Abstract

With the development of civil engineering, the U-shaped beam has been widely applied in practical engineering. In general, it is composed of concrete and steel and compared with mechanical analysis, little research has been carried on the inversion analysis of elastic parameter of U-shaped beam. With degraded solid element theory, the shell element is deduced and the displacement function is obtained. The necessary observation revision equation and Kalman regenerative matrix are derived. The stochastic filtering inversion analysis steps of elastic parameter of the U-shaped beam are presented and the analytical procedure is compiled. Through analysis of a classic example, some important conclusions about stochastic filtering inversion analysis of elastic parameter of U-shaped beam are obtained.
