STRUCTURAL FORM-FINDING FROM RECLAIMED BAR ELEMENTS

This thesis applies structural optimization techniques to develop a general methodology for design from reuse. A thorough case study serves as proof-of-concept. Reusing elements from dismantled structures appears as a promising, yet little explored approac ...

Evidence for structural damping in a high-stress silicon nitride nanobeam and its implications for quantum optomechanics

Tobias Kippenberg, Dalziel Joseph Wilson, Sergey Fedorov, Ryan Daniel Schilling, Vivishek Sudhir, Hendrik Schütz

We resolve the thermal motion of a high-stress silicon nitride nanobeam at frequencies far below its fundamental flexural resonance (3.4 MHz) using cavity-enhanced optical interferometry. Over two decades, the displacement spectrum is well-modeled by that ...

Combining finite element analyses and mechanical models for the assessment of reinforced concrete slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Raffaele Cantone

The influence of the level of deformation of the flexural reinforcement on the punching strength is well-established and mechanically founded since the pioneer works of Kinnunen and Nylander in the 1960’s. In code provisions, this influence is sometimes re ...

Long-term design of FRP-PUR web-core sandwich structures in building construction

Thomas Keller, Julia De Castro San Roman Fest, Sonia Yanes Armas

The structural behavior of GFRP-polyurethane (PUR) web-core sandwich structures subjected to sustained loading was investigated. As a basis, a study of the mechanical behavior of rigid PUR foams used as core materials was conducted, with emphasis on creep. ...

A Fluid–Structure Interaction Algorithm Using Radial Basis Function Interpolation Between Non-Conforming Interfaces

Alfio Quarteroni, Simone Deparis, Davide Forti

We consider a fluid–structure interaction (FSI) problem discretized by finite elements featuring two different grids that do not necessarily agree on the interface separating the computational domain of the fluid from the one of the structure. After identi ...

Funicular Explorations: Cardboard Box Curves Achieved through External Post-Tensioning

Corentin Jean Dominique Fivet, Catherine Elvire L. De Wolf

Structural designers often face the challenge of developing forms optimal for a broad range of requirements, but inefficient in terms of structural behavior. In these cases, bending moments often occur under normal loading, resulting in oversized, inelegan ...

Review of parameters influencing the structural response of a submerged body under cavitation conditions

Mohamed Farhat

Submerged structures that operate under extreme flows are prone to suffer large scale cavitation attached to their surfaces. Under such conditions the added mass effects differ from the expected ones in pure liquids. Moreover, the existence of small gaps b ...

Average spectral acceleration as an intensity measure for collapse risk assessment

Dimitrios Lignos

This paper investigates the performance of spectral acceleration averaged over a period range (Saavg) as an intensity measure (IM) for estimating the collapse risk of structures subjected to earthquake loading. The performance of Saavg is evaluated using t ...
