    A first approach to optimum design of cable supported bridges using load path method

    Born as a method to design strut-and-tie models in reinforced concrete structures, the load path method (LPM) shows its effectiveness in the easy perception of the physical behaviour of a structure, from its global behaviour to the most accurate details. In this paper, starting from the interpretation of cable-supported bridge behaviour using LPM, two different approaches are proposed for the shape optimum design of this particular type of bridge

    The case that the researchers had to analyse on behalf of the Public Prosecutor's Office, was the initial failure that triggered the unexpected collapse of a reinforced concrete building during the night of November 11th, 1999. They also had to reconstruct the event starting from the individuation of the causes of such crumbling that is still remembered for its serious sacrifice of human lives. Together with the detailed report of the case, the paper intends to make a useful contribution to the crucial topic concerning the choice of the most appropriate method to perform this sort of autopsy, without neglecting any technical guideline

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
