Do not leave until the shaking is over. Walk out carefully watching for anything that could fall during the aftershocks. If you are near the shore, drop, cover, and hold on until the shaking stops. If severe shaking lasts 20 seconds or more, immediately evacuate to high ground as a tsunami might have been generated by the earthquake.
Dec 02, 2013 As part of a multiyear Technology Innovation research project, BPA partnered with the Multidisciplinary Center for Earthquake Engineering Research at State University of New York at Buffalo, to test the performance of base isolation technology and then install it on an operational unit. The standard for testing the seismic performance of equipment is to model it on a shake table.
What is EDAT?Much of the Earth’s population lives under threat of geologic hazards, including shaking, landslides, liquefaction, and tsunami. The USGS and USAID Earthquake Disaster Assistance Team (EDAT) strives to assist foreign partners, upon their request, with seismic hazard identification and monitoring and to support them as they take the lead in mitigating these hazards
(CGS 2008). This indicates that a relatively low level of seismic ground shaking would be anticipated in the project area. However, most of the project elements would be constructed in unstable, unconsolidated riverine sediments in areas where a high water table is present. Thus, there is a potential for liquefaction to occur.
An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.
performance, and testing key equipment with shake table tests to provide fragility functions for the loss models. The outcomes from both projects will inform planning for the protection of laboratory contents and provide an analytic data set for future efforts in performance assessment and loss modeling.
A building developed by Wuhan Shimao Group in Wuhan, China, is a high-rise residence with 56 stories near the Yangtze River. The building is a reinforced concrete structure, featuring with a nonregular T-type plane and a height 179.6 m, which is out of the restrictions specified by the China Technical Specification for Concrete Structures of Tall Building (JGJ3-2010). To investigate its ...
A shake table is a special type of table that engineers use to simulate an earthquake on model buildings. One very large shake table is at the Pacific Earthquake Engineering Research Center (PEER) at the Department of Civil and Environmental Engineering, University of California, Irvine.
Earthquake is one of the major natural disasters. Every year it causes a huge loss of life and property all around the world. Proper strategies and awareness about disaster management is the need of the hour. This will protect us from the losses and help to cope up with these hazards.
The input motion was the Canoga Park Topanga Canyon record of the 1994 Northridge, California earthquake, Mw 6.7. The house was subjected to eight levels of seismic shaking, beginning at 25% of the recorded ground acceleration and increasing at 25% increments. The house survived 0.82g, twice the acceleration of the Canoga Park record.
This project subjected three one-third scale single columns to Sylmar earthquake with gradually increasing PGA using one of the shake tables at the University of Nevada, Reno and the mass-rig setup. After each test, the column was repaired rapidly, using CFRP wrapping, and retested to evaluate the emergency repair performance.

Feb 28, 2007 Civil engineering is the application of engineering principles to build large structures like roads, dams, or bridges. Usually civil engineering projects are for the public good, and provide an essential function. For example, bridges provide an essential corridor for traffic in parts of the world where large bodies of water separate an urban area.
The 6 DOF shaking simulator with its control system was, at that time, unique. It was manufactured in the USA with the exception of the steel table as well as some minor items of the facility that were constructed in Athens. The weight of the reinforced concrete reaction mass amounts to 25MN.
The project intends to provide community ... Introduction Earthquake civil engineering is concerned with the design and analysis of structures to withstand hazardous earthquakes at specific locations and steel seismic design is one of the main ... because soft soils amplify ground shaking . Table 3- Depicts the five different soil types
The model box used in this model test is a rigid model box welded by angle steel, channel steel, and steel plate. The model box is 2.0 m long, 2.0 m wide and 1.5 m high, as shown in Figure 2.
Jan 12, 2014 The location on the Earth‟ s surface directly above the focus is called the epicenter. The study of seismic waves and earthquakes is called seismology, which is a branch of geophysics. Two types of seismic waves are generated at the earthquake focus: 1. Body waves spread outward from the focus in all directions. 2.
