资源简介：
The seismic performance of the precast system was evaluated with quasi-static tests of two column-to-footing sub-assemblies. In this column-to-footing sub-assembly, a ductile fiber-reinforced concrete (HyFRC) was used in the plastic hinge region and stainless steel reinforcing bars were used in the column.
The column-to-spread-footing subassembly had a cantilever height of 66 in. and a column diameter of 20 in (42% scale). The specimen was subjected to a constant axial Load of 159 kips and a quasi-static displacement history based on the NEHRP recommendations for precast structural walls.
The lateral displacement history consisted of ten four-cycle sets. Each set had target peak values of 1.2X, 1.44X, 1.44X, and 0.48X, where X is the maximum target drift from the previous set. The maximum target drift of the first set was selected so that the column would remain elastic throughout the duration of the first four cycles (X = 0.167 in.).
