다국어 초록 (Multilingual Abstract)

This work is based on a nonlinear finite-element model with proven capacity for yieldingrealistic predictions of the response of reinforced-concrete structures under static monotonically-increasing loading. In it, the material description relies essentially on the two key properties of triaxiality and brittleness and, thus, is simpler than those of most other material models in use. In this article, the finiteelement program is successfully used in investigating the behaviour of a series of RC walls under static cyclic loading. This type of loading offers a more strenuous test of the validity of the proposed program since cracks continuously form and close during each load cycle. Such a test is considered to be essentialbefore attempting to use the program for the analysis of concrete structures under seismic excitation inorder to ensure that the solution procedure adopted is numerically stable and can accurately predict thebehaviour of RC structures under such earthquake-loading conditions. This is achieved through acomparative study between the numerical predictions obtained presently from the program and availableexperimental data.
