摘要

The paper deals with application of capacity spectrum method which is extended to provide estimate for seismic demands for specific type of structure and variable boundary conditions. Flat slab-R/C wall systems are considered. Flexible shallow wall foundations are used because of soil deformations. Only elastic soil properties are considered. Foundation motion is implemented assuming new additional degrees of freedom instead of standard fixed end. The only rocking motion of the footing is accounted for as the most essential. The influence of foundation flexibility on the seismic demands is evaluated using capacity spectrum method. Numerical results for a single wall and for overall structure are graphically represented. It is concluded that soil conditions are very important for the design seismic response of wall systems. Some important conclusions are made.
