Abstract:
The effect of the flexibility of the floor slabs on the seismic response of crosswall buildings was investigated both for the case of a uniform base motion (normal assumption) and for the case of an earthquake motion travelling horizontally with a finite velocity of propagation. A series of parametric studies were conducted, the results indicate that the slab flexibility should be taken into account when dealing with relatively short buildings, with five or less stories, and in the first few floors of all buildings of the type studied when there are important torsional effects induced by a nonuniform ground excitation.
