Study on Dynamic Response of Novel Masonry Structures Impacted by Debris Flow
AbstractDebris flow is a very destructive natural disaster. This paper presents a novel masonry structure with strong resistance to debris flow—by using walls that are set with braces and filled with straw bricks. This structure was designed according to the concepts of sustainability. In order to study the dynamic response of this novel masonry structure under debris flow, finite element models of different masonry structures were established by means of LS-DYNA software. The responses of this novel structure and other traditional structures were calculated and compared when the rock of debris flow hits the center of the wall. Results showed that the out-of-plane stiffness of the impacted wall with cross braces was enhanced in this novel structure, leading to an increased resistance to the impact of debris flow more effectively. Furthermore, braces were able to stop rocks in the debris flow and dissipate the corresponding energy through deformation. These braces also improved anti-collapse capabilities, leading to an increase in the safety of people’s lives and properties. This novel structure is a response to national policies and plans, which plays an active role in promoting sustainable development of society. View Full-Text
