In this project you will focus on structural form finding of compression-dominated structural systems for buildings. The structural system will be composed of discrete blocks made up of 3D printed concrete. Compression-dominant behavior will be achieved by designing an optimized structural form that directs forces primarily into compression paths, minimizing tensile stresses. This behavior will be further enhanced through mechanically induced compression using iron-based shape memory alloy (Fe-SMA) reinforcement. You will perform the following tasks: Topology optimization of discrete blocks to ensure material-efficient design Investigation of the mechanical strength characteristics of discrete blocks with small-scale experiments Development of innovative joining techniques for discrete blocks, with a focus on potential for deconstruction Large-scale experimental testing of compression dominant structural systems under quasi-static loading Your profile

In the framework of MSCA Doctoral Network (DN) Consumer Energy Demand Flexibility in Electricity Use (CoDEF) project, we are looking for a motivated and experienced PhD candidate to perform consumer flexibility aware planning of multi-energy districts. A particular focus lies on the modelling and optimization of multi-energy consumer flexibility to estimate its contribution on system sizing, demand reduction and security of supply. Challenges encompass - among others -, multi-energy system design and integration. Historical data in the Empa's NEST demonstrator and its multi-energy back-bone will be utilized to design multi-energy districts. The candidate shall translate his/her research ideas to tackle these challenges, in close collaboration with our inter-disciplinary team and external scientific and industry partners. The candidate will support our master students, publish in scientific journals, and participate in conferences. The PhD candidate will be enrolled at KU Leuven (Prof. Erik Delarue). A secondment of 6 months at KU Leuven and 3 months at Urban Sympheny AG is planned during the third year of the PhD. Your profile

This PhD position is offered as part of an SNSF-funded project investigating low-damage 3D printed concrete walls reinforced with iron-based shape memory alloys (Fe-SMAs). The PhD project aims to develop a nonlinear finite element modeling framework to simulate the mechanical bond behavior between 3D printed concrete and cast concrete. To inform the model, small-scale experimental investigations - including direct shear, slant shear, and direct tension tests - will be conducted to characterize the bond. A particular focus will be on understanding how differential stiffness between the two concretes and interface waviness influence bond behavior. Building on the insights at small-scale level, the research will extend to the structural scale, examining the composite action between 3D printed concrete and cast concrete infill under axial compression. This will be achieved through a combination of finite element modeling and experimental testing of composite wall panels under axial compression. The planned tasks for PhD are as follows: Formulation of a numerical modeling framework to model interlayer and interfacial bond behavior Modeling of interlayer and interfacial bond behavior at the local-level using prism specimens Modeling of composite action at the global level of a wall panel Experimental investigation of the mechanical bond behavior of the hardened interface between 3D printed concrete and cast concrete Experimental investigation of composite action of 3D printed concrete and cast concrete under axial compression in 3DPC wall panels Analytical modeling of the composite action of 3DPC and cast concrete under axial compression in 3DPC wall panels Your profile and selection criteria
