Dn. Farhey et al., RESISTANCE MECHANISM MODEL FOR REINFORCED-CONCRETE FLAT SLAB-COLUMN FRAME CONNECTIONS, ACI structural journal, 94(6), 1997, pp. 653-662
Results of an analytical and theoretical study on reinforced concrete
fiat slab-column frames connections, subjected to lateral and vertical
lends front earthquake and gravity, are presented. The study investig
ates the plastic behavior; and load transfer and final failure mechani
sms. An idealized model of the response is presented, based on observa
tions of tests repelled in literature, and particularly on tests carri
ed out by the authors and followed by detailed postmortem dissections
of the failure zones. Based on the idealized resistance mechanism mode
l, an analytical method is presented for graphically predicting the en
tire moment-rotation response envelope of a connection during the diff
erent loading stages, detailing the varying relative fractions of the
resistance components. The numerical solutions are compared with curre
nt calculation methods on full-subassemblage experimental results.
