DOHA CONVENTION CENTRE AND TOWERTHE 10TH TALLEST BUILDING IN THE WORLD

APA ITU ‘HIGH RISE BUILDING’

International Conference on Fire Safety in High-RiseBuildings mengartikan bangunan tinggi sebagai “strukturapapun dimana tinggi dapat memiliki dampak besar terhadapevakuasi”.

New Shorter Oxford English Dictionary mengartikan bangunantinggi sebagai “bangunan yang memiliki banyak tingkat”.

Massachusetts General Laws mengartikan bangunan tinggilebih tinggi dari 70 kaki (21 m).

Banyak insinyus, inspektur, arsitek bangunan dan profesisejenisnya mengartikan bangunan tinggi sebagai bangunanyang memiliki tinggi setidaknya 75 kaki (23 m).

Bangunan yang lebih dari 492 kaki (150 m) disebut sebagaipencakar langit.

*The design of the new Doha Convention Center

and Tower by Murphy/Jahn architects creates an

iconic symbol for the Doha skyline – a 550m high

tapering obelisk, containing a total of 112 storeys.

It begins with offices in its lower levels, followed

by apartment floors, a hotel and penthouse

residences in the upper levels of the narrower

building shaft. At the top of the Tower an exclusive

Private Club occupies a 60m high glowing glass

cylinder, flanked by extensions of the obelisk

facades and supported by a soaring structural

helix. The shape of the Tower conforms to the

functional parameters of the design brief with a

subtle, elegant and dramatic form.

To the west lies the Convention Center. The

floating roof plane of metal and glass covers the

Exhibit Halls and extend out towards the Tower in

a broad sweeping arc. The strong horizontal

expression of the Convention Center compliments

the spectacular verticality of the Tower, yielding a

harmonious and unique building ensemble.

The Simsima Limestone is the main founding stratum in Doha,

Qatar. The weathering pattern of the Simsima Limestone iscomplex, with unweathered rock often overlying more weatheredrock, and the common presence of dissolution cavities secondarilyinfilled with uncemented material. To account for this variability, aweathering scheme has been developed that classifies the SimsimaLimestone in terms of rock quality, taking into account the relativepercentage of original limestone to secondary carbonate material;the degree of cementation of the secondary material; core recoveryparameters; and intact rock strength. The rock quality zones arethen related to engineering behaviour, especially as regards rockmass strength and stiffness. The classification of the SimsimaLimestone into rock quality grades has been utilized in a numberof recent geotechnical projects, where the improved classificationof this complex material has the potential to lead to savings interms of foundation design.
