Abstract: This paper presents the use of a transfer matrix method to determine the natural frequencies and mode shapes of a multispan, nonuniform beam; and the application of a mode superposition technique to the analysis of dynamic ...

Abstract: In this paper, a new boundary element method for the interaction between frictional bolts and rock mass is presented by formulating the surface frictional forces of the bolts in terms of the displacements of the rock mass. ...

Abstract: A nonlinear finite-element analysis (FEA) model was developed in this paper based on the elastoplastic finite-element theory to analyze the load versus deformation relation of steel beam to concrete-filled steel tubular ...

Abstract: A case was examined in which an underwater shield tunnel was rehabilitated during the construction phase. An unexpected methane eruption resulted in an inrush of water and silt, which damaged the tunnel. Because of this ...

Abstract: A technique for designing torque balancing cam (TBC) systems that are composed of spring-loaded planar cams with translating followers for globoidal cam indexing mechanisms (GCIMs) has been ...

Abstract: The seismic performance of reinforced concrete in a saline soil environment has attracted great attention from the scientific community. This study aims to effectively predict the seismic yield strength of RC at different ...

Abstract: Operational monitoring of pipelines can prevent environmental and economic losses. However, pipeline data have the characteristics of high dimension and nonlinear coupling, which makes it difficult to determine the ...
