Empirical methods are the means by which scientists gather information about the world in order to develop theories. These include experiment, disclosure for peer review, and other ways in which theories are assessed by scientists. The term quasi-empirical methods evolved to describe aspects of the scientific method which are not amenable to disproof by experiment. These are now widely recognized to constitute much of what is loosely called 'scientific consensus', as some theories are not amenable to direct experimental invalidation, or indeed controlled experiment.
The term "empiricalmethods" refers to experiment, disclosure of apparatus for reproduction of experiments, and other ways in which science is validated by scientists.
Empiricalmethods are studied extensively in the philosophy of science but cannot be used directly in fields whose hypotheses are not invalidated by real experiment (mathematics, theology, ideology).
In these fields, the prefix 'quasi' came to denote methods that are "almost" or "socially approximate" an ideal of truly empiricalmethods.
Empiricalmethods assess the stability of structures by the use of past practices to predict future behaviour based upon factors most critical towards the design.
Empirical derivations have gained acceptance over the last fifteen years largely due to their predictive capability since conventional methods of assessment have the difficulty of identifying the jointed mature of the rock material, assigning properties thereto and establishing input parameters for subsequent numerical evaluation.
The methods of design are based upon a strong analytical foundation coupled with extensive field observations to arrive at a calibrated empirical approach towards the solution to a given problem.
