A novel shape optimization approach for strained gridshells: Design and construction of a simply supported gridshell

AbstractIn this paper we consider the inverse problem of simultaneously reconstructing the interface where the jump of the conductivity occurs and the Robin parameter for a transmission problem with piecewise constant conductivity and Robin-type transmission conditions on the interface. We propose a reconstruction method based on a shape optimization approach and compare the results obtained using two different types of shape functionals. The reformulation of the shape optimization problem as a suitable saddle point problem allows us to obtain the optimality conditions by using differentiability properties of the min-sup combined with a function space parameterization technique. The reconstruction is then performed by means of an iterative algorithm based on a conjugate shape gradient method combined with a level set approach. To conclude we give and discuss several numerical examples.

Design And Construction

<p>This paper presents the Ain Sukhna Product Hub, a marine terminal facility recently finished in the Red Sea, Egypt, including the design and construction of a 3 km long offshore roadway. Formed by 83 simply supported spans, the roadway structures are elements that can greatly impact on the construction planning. An overview of the fast track nature of design, procurement and construction of this significant offshore structure are presented, describing the main design works and construction methods and highlighting the importance of the coordination with construction team and reality of the specific conditions in the project’s country.</p>
