Abstract  

The work details of which are presented in this thesis can be divided into three parts. i)-Study pertaining to nonlinear analysis of beams. To the best of author's knowledge so far the researchers have developed only solid two-noded and three-noded line elements for the elastic analysis of reinforced concrete beams. Therefore layered isoparametric finite element has been formulated in order to obtain full load-displacement history, behavior of reinforced concrete beam in post-elastic range, concentration and/or distribution and redistribution of stresses at different stages of loading and estimate the-ultimate load both in terms of flexure as well as shear. ii). As will be shown in the thesis with the help of literature review, all the work regarding the formulation of nonlinear finite element for the analysis of slabs has remained confined to the prediction of the flexural load at failure, but so far no shear failure criteria has been developed or incorporated in such computer programs to estimate the ultimate strength in terms of shear. This may not be very important for common slabs, but for specialized form of reinforced concrete plates such as, flat slabs directly resting on columns or coupling slabs of a shear wall structure where shear is predominating factor it be-comes imperative to estimate the shear strength before proceeding further to complete design of the structure. Therefore using a four-noded rectangular layered plate bending element with five degrees of freedom at each node a computer programe originally used for flexural non-linear analysis of slabs has been substantially modified by the author to estimate shear strength as well. iii). The va1idity of the theoretical work has been checked by conducting experimental study and comparing results with the theoretical ones. iv). In order to make sure that the programs were really good for all the situations and sets of material properties, a few of the slabs and beams were made up using broken pieces of bricks as coarse aggregate. There was a good agreement between the theoretical and experimental results.
