| Abstract: | The stationary random responses of tow layer spatial frame subjected to spatially coherent excitations are investigated and the pseudo static, the dynamic, and the total response variations are calculated. The results, together with those obtained by neglecting ground motion phase shifts and those by neglecting ground motion coherency losses are compared with the corresponding structural responses variation to a single input. The influence of the eccentricity is analyzed and some useful conclusions are given. |
