Seismic performance assessment of reinforced concrete bridge columns under variable axial load

The current paper aims to assess analytically the seismic performance of reinforced concrete bridge columns under variable axial load. Variable axial load is very important to the ductility, strength, stiffness and energy dissipation of reinforced concrete bridge columns. The effects of variable axial loads on bridge columns are analysed to obtain a more realistic characterisation of the actual performance and capacity of bridge columns. A...
