...C. S. Tsai; H. C. Su; Yung-Chang Lin, Ph.D. In this paper, a base isolator called a multiple direction optimized-friction pendulum system (Multiple DO-FPS) with numerous sliding interfaces is proposed. To understand the mechanical behavior of the Multiple DO-FPS isolator under multidirectional...

.... This situation, however, also encourages structural engineers to research and develop nonrubber-type isolation systems such as linear motion bearing isolators and friction pendulum systems. It is considered that the nonrubber-type isolation systems can be applied to important industrial facilities, such as LNG...

... gas while the inhabitants escape. This system features easy installation. Constant pressure gas is employed, and is controlled to jet or to stop jetting. The plastic-deformed building is modeled as a two-link inverted pendulum, and the design of the stabilizing controller is based on the sliding mode...
