Structural concrete members often show great deviation in structural performance from that predicted by the current methods. In certain cases the predications considerably underestimate their capabilities, while in others the predictions are clearly unsafe as they overestimate the ability of the structural member to perform in a prescribed manner. Therefore, the theoretical basis of current design methods requires an extensive revision if the methods are to yield, consistently realistic predictions. In the authors’ first book Structural Concrete: Finite element analysis for limit-state design (Thomas Telford, 1995) a method based on formal finite-element modelling of structural concrete with realistic material properties was described. In this new book, a simplified method is presented which needs calculations which are no more complex calculations than those required by the current codes. It involves identifying the regions of a structural member or structure through which the external load is transmitted from its point of application to the supports and then strengthening these regions as required. As most of these regions enclose the trajectories of internal compression actions the technique has been called the""Compressive Force Path Method"". This book will provide design offices with a practical and easily applied method for the design of a concrete structure, which is fully compatible with the its behaviour (as described by valid experimental evidence) at both the material and structural levels. |
