This paper focuses on internal membrane forces
in reinforced concrete slabs that form diaphragms to
transmit horizontal forces like seismic loads to vertical
elements like columns and walls. It is found that considerable
axial forces exist in the slab near columns in flat plate
systems supported by columns and larger axial forces exist in
slabs and their beams along walls lines in slabs supported by
walls, where horizontal forces are resisted by the walls. These
internal forces especially tension must be considered in the
design of the slabs and the beams. This issue should be taken
into account in using computer softwares which do not design
slabs and beams for axial forces.
