Core Connection

Central Core Service Transmits Gravity Loads

Since the Burj Al Arab is built on a man-made island into the sea, certain geotechnical considerations had to be considered. Mainly, the ground beneath the Burj Al Arab is sand and silt. To take this into account, the foundation was made with cement piles that reach a depth of 130 feet. The foundation of this superstructure does not reach bedrock; therefore the stability comes from the shear forces along each deep pile.

  The Burj Al Arab withstands gravity loads through the

stability of the two intertwined V’s of steel and concrete. The concrete walls and slabs come out from the point of the V which is a special service core. At the end of each floor level are wings. Gravity loads are transferred down from the core and wings to the foundation. The use of a core and wings was suitable for this structure to allow for the world’s largest atrium to be enclosed between the two sides of hotel suites.

3 Tube Steel Trusses

Cross-bracing and Curved Truss Arch

Teflon Coated Fiberglass Fabric

As a tall building, the lateral loads of the Burj Al Arab are of most importance. Due to the geographic location in the Persian Gulf, winds and seismic activity had to be considered. The building was built to withstand a fifty year wind of 100 miles per hour and a seismic ground acceleration of 0.2 times gravity (Reina).

  The structure transfers lateral loads in a number of ways.

First, the Burj Al Arab has three tubular steel trusses on the outside of the two sides of the V. These trusses act as cross bracing to wind and earthquake forces. The translucent fabric wall of the atrium is not only a stunning architectural feature but also helps transfer lateral load. The fabric covers a series of steel cross bracing and is comprised of two layers of fiberglass material which is Teflon-coated. The fabric goes over the trussed arches mentioned before. Due to the rigidity, lateral loads are transferred to the fabric wall which acts similar to a diaphragm. The shape of Burj Al Arab lowers wind forces more effectively then a square building because of the streamlined V and curved fabric atrium wall.

One new technology that was used was Cantilever’s Top Climbing Jump Form system for the main core area. Cantilever Pty Ltd, Queensland, Australia designed and furnished the 300 ton forming system. A top climbing jump form system requires the form to hang off a structural steel grid and to be jumped utilizing a dozen synchronous electric - operated screw jacks that lift the entire system by pushing off the top of the walls previously poured. The form system chosen for the wing walls and the stair cores was Doka's SKE automatic-climbing form system. The wing areas of the building house the two-storey suites. Each of the six walls per wing are 13 meters long and were poured in 3.57 meter lifts. Doka designed the forms such that only two climbing brackets per form were necessary. The fewer suspension points meant fewer man hours were required for each operation therefore saving time and money.

Another place where technology was used was in the form system for the main floors. This form system was also designed, manufactured and furnished by Cantilever Pty Ltd. This form was designed as a flying cable and was supported by brackets attached to the walls. The form itself weighed 18 tons. The frame for each form was constructed with large castellated steel beams and measured 18.3 meters long by 8.1 meters wide. Once the slab was cast and reached sufficient strength, the forms were jacked down off the wall brackets and flown into the next position with tower cranes. The table forms saved time by eliminating the need for shoring labor to hold them up. In addition, Meinhardt International helped the joint venture re-engineer the slabs to a post-tensioned design, reducing the labor on reinforcing steel and time required to get sufficient strength to strip the form (Doka).

The forming a joint venture the companies undoubtedly contributed the most to the success of the project. The companies’ use of value engineering, constructability, and preplanning and planning that included all members of the group helped to keep cost down as well as keep up with the schedule that was set by the owner.
