Romania is one of the European countries where the steel industry started inthe 18th century. In the second part of the 19th century the Austrian RailwaysSTEG company developed in the western part of the country - Resita - theproduction of steel and introduced modem European technologies.

A new relevant development was realised after the Second World War inthe period of centralised economy when the output of industrial steel was 14million tonnes/year. After the political changes in 1989 production droppedup to 6 million tonnes/year (Fig. 1). The reason was the loss of some tra-ditional markets (COMECOM and Third Countries Area) and also the restruc-turing of the national economy.

In order to integrate Romania into the European Union, the RomanianGovernment applied for a PHARE supported study concerning the restructur-ing policy in the field of the steelmaking industry. According to this study,

?? ZO-25% of total steel production can be estimated to be used by theconstructional steel work industry

?? 20% export?? 5560% for the machinery industry and other fields.

An important fact should be mentioned: starting with 1996 Romania is rep-resented by the Technical University of Timisoara as a full member in theEuropean Convention for Constructional Steelwork. In 1997 Romania wonone of the ECCS Awards for Steel Construction.

Until 1988 steel use in residential and non-residential buildings was limited;the main field of steel constructions was heavy industry. Since 1990 bothnon-residential and light industrial buildings have been made mainly in steel.Following the continuous development of the private branch of the Romanianeconomy, different light gauge steel buildings systems have been introducedin Romania, among them Astron, Butler and Lindab. The multi-storey steelbuildings started to use modem structure types, welded and bolted and alsoEuropean profiles (IPE, HEA, HEB). At present the Romanian industry doesnot produce such profiles; consequently they are either imported or welded.

The price of usual steelwork production varies between 0.8-1~5 USD/kg,depending mainly on the quality of steel, the complexity of processing andthe type of corrosion protection. The price structure is:

?? material = 40%?? energy, bank interest, taxes = 40%?? wages = 20%

The paper presents some relevant examples of steel constructions erected inRomania in recent years (multi-storey steel concrete composite building, lightgauge steel industrial building, a market place and a bridge).

Another important trend is the adoption of the Eurocode framework. TheRomanian Codes for Steel Structures valid at present, have been issued in theearly 70s; these codes used the first order elastic analysis without consideringglobal imperfections, but included European buckling curves. In 1997 theMinistry for Public Works and Territory Management (MLPAT) launched anational programme in order to elaborate new technical codes in Civil Engin-eering and to adopt the whole Eurocode complex. This programme is meantto be developed in the period 1997-2000, aiming to issue the Romanian Euro-code National Application Documents.

The development trends in constructional steelwork industry in Romaniaare:- concerning the steel making industry:

- concerning protection against corrosion?? the introduction of metal and plastic coating

- concerning the main jelds of utilisation?? development of light gauge steel systems for industry, non-residential

buildings and housing?? multi-storey steel buildings with composite steel concrete floors and

bolted or welded beam-to-column connections?? composite bridges for motorways and steel bridges for railways.
