Book Description
These volumes contain the edited documents presented at the NATO-Sponsored Advanced Research Workshop (ARW) on Partial Pre8tre88ing, from Theory to Practice, held at the CEBTP Research Centre of Saint-Remy-Ies-Chevreuse, France, June 18-22, 1984. The workshop was a direct extension of the International Symposium on Nonlinearity and Continuity in Pre8tre88ed Concrete, organized by the editor at the University of Waterloo, Waterloo, Canada, July 4-6, 1983. The organization of the NATO-ARW on Partial Prestressing was prompted by the need to explain and reduce the wide dirrerences of expert oph:iipn· on the subject, which make more difficult the accep tance of partial prestressing by the profession at large. Specifically, the workshop attempted to: - produce a more unified picture of partial presetressing, by con fronting and, where possible, reconciling some conflicting American and European views on this subject; - bring theoretical advances on partial prestressing within the grasp of engineering practice; - provide the required background for developing some guidelines on the use of partial prestressing, in agreement with existing structural concrete standards. The five themes selected for the workshop agenda were: (1) Problems of Partially Prestressed Concrete (PPC). (2) Partially Prestressed Concrete Members: Static Loading. (3) PPC Members: Repeated and Dynamic Loadings. (4) Continuity in Partially Prestressed Concrete. (5) Practice of Partial Prestressing.

ABSTRACT: Given the prospective threat of a blast or impact load causing severe damage to a structural element or system, it is critical to investigate and understand the dynamic behavior and potential failure modes of such members. One method used to perform such an analysis in a computationally efficient manner is the programming code Dynamic Structural Analysis Suite (DSAS). The presented study's intent is to evaluate the incurrence of plastic hinges via DSAS and inspect the resultant behavior of both normal strength reinforced concrete and ultra high performance concrete columns under severe loads. Ultra high performance concrete (UHPC) is an emerging engineering technology characterized by increased strength and durability compared with normal and high performance concretes. As a relatively new material, UHPC remains to be fully characterized, and to study the material's response under simulated loading conditions contributes to widening its use, especially with respect to protective applications. As a particularly vulnerable structural element under blast and impact loadings, columns are the specific interest of the study. To introduce the dynamic behavior of concrete columns, the analytical methods and models detailed in engineering literature 18 are first reviewed. The study then examines the process by which DSAS was adjusted to approximate the plastic hinge formation and respective curvature along the column length, allowing for the evaluation of concrete columns' behavioral response under various boundary and load conditions. The considered normal strength concrete and UHPC columns are subsequently compared with the output from the finite element program ABAQUS for corresponding material models as well as the simulated behavior of each other using DSAS. Such comparisons respectively intend to validate the generated models and to demonstrate the elevated properties of UHPC. Given the pr.
