INTRODUCTION
The purpose of this steel design coursework is to reinforce your understanding and application of design knowledge gained during your masters degree. This is individual coursework and counts 33% towards of the module. There are a total of seven design assignments within the project, detailed as follows:

D1 Design philosophy/Analysis of load data and calculation of design loads [10 marks]
D2 Analysis of portal frame [15 marks]
D3 Structural Design of Portal Frame (rafters and columns) [15 marks]
D4 Design of 10m span secondary composite beam [15 marks]
D5 Design of typical Column-Rafter Haunched Connection [15 marks]
D6 Design of stability system for building [15 marks]
D7 Sketches and drawings [15 marks]
TOTAL [100 marks]

Detailed, but limited, information and data are given in this handout. You are expected to produce standard design calculations to the current Eurocodes as set out below and quality sketches of selected structural details.

· BS EN 1990-1 – Basis of Structural Design
· BS EN 1991-1-1 – Actions on Structures – General actions- Densities, self-weight, imposed loads for buildings.
· BS EN 1991-1-3 – Actions on Structures – General actions – Snow loads
· BS EN 1991-1-4–Actions on Structures–General actions–Wind actions
· BS EN 1991-3 – Actions on Structures – Actions induced by cranes and machinery.
· BS EN 1993-1 – Design of Steel Structures – General rules and rules for buildings
· BS EN 1993-6 – Design of Steel Structures – Crane supporting structures.

Calculations must be done on standard University of Leeds A4 calculation sheets. Alternatively, calculations may be typed up in Word or other suitable word processing software. Drawings and sketches should be done neatly using pencil, or CAD, on plain (with title block) A4 or A3 size paper.

 

DESIGN SPECIFICATION
2.1 Scope

Design of long span roof members, typical columns and their connection to the rafter, a typical 10m composite floor beam, the principle elements of the bracing system and sufficient sketch details/drawings to communicate the structural intent of the scheme to the reader.
 

2.2 Building Requirements
The design covers the main structural elements of a new light industrial building in Humberside. Outline details of the proposed scheme are given in
the accompanying drawing:
? Sheet - 001 - Column Plan
? Sheet - 002 - Mezz Plan
? Sheet - 003 - Roof Plan
? Sheet - 004 – Sections/Elevation
? Sheet - 005 – 3D
The drawings detail the dimensional requirements of the structure.

Other design criteria are as follows:

(a) Steel members – Grade S355
(b) Floors ? 150mm o/all composite, formed with Corus Comflor 47, 0.9mm gauge profiled steel decking
(c) Ceilings – to ground floor area only: 0.15kN/m 2
(d) Services – to office area: 0.15kN/m 2
(e) Services – to 30m span roof: 0.15kN/m 2
(f) Cladding:
Roof: Kingspan KS1000 ZIP Insulated Panels (SW: 0.15kN/m 2 )
Walls: Kingspan KS1000 ZIP Insulated Panels (SW: 0.15kN/m 2 )
You may assume these roof/wall panels can span up to 2.2m between supports
(g) Fire protection: Steel frame – sprayed on coating
(h) The analysis of the structure may be carried using appropriate engineering software. However the output from any analysis must be fully validated. Any computer generated analysis will not be accepted unless accompanied by sufficient hand verifications.

 

DETAILS OF DESIGN ASSIGNMENTS
D1 ? Analysis of load data and calculation of design loads
Analyse the general design data provided to calculate the following:
The design load at both SLS and ULS for all the applied variable and permanent actions applied to the roof and office floors.
· Design philosophy/basis of design.
· The net wind loads to each elevation, and the roof, of the structure.

Your attention is drawn to the relevance of Clause 5.1.1 (BS EN 1993?1) on the method of design, and the use of appropriate load factors in accordance with BS EN 1990?1 (EC0) and EN1991?3.

D2 – Analysis of portal frame
Structural analysis of one typical internal frame for all relevant load conditions. In undertaking this analysis assume the connections between the mezzanine floor and all columns are pinned – i.e. the portal frame rafter and columns provide stability to the building in the east-west direction with the mezzanine floor providing no assistance to this.

D3 – Structural Design of Portal Frame (rafters and columns)
Structural design of rafter and columns to one typical internal frame. In undertaking these checks you must consider all relevant load combinations. For restraint positions to rafter/column compression flanges you are expected to determine these yourself based on the data in this brief.

D4 – 10m span composite beam
Design a typical 10m span composite beam to support the ultimate and service loads computed in D1.

D5 – Column-Rafter Haunched Connection
Design of typical Column-Rafter Haunched Connection to support the ultimate loads computed in D1.

D6 – Typical set of horizontal and vertical bracing in roof and walls
Design sufficient horizontal roof bracing and vertical wall bracing to justify that stability of the structure is satisfied. In relation to the configuration of this bracing you are to determine this yourself.

D7 – Sketches and drawings
Provide sufficient annotated drawings & sketches to clearly communicate your design intent.
