Thus we see an increase in gravity and lateral forces and Accepted 25 June 2019 consequently the beam and column dimensions of elements increase. In this paper by taking Available online several samples of buildings with steel frames and number of different floors and use of different 25 June 2019 Keywords materials as well as various gravity and lateral load-bearing systems this issue was investigated. It Optimization was observed that by the use of steel bracing system in both directions of buildings with steel Steel buildings frames each different load-bearing results in minimum weight loading per unit surface of the Lightweight skeleton of structure. It was also observed more effect of lightweight construction by increasing the number of floors for all lateral load-bearing systems. Effects of lightweight construction for different lateral load-bearing systems was investigated and we observed that the effects of lightweight construction commonly used for buildings with moment frame system in both directions were more
