description: Seismic performance assessment is of critical importance for structures in regions where earthquakes are prevalent. Identifying the inelastic capacity of structures undergoing seismic loads is one of the main concerns in seismic structural design. Such assessment in terms of determining the inelastic capacity of structures is often performed in laboratories at universities, government, and industrial facilities through quasi-static cyclic loading test programs. In these programs, selecting an appropriate loading protocol is crucial for achieving an accurate assessment of the inelastic capacity. Appropriate loading protocols need to be representative of the seismic demands to which a structural component may be subjected during seismic events. A standard loading protocol available in the literature will not necessarily yield a meaningful response. For the quasi-static cyclic test program, a loading protocol should be developed specifically to the site, structural component, and system of the structure. In this study, an Incremental Dynamic Analysis-based approach is introduced to develop component-specific quasi-static cyclic loading protocols, which is illustrated for a single-column reinforced concrete bridge bent in Vancouver, British Columbia. The sensitivity of the development procedure to different design parameters (e.g., mechanical, and geometric properties) was evaluated through a factorial analysis to propose a single cyclic loading protocol for several bridge pier designs. Here, target displacement ductility demand levels of two, four, and eight, and crustal, subcrustal, and subduction earthquakes were considered. The number of inelastic cycles and cumulative ductility damage were the primary target demand parameters in the loading protocol development. Conventional loading protocols were found unrealistically more damaging than those proposed for crustal and subcrustal earthquakes. The proposed loading protocols for subduction earthquakes were consistent …
