Abstract

Morrison et al. (2015) proposed a controlled heating process for steel in which every property of steel remains constant except its strength (i.e. yielding strength). This novel idea is used for the weakening of beam sections as reduced beam section (RBS) moment connections do. Therefore, plastic hinges develop away from the column face. In this paper, in addition to study the near-fault effects on this type of moment connections, parametric analyses are performed. Moreover, the seismic performance of this new weakened connection is evaluated using nonlinear static analyses. With regards to the obtained results, the best region of beam for heating is determined and seismic performance factors are proposed.
