Effect of infilled panel on the nonlinear dynamic response of reinforced concete plane frames

Abstract EN

Studying the effects of the static and dynamic loads on structures is very essential, especially in zones where the structures are exposed to severe earthquakes.

In the present study a finite element program is developed for static and dynamic analysis of reinforced concrete plane frames.

The main concern is to study the effects of infilled panels on the behavior of this type of structure.

One dimensional Beam-Column Elements are used to represent the frame members and Lumped Plasticity Model is used to model the nonlinearity of these elements.

Modified Four-node isoparametric plane stress elements with 3-DOF per node, are used to represent infilled panels.

Connection between infill element and frame is either assumed to be perfect or by linkage elements which allow separation between the two types of elements.

Two programs are developed one for the static and the other for the dynamic analysis and the validity of the developed programs have been checked and the predicted results indicated a good agreement with the published experimental and theoretical results.
