【正文】 onstructed is particularly severe, with chloride concentrations of up to %, and sulfates of up to %. The chloride and sulfate concentrations found in the groundwater are even higher than the concentrations in sea water. Accordingly, the primary consideration in designing the piles and raft foundation was durability. The concrete mix for the piles was a 60 MPa mix based on a triple blend with 25% fly ash, 7% silica fume, and a water to cement ratio of . The concrete was also designed as a fully self consolidating concrete, incorporating a viscosity modifying admixture with a slump flow of 675 +/ 75mm to limit the possibility of defects during construction. Due to the aggressive conditions present caused by the extremely corrosive ground water, a rigorous program of anticorrosion measures was required to ensure the durability of the foundations. Measures implemented included specialized waterproofing systems, increased concrete cover, the addition of corrosion inhibitors to the concrete mix. stringent crack control design criteria, and cathodic protection system utilizing titanium mesh (Figure 13) with an impressed current. Wind Engineering For a building of this height and slenderness, wind forces and the resulting motions in the upper levels bee dominant factors in the structural design. An extensive program of wind tunnel tests and other studies were undertaken under the direction of Dr. Peter Irwin of Rowan Williams Davies and Irwin Inc.39。這樣就可以使得建設(shè)不用碰到柱子運(yùn)輸過(guò)程中所碰到的種種問(wèn)題從而順利進(jìn)行。為了減少因?yàn)榛扑斐傻牟煌涌s短的影響，周邊的柱子的尺寸是這樣制定的：結(jié)構(gòu)自重在周邊柱子產(chǎn)生的壓力加上建筑在內(nèi)走廊的墻所產(chǎn)生的壓力。 （澳大利亞悉尼的結(jié)構(gòu)原理和動(dòng)態(tài)結(jié)構(gòu)資訊工程師顧問(wèn)）撰寫(xiě)了該地址的包含一次地震所可能帶來(lái)的災(zāi)難情況的地震預(yù)測(cè)分析報(bào)告。 .第三個(gè)階段：六個(gè)轉(zhuǎn)孔，兩個(gè)通過(guò)承載力測(cè)試，深度 達(dá)到 60 米。 風(fēng)荷載設(shè)計(jì) 對(duì)于這樣一座高而細(xì)長(zhǎng)的建筑，風(fēng)荷載和和風(fēng)荷載在高層的效應(yīng)成為了結(jié)構(gòu)設(shè)計(jì)的主導(dǎo)問(wèn)題。樁身的混凝土由 25%粉煤灰 7%石英粉和水灰比 的混凝土漿。摩擦樁是通過(guò)混凝土表面和巖石表面的聚結(jié)作用來(lái)實(shí)現(xiàn)承載的，而在底部樁體和巖土的摩擦力能夠達(dá)到 250 到 300kpa。 迪拜當(dāng)局政府制定迪拜為一個(gè)（美國(guó) 97抗震規(guī)范） 2a地震區(qū)（）。占少數(shù)比例的 C80 的混凝土在第 90天的初期彈性模數(shù)有 43,800 N/mm2。這個(gè)特點(diǎn)使得迪拜塔具有十足的抗水平荷載和抗扭剛度。 Phase I。 Structural Details of Burj Dubai The goal of the Burj Dubai Tower is not simply to be the world39。 La Grange multiplier methodology which results in a very efficient structure (Baker et ah, 2020). The reinforced concrete structure was designed in accordance with the requirements of ACI 31802 Building Code Requirements for Structural Concrete The wall thicknesses and column sizes were finetuned to reduce the effects of creep and shrinkage on the individual elements which pose the structure. To reduce the effects of differential column shortening, due to creep, between the perimeter columns and interior walls, the perimeter columns were sized such that the selfweight gravity stress on the perimeter columns matched the stress on the interior corridor walls. The five (5) sets of outriggers, distributed up the building, tie all the vertical load carrying elements together, further ensuring uniform gravity stresses: hence, reducing differential
