Abstract: The development of the force method of structural analysis has been hindered by the difficulty of generating a suitable maximal set of independent self-equilibrating stress systems, known as ...

Abstract: In this paper a new guided structural damage identification approach is presented in order to localize and quantify multiple damage cases in different structural systems. The change in the amount of modal strain energy of ...

Abstract: This paper focuses on the introduction of a recently developed meta-heuristic algorithm, which is called colliding bodies optimization (CBO), and its utility for optimal design of truss structure with dynamic constraints. ...

Abstract: To improve the performance of the structure and keep out the resonance phenomenon, some limitations should be imposed on the natural frequency ranges. This paper illustrates the computational performance of enhanced colliding ...

Abstract: The inverse of the stiffness matrices of a large group of repeated and regular structures were previously obtained using graph products. Considering the importance of increasing the speed of the computing process and ...

Abstract: Time–cost trade-off analysis is addressed as an important aspect of any construction project planning and control. Nonexistence of a unique solution makes the time–cost trade-off problems very difficult to tackle. As a ...
