Parametric optimization of steel shell towers of high-power wind turbines
(Procedia Engineering, 2013)This paper presents a parametric optimization task of steel conic shell towers of wind-powered generators. The minimum weight of the steel tower has been considered as purpose function when produced capacity of the ... -
Overview of risk allocation between construction parties
(Procedia Engineering, 2013)Certain risks are inherent in all construction projects. These risks are faced by all parties involved in a project – owners, contractors, designers, suppliers, etc. However, the more important role the parties play in ... -
Flexible approach in infrastructure design buffer parking case study
(Procedia Engineering, 2013)The purpose of this article is to present the problem of flexible designing in the construction industry. When designing building structures, one must take into account the mutual interrelations between various systems ... -
Competence model for the architectural engineering professional
(Procedia Engineering, 2013)Motivation. Modern design practice, where an architect works with engineers in a large team, lacks optimization. If collaboration between the professions of architecture (A.) and engineering (E.) were improved, it would ... -
Review of transmission tower testing stations around the world
(Procedia Engineering, 2013)The present study introduces and compares several testing stations around the world. The scope of performing tower testing is addressed, followed by singular requirements of tower testing stations and main standards related ... -
Increasing energy efficiency of the translucent enclosure walls of a building
(Procedia Engineering, 2013)Until the 21st century, in the countries of cold climate, windows have been considered to be the elements of the buildings, through which large quantities of heat leak in the heating season. Nowadays modern technologies ... -
The dynamic amplification factor of the bridges in Latvia
(Procedia Engineering, 2013)The paper presents a study of the dynamic amplification factors (DAF) obtained from the results of the dynamic load tests of bridges carried out from 1990 untill 2012 in Latvia. The study of the DAF was carried out for ... -
Early hydration of calcium aluminate cement blended with spent FCC catalyst at two temperatures
(Procedia Engineering, 2013)The early hydration (up to 24h) of calcium aluminate cement (Al2O3 min. 40%) blended with spent FCC catalyst at two temperatures i.e. 10 °C and 25 °C was investigated. The calorimetric measurements were used to study ... -
Materials for advanced heat storage in buildings
(Procedia Engineering, 2013)The costs of fuels and energy in the Czech Republic have rapidly increased in the last two decades. This situation in the energy market has bolstered the interest in the development of heating and cooling systems utilizing ... -
Pitfalls of excessive owner occupied housing
