Simplified Analytical Modeling for Emulative Cast-in-Place Connections for Accelerated Bridge Construction in Seismic Zones

Accelerated bridge construction (ABC) offers advantages such as rapid construction, limited traffic disruption, cost savings for the formwork, more accuracy in construction due to prefabrication, better quality control, higher durability, reduced weight of the bridge structure, enhanced safety, and less environmental impacts. The research investigates analytical modeling of a precast bent with emulative monolithic connections. The column-to-footing connection is member socket, while the column-to-cap beam connection is grouted ducts. These connections intend to emulate the traditional formation of plastic hinges in monolithic bridge piers during an earthquake. The paper presents simplified analytical procedures based on moment-curvature analysis and displacement-based design that could be used by bridge practitioners and researcher to construct the backbone curve for the emulative monolithic bent. It further discusses Takeda-Thin hysteretic rule with appropriate parameters that can capture the cyclic response of the bent under quasi-static loading. Analytical results were compared against experimental data. It is shown that the simplified analytical procedure proposed in this research can predict the response of the bent adequately.
