Winding Reinforced UHPC Sandwich Structures for Lightweight Jackets for Offshore Megastructures

Implementing Self-upending for lightweight Jackets in Persian Gulf

Steel-structured jacket or template platforms have been extensively installed in Persian Gulf offshore oil & gas fields. For the jackets in the water depth range of 40 meters in this region, utilizing the self-upending concept has been investigated. It has been concluded that designing the light weight jackets, implementing the self-upending process for their installation operations, are econom...

Brillouin Corrosion Expansion Sensors for Steel Reinforced Concrete Structures Using a Fiber Optic Coil Winding Method

In this paper, a novel kind of method to monitor corrosion expansion of steel rebars in steel reinforced concrete structures named fiber optic coil winding method is proposed, discussed and tested. It is based on the fiber optical Brillouin sensing technique. Firstly, a strain calibration experiment is designed and conducted to obtain the strain coefficient of single mode fiber optics. Results ...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Composite Sandwich Panel Manufacturing Concepts for a Lightweight Vehicle Chassis

This paper presents an alternative concept for the production of a lightweight vehicle chassis, using preformed flat panels assembled into a primary structure by the simple processes of CNC routing, folding and adhesive bonding. Minimal tooling and a fully CAD integrated, software driven process provide considerable advantages in prototype development and series production: modifications can be...
