Within the frame of the research project “An integrated static-dynamic structural optimization approach for the design of footbridges”, the Structural Mechanics Section of the Department of Civil Engineering and the Architectural Engineering research group of the Department of Architecture have a vacancy for one PhD student. We are looking for a PhD student with a MSc degree in civil or architectural engineering and an excellent background in structural mechanics. The PhD student will be hosted in both research groups which have their own focus, yet sufficient overlap for successful collaboration. Research in the Structural Mechanics Section (https: // www. kuleuven.be/bwm) of the Department of Civil Engineering focuses on the static and dynamic analysis of structures and is structured along six research lines: vibrations in the built environment, vibration based structural identification and evaluation, building acoustics, shape and topology optimization, computational structural engineering and human-induced vibration of civil engineering structures. Research in the Structural Optimization research group of the Architectural Engineering Section of the Department of Architecture focuses on gradient-based size, shape, and topology optimization of structures (https: // architectuur.kuleuven.be/structopt). The Departments of Architecture and Civil Engineering are nicely located in and around the Arenberg Castle on Campus Arenberg of KU Leuven in Heverlee, one kilometre from Leuven's city center.
This project aims at the development of an integrated structural optimization approach for footbridges that simultaneously considers static and dynamic loads. In current practice, footbridges are generally designed based on static loading considerations only. Since these static loads are relatively low, they can be made very slender, which makes them susceptible to human induced vibration. For this reason, a verification of the vibration levels is needed once the static design has been elaborated. When the levels are too high, the problem is mostly solved by adding tuned mass dampers (TMDs). Although the original design of the structure is largely preserved, some modifications are needed to accommodate these units, while their tuning also requires a testing of the footbridge after it has been built. The primary objective of this project is to develop an integrated design optimization methodology that incorporates static as well as dynamic design criteria. For small or moderate spans, such a procedure should allow determining a design which simultaneously satisfies the static and dynamic design requirements, avoiding ad hoc modifications after the static design. In order to achieve this goal, we will build on recent developments in structural optimization, remediate shortcomings in current analysis procedures for human induced vibrations, and take into account the recent trend where composite materials are become increasingly popular for footbridge design.
The research will be carried out by two PhD students who are expected to closely collaborate. The first PhD student PhD1 will focus on the development of the integrated design methodology for steel footbridges. The second PhD student PhD2, will focus on the development of the integrated design methodology for composite footbridges, including the planned experiments. The present vacancy is for PhD student PhD1, PhD student PhD2 is recruited at Ghent University, partner in this research project.Profile
