steel shear walls, like bracings are a resistance system against wind and earthquake loads, which have more advantages than other systems. this paper is investigating the influence of openings on steel shear walls under increasing static loads. for this purpose, the experiments of other researchers on finite elements method have been checked and after investigating the correctness and precision...

This paper considers the issue related to protection of buildings and structures against seismic influences prevention, exclusion, or reduction hazards. The catastrophic destruction modern «earthquake-resistant» in Turkey Taiwan has shown that existing methods strengthening reinforcing are not perfect require further study. Analysis approaches ensuring resistance showed insulation suppression s...

A semi-Markov model estimating the waiting times and magnitudes of large earthquakes is proposed. The model defines a discrete-time, discrete-state process in which successive state occupancies are governed by the transition probabilities of the Markov process. The stay in any state is described by an integer-valued random variable that depends on the presently occupied state and the state to w...

This paper introduces the application of seismic wave method in earthquake prediction and early estimation. The advantages of the seismic wave method over the traditional earthquake prediction method are demonstrated. An example is presented in this study to show the accuracy and efficiency of using the seismic wave method in predicting a medium-sized earthquake swarm occurred in Wencheng, Zhej...

Rapid prediction of the post-earthquake structural damage to a region is great importance community relief and rescue. Detailed information on buildings in earthquake disaster areas commonly inaccessible aftermath an earthquake. Accurately assessing seismic urban using limited significant. This study proposes design-strength-based method for regional based strength. Only few basic attributes ar...
