Cultural heritage buildings were typically built without considering seismic action and are therefore potentially susceptible to earthquake damage. The performance states and protection objectives developed for ordinary buildings are not directly applicable since they do not address the cultural importance of the heritage buildings. This paper proposes a seismic conservation strategy for cultur...

This study discusses how tsunamis form from earthquakes and how remote-sensing technologies can be used to detect tsunami scales. According to the conventional theory, tsunamis are formed by the vertical deformation of the seafloor during undersea earthquakes. However, our recent studies contradict to the established theory. We will first show evidence—based on GPS displacement measurements, sa...

Based on our field investigations of landslide hazards in the Wenchuan earthquake, some findings can be reported: (1) the multi-aspect terrain facing empty isolated mountains and thin ridges reacted intensely to the earthquake and was seriously damaged; (2) the slope angles of most landslides was larger than 45°. Considering the above disaster phenomena, the reasons are analyzed based on shakin...

Performance-based seismic design (PBSD) method has been widely recognized in recent years, it can be used for the future structural design. And the direct displacement-based design method (DDBD) is one of the most effective ways to implement the performance-based seismic design (PBSD) theory in current. In this paper, aiming to the composite frame consisting of composite beams and continuous co...

In many businesses, including hydrocarbon industries, reducing cost is of high priority. Although hydrocarbon industries appear able to afford the expensive computing infrastructure and software packages used to process seismic data in the search for hydrocarbon traps, it is always imperative to find ways to minimize cost. Seismic processing costs can be significantly reduced by using inexpensi...

The present work is aimed at assessing the impact of strong column-weak beam (SCWB) criterion on seismic performance of optimally designed steel moment frames. To this end, different SCWB ratios are considered for steel special moment resisting frame (SMRF) structures and performance-based design optimization process is implemented with the aid of an efficient metaheuristic. The seismic collaps...

Abstract Natural disasters may lead to failure of critical assets part railway systems. Slope often results in major economic consequences. Due the importance that railways systems have, it is pertinent ensure good performance and long‐term. The objective present research propose tools allow obtaining probability soil slopes under a seismic event by employing surrogate models ease computational...
