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 ...

Computer software for academic research (e.g. DRAIN2D) is often deficient in Graphical User Interface (GUI) and commercial software doesn’t open GUI’s framework to the user. The advantage of GUI is so evident and the requirements of GUI always exist. Thus, there exist sufficient reasons to research on the GUI’s framework. This article introduces that how to build an extensible and flexible GUI ...

The concept of plate tectonics is generally accepted in earth science and seismology. The surface of the earth is divided into rigid tectonic plates that move on the earth surface at extremely slow speed. The islands of Japan sit on the North American and Eurasian plates. The Pacific plate moves westward and the Philippines plate moves to northwest direction; both plates sink under the islands ...

Ground Motion Definition Earthquake events and realized earthquake ground motions are extremely uncertain even with the present knowledge, and it is not easy to predict forthcoming events precisely both in time and frequency (Anderson and Bertero, 1987; Takewaki et al., 1991; 2013; 2011a; Conte et al., 1992; Ariga et al., 2006; Minami et al., 2013; Çelebi et al., 2014). For example, recently re...

Substantial research has been conducted to advance structural control as a means of mitigating the dynamic response of civil structures. Recently, the structural engineering field has begun exploring low-cost wireless sensors for structural monitoring applications. Wireless sensors can be employed to reduce the labor and costs associated with installing extensive lengths of coaxial wires in tod...

Ductility demand during an earthquake has long been known to be a good measure of structural damage in buildings during earthquakes. For design purposes it is considered a priori according to some rules that may or may not apply to each building. Such ductility parameters are mostly based on the response of a single degree of freedom system to ground motions. However, it has been probed that th...

This paper presents a study to statistically characterize the joint earthquake-snow hazard and subsequently develop maximum inter-story drift fragility curves for a series of archetype woodframe structures. Of particular focus are structures built in heavy-snow regions where seismic design may govern (and hence the roof snow load contributes additional seismic mass). While load standards such a...

The 1994 Northridge, California, earthquake is the first earthquake for which we have all of the data sets needed to conduct a rigorous regional analysis of seismic slope instability. These data sets include (1) a comprehensive inventory of triggered landslides, (2) about 200 strong-motion records of the mainshock, (3) 1:24,000-scale geologic mapping of the region, (4) extensive data on enginee...
