Abstract: The transient dynamic response of the substructures above a removed column is the most direct and realistic to demonstrate the structural performance against progressive collapse. To efficiently obtain the transient dynamic ...

Abstract: Previous research work has found that catenary action can significantly increase structural resistance in addition to flexural capacity under column removal scenarios. However, whether reinforcements in beams can effectively ...

Abstract: Mechanical descriptor systems, i.e., constrained mechanical systems, have many applications in practice. This paper studies the control of mechanical descriptor systems. First, a class of the state ...

Abstract: This paper discusses a theoretical approach to investigate the dependency relationship between the stiffness matrix and the complex eigenvectors in the identification of structural systems for the ...

Abstract: In this paper, a methodology is presented for the identification of the complete mass, damping, and stiffness matrices of a dynamical system using a limited number of time histories of the ...

Abstract: The effect of damping on progressive collapse responses of structures is typically ignored. However, the margin of conservatism resulting from ignoring damping is not well known. Therefore, in this paper, a nonlinear ...

Abstract: Determination of the fracture mode and the initiation mechanism of cracks emanating from preexisting flaws are of great significance for understanding the failure process of rocks. In this research, Brazilian tests were ...

Abstract: To reduce the negative influence of groundwater on foundation pit excavation and the surrounding environment, an analysis of seepage fields has become very important in deep excavation projects. However, the current studies ...

Abstract: Pumping-induced earth fissuring is a typical fluid–solid coupling problem involving fracture evolution. Despite recent advances in the numerical modeling of earth fissures, a holistic approach capable of predicting their ...
