Steel Plate Shear Wall (SPSW) is made from thin steel plate which in turn are framed by the beams and columns of structural system. In recent year they are proved to be very effective and economical for resisting lateral loads such as earthquake and wind loads.The present work targets to study the behaviour of single frame SPSW with different plate thicknesses, rigid and non-rigid frame members...

in this work the general aspect and the behavior of a simplified theoretical model for studying mass isolated systems are investigated. the model is in the form of a dual mass model in a single storey arrangement. to find damping ratio and natural frequency of the system, non-classical eigen analysis has been performed on the model. later, time integration analyses subjected to different earthq...

In this research, we have developed the data driven computational walking model to overcome the problem with traditional kinematics based model. Our model is adaptable and can adjust the parameter morphological similar to human. The human walk is a combination of different discrete sub-phases with their continuous dynamics. Any system which exhibits the discrete switching logic and continuous d...

We analyze the nonlinear elliptic problem ∆u = λf(x) (1+u)2 on a bounded domain Ω of R with Dirichlet boundary conditions. This equation models a simple electrostatic Micro-Electromechanical System (MEMS) device consisting of a thin dielectric elastic membrane with boundary supported at 0 above a rigid ground plate located at −1. When a voltage –represented here by λ– is applied, the membrane d...

Since the 1960s civilian technology demonstration programs in the US Departments of Transportation and Commerce have manifested a pattern in their initiation, content, and outcomes. Programs are episodic, with long periods of relative inactivity occasionally interrupted by brief periods of budgetary largesse. Program content often emphasizes information and automation technologies and system in...

PURPOSE Research verifying the ability of various devices to reduce the forces required for transfers is virtually nonexistent. Therefore, we compared the push forces required to move passive seated subjects across a horizontal surface when four different methods were employed. SUBJECTS 10 men and 14 women (weight 49.1-96.8 kg) served as subjects. METHODS AND MATERIALS Passive subjects were...

In this paper, the successive overrelaxation iteration and the variation of parameters formula are used to discuss the stability of linear and nonlinear Volterra integrodifferential equations. Some sufficient conditions are obtained, such that the trivial solution of the Volterra integrodifferential equations is asymptotically stable; these stability conditions are given directly from the coeff...
