Abstract

Accelerated bridge construction (ABC) has recently gained popularity among state departments of transportation in the U.S. to minimize construction costs, time, and waste, and optimize the use of materials. This research focused on the connection details between hollow-core fiber-reinforced polymer-concrete-steel columns for ABC construction and their foundations. Three foundation anchorage details were tested with multiple embedment lengths into the footing to evaluate the connection’s capability to transfer bending moment and achieve the ultimate column flexural and shear capacities. Nine column-footing (CF) specimens were cast in a form of steel pipe embedded to the footing and tested to failure. Seven specimens were cast to study the effect of embedment length, diameter-to-thickness ratio, compressive strength of the concrete footing, and end-of-column anchorage on monolithically cast connection capacity. Two specimens utilizing a socketed connection filled with ultra-high-performance concrete (UHPC), designed to represent connection of precast elements, were also cast and tested to failure. Embedment length had a significant effect on the performance of the CF connection. The short embedment lengths tested (1.6D_i and 1.68D_i) were not sufficient to develop the steel pipe flexural strength for the monolithic connection specimens with a normal-strength concrete footing. However, the use of socketed connection with UHPC, high-strength concrete footing, and welding a series of lugs to the embedded pipe prevented the steel pipe from pulling out, to some extent. The longer 1.8D_i embedment length resulted in the steel pipe reaching its flexural strength without pullout, whether using the socketed connection with UHPC, high-strength concrete, or normal-strength concrete.
