# STRUCTURAL ANALYSIS 2 - 2021/2

Module code: ENG3176

## Module Overview

The module provides an introduction to modelling complex structural behaviours used in practice for the design and analysis of structures. The Finite Element Method is introduced as a general tool for the numerical simulation of complex structural behaviours. Various topics associated with nonlinear structural behaviours, such as second-order effect, plastic collapse, and structural instability, are introduced.

## Module content

Finite element method – an introduction to the method, including modelling principles, truss structures, frames structures and plate/shell structures. Introduction to the use of verification and validation processes in structural analysis modelling;

Nonlinear structural behaviours concerning structural failure:

• Plastic collapse – kinematic approaches to estimation of plastic collapse loads for beams, simple frames and simple slabs;

• Stability – an overview of structural stability theory and its significance;

• Second order effect – or termed as P-delta effect, considering the effects of imperfection and/or deflection on the load-deflection analysis.

As a core subject within Structures, this module will mainly cover the threads of 1) Design; and 2) Health and Safety Risk Management, and also contribute to the thread Sustainability.

## Module aims

• Introduce different analytical and numerical approaches to assess the performance of different structural elements (i.e. frames, trusses, slabs and columns) commonly found in structural engineering.
• Provide an appreciation of relevant topics in structural engineering such as second order effect for load-deflection analysis, plastic collapse, and instability which can govern the design/analysis of structures.

## Methods of Teaching / Learning

22 hours of lectures, 11 hours of tutorial classes, 30 hours of coursework and 87 hours independent learning.

2 hours examination.

Total student learning time 150 hours.

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
