Model Test And Finite Beam Element Solution Of Cyclic Lateral Characteristics Of Piles In Sloping Ground, Wen-Zhe Peng, Ming-Hua Zhao, Chao-Wei Yang, Heng Zhao
Rock and Soil Mechanics
To reveal the cyclic lateral characteristics of piles in sloping ground under the combined influence of slope effect and cyclic weakening effect, one-way cyclic lateral loading tests with different cycle numbers, load amplitudes and slope angles were carried out, and corresponding lateral static loading tests were conducted as a comparison. The variation trends of pile head deflection, bending moment and subgrade reaction were revealed. Then, the element stiffness matrix was improved by considering the second-order effect and pile-soil interaction to develop the finite beam element solution. Finally, the theoretical predicted curves were compared with measured curves and results calculated by …

Simplified Analytical Solution For Horizontal Seismic Response Of Single Piles To Vertically Incident S Waves, Chang-Jie Zheng, Yi-Qin Cui, Chen Wu, Tong Luo, Lu-Bao Luan
Rock and Soil Mechanics
Based on the continuous medium model and the pile-soil interaction, the horizontal seismic response of a single pile subjected to vertically propagating S waves was investigated by regarding the single pile as a one-dimensional linearly elastic beam. The time-harmonic displacement of bedrock was introduced as the vertically propagating S waves, and the horizontal dynamic impedance function of the soil was derived by the governing equations of the plane strain model. Analytical solutions for the seismic response of the single pile subjected to vertically propagating S waves were obtained by subsuming soil impedance into the governing equation of the single pile …
