The assessment of the respoonse of reinforced concrete frames to earthquakes is essential in many parts of the world. Therefore, the design and assessment of the structures which are likely to be subjected to such actions require the application of non-linear analysis using finite element techniques of different degrees of complexity. This state-of-the-art report, examines the behaviour of individual frame members subjected to the cyclic actions arising in seismically loaded frames; i.e. slender flexure-dominated beams, short columns and beam-column joints. The report also considers global inelastic frame behaviour and its modelling, and the peculiarities of the behaviour of masonry-filled frames.
