Abstract

During the recent years, the use of cold formed steel structures has expanded all over the country in housing industry, and they are employed in mass constructions and great projects. Apart from the advantages of this construction system, like high speed execution and lightness, lack of proper performances in different construction’s stages of design, constructions and installations have caused many difficulties and problems in use of this modern structural system. Hence, there is a concern that this opportunity would be converted to a threat for the country’s construction industry. In this paper, an attempt is made to identify the barriers and problems existing in cold formed steel constructions. It is hoped that by precise planning and the efforts of the authorities, these problems will be minimized.

In the present study, while conducting a case study on a large number of buildings which constructed by LSF, interview with some expert executives, engineers, professors and beneficiaries were performed. The answered questionnaires then analyzed by network analysis process, Dematel and Delphi methods. After that, the most effective factors in lowering quality of this kind of structural systems were identified and ranked. Finally, some suggestions were made in order to improve the quality of this system.
