The aim of the Iranian Journal of Science and Technology is to foster the growth of scientific research among Iranian engineers and scientists and to provide a medium by means of which the fruits of these researches may be brought to the attention of the world’s civil Engineering communities. This transaction focuses on all aspects of Civil Engineeringand will accept the original research contributions (previously unpublished) from all areas of established engineering disciplines. The papers may be theoretical, experimental or both. The journal publishes original papers within the broad field of civil engineering which include, but are not limited to, the following:-Structural engineering-Earthquake engineering-Concrete engineering-Construction management-Steel structures-Engineering mechanics-Water resources engineering-Hydraulic engineering-Hydraulic structures-Environmental engineering-Soil mechanics-Foundation engineering-Geotechnical engineering-Transportation engineering-Surveying and geomatics.
