prerequisites
  • Developing the 3D non-linear stiffness matrix
  • Extending our Blender Utility Scripts
  • Extending our solver toolbox from 2D to 3D
  • Cable-stayed antenna tower…in 3D
  • Parametric modelling and form-finding in Blender
  • Cablenet Pavilion – Hyperbolic Paraboloid
  • Frei Otto’s Dancing Fountain in Cablenet form

The final code will be capable of handling structures like the one pictured above that consist of a mixture of axially loaded cable (tension only) and bar (tension and compression) elements. Our solver implements an iterative algorithm, so a solution that converges is not always guaranteed! We’ll be leaving the relative comfort and certainty of linear analysis behind!

This course picks up where Non-linear finite element analysis of 2D catenary & cable structures using Python. Make sure to cover that course first, before starting this course.

After completing this course, you’ll have built an iterative numerical solver for cable and truss structures that exhibit geometric non-linearity due to large deformations.

Next

This course focuses on building the understanding and tooling necessary to analyse structures that undergo large deformations when loaded. These large changes to the geometry of a structure can alter the internal stress distribution within the structure. This is known as geometric non-linearity and requires a more sophisticated solution strategy.

This course will build on the understanding developed in previous DegreeTutors courses and in particular our linear 2D analysis course, The Direct Stiffness Method for Truss Analysis with Python. It is strongly recommended that you complete this course first before tackling non-linear analysis.

We’ll place particular emphasis on cable and catenary structures as these are classic examples of structures whose deformation under load can lead to geometric non-linearity. However, the code developed can be equally deployed to flexible truss structures.

The tools developed in this course are not meant as a replacement for commercial non-linear solvers (we’re not going to be rebuilding SAP2000! :) – the objective here is to build your understanding of the behaviour and the best way to do this is by implementing what you learn by building your own solver.

This course is divided into 9 sections:

  • Introduction and course overview
  • ‘Heavy’ cables – the linear solution
  • Getting comfortable with non-linearity
  • The non-linear stiffness matrix
  • Building our 2D solver toolbox
  • Visualising the results
  • ‘Heavy’ cables – the non-linear solution
  • Modelling initial geometry in Blender
  • Mixing cables and bars in the same model

The final code will be capable of handling structures like the one pictured above that consist of a mixture of axially loaded cable (tension only) and bar (tension and compression) elements. Our solver implements an iterative algorithm, so a solution that converges is not always guaranteed! We’ll be leaving the relative comfort and certainty of linear analysis behind!

You DO NOT need to be a Python programming guru to take this course. If you’ve taken the prerequisite course – or even if you’re just familiar with basic programming ideas like functions, loops and variables that will be plenty to get you started. 👍

This course is for anyone who wants to understand multi-degree of freedom (MDoF) structural dynamics. The course is built around the theme of seismic analysis and determining the response of structures to earthquake-induced ground motion.

In reality, that’s just one form of excitation; when you complete the course you’ll be able to handle ground motion as well as any kind of directly applied dynamic loads such as wind loading or blast pressure waves for example.

This course is divided into 6 sections:

  • Welcome and preliminaries
  • Introduction to ground motion modelling
  • Modelling Multi-DoF Dynamic Systems
  • Modal Analysis and Decoupling the Equations of Motion
  • Damping Orthogonality
  • Bringing it all together: N-storey response to earthquake ground motion

The course culminates in you developing a code for analysing the response of multi-story structures to realistic ground motion. The final code will be capable of handling anything from a 2 to 200 storey shear building. More important than the code itself, is the fact that you’ll understand how and why every line of it works – meaning you’ll have no problem adapting it or further developing or customising it for your own use beyond this course.

You DO NOT need to be a Python programming guru to take this course. If you’ve taken any of the prerequisite courses – or even if you’re just familiar with basic programming ideas like functions, loops and variables that will be plenty to get you started. 👍
