  • A three-dimensional model for rain-wind induced vibration of stay cables in cable-stayed bridges

    • Tác giả: Truong, Viet Hung;  Người hướng dẫn: -;  Người tham gia: Vu, Quang Viet; Vu, Quoc Anh (2020)

  • In this paper, the effects of wind velocity according to height above the ground on the rain-wind induced vibration (RWIV) of stay cables are investigated. RWIV of the cable is modeled using the linear theory of cable vibration and the central difference algorithm. The wind speed profile according to height above the ground, which affects both aerodynamic forces acting on the cable and the oscillation of the rivulet on the cable surface, is taken into account in the theoretical formulation. The fourth-order method Runge-Kutta is used for solving the system of differential equation of the cable oscillation. The proposed 3D model of the stay cable is then used to assess the effect...

  • Effect of multiple longitudinal stiffeners on ultimate strength of steel plate girders

    • Tác giả: Truong, Viet Hung;  Người hướng dẫn: -;  Người tham gia: Papazafeiropoulosb, G.; Pham, Van Trung; Vu, Quang Viet (2019)

  • In the present paper, the effect of multiple longitudinal web stiffeners (up to four) located at their optimum location on the ultimate strength of steel plate girders subjected to predominant shear loading, and combined bending and shear loading is investigated by using nonlinear inelastic analysis. Three dimensional (3D) fnite element (FE) models of the steel plate girder are developed and analyzed by using ABAQUS commercial software. The accuracy of the FE models is validated by comparing their results with analogous experimental data. An extensive parametric analysis has been carried out to estimate the influence of specifc geometric parameters on the ultimate strength. It has b...

  • Optimization of steel moment frames with panel-zone design using an adaptive differential evolution

    • Tác giả: Truong, Viet Hung;  Người hướng dẫn: -;  Người tham gia: Ha, Manh Hung; Pham, Hoang Anh; Tran, Duc Hoc (2019)

  • Optimization of steel moment frames has been widely studied in the literature without considering shear deformation of panel-zones which is well-known to decrease the load-carrying capacity and increase the drift of structures. In this paper, a robust method for optimizing steel moment frames is developed in which the panelzone design is considered by using doubler plates. The objective function is the total cost of beams, columns, and panel-zone reinforcement. The strength and serviceability constraints are evaluated by using a direct design method to capture the nonlinear inelastic behaviors of the structure. An adaptive differential evolution algorithm is developed for this optimi...

  • Steel structural design using nonlinear inelastic analysis

    • Tác giả: Truong, Viet Hung;  Người hướng dẫn: -;  Người tham gia: Kim, Seung-Eock (2019)

  • With rapid improvement of computing technology, nonlinear inelastic analysis methods are commonplace and permitted in new design code versions of AISC-LRFD, AASHTO, etc. However, their applications on practical design of steel structures are still very limited due to excessive computational efforts. To overcome this problem, we develop a novel software, named as PAAP3D, in this study. PAAP3D is based on the plastic hinge approach that requires only one or two elements for modeling a frame member so computation time is efficiently reduced. The nonlinear inelastic truss and catenary elements are also implemented in PAAP3D that allows the use of this software for analysis of truss struc...
