Objectives

- To move from the elementary design of structural steel members to the concept of steel design of structures and buildings and study their failure modes due to lateral loads and vertical progressive collapse;
- To provide technical knowledge relevant to the design of details in steel structures, such as moment connections and base-plates;
- To introduce the different types of prestressed concrete elements and the main technological aspects relevant to their production and design;
- To provide the technical knowledge required to design beams and other structural elements with prestressed concrete using EC2;
- To introduce structural forms of masonry (walls and columns) and to provide technical knowledge on masonry design construction and details;
- To introduce timber as a structural material and provide technical knowledge on timber design as well as its applications in structural engineering including connections;
- To provide more complete means for the design and analysis of steel, concrete, masonry and timber structures and to familiarise students with a range of typical processing techniques;
- To provide practical guidance on the use of relevant standards, namely EC2 (concrete), EC3 (steel), EC5 (timber), and EC6 (masonry).

Learning outcomes
On completion of the module students will:

1. be able to apply their prior knowledge and understanding of the scientific and mathematical principles of engineering to design steel, concrete, masonry and timber structures;
2. have an appreciation of the fundamental design philosophies adopted in the area of design of structures and buildings;
3. be able to apply mathematical and computer-based models for solving problems in engineering and be able to assess the limitations of each particular case;
4. be aware of the latest research and developing technologies related to the design of steel, concrete, masonry and timber structures.


Students completing this module will have gained the knowledge, understanding, skills or abilities that contribute to achieving the following ARB General Criteria for Part 1:
• understand the constructional and structural systems, the environmental strategies and the regulatory requirements that apply to the design and construction of a comprehensive design project; GC1.2
• develop a conceptual and critical approach to architectural design that integrates and satisfies the aesthetic aspects of a building and the technical requirements of its construction and the needs of the user; GC1.3
• the investigation, critical appraisal and selection of alternative structural, constructional and material systems relevant to architectural design; GC8.1
• strategies for building construction, and ability to integrate knowledge of structural principles and construction techniques;GC8.2
• the physical properties and characteristics of building materials, components and systems, and the environmental impact of specification choices; GC8.3


Syllabus

In this module students gain an understanding of the more advanced aspects of structural steel building frame behaviour such as progressive collapse (and avoiding disproportionate collapse); the sway stability of braced and unbraced multi-storey building frames; the design of multi-storey frames with rigid connections and the consideration of fabrication details, connections and health and safety risk management during construction as an integral part of the building design process. This builds on previous steel design teaching and provides the students with the underpinning knowledge required to inform the design of multi-storey buildings.

The students are also given an introduction to the different forms of prestressed concrete (pre- and post-tensioned); partially prestressed concrete and the use of bonded or un-bonded tendons in construction. This provides the students with the knowledge needed to specify and evaluate different types of floor construction (and also the use of long span concrete construction in buildings with column/wall free zones).

Students also gain an understanding of masonry and timber construction including the specification of alternative forms of masonry and different species of timber and forms of timber construction (including glulam construction and the use of cross laminated timber). Masonry detailing (movement joints and the strapping and tying of roofs and floors) and the connections to create stabilising diaphragm floor action in timber buildings (including timber framed buildings) are also covered in the teaching.
