Test Loading of Structures with a Suspect Resistance

The reliability of load-bearing structures is normally secured through codes, a competent structural design and proper execution inspection. Alternatively, the can be obtained via skilled test loading, which feasible technique both in construction new verification existing ones. Although current codes lack instructions for they are, however, used special cases; example, when doubtful due to defect, or structure suspected have especially high resistance variability. Test loading involves significant research questions that need addressed, including: What load comparison with expected maximum service time characteristic load? How instantaneous compared actual long-term service-time Does harm structure, what target calculation? In this paper, we approach these from theoretical point view propose how suitable chosen practice using an approximate precise approach.
