This paper presents an engineering survey based on experience of the authors during design and expertise of complex building structures in period of 2000–2014. Legal, organizational and technical aspects in a procedure of changes in structural design documentation are investigated. Separate actions for implementing changes according to legislative documents in Lithuania in technical and working structural projects are presented by a general algorithm. Actual questions about sequence in proceeding with local and global analytical calculations during designing of complex structures and peculiarities of processing revised structural drawings and text documents are described in this paper. Relevance of the subject is illustrated by an example of a successful decision in solving common construction and design problems of an office building in Vilnius. Finally, conclusions and recommendations are given. This paper is an investigation of the considered problem and is designated for science researchers in civil engineering, educational and public organizations working with refinement of the design procedures and project documentation handling, and for practicing engineers.

The analysis of a method for the design of reinforced concrete structures exposed to fire temperatures is presented in the article. The main essential factors which must be evaluated in the design of structures and their parts to provide their adequate carrying capacity and ability to prevent fire spread are analyzed. In fire design it is necessary to take into account the behaviour of structural system exposed to fire temperatures, the possible effect of heat and positive effects of active and passive protection systems against fire and the consequences of collapse of the structure. The method is intended for buildings, fire load is associated with the building and its use. At the same time thermal and mechanical actions for structures exposed to fire are considered. Article in Lithuanian. Nauja Europos sąjungos gaisro temperatūrų veikiamų gelžbetoninių konstrukcijų projektavimo metodika Santrauka.Straipsnyje pateikta naujos gaisro temperatūrų veikiamu gelžbetoninių konstrukcijų projektavimo metodikos analizė. Išanalizuoti pagrindiniai esminiai veiksniai, kuriuos privalu įvertinti projektuojant konstrukcijas ir jų dalis taip, kad jos būtu pakankamos laikomosios galios ir reikiamai ribotų gaisro plitimą. Rengiant gaisrinius projektus, reikia įvertinti konstrukcinės sistemos elgseną veikiant gaisro temperatūroms, galimą šilumos poveikį ir teigiamus aktyviųjų ir pasyviųjų apsaugos prieš gaisrą sistemų efektus kartu su šių trijų savybių neapibrėžtumais ir konstrukcijos griuvimo pasekmėmis. Metodika skirta pastatams, gaisro apkrovą siejant su pastatu ir jo naudojimu. Kartu nagrinėjami gaisro veikiamų konstrukcijų šiluminiai ir mechaniniai poveikiai. Reikšminiai žodžiai:gaisro temperatūros,konstrukcijų projektavimas,šiluminiai ir mechaniniai poveikiai. First Published Online: 21 Oct 2010
