A continuation method for bifurcation tracking is presented based on the proposed optimization problem formulation which is designed to locate the bifurcation periodic solution. The bifurcation detection problem is formulated as a constrained optimization problem. The nonlinear constraints of the optimization problem are imposed on the shooting function and bifurcation conditions derived from the Floquet theory whereas the objective function associated with the pseudo-arclength correlation equation is devised to solution continuation. The proposed optimization formulation is integrated with the prediction–correction strategy to achieve bifurcation tracking. Two numerical examples about the Jeffcott rotor and the nonlinear tuned vibration absorber are illustrated to validate the effectiveness of the proposed methodology. Numerical results have demonstrated that the proposed method offers a convenient scheme to follow bifurcation periodic solution.

This paper presents a metaheuristic-based optimization methodology for optimum design of axially symmetric cylindrical reinforced concrete walls that are a type of thin shells. In the methodology, recently proposed metaheuristic algorithm called Jaya algorithm is conducted with well-known method called flexibility theory. The thickness of the wall is defined as a design variable of the optimization problem and the total material cost, including concrete and steel bars, is the objective function. Reinforced concrete design is done according to rules of regulation ACI 318-Building code requirements for structural concrete. The proposed method is performed for different numerical cases of design constants to investigate effects of the wall height, dome height and thickness, and specific weight of stored liquid on optimum parameters for different support conditions. The investigation includes the optimum design of axially symmetric cylindrical reinforced concrete walls with and without domes. Analyzes were done for a total of 13,650 different situations, and various expressions such as linear, parabolic, and exponential were also proposed to assist engineers in their practical applications. According to the results of the analysis, it has been revealed that each investigated case has an effect on the optimum results and the proposed equations are successful in finding values quite close to the optimum design.

Particle tuned mass dampers (PTMDs) have attracted recent attention for reducing seismic demands on large structures. Yet, research on the control performance of PTMDs for soil-structure interaction (SSI) systems under earthquake excitations is non-existent. This paper presents a comprehensive investigation on the effectiveness of PTMD devices for pile-supported multistory frames through shaking table tests and simulations with validated numerical models. Particle damping effectiveness is analyzed through comparisons with systems lacking external damping. The test results show that the mitigation effects of PTMDs on the maximum structural accelerations and displacements decrease when SSI effects are present and that particle damping improves control performance of conventional TMDs. Detailed finite element models of the tested specimens are also constructed-including SSI effects-and validated initially against the test data. In these models, the soil nonlinearities are considered using a bounding surface plasticity model, and the PTMD devices are simplified to an equivalent single-particle damper using an analytical model. The validated numerical models can be used in further parametric studies involving optimal PTMD design and deployment within a performance-based seismic engineering framework.
