STUDYING ON THE CAUSES OF THE VERTICAL CRACKS APPEARED ON THE FAN SHAPED REINFORCED CONCRETE PIERS

Abstract

The fan-shaped concrete piers have been widely applied in urban crossover bridges in Vietnam due to the advantages of aesthetic and material saving. However, during the construction stage as well as operation stage, vertical cracks occurred on the top of the piers in some bridges. The paper presents the research on the causes appearing the cracks on the fan-shaped concrete pier based on strut - tie model, finite element method and comparison with measurement data for proposing a suitable design method for similar bridges in the future.
