Name of building location : Airbus Industrial Hall in Toulouse, France

Year of completion: The 2011-2014 phased delivery of the halls

Contract value: The total building cost was €68m euro excluding tools.

Long-span structure system adopted: The wing-lifting cranes roll on rails suspended on the truss of theframe of the roof.sliding doors provide a 117 x 32 m² opening.

They are supported by their own structural frame. This huge

structure was designed and installed economically using fabricated

sections and a trussed upper beam.

Building use: Steel construction provides efficient long span and low weight structural frame

for large industrial halls that will produce the next generation A380 Airbus

aeroplane for intercontinental flights.

Key dimension and size including max:This industrial building covers 200,000 m of floor space, is 45 m high and²provides spans of more than 115 m.Criteria to be met were efficient space

occupancy and flexibility in arrangement of the internal space.

Due to the expected change in the industrial process after several years of

production, a reconfiguration/refurbishing approach design was considered,

taking count of rapid financial return. Architectural and structural appearance

were intended to be an attractive reflection of the company performance.

The largest hall, which is 115 m long by 250 m wide, is equipped

with the following heavy cranes:

Two parallel industrial rolling cranes,50 m span, 22 tonnes

capacity for lifting of the wings.

Two parallel industrial rolling cranes, 35 m span, 30 tonnes

capacity for fuselage transportation. Two dual loads 2 x 4

suspended cranes for normal service.

Span roof covering/finishing adopted the roofs are designed:

Construction Details Roof and roof trusses

The roof trusses span 117 m. The height of the trusses varies from 8

m at the supports up to 13.5 m at mid span. The main roof elements

are composed of two parallel truss frames of 33 m span along the

building and made of rectangular hollow steel sections.

Each roof element comprises a pair of front and rear trusses, roof

structure, roof service equipments, fire safety network, etc., and

when completed at ground level is lifted and positioned at the top

of the columns in one piece. Columns are rigidly fixed to the ground

and have equal slenderness ratio in each direction to avoid any

horizontal buckling phenomenon during lifting operations.

Assembly of the trusses at ground level has the advantage of

achieving safe construction, limited use of scaffolding, a simple

operation and fast construction process. The joints between the

truss elements and the top of the columns are pinned.

This simple method provides the following advantages:

Rapid connection operations in a critical erection phase.

No welding operation during assembly.

The truss upper flange element is connected and simply sits on

a short span beam on top of the column.

The vertical deflection of the trusses was limited to span/2000 due

to crane operation requirements.

The elements of the main truss spanning across the building were I

shape fabricated sections and bolted on joints. Each column was made

of two separate fabricated sections jointed by a continuous truss

web.

There are have several types of application Benefits:

Fast track construction

Efficient use of steel components

Flexibility of space organisation

Sustainable design approach

High crane facilities

Name of building location : Air Cargo hub at East MidlandsAirport, UK

Year of completion: There Opening airport to passenger since april 1965

and started from 1993 has extension to there opened for cargo, and started 2000

there running the cargo facilities.

Contract value: The total building cost was 45 million Euros. Opened a new £35m cargo facility on site.

Building use:

DHL has operated at Nottingham East Midlands Airport in the UK for

25 years. With business volume increasing, the existing ‘hub’ was

unable to cope and a new major facility was designed, capable of

handling shipping volumes of over 1,000 tonnes per year. The 40,000

m2 facility comprises two distinct parts: a warehouse distribution

area and office area, for this office area has provides 9,000 m2 of

additional space for 650 staff and also is 3 storeys high.

Long-span structure system adopted and key dimension and size including max :

A new distribution warehouse and office has been built for DHL at

Nottingham’s East Midlands Airport. The warehouse is constructed

from a double bay steel portal frame that is adopted with spans of

40 m and the offices use 18 m span cellular beams. The distribution

area uses a structural grid that was dictated by the modular

mechanical handling system and allowed for future expansion. The

mechanical handling system was placed on a mezzanine level which was

constructed after the building envelope had been completed

Span roof covering/finishing adopted the roofs are designed: Based on the span of floor area, the predicted lifespan in its

current format was only 15 years. Because of those, Cellular beams

is a chosen to provide services integration through the 600 mm

diameter openings. The design of the office area was further

complicated by the need to span over a service road, which

necessitated supporting the floors from a long span truss of roof

level. The open sided canopy was also problematical, being 22.5 m

span and 45m wide between supports. The canopy projected at 45O and

was connected to the portal frame structure for its stability. The

roof of the office comprised curved steel beams of 150 m radius.

There are have several types of application Benefits:

Simple portal frame solution provides efficient use of space

Mezzanine floor using cellular beams supports handling equipment

3 storey office uses 18 m span cellular beams

18 aircraft stands provided 30 truck bays below a 22.5 m span canopy
