Advancing Circular Economy in the existing building stock: A methodology to support building characterisation for sustainable refurbishment design
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The lack of standard practices and platforms for assessing refurbishment strategies towards Circular Economy (CE) and their impact in global warming constitutes a challenge for the decarbonization of existing building ... -
An experimental study of reinforced concrete beamcolumn joint with partially high strengthened longitudinal bar
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)It is necessary to generate the yield position away from the column face to minimize damage to the beam-column joint during a large earthquake in a reinforced concrete building. The same efficacy can be realized using ... -
Analyses of the geometrical properties of fine recycled aggregates
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The acquisition of natural sand and dumping of fine recycled aggregates (FRA) are two serious environmental problems that can be solved simultaneously by using FRA as replacement of natural sand in high-end applications. ... -
Analytical simulation on experimental seismic response of headed anchors embedded in reinforced concrete
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)This paper deal with a series of dynamic response analyses, carried out to give numerical correlation of hysteretic behavior of cast-in-place anchorages obtained by the static loading and shake table tests. Specimens for ... -
Analyzing the impact of the aspect ratio of a building on concrete use in its structure
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Buildings consume over half of annual energy supply as embodied and operating energy in their construction and operation releasing harmful emissions to the atmosphere. Over 90 % of the embodied energy is attributed to ... -
Application of high performance concrete for reconstruction
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)One of the sustainability aspects of the construction is a sufficient durability. In objectively justified cases, the durability is enhanced by reconstruction. To ensure economic design of the reconstruction, non-liner ... -
Applying life cycle assessment with minimal information to support early-stage material selection
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Traditional life cycle assessment (LCA) is too data intensive and time consuming to be used during typical building design processes. Conducting an LCA during the building design process therefore requires simplifications ... -
Artificial intelligence - finite element method - hybrids for efficient nonlinear analysis of concrete structures
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Realistic structural analyses and optimisations using the non-linear finite element method are possible today yet suffer from being very time-consuming, particularly in case of reinforced concrete plates and shells. Hence ... -
Assessment of existing structures under climate change
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Assessment of the influence of human activities on recent, current, and future global and regional climate conditions and extremes has advanced sufficiently to provide a reasonable measure of its impact across the globe. ... -
ASSESSMENT OF SHEAR STRENGTH PARAMETERS OF SOIL FROM LOAD MICROPILE TESTS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Design and evaluation of the bearing capacity of micropiles are based on shear strength parameters of the soil within which a micropile is installed. These parameters are mostly received from laboratory tests or as an ... -
Attitude towards LCA in Hungary and Czechia – Results of a survey among building design professionals
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Architects and designers have a critical role in promoting Life Cycle Assessment (LCA), a scientific methodology for evaluating the environmental impacts of buildings that can help decarbonise the built environment and ... -
Augmented reality to support parcel handling in last-mile logistics
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)We have developed an augmented reality (AR) based system which keeps track of events during the parcel handling process for last-mile logistics. The system can retrieve and highlight the location of parcels in large piles ... -
Automatic extraction of 3d building meshes from LiDAR data
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Terrestrial laser scanning and drone-based scanning are often combined to gain a complete picture of the external envelopes of buildings. While the resulting data sets are easy to understand for humans, extracting any ... -
Axial behaviour of strengthened circular hollow reinforced concrete column with CFRP partial confinement
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Circular hollow reinforced concrete column will experience deterioration due to many causes such as natural disaster, corrosion, low quality and others. Therefore, structural strengthening is required since replacing the ... -
Behavior of predried mature concrete beams subject to partial wetting and drying cycles
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The presented research focuses on the behavior of predried concrete beams with 2.5 m span subjected to cycles of nonsymmetric wetting and drying. Wetting is induced by partially immersing the specimens in a water basin. ... -
Benchmark VERCORS 2022: mechanical response of the prestressed concrete containment wall to ambient conditions
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The VERCORS benchmark was developed to provide a solid experimental basis for numerical modeling of concrete containment buildings (CCBs) to extend their lifespan. The goal of the first phase of the third benchmark is to ... -
Bending behavior of adhesively-bonded engineered wood-concrete composite decks
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Four-point bending tests were conducted on five medium-sized (i.e., 2300 mm in length and 215 mm in width) engineered timber (laminated veneer lumber (LVL) and cross-laminated timber (CLT)) - concrete (wood chip concrete ... -
Benefits of pervious concrete for urbanized habitats
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Pervious (draining) concrete is a new generation concrete which, for its structure, allows rainwater to enter the subsoil and at the same time is determining the final surface without the need for any additional layer. ... -
