Result of seismic response analysis of a large span cable based bridge with inconsistent inputs is presented in a conjugated paper and is further deal with in this paper. The results from synthesized motions for the same earthquake source and same distance to the rupture show a large difference. They are compared with characteristics of the inputs in this paper. The effect of the motion amplitudes and the coherency between the input motions at the two ends of the main girder on the maximum response displacements and internal forces are pointed out.

Seismic response of a large span cable based bridge with inconsistent inputs is analyzed in this paper. The bridge model is built by the function of finite element software ANSYS. The free vibration characteristics of the bridge are analyzed by Lanczos Vector Iterative method. The first and the twentieth free vibration frequencies are 0.06808 Hz and 0.54392 Hz respectively. A set of motions of consistent, traveling wave and synthesized (inconsistent) are adopted as inputs at the two supports. The lengthwise, lateral and vertical displacements at the span center and quarter span of the main girder, at the tops of the supporting towers, and the internal forces in the girder and at the base of the towers are calculated. The result shows obviously the necessity to take into account inconsistent input in seismic response analysis of large span bridge.

Based on one 240-meter-high special-shaped RC chimney, the structure’s dynamic performance and elastic-plastic seismic response analysis has been studied in detail. From the analysis, it demonstrates the weak areas in the chimney. The interlayer displacement angle about corresponding performance points under four kinds of loading mode were also acuired, and the response of four loading patterns were analyzed.
