Abstract: In the ground structure strength test, it is necessary to transform the original theoretical load into the testing implementa-tion load, which decides the authenticity and validity of the test. The traditional load transacting method is based on load equivalent, then compares the numerical analysis result. It is open-loop control method, the efficiency and accuracy are often drop sharply when encountering complex structures and loads. It puts forward a kind of testing load transacting method based on assessment target equivalent. The numerical simulation analysis is combined with the load transacting process. A closed structure of load optimization, testing state simulated analysis and assessment target evaluation is es-tablished. Structural objective response is taken as evaluation criterion and optimization object. Using sensitivity analysis, genetic algorithm, It greatly improve the efficiency and accuracy of load transacting. On this basis, developing the load transacting software based on the MATLAB GUI platform. It implements a variety of functions modularized, such as the sensitivity analysis, load-response matrix calculate, load optimization design. Then apply this method to the elevator struc-ture load transacting process, realizing the error of assessment target to be controlled critically in load transacting process.
