The Behavior Under Load of the Portal Gantry Cranes, Refering to Strength, Stiffness and Stability Part Ii – Experimental Determinations of the Field of Stresses and Strains

Abstract

<p>This paper presents some experimental determinations concerning the dynamics under changing loads of the forces in windbracings and of the stress in the elements sensitive to fracture.</p><p>The experiments are achieved after a preliminary analysis of the potential failure zones of the crane is done.</p><p>The achievement of the experiments is based on the following logical structure of the experiment: the preparation of the measurement devices and of the used transducers, the achievement of an assembling diagram, the establishment of the quantities (parameters) which will be recorded, the execution of the mounting and of the experimental determinations, the presentation of diagrams and/or tables, conclusions, comparisons to the theoretical data established in the former paper. The paper presents the field of stresses and sectional strains in windbracings. </p>
