In the seismic design of a reinforced concrete building, selecting appropriate response reduction factor (R) is vital for building’s response. Indian Standard (IS) 1893-2016 provides R values 3 and 5 ordinary moment resisting frames special frames, respectively. As factors are used to incorporate non-linearity, selection should be based on performance in terms resilience. Since IS does not prov...

The progressive collapse of the building structures due to accidents has become a hot research topic of civil engineering all around the world. The researches and designs on progressive collapse are based on accurately simulation for the failure process of whole structural systems. However, due to the complicated material and geometric nonlinearity and large computational workload in collapse s...

We present a mixed-integer nonlinear programming (MINLP) formulation to achieve minimum-cost designs for reinforced concrete (RC) structures that satisfy building code requirements. The objective function includes material and labor costs for concrete, steel reinforcing bars, and formwork according to typical contractor methods. Restrictions enforce correct geometry of the cross-section dimensi...

Several existing reinforced concrete (RC) buildings fail to conform with current seismic codes, increasing its susceptibility damage and collapse during earthquakes. A concern for building upgrading rehabilitation has grown considerably in the last decades. However, there is limited information related performance of RC retrofitted steel jacketing. Retrofitting leads different techniques that h...

A performance-based seismic design (PBSD) method is aimed at controlling the structural damage based on precise estimations of proper response parameters. PBSD method evaluates the performance of a building frame for any seismic hazard, the building may experience. Use of this method for vertical irregular building is verified with comparison of conventional method. Vertical irregular frame is ...
