The effect of frequency content on the dynamic response of concrete gravity dams is investigated in this paper. Dams are one of the most complex structures to handle when there is dynamic analysis involved. One of the influential parameters on these structureschr('39') seismic response is the frequency content of the earthquakes. An index to represent frequency content, which represents frequen...

Spectral ratios between soft soil and reference rock sites are often used to predict the sedimentary site response to earthquakes. However , their relationship with the genuine site-specific amplification function is often unclear. We compare the soil-to-rock spectral ratios between the stations that are 3.3 km apart with the "genuine" response given by the ratios between the surface and 17 and...

Peak ground acceleration (PGA) prediction is of great significance in the seismic design engineering structures. Machine learning a new method to predict PGA and does have some advantages. To establish explainable models PGA, 3104 sets uphole downhole records collected by KiK-net Japan were used. The feature combinations that make perform best selected through selection. peak bedrock (PBA), pre...

This paper presents a suitable and quick way to choose earthquake records in non-linear dynamic analysis using optimization methods. In addition, these earthquake records are scaled. Therefore, structural responses of three different soil-frame models were examined, the change in maximum displacement of roof was analyzed and the damage index of whole structures was measured. The soil classifica...

Piles and diaphragm wall supported berthing structure on marine soils are loaded laterally from horizontal soil movements generated by dredging. The literature on the adequacy of the finite element method modeling of berthing structure to analyse their behaviour during dredging and under earthquake condition is limited. This paper describes the finite element approach for analysing the lateral ...

Abstract. In the complex medium system of sea area, overlying seawater and surface soft soil have a significant impact on seafloor ground motion, which brings great seismic risk to safety offshore-engineering structures. this paper, four sets typical free-field models are constructed established, comprising land model, model with soil, soil. The dynamic finite-difference method is used carry ou...

the interactive effects of adjacent buildings on their seismic performance are not frequently considered in seismic design. the adjacent buildings, however, are interrelated through the soil during seismic ground motions. the seismic energy is redistributed in the neighboring buildings through multiple structure-soil-structure interactions (sssi). for example, in an area congested with many nea...
