The nonlinear stress-strain relationship of a thin plate or stiffened panel under in-plane load is represented by a load-shortening curve. The curves are used to evaluate the buckling and ultimate collapse behaviour of these structural elements, and furthermore forming the input data to analytical progressive collapse methods for large scale box girder structures such as ships. This paper develops a novel analytical method that predicts the load-shortening curve of plates and stiffened panels under cyclic in-plane load. This provides the framework to account for load reversals in an enhanced cyclic progressive collapse method. A parametric study using nonlinear finite element analysis is completed to investigate the characteristic behaviour of simply supported plates under cyclic compression and tension. The investigation covers a range of aspect ratios and slenderness ratios typical for ship-type structures. Single-cycle and ten-cycle loading protocols are applied, which demonstrate progressive reduction in strength and stiffness together with a response convergence after several cycles. An analytical method to predict multi-cycle load-shortening behaviour is then derived using a response and updating rule based on the observed characteristics from the parametric study. A validation of the analytical method is performed on a range of unstiffened plates and stiffened panels under various cyclic loading protocols. A good comparison with the results of finite element analysis is obtained, which confirms the validity of the proposed analytical method.

“…Plastic behavior was defined in a tabular form with a stress strain curve from [26] converted into true stress and strain values and inserted in ABAQUS in terms of yield stress and corresponding plastic strain [25]. Other than that, a combined isotropic-kinematic hardening has been used to capture the behavior under cyclic loading with calibrated parameters from [33].…”

Reinforced concrete flat plate structures have been used in the construction industry since the start of the 20th century due to their architectural flexibility and economy. Through the years the structures were mainly designed to carry gravity loads due to their high flexibility in their connection regions. Unfortunately, these structures may sometimes be subjected to lateral and gravity loads due to unexpected natural phenomenon such as earthquakes. The information on behavior of these structures under such loading condition is limited. This paper presents parametric study on isolated flat plate connections under combined gravity and lateral loads using a non-linear finite element analysis. The numerical model for the connections was developed using ABAQUS in which plasticity model for concrete and an elastic-plastic model for steel reinforcement was employed. The model was validated with an experimental test, conducted by other researchers, of similar loading condition. The results of parametric study on the effect of column geometry and service openings adjacent to the column are presented. Among the parameters, the effect of column geometry was found to have significant effects on the connection behavior.
