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...

The use of “ductile seismic frames,” whose proper seismic behavior largely depends upon construction details and specific design rules, may do not always lead to effective seismic resistant structures, as dramatically denounced by the famous Chinese artist Ai Weiwei in his artwork Straight. The artwork (96 t of undulating metal bars that were salvaged from schools destroyed by the 2008 Sichuan,...

The use of machine learning across many fields has seen a rise in recent years, from life and physical sciences to finance and athletics. Within the physical sciences, it is just starting to see some implementation in the field of Earthquake Engineering. The objective of this paper is to implement machine learning to Earthquake Engineering data to create more literature in the field. In particu...

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...
