The paper addresses the seismic behavior of buildings with torsional eccentricies to a complex seismic wave environment. Specifically, the paper investigates the effects of nonsynchroneus seismic motion on a L-shaped building with significant torsional eccentricity. The building represents a typical concrete-steel composite industrial structure sitting on a soft soil deposit with a shear wave velocity of 1000 fps. The foundation consists of isolated foundations under the walls and columns. The incoherent seismic motion at the foundation level is idealized by a homogeneus stochastic field with isotropic/anisotropic correlation structure. The directional wave passage effect is introduced by time lags between the soil motions at different locations. The seismic SSI analysis was performed using the ACS SASSI computer code which includes the capability of considering nonsynchroneus input excitations. Introduction The severe effects of nonsynchroneous seismic motions, including incoherency... |
