...RECENT DEVELOPMENTS IN THE UNDERSTANDING OF EARTHQUAKE SITE RESPONSE AND ASSOCIATED SEISMIC CODE IMPLEMENTATION Ricardo Dobry1 and Susumu Iai 2 ABSTRACT The paper focuses on the compelling evidence on site amplification of earthquake motions accumulated in the last fifteen years or so, which...

... ABSTRACT: The emphasis in traditional seismic design codes and guidelines for structures in the United States has been on collapse prevention, and on structural analyses which empirically reduce elastic earthquake response forces to reflect inelastic behavior of structural elements...

... SEISMIC MICRO-ZONATION OF DELHI Vijay Gupta1, Harry G. Poulos2, Stuart G. Reid3 ABSTRACT This paper describes the results of a study of the seismic micro-zonation of Delhi. It presents a summary of the study with respect to geological characteristics, geotechnical investigation, earthquake climate...

... Tests were used in the analysis for determining cyclic strength of the soil. SeedÕs Simplified Procedure was employed for evaluation of liquefaction potential. Based on the analysis carried out for different magnitudes of earthquake, it was concluded that the top soil is susceptible to liquefaction due...

... ABSTRACT: On 12 April 1998, the strongest earthquake in the last century with an epicentre in Slovenia shook low a populated area in the Alps (The upper Soca Territory) of NW Slovenia. The earthquake of a local magnitude of 5,6 (MwA=6,0) caused no loss of life, although a lot of damage...

... equilibrium state, even a slight earthquake may trigger it to destabilize. An intensive earthquake may directly cause a whole slope to fail. Kangding City is located in the intersection of three famous active seismic belts and thus with frequent earthquake activity. Many earthquakes occurred there in the past...

... Evaluation Earthquake (SEE) and Functional Evaluation Earthquake (FEE) are defined. The SEE event has only a small probability of occurring during the useful life of the bridge. The FEE is intended to represent an event that has a reasonable probability of not being exceeded during the life of the bridge...

... ABSTRACT: The conventional Newmark model is widely used for the estimation of permanent deformations of slopes during earthquakes. However, the calculation procedure for permanent displacements in the Newmark model is based on a distinct and fixed slip surface. In other words, the Newmark...

... THE ROLE OF EARTHQUAKE WARNING SYSTEMS M. Bahrekazemi1 & A. Bodare2 ABSTRACT The fact that each year thousands of people in seismically active parts of the world are killed or injured due to major earthquakes urges for continuous efforts in order to lessen the size of the catastrophe. Technical...

... facilities. Although the importance of monitoring was recognized in the field of lifeline earthquake engineering, there are few monitoring systems to detect the occurrence of liquefaction. Tokyo gas has conducted the monitoring of liquefaction by using water pressure meters. This method needs much money...

... ABSTRACT: On 29/10/1989, Tipaza"s region situated in the west of Algiers, was vibrate shaken by the Chenoua earthquake. The distance between the centre of this earthquake and Algiers, the capital (90 km), wasn"t a to make a damages for the constructions (Casbah, Bab El Oued, Hamma, Tagara...

Spectral characteristics during earthquakes at most sites show fairly good correlation with geological data and H/V spectrum for microtremor records. INTRODUCTION The Nobi plain in Tokai district...

... seismicity (RIS) are cited by Gupta (1992). The induced earthquakes range from shallow, less than 1 – 2 km focal depth, to moderate crustal depths of 10 – 12 km. A large majority of events appear to fall within the 4 – 6 km depth range, which would place them within the crystalline basement rocks at levels...

... ABSTRACT: Fill dams may be classified into modern dams constructed based on design standards and small earth dams built based on empirical technology. This paper describes survey and analysis of earthquake damage to fill-type dams. After 1953, design standards of fill-type dam based on modern...
