The most important
principle of the earthquake-resistant design of reinforced concrete structures
is that the structural elements must carry both vertical loads and horizontal
loads as a whole. For this reason, it is required that the structural elements
carry their own weight with sufficient safety and the loads arose from external
forces must be transferred safely to the load carrying vertical elements.
However, discontinuity of the slabs disturbs the integrity of the structures and
causes problems in transferring earthquake loads to the structural elements. In
this study, the effect of slab discontinuity in plan on seismic behaviors of
multi - storey reinforced concrete structures was investigated by using
incremental linear dynamic analysis method. To investigate this irregularity
situation, one regular and three irregular multi-storey reinforced concrete
building models were selected. Dynamic envelopes of the structures were obtained
from the analysis results and compared with each other. Thus, it was observed
that the irregular structures subjected to more shear force than the regular
structure.
