Title: Moment Rotation Characteristics of Flat Plate and Column Systems
Author(s): J. F. Mulcahy and J. M. Rotter
Publication: Journal Proceedings
Appears on pages(s): 85-92
Keywords: columns (supports); connections; concrete slabs; flat concrete plates; lateral pressure; loads (forces); moments; stiffness.
Abstract:The response of flat plane and column structures to lateral loading is closely associated with the stiffness of the slab/column joints. Many previous theoretical and experimental investigations have studied the linear elastic response of sway systems but few experimental results are available on the nonlinear behavior of concrete slabs/column joints. Results from experiments on reinforced concrete models are presented and show a nonlinear response from very low load levels. The behavior of the test specimens is compared with both linear elastic and empirical predictions.The results are also compared with an equvilant slab derived from th equvilant frame method of ACI 318-77. This is found to give a closer description of the observed behavior than the elastic theories.
