Structural vibration control is one of the most important features in structural engineering. Real-time information about seismic resultant forces is required for deciding module of intelligent control systems. Evaluation of lateral forces during an earthquake is a complicated problem considering uncertainties of gravity loads amount and distribution and earthquake characteristics. An artificia...

Probabilistic characteristics of seismic responses of the Partially Restrained connection rotation (PRCR) and panel zone deformation (PZD) installed in older steel moment frames were investigated in accordance with statistical inference in decision-making process. The 4, 6 and 8 story older steel moment frames with clip angle and T-stub connections were designed and analyzed using 2%/50yrs grou...

Earthquake mainly produces Pand Swave at the point of occurrence. Mining site that mines the geological material from earth often makes the quarry blasts on the surface of earth to accelerate the mining process instead of drilling. This mining blast also causes the same wave as the earthquake. It is very difficult to differentiate between two of them as the characteristics of waves produced by ...

The Schumann resonance phenomenon has been monitored at Nakatsugawa (near Nagoya) in Japan since the beginning of 1999, and due to the occurance of a severe earthquake (so-called Chi-chi earthquake) on 21 September 1999 in Taiwan we have examined our Schumann resonance data at Nakatsugawa during the entire year of 1999. We have found a very anomalous effect in the Schumann resonance, possibly a...

BACKGROUND The aim of this study was to compare retrospectively the characteristics of chest injuries and frequencies of other, concurrent injuries in patients after earthquakes of different seismic intensity. METHODS We compared the cause, type, and body location of chest injuries as well as the frequencies of other, concurrent injuries in patients admitted to our hospital after the Wenchuan...

A strong earthquake-induced hazard has obvious long-term and spatial heterogeneity, which will result in continuous social economic losses. Measuring the socioeconomic development level of disaster area is great significance for reconstruction after an earthquake. First, kernel density estimation (KDE) used to analyze effects 10 extremely earthquake-stricken areas Wenchuan earthquake this paper...
