Sections of earth scientists firmly believed it had triggered the trembler. Artificial reservoirs are created for flood control, irrigation and power generation. The Koyna ground motion is relatively more severe, compared to California earthquakes of similar intensity, on concrete gravity dams. Study on the Heterogeneity of Concrete and Its Failure Behavior Using the Equivalent Probabilistic Model. Karan Bose, Managing Director, Hula Global1. Earthquake Engineering and Engineering Vibration. Experience cleaner site with zero ads and faster load times. Application of NLFM Models to Predict Cracking in Concrete Gravity Dams. Numerical simulation of reinforcement strengthening for high‐arch dams to resist strong earthquakes. Koyna is best suited for research to unravel the phenomenon, according to the International Continental Drilling Programme, a group of 30 international and 50 Indian scientists, who first met in 2011 at National Geophysical Research Institute (NGRI). The implicit Newmark- β method is used in the incremental dynamic analysis for time stepping, which is unconditionally stable. Gupta and a large group of seismologists from NGRI who have been working on the area have developed a model that they claim has been tested over the past few years, and found to be reasonably accurate in terms of time and locate of quakes with 4+ magnitude. THE Koyna earthquake of December 11, 1967, killed about 200 people and injured a few thousand. A combined XFEM–damage mechanics approach for concrete crack propagation. Questions have been raised about the huge costs and also the practicality in the Indian context, where the threat and chances of a massive 7+ plus quake are more likely in the Himalayan belt. These include Kariba on the Zambia-Zimbabwe border (1963), Hsingfenking in China (1961), Kematsa in Greece (1966) and Koyna, which was the biggest, in 1967. A novel procedure for determination of hydrodynamic pressure along upstream face of dams due to earthquakes. Fifty years hence, scientists think they are close to digging up clinching evidence. The biggest, of course, was the 6.3 magnitude quake of 1967. Globally, there have been about 120 cases of triggered earthquakes.

Working off-campus? is responsible for causing a significant part of the critical tensile stresses; attention should therefore be given to developing lightweight supporting systems. And it left seismologists shaken. 4, which is scaled to have 0.34 g spectral acceleration in the stream direction, is used as seismic excitation. You can also download our Android App or IOS App. See %g in the Earthquake Glossary. There are several cases, e.g. The earthquake activity, which began in 1962, has so far seen more than 200 episodes of 4+ magnitude, and 22 episodes of 5+ magnitude. Please check your email for instructions on resetting your password. Numerical Simulation of Reinforcement Strengthening for High–Arch Dams to Resist Strong Earthquakes. Nonlinear seismic response of concrete gravity dams using damage mechanics including dam-reservoir interaction. 28: EL-CENTRO COMP S00E: Data (ground accelerations) N = 2689. dt = 0.02 sec. First of all, the simplest way to scale earthquake acceleration is to divide every data of acceleration record by, for example 0.1/PGA in which PGA is the peak ground acceleration of desired quake. Enter your email address below and we will send you your username, If the address matches an existing account you will receive an email with instructions to retrieve your username, I have read and accept the Wiley Online Library Terms and Conditions of Use. By continuously monitoring the activity around the reservoir, it is possible to predict an earthquake ahead of time.

Vibration-based damage detection of concrete gravity dam monolith via wavelet transform. At first, these accelerograms are scaled to PGA=0.07 g, which was derived by the ET method, then the Koyna dam is analyzed by these accelerograms.

The results of displacement and tensile stress from the average of these earthquakes are illustrated in Figure 18 . And it left seismologists shaken. Number of times cited according to CrossRef: Earthquake Engineering for Concrete Dams. . In contrast, the chances of a Koyna type big earthquake occurring in peninsular India are very rare, maybe one in hundred years. Study on the Heterogeneity of Concrete and its Failure Behavior Using the Equivalent Probabilistic Model. Phase-field model for brittle fracture. An experimental investigation into earthquake‐induced failure of medium to low height concrete gravity dams. Non‐linear behavior of mass concrete in three‐dimensional problems using a smeared crack approach. By- Arun Bapat The Koyna earthquake in Maharashtra took a death toll of about 200 people on this day 50 years ago. Seismic response of concrete gravity dams under near field and far field ground motions. Significant tensile stresses must have developed in Koyna Dam during the Koyna earthquake and similar stresses would have developed even in typical gravity dam sections. Seismologists argue that large reservoirs can hold more than 1 trillion litres of water that can crack and fissure the insides of the surrounding earth when the water levels inside rise and fall.

The zone factor for the seismic zone IV is 0.24 that implies a design PGA or zero period acceleration of 0.24 g in response spectra for Maximum Considered Earthquake (MCE). Earth scientist and seismologist Harsh K Gupta, one of the foremost proponents of RIS, backs his nearly half a century of research to claim that Koyna is the best spot in the world to understand how earthquakes occur. : Estimation of PGA and SA for South India G-R method.
