【Abstract】 A method of dynamic test for masonry structures using the low order modal parameters is presented. Differential evolution is utilized to achieve the identification of the storey stiffness of masonry structures. The strengths of masonry structure are obtained through the relevance between the storey stiffness and axial compressive strength. The numerical simulation shows the method is precise,simple and efficient. The method may become a new way of masonry structure test.更多还原
