The prototype hybrid high-rise structure is special for its dual structural systems, so a 1/50 shaking table model was tested by the State Key Laboratory of Disaster Reduction in Civil Engineering of Tongji University to study its seismic behaviors. Then numerical models were made by 3D finite element analysis software, named MIDAS. The comparison of the analytical and experimental results veri...

Friction is a nonlinear phenomenon which has destructive effects on performance of control systems. To obviate these effects, friction compensation is an effectual solution. In this paper, an adaptive technique is proposed in order to eliminate limit cycles as one of the undesired behaviors due to presence of friction in control systems which happen frequently. The proposed approach works for n...

Unfortunately, the major group of the systems in industry has nonlinear behavior and control of such processes with conventional control approaches with fixed parameters causes problems and suboptimal or unstable control results. An adaptive control is one way to how we can cope with nonlinearity of the system. This contribution compares classic adaptive control and its modification with Wiener...

in this article, we tried to emphasis in how the range of torsionally stiff and flexible single story buildings works. the designed base was according to provisions of the canadian standard, 2005 nbcc. the behavior of nonlinear dynamic time history of eight building models subjected to seven horizontal bi-directional ground motions compatible with design spectra are investigated. these models c...

the aim of the present study was to investigate and compare the effects of twokinds of motivational and instructional self–talk on the performance of static anddynamic balance tasks in the elderly. for this purpose, 45 old subjects agedbetween 60 and 70 from qom province participated in this study. static balancetask (stand on one leg) and dynamic balance task (sebt test) were instructed withno...

A review of previous studies shows that there are two general views on how to determine demand in structures through incremental nonlinear static analysis. In the first view, multi-modal methods are used to determine demand in structures. In this view, the applied load pattern is applied to the structure according to the shape of each vibration mode, assuming that the structure deformation foll...

In this paper the damage location in beam like-structure is determined using static and dynamic data obtained using finite volume method. The change of static and dynamic displacement due to damage is used to establish an indicator for determining the damage location. In order to assess the robustness of the proposed method for structural damage detection, three test examples including a static...
