light steel frame (lsf) systems: a suitable structure for building in irans earthquake-stricken areas (a review)

According to the statistical data of the iranian seismological center in the first three months of 1398, a total of around 2880 earthquakes were recorded and determined in iran and borderline regions. the largest earthquakes with the richter magnitude scales of 4-5.1 occurred in kermanshah province, iran, and its suburbs. in addition, a severe earthquake occursin iran every 7 years on average which leads to dramatically high financial loss and casualties. according to earthquakeinduced losses and damages, the building industry has intended to lighten and provide industrial construction of structuresto facilitate better support against seismic forces. in this respect, light-weight steel structures have been applied by engineers as one of the excellent industrialization and lightening approaches. this modern building system has greatly welcomed in developed countries and has used as an alternative to traditional systems. this system can be employed for rebuilding in earthquake-stricken areas and construction in prone-to-earthquake regions. this study was conducted aiming at reviewing features of light-weight steel structure to be used in prone-to-earthquake and earthquake-stricken areas.
