The Technology Agency of the Czech Republic is an organizational unit of the state that was founded in 2009 by the Act No. 130/2002 Coll. on the support of research, experimental development and innovation. The creation of TA CR is one of the cornerstones of the fundamental reforms in research and development (R&D) in the Czech Republic. The key features of the reform is the redistribution of financial support from the national budget. The Technology Agency of the Czech Republic simplifies the state support of applied research and experimental development which has been fragmented and implemented by many bodies before the reform.

Project TJ02000140 Implementation of load transfer function for optimization of deep foundation of buildings
Period: 2019 – 2021
Program: Zéta
Provider: Technology Agency of the Czech Republic
Project participants: Institute of geotechnics, Faculty of Civil Engineering, Brno University of Technology, GEOSTAR spol. s r.o.
Introduction of the project
Software for design and verification of axially loaded deep foundation utilizing the load-transfer method. It is possible to perform an analysis of large-diameter bored piles and micropiles for which an equivalent young modulus is caclulated based on selected reinforcement. Two types of nonlinear load transfer functions (hyperbolic and cubic-root) are involved. The effectve stress approach (beta method) is applied in order to determine the ultimate skin friction profile along a pile. According to the chosen level of aanalysis, it is possible to to consider the constant/depth-dependent beta values and an additional radial stress increase due to the constrained dilatancy effect. The resulst of analysis are: the load-displacement curve and the axial stress, axial displacements and mobilized shaft friction profiles along an anlyzed foundation. It is poddible to export the analysis output into the pdf file.

Introduction of the project
Our society’s move towards near-zero energy buildings (NZEB) requires the application of renewable heat and cold sources that will be economically efficient enough to gain ground in practice. This potential has a system of using the heat and cold of the ground for heating and cooling buildings through thermally activated foundation piles – the so-called energopilot. By equipping the foundation piles with pipelines with a liquid circuit, it allows, at low costs, to use an advantageous and relatively constant soil temperature over time and, in combination with a heat pump, to achieve high heating and cooling factors compared to other energy sources. Energy yield and economic efficiency for the given basic conditions must be designed and assessed individually in relation to the type of building and the way it is operated. For this purpose, it is necessary to create a numerical model of heat transfer in the energy piles and the surrounding soil, connect it to the model of the building and their energy systems, and apply appropriate optimization methods. The promotion of energopiles in the Czech Republic is limited, among other things, by the concerns of structural engineers, because the thermal activation of energopiles affects the construction-mechanical function of the foundation piles, especially their thermal expansion, which negatively affects casing friction and can thus reduce their load-bearing capacity and usability. In order to assess this effect, it is necessary to carry out computer simulations and experimental measurements of mechanically and thermally loaded piles, and to process the obtained results into a design software that will be an aid to experts in building statics.
