Investigation of R-Factor for steel moment frame combined with cold-formed steel structures under different load patterns using pushover analysis
The use of Lightweight Steel Frames (LSF) has grown considerably in recent years all over the world due to its unique advantages such as being cost-effective and light-weight, easy and quick installment. Another application is to use them in order to increase the number of new floors on the existing...
