Cyclic load test
Abstract
"Load testing has been the tool to evaluate a structure whose capacity is investigated due to design/construction flaws, the use of strengthening systems, deterioration, unique design, or change in use.
The current code does not specify the type of load prescribed for load test purposes, but provides the minimum test load magnitude value as a uniformly distributed load. This document provides the description of a procedure that allows the practitioner to design a cyclic load test, in terms of patch load(s) magnitude and position, which would cause the same internal forces developed during a uniformly-distributed load. The procedure consists of a preparatory phase, in which the structural analysis is performed and the “equivalent” load is designed according to the assumed hypotheses, and a test phase, in which the structural behavior is monitored by measuring selected quantities (deflections, rotations and strains) and the load is corrected in real-time according to the actual structural behavior.
The methods allowing the structural assessment through the measurement of strategic response parameters are mainly based on linear structural analysis. The principal unknowns in the evaluation of a structural member are its boundary conditions and the load sharing effect. The problem was split in the real time estimation of two coefficients reflecting span-end fixities and the contribution of other elements in carrying the load, respectively. Engineering judgment is still required to filter automatically generated results: the possibility to obtain values without any physical meaning is always present"--Abstract, page iii.
