Project:Steel structure Aircraft maintenance hangar facilities
Building type:aircraft maintenance hangar facilities
Construction area: 114421m2
Weight: 9513.09 metric ton
Structural steelwork description:
New airport aircraft maintenance hangar facilities is locaed in South Area of New airport,total construction area is 114421m2,construction area of steel structure building is 23100m2,total structural steelwork consumption is 9513.09 metric ton,it is one of the biggest aircraft maintenance hangar facilities for span and covered area during finished and undertaking hangar facilities.
No.11 steel hangar is the centre of whole hangar,the length in south-north direction is 409.04 meters,the width in east-west direction is 134 meters,the maximum span of steel structure is 100 meters + 150 meters + 100 meters,the depth is 102.91 meters,it could simultaneously allow 4 wide-body jets to maintain.
No.11 steel hangar is divided into 3 areas:area 1 and area 2 is maintenance area,area 3 is painting area.Structure is steel structure column plus steel roofing system.The steel roofing consists of multi-grades steel truss system in longitudinal and
lateral direction,and roof bracing system:
1. The main truss node adopts welded H steel nodes;
2. The primary member adopts hot rolled H steel,BS5950,50 Grade,British Standard;
3. The roof bracing system adopts hot-rolled square tube and circular tube , BS5950,50 Grade,British Standard.
The construction of steel roofing in maintenance area adopt special techniques:
installing into one part on the ground,hydraulic hoisting through computer control.
The main construction characteristics and difficulties:
1. Huge hoisting area:the total hoisting area covered is 250m×88m,it is the biggest single building,using integral hoisting techniques to hoist in one time currently in CHINA.
2. Big hoisting weight,big span:the weight reaches 4432t,clear span in the structure is 150m,they are both rare in the similar steel construction projects.
3. Much more Hoisting point-positions:totally 13 hoisting point-positions,32 lifting jacks,the maximum capacity of jacks is 360t.

4. Design ParametersIf you need we design for you, pls supply us the following parameter together with detail size:
1)Live load on roof(KN/M2)
3)Snow load (KG/M2) if have
4)Earthquake load if have
5)Crane (if have), Crane span, crane lift height, max lift capacity, max wheel pressure
Thermal transmittance criteria
The buildings are designed to fulfill the following thermal transmittance criteria:
|Building component||Maximum U-value (W/m2K)|
|Weighted average for all wall components||1.1|
The building is designed according to Eurocode,Icelandic National Annexes and the Icelandic Building Regulation.We have sent to the owner the load to foundations from the steel structures for each load case.
1. Permanent dead load:to be designed by us
2. Free dead load:Free dead load on the roof from installations is assumed=0.5KN/m2.
3. Crane load:the crane is 20mt crane,the load in crane specifications are characteristic loads.
4. Wind load: Vb,0= 36m/s,Terrain category = II For z=8.0 →Qp=1.80 KN/m2
External pressure coefficients is according to Eurocode
Internal pressure coefficients is assumed = -0.30/+0.20.
5. Snow load: s=1.26 x u Kn/m2,shape coefficient (u) is according to Eurocode.
6. Earthquake load:Design ground acceleration= 0.1g.
This steel building is classified as a C-building according to the Icelandic building Regulations.Maximum deflection for building in class C is as following:
|Total load||Variable load|
|Window frames||-||L/300 (max 8mm)|
