CALCULATION OF SEISMICALLY LOADED EARTH RETAINING STRUCTURES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Eurocode 1998-5 for the design of earth retaining structures in seismic conditions describes calculations using the Mononobe-Okabe method. This simplified quasi-static procedure is to some extent very conservative. The ... -
Calibration of a summer building simulation model based on monitoring of user behaviour
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Occupant behaviour is a field, that has always been of great interest to researchers. It could significantly modify the operation of the building and the user’s energy needs, and it is also difficult to model it according ... -
Catalogue of construction products containing secondary raw materials from different industries and municipal waste
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The building industry consumes a large amount of primary raw materials and also contributes significantly to the production of waste. Applying circular principles in this field to reduce resource consumption and waste ... -
Characteristics of business models for innovation clusters in decarbonation projects
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Roughly 97 % of the European Union (EU)’s building stock is not considered energy efficient, and 75 to 85 % of it will still be in use in 2050. Residential buildings account for around two thirds of final energy consumption ... -
Chloride ion penetration behaviour in concrete containing an expansive additive and a calcium-aluminate-based additive
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The effect of the material characteristics on the infiltration behaviour of chloride ions in concrete containing a combination of an expansive additive and a calcium-aluminate-based additive has been investigated. The same ... -
Circular concrete: validating new technologies in the lab and on-site
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The growing importance of a circular economy also holds possibilities for concrete. Some of the principles of circularity, like the re-use of "waste" as secondary raw material and the optimisation of the design with regards ... -
Circular design in the Global South
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)One Planet Sustainable Buildings and Construction Programme (SBC), led by the Ministry of the Environment, Finland and co-led by RMIT University and UN Environment Programme was initiated in 2015. Work on circular built ... -
Circular design strategies through Additive manufacturing: MoDom, a “circular building” housing model
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The doubling of the global use of raw materials in the last century is an established environmental emergency due to an all too common “take – make – dispose” linear development model. Strategic plans within the Green Deal, ... -
Climate-resilient and resource-conserving architecture through renewable building materials and microclimate improvement
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Due to climate change, together with the need to reduce the ecological footprint and the future resource shortages, a climate-resilient and resource-conserving architecture must be reinforced. Dealing with the issue of ... -
Closing the loop of textile: Circular building renovation with novel recycled insulations from wasted clothes
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The implementation of new energy policies and standards for NZEB is expected to lead to a significant reduction of GHG emissions from building use in Europe in the next decades. On the other side, the growing pressure on ... -
Comparative flexural performance of steel fibre reinforced self-compacting concrete (SCFRC) ribbed slab with different fibre provision area
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The flexural performance of three SCFRC ribbed slabs with different fibre provision area were investigated in this paper; in both ribs and flange (SFWS), ribs only with additional welded mesh in flange (SFT) and in ribs ... -
Comparing the environmental performances of new and renovated school buildings
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Evaluating which is the best choice between renovating an existing construction or building a new structure in countries like Italy, where a huge post-war un-listed building heritage does not satisfy the current standards ... -
Comparison between concrete stress diagrams according to the Brazilian standard ABNT NBR 6118: 2014
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)This study aims to compare methods for the determination of concrete properties by means of the stress diagrams present in the Brazilian standard ABNT NBR 6118: 2014. The area under the stress diagram, the internal reactions, ... -
Comparison of FETI-based domain decomposition methods for topology optimization problems
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)We critically assess the performance of several variants of dual and dual-primal domain decomposition strategies in problems with fixed subdomain partitioning and high heterogeneity in stiffness coefficients typically ... -
Comparison of selected parameters for evaluation of rail surface damage intensity
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)This paper deals with the issue of evaluation of a rail surface damage (RSD) intensity. Some ways of calculating parameters that represent the RSD are described. In this context, a multi-body model of a railway vehicle was ... -
Comparison of the collapse frequency and failure probability of buildings
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)In a previous study, the collapse frequencies and associated mortalities of buildings were compiled based on various publications.
