Seismic Regions

<p>The paper provides an overview of the technologies and connections proposed and tested for accelerated bridge construction (ABC) in seismic regions from New Zealand and the United States in the last seven years. These solutions can be divided in terms of emulative and non‐emulative cast‐in‐place connections. Emulative cast‐in‐place connections aim to achieve a similar seismic performance to that of conventional cast‐in‐place construction during an earthquake. A variety of emulative connections have been tested in New Zealand and in the United States, with some being implemented in actual bridges. These connections include grouted ducts, member socket, pocket, splice‐sleeve, and other connections. Similarly, various non‐emulative connection were tested using large‐scale specimens. These include dissipative controlled rocking, hybrid sliding‐rocking, shape‐memory alloys, and pre‐tensioned rocking. From these, only the dissipative controlled rocking and shape‐memory alloys, have been recently implemented in construction of actual bridges in seismic regions in New Zealand and in the United States, respectively. The paper discusses the aspects associated with emulative and non‐emulative connections.</p>

Mission Profile

This article will present a morphing wing actuated using both surface embedded Shape memory alloys (SMAs) and trailing edge Macro-fiber composites (MFCs). This combination enables the airfoil to simultaneously achieve large scale deformations at low frequencies as well as rapid actuation with a limited amount of displacement. Thereby not only can the shape of the airfoil be optimized in function of the current mission profile but also the shear layer can be influenced. Each actuator is modelled using both a finite element and/or an analytical model and the results will be verified experimentally.
