Abstract: Compared to cast-in-place bridge piers, precast piers can accelerate bridge construction, but their use in seismic systems is challenging. High-strength bars (≥500  MPa) incorporated with precast piers can further expedite ...

Abstract: Transverse post-tensioning is commonly introduced in top slabs of concrete box girders to control transverse tensile stresses induced by dead and live wheel loads. However, longitudinal cracks with a definite pattern have ...
