Static and Dynamic Analysis of the “Piedra Movediza” Replica Rock, Argentina

Abstract

This paper describes the activities involved in the development of the project “Piedra Movediza” Replica, located on the La Movediza hill in the city of Tandil, Argentina, in May, 2007. The nature of the project warranted multi-disciplinary works involving topographers, geologists and private enterprises for the design and realisation of the covering material, construction of the anchors, hoisting and the subsequent assembly. Attention was especially given to the structural aspect, for which a typology consisting of an internal steel structure formed by a framework consisting of four grids arranged in two orthogonal planes was adopted. These grid beams transferred the load to the grid column or mast with its vertical axis coinciding with the vertical axis of support. The structure was complemented by cross, longitudinal and horizontal frames, which played a dual role: first, to copy the rock's external geometry and serve as a mould for the outer covering, and second, to comply with the resistance function of transmitting the external loads to the internal structure. A static and dynamic analysis of the resistant structure was performed.
