WHY THIS KIND OF STRUCTURES SYSTEM USED ?

DESIGN CONCEPT

The provision of semi public space gives the user a casualexperience in the rural area. The changes in spatial experiencefrom a narrow to widen space could catch people intention andSensation toward nature.

This diagram show you the difference in a typical MTR stationand this sunny bay station.

The arch form has the benefit of the environmental andthe spatial advance

Down-stand Raft FoundationRAFT FOUNDATION

A raft foundation is a continuous foundation in two directions,usually covering an area equal to or greater than the base are-a of the structure which it carries.

There’s 3 kinds of raft foundation : plain slab raft,slab and beam raft,cellular raft

But why down-stand beam and slab raft foundation ?It is suitable for lightly loaded structures on low bea-ring capacity ground. Compare to up-stand one, it re-quires much less excavation.

RAFT FOUNDATION

The structures are pure tensile fabric surfaces havinga curvature at a given point and in a particulardirection, which is of the opposite sign to thecurvature at that point in a perpendicular direction

Sunny bay station is arched vault structure, it achieves:Light self-weightEasy seismic treatmentLong span 3-dimnesional curvy formPre-casting elements

MATERIAL

Light weight & thin (0.5-1.5 kg/m²)Highly tension resistSoftHigh fire ratingDurable (over 25 years)Translucent (7~25 % diffuse light)Reduce heat load (block 65-75% heat transfer)Self-cleaning (low friction, can be cleaned by rainwater)

Make use of the green surrounding but block exceeding sunlight

CONSTRUCTION PROCESS

WIND LOAD

Easy Form (form making)

Easy San (force-density & loading analysis)

Easy Cut (membrane cutting & distortion analysis)

COMPUTER SIMULATION

Computer simulation software: “ EASY ” , ’’IMAGES’’, ‘’Forten 32’’, ‘’inTENS’’, ‘’Fabdes’’Almost all of them includes 3 procedures. Take ‘’Easy’’ as example:

HOW DO THE DETAILS WORK WITH THE DESIGN ?

GLAZING

The steel structure allow the maximum lighting,The drying fixing system allow for bettermaintenance and allows tolerance and movementfor the train.

Joint

The pin joints only rotates in 2 axis plate

JOINT

The movable plate of the pin joint above the footing is not aligned to any axis plate to prevent collapse

The pin joint can be used to build up spanningmembers into grid structure, such as trusses andgirders, which become a framework of struts andties, making large, relatively light, spanning framesfor longer spans.It allows rotation, do not transfer bending, whilefixed or rigid joint do redistribute bending stress intothe support.It avoids deformation of structure after shocking. Inthe case of Sunny Bay Station, it allows themovement along one direction.

This is a Pin-Fuse Joint. It slips and rotates undercritical seismic forces, allowing a steel structure toroll with the movement of the

HOW DOES THE DESIGN HELP ENVIRONMENTAL FRIENDLY ?

VENTILATION

Building FormIts curvature was calculated to optimize air movement

Semi-Open SpacePanoramic from the platform

Natural Ventilation with Water mist cooling systemThe water mist cooling system not only produce mist for instant cooling effect for the visitors,but helps cooling the bottom. On the other hand, the top of the envelope is heat up by the sunlight.As a result, air pressure difference increase within the envelope and achieve better natural ventilation.
