Abstract :
Time period ratios for first longitudinal mode are found to increases as the degree of skewness and curvature increases, whereas mode participation factor decreases with increase in curvature and increases with increase in skewness for the same mode. Mode participation factor of first transverse (in-plane) vibration mode increases with increase in both skew and curvature angle. Results of response spectrum analysis indicates that all the three principal moments experience higher moment demand under transverse components of seismic excitations. For skew-curved bridges moment demand gets increases with increase in curvature in most of the cases. However, increase in skew angle causes decrease in moment demand in most cases.
