2. APA ITU ‘HIGH RISE BUILDING’
 International Conference on Fire Safety in High-Rise
Buildings mengartikan bangunan tinggi sebagai “struktur
apapun dimana tinggi dapat memiliki dampak besar terhadap
evakuasi”.
 New Shorter Oxford English Dictionary mengartikan bangunan
tinggi sebagai “bangunan yang memiliki banyak tingkat”.
 Massachusetts General Laws mengartikan bangunan tinggi
lebih tinggi dari 70 kaki (21 m).
 Banyak insinyus, inspektur, arsitek bangunan dan profesi
sejenisnya mengartikan bangunan tinggi sebagai bangunan
yang memiliki tinggi setidaknya 75 kaki (23 m).
 Bangunan yang lebih dari 492 kaki (150 m) disebut sebagai
pencakar langit.

7. Dilihat dari konsep design yang menggunakan RAM konsep
model struktur. Bahwasanya bangunan ini menggunakan
struktur beton bertulang dengan inti pusat dan empat mega-kolom
di sudut. Post-dikencangkan lembaran dengan tendon
terikat dan rincian disesuaikan untuk melompat-bentuk
teknologi konstruksi inti pusat (core). (tipe system struktur

10. OVER VIEW
SBMAs (Southern Building

yang dapat dipindahkan
dipasang untuk
mendukung dinding
beton bertulang
diafragma. Penggunaan
teknologi jangkar dilepas
adalah wajib di wilayah
tersebut. PROYEK
Seperti banyak negara di Tengah-Timur,
Qatar mengalami Pertumbuhan
ekonomi yang luar biasa tercermin
dalam dengan cepat memperluas
infrastruktur. The Doha Convention
Centre dan Menara Proyek terdiri dari
beberapa 105 No.lantai dan khas dari
jenis konstruksi yang ada dalam terus
berubah skyline. Itu penggunaan
dinding diaphrgam untuk mendukung
struktur bawah tanah adalah umum
dan stabilitas dinding tersebut seringkali
bergantung pada jangkar tanah.

11. KONDISI TANAH
Penggalian dilakukan
dilemah kapur (disebut
sebagai 'Simsima Limestone')
yang ditandai dengan rekah
berat dan adanya rongga.
SOLUSI
Dalam upaya untuk
memenuhi lingkungan dan
fisik kendala dikenakan pada
proyek itu diusulkan bahwa
711 No 600kn bekerja jangkar
beban dilepas digunakan
untuk memberikan dukungan

memiliki perimeter total
sekitar 1300m dan sampai
tiga lantai mendalam.
KONSTRUKSI
SBMA, bekerja sama dengan Ammico,
mengawasi sidang program jangkar
ditujukan untuk membangun in-situ
obligasi stres nilai dan menunjukkan
penghapusan efektif pada tendon dari
lubang bor. SBMA juga dibantu dengan
pembentukan depot fabrikasi tendon
pada situs dan menyarankan pada
semua aspek pembangunan,

16. *
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.

19. Simsima Limestone

 The Simsima Limestone is the main founding stratum in Doha,
Qatar. The weathering pattern of the Simsima Limestone is
complex, with unweathered rock often overlying more weathered
rock, and the common presence of dissolution cavities secondarily
infilled with uncemented material. To account for this variability, a
weathering scheme has been developed that classifies the Simsima
Limestone in terms of rock quality, taking into account the relative
percentage of original limestone to secondary carbonate material;
the degree of cementation of the secondary material; core recovery
parameters; and intact rock strength. The rock quality zones are
then related to engineering behaviour, especially as regards rock
mass strength and stiffness. The classification of the Simsima
Limestone into rock quality grades has been utilized in a number
of recent geotechnical projects, where the improved classification
of this complex material has the potential to lead to savings in
terms of foundation design.
