Controlled rocking steel braced frames (CRSBFs) are modern systems for resilient building structures known their effective energy dissipation and self-centering features. In a CRSBF, post-tensioned (PT) strands shear fuses the distinct features providing mechanisms. As relatively new structural system, there is need to study this system’s optimal design. Control co-design has gained interest in...

dual systems of steel moment frame and reinforced concrete shear wall have combined the advantages of steel frames and reinforced concrete shear wall. these walls have increased the lateral stiffness of steel frames and have reduced seismic demands on steel frames thus providing opportunities to use such system. in this research intermediate dual system of steel moment frame was chosen with int...
