Seismic responses of two typical large-span structures to uniform vertical seismic excitation are investigated and the effects of multi-support vertical excitation on the responses are checked.

The time-dependent DFT (TD-DFT), CIS and TD-HF studies have been performed on the UV-spectrum of phenanthrene. Based on the optimized geometries, the vertical excitation energies were calculated.

At PM3/CIS level, the vertical excitation spectra were calculated and the vertical excitation energies and corresponding oscillator strength from the ground states to the excited states are obtained.
