A parametric study of nonlinear seismic response analysis of transmission line structures subjected to earthquake loading is studied in this paper. The transmission lines are modeled by cable element which accounts for the nonlinearity of the cable based on a real project. Nonuniform ground motions are generated using a stochastic approach based on random vibration analysis. The effects of mult...

Abstract. Earthquake site response is an essential part of seismic hazard assessment, especially in densely populated areas. The shallow geology the Netherlands consists a very heterogeneous soft sediment cover, which has strong effect on amplitude ground shaking. Even though low- to moderate-seismicity area, risk cannot be neglected, particular, because induced earthquakes occur. aim this stud...

This study, tries to suggest a design method based on displacement using finite difference numerical modeling in reinforcing soil retaining wall with steel strip. In this case, dynamic loading characteristics such as duration, frequency, peak ground acceleration, geometrical characteristics of reinforced soil structure and type of the site are considered to correct the pseudo static method and ...

iran is an active seismic region. earthquake damage is commonly controlled by three interacting factors including source and path characteristics, local geological and geotechnical conditions and type of the structures. obviously, all of this would require analysis and presentation of a large amount of geological, seismological and geotechnical data. in this paper, nonlinear geotechnical seismi...

An integrated seismic monitoring system with a total of 55 channels of accelerometers is now operating at and in the nearby free-field site of the 20-story steel-framed Atwood Building, in highly seismic Anchorage, Alaska. The building has a single-story basement and a reinforced-concrete foundation without piles. The monitoring system comprises a 32-channel structural and a 21channel site arra...

This study aims to develop seismic fragility curves for a typical pile-supported wharf. Fragility curve is one of the popular tools in seismic performance evaluation of a structure. The software FLAC2D was used to simulate the seismic performance of the wharf structure. Using eight time history records, occurred in past, as seismic loading, incremental dynamic analysis (IDA) was applied for sei...

Design of municipal solid waste (MSW) landfills requires a considerable attention due to the undesirable environmental and socio-economical impact of a potential failure. Furthermore, recent research and engineering practice experience in developed countries characterized by high seismicity, like U.S.A and Japan, has shown that MSW landfills are vulnerable to the seismic threat. Despite the viv...
