Restored Marble Epistyles Under Bending: A Combined Experimental and Numerical Study
A combined experimental and numerical study of restored marble epistyles is presented. The epistyles are symmetrically fractured in two identical pieces normally to the longitudinal axis of the member. Restoration is achieved using bolted titanium bars placed in successive horizontal planes. The experimental protocol included two types of tests with specimens simulating all the geometrical details of typical epistyles of the Parthenon Temple under an 1:3 scale: a) Bending under dead weight (the weight of superimposed structural elements) in an effort to study the actual loading conditions in case the restored element is placed in its original position, and b) 10-point bending with the aid of a stiff hydraulic frame aiming to check the limits within which the restored elements behave as intact members. The results were used for the calibration and validation of a numerical model in order to study the parameters influencing the behavior of the epistyle. The analysis enlightened interesting points concerning the variation of critical mechanical quantities within the volume of the restored epistyle. Based on these results, crucial points are discussed related to the minimization of the intervention on the authentic architectural member (according to Venice charter).
