In the present work; the recently introduced parameter Q which is a ratio of the effective modal masses is modified and used to define the torsional irregularity of build [...]

At present, inelastic static pushover analysis is widely used in engineering practice to predict seismic capacity of building structures because of its simplicity compare [...]

12 eccentrically braced steel frames are designed according to LRFD (1999) and ASCE 7-05. Capacity-based design principles are based on AISC Seismic Provisions (2005). So [...]

In capacity-based design of eccentrically braced steel frames according to AISC-Seismic Provisions (2005), while the links are sized for the load combinations specified b [...]
