The 14th World Conference on Earthquake Engineering
Semi-active control devices have been shown to be more energy efficient than active devices and more effective in reducing seismic structural vibration than passive devices. A new type of semi-active control device, the piezoelectric friction damper has been made in this paper. Piezoelectric actuators used in the dampers can quickly and accurately respond to a voltage signal. They are also effe...

The ability to monitor the health of an instrumented structure, detect damage as it occurs, and issue an early warning during or soon after the earthquake (or some other natural or man made disaster), and before physical inspection is possible, has significant potential benefits in reducing loss of life and injuries, in emergency response, and in recovery following the disaster. The timeliness ...

A self adaptive particle filter method for structural system identification is presented in this paper. Such an adaptive technique that uses statistical methods to adapt the number of particles at each iteration. This method improves the efficiency of state estimation by adapting the size of sample sets during the estimation process through KLD-Sampling. Within this adaptation process the numbe...

This paper presents a computational study assessing the seismic response of rectangular concrete-filled steel tube (RCFT) members and frames to develop a reliability-based performance-based design methodology. A new analysis formulation was derived based on a mixed-finite element approach allowing geometrically and materially nonlinear analysis of RCFT frames under seismic and non-seismic loadi...

The objective of the study presented herein is to access the influence of rupture directivity on the inducement of liquefaction in loose, saturated sand. Rupture directivity is a near fault phenomenon that results in a pronounced double-sided velocity pulse in the strike normal component(s) of motion. Using the Palmgren-Miner fatigue theory, implemented for low cycle fatigue conditions, the num...
