In the tradition theatrical stage scenery sets, many heave instruments devices and Manual body Labor were needed. If the stage scenery set is moved, the manual scenery Sets are needed to re installed. That is very inconvenience. In this paper, we propose a Global and Local (GL) new electromagnetic (EM) industrial and art scenery design model. Also, we use GL EM modeling to simulate the GL EM sc...
The modern techniques for digitization of strong-motion accelerograms and subsequent data processing were first developed in the late 1960s and early 1970s, at which time the only available digitization technology was semi-automatic hand digitization. Following the development of image processing technologies in the early 1970s, an automatic digitization and data processing system, driven by a ...
ONE OF the most important problems in the field of earthquake engineering deals with the dynamics of structures. Any building is an elastic system. As such, its deflections (stresses) during an earthquake may depend on its own dynamical characteristics as well as on the nature of the ground motion. An ordinary building is a relatively complicated dynamic system, usually of many degrees of freed...
After the occurrence of an earthquake, the issues such as making decision promptly on building safety, making possibility to keep on utilizing from a building, locating the ruined place and the rate of the destruction is crucial. Today a new technique is the application of evolutionary artificial neural network models based on artificial intelligence, which is widely used in various scientific ...
Many liquid storage tanks around the world have affected by earthquakes. This structure can store dangerous chemical liquids. Hence dynamic behavior of ground supported rectangular storage tanks is very important due to their applications in industrial facilities. In current research, the seismic behavior of two water storage rectangular concrete tanks is examined. For this purpose, these tanks...
This paper uses Artificial Neural Network (ANN) models to compute structural response of a structural system by training the model for a particular earthquake. Here, the earthquakes in India viz. at Chamoli and Uttarkashi ground motion data have been considered for the analysis. The neural network is first trained here for a single real earthquake data on a single degree of freedom structural s...
Dynamic rupture process of earthquake fault and its near-field strong ground motions are simulated by time-space-decoupled, explicit finite element method with multi-transmitting formula (MTF) of artificial boundary in this paper. This decoupled, explicit method has advantage to easily incorporate into time-step simulation of dynamic rupture process on earthquake fault, as well as wave motions....
Understanding strong ground motions in the near-fault areas is important for seismic risk assessment in densely populated areas. In the past, lack of information on strong ground motion for large and moderate earthquakes led to the use of mainly far field large and moderate earthquake records in equations for calculation of the strong ground motion parameters. In this article, we collected and ...
