Technical and economic assessment of building performance through light metal frame (LSF)

Abstract

Using LSF in recent years has been remarkable in many countries of the world due to many advantages, including speed and high quality construction and good seismic performance, the need to high quality construction, durability and useful life of buildings, improving the seismic performance buildings under construction, and attempting to resolve lack of housing or other spaces and buildings in most countries explain the necessity of using new technologies and new production methods rather than traditional systems and inefficient buildings. In order to determine the differences between LSF system and traditional systems prevalent in the country in the construction of low-rise buildings, several different projects using structural systems of ordinary steel, concrete structures and LSF system design and the results obtained were compared. Projects include three buildings with two, three, and five floors that are designed using all three methods and relatively comprehensive comparison of results is presented. The results show that using LSF has seismic appropriate performance due to its ability for reducing the relative location, reducing structural weight by approximately 40% greater than the metal currency, reducing the consumption of concrete by about 60% compared to concrete structures common and 30% greater than the metal current performance. By examining the numerical differences between the design criteria LSF systems and traditional systems of construction of the country, LSF system is very convenient and safe to make effective use of its advantages that localization and training systems in decision-making of different sectors including Building and Housing Research Center is recommended
