Comparisons between the measured and predicted results affirm the validity of the proposed model. Plain Language Summary: Understanding the freezing and thawing behavior of soils is critical for construction in cold regions. The soil freezing characteristic curve (SFCC), which describes the relationship ...
In this study, to investigate the influence of seasonal freezing-thawing soils on seismic performance of high-rise cap pile foundation in permafrost region, quasi-static tests were carried out on two 1/8 scaled models. The hysteretic behaviors and damage characteristics of the pier-pile-soil ...
and a shifting of the resonance frequencies of the intact concrete specimen was commonly observed. The degree of the amplitude-dependent resonance frequency shift can be evaluated with a hysteretic nonlinearity parameter. The constitutive equation of a nonlinear elastic solid [33,34] is as follows: ...
