“…The interaction effects are influenced by the soil motions, which produces the kinematic interaction, and the mass from the superstructure, which generates the inertial interaction. Therefore, extensive tests and simulations focused on the SSI effects and seismic behavior of the pile-supported piers or piles in the past decades (Makris et al 1997, Yao et al 2004, Tokimatsu et al 2005, Cubrinovski et al 2006, Chau et al 2009, Motamed and Towhata 2010, Gao et al 2011, Haeri et al 2012, Goit and Saitoh 2014, Durante et al 2015, Wang et al 2015, Durante et al 2016, Su et al 2016, Durante et al 2017). However, there are few experimental studies on the dynamic response and SSI effects of bridges by considering the influences of an actual superstructure.…”

“…In the past, many tests have studied the SSI effects and seismic behavior of pile-supported piers with a concentrated oscillation mass or even neglecting an oscillation mass in different soils (Makris et al 1997, Yao et al 2004, Rollins et al 2005, Tokimatsu et al 2005, Cubrinovski et al 2006, Dungca et al 2006, Chau et al 2009, Motamed and Towhata 2010, Gao et al 2011, Haeri et al 2012, Chang and Hutchinson 2013, Motamed et al 2013, Goit and Saitoh 2014, Durante et al 2015, Wang et al 2015, Durante et al 2016, Su et al 2016, Durante et al 2017, Liu et al 2017, Wang et al 2019). The research work validated experimentally the Winkler foundation model using the displacement transfer function and strain spectrum of a SDOF superstructure supported by a single pile (Makris et al 1997).…”

This research is to assess the influences of the inertial mass from the girder on the dynamic characteristic, dynamic response, and structure-soil interaction of a pile-soil-pier subsystem in a scale-model of a cable-stayed bridge. Therefore, both connection configurations between the pile-soil-pier and girder, including the sliding and fixed connections, were designed to present various inertial mass from the superstructure delivered to the pile-soilpier. The pile-soil-pier supported by a 3×3 pile-group in mixed soil placed in a shear box was tested using shaking tables. The dynamic characteristics, seismic responses, inertial interactions, and pile group effects of the pile-soilpier between the sliding and fixed connections were analyzed under three input motions with different shaking amplitudes. These results showed that more inertial mass from the girder significantly increased the reinforcement strain and bending moment at the column bottom and pile top, displacement at the column top, inertial interaction effects, and pile group effects of the pile-soil-pier due to the sliding connection changing to the fixed connection.The inertial mass increment from the girder noticeably decreased the peak accelerations of the column of the pilesoil-pier when subjected to three input motions with different amplitudes. However, the inertial mass insignificantly affected the accelerations of the pile and free-soil. Therefore, the corresponding kinematic interaction effects were almost unaffected by the inertial mass. Additionally, the evident pile group effects were observed in the sliding and 2 fixed connections between the pile-soil-pier and girder. The numerical model could approximately reproduce the macroscopic seismic responses of the pile-soil-piers with sliding and fixed connections and capture the typical response variations induced by the connection configuration change.

Nonlinear analysis for reinforced concrete members (R.C.) with two types of bars also with unsaturated and saturated soils was used to represent the models. To control the corrosion in the steel bar that used in R.C. member and decrease the cost, the geogrid with steel bar reinforcement are taken in this study to determine the effect of load-deflection and stress-strain relationships. The finite element method is used to model the R.C. member, bars and soil. A three-dimensional finite element model by ABAQUS version 6.9 software program is used to predict the load versus deflection and stress versus strain response with soil. The results for the model in this study are compared with the experimental results from other research, and the results are very good. Therefore, it was concluded that the models developed in this study can accurately capture the behavior and predict the load-carrying capacity of such R.C. members with soil and the maximum stresses with strains. The results show plastic strain values in the R.C. member with saturated soil are larger than their values in unsaturated soil about (54%, 58%, and 55% and 52%) when the geogrid ratios are (without geogrid, 60%, 40% and 20%) respectively, with the same values of stresses.
