Abstract: In this paper, a modular modeling approach of multibody systems adapted to interactive simulation is presented. This work is based on the study of the stability of two differential algebraic ...

Abstract: The type of joint used is important with respect to the behavior of grid shells. Prototype static experiments and numerical analyses were conducted to study the mechanical behaviors of a new type of joint: bolted joints ...

Abstract: The stationary response of multidegree-of-freedom (MDOF) strongly nonlinear system to fractional Gaussian noise (FGN) with Hurst index 1/2 < H < 1 is studied. First, the system is modeled as FGN-excited and -dissipated ...

Abstract: Variable compressibility must be considered in settlement calculation of soft soil stratums, especially for thick soil layers. This study proposes a new simplified method to calculate the settlement of a thick soil layer ...

Abstract: Considering the characteristics of the surrounding rock temperature and water replenishing direction of tunnels in cold areas, to study the frost heave deformation law of surrounding rock under a certain stress environment, ...

Abstract: Many wake oscillator (or lift oscillator) models are limited to studying the vortex-induced vibration (VIV) of linear structures excited by a constant-speed fluid flow. However, in wind engineering, real wind is typically ...

Abstract: In this study, a novel effective stress cell based on fiber Bragg grating (FBG) sensing technology is developed for direct measurement of effective stress in saturated soil. The primary concept of direct measurement is ...

Abstract: It is very important to accurately calculate the frost heave force for the frost resistance design of tunnels in cold regions. A computational model will divide the lining and surrounding rock into eight parts, such as the ...

Abstract: Estimating the permanent strain of granular materials in embankments subjected to cyclic loading is a major challenge for transport engineering projects. In practice, the development of permanent strain can be divided into ...

Abstract: Stone columns (SCs) and sand compaction piles (SCPs) are widely utilized as effective methods to increase the bearing capacity and reduce the settlement of soft ground. In this study, a physical model test was conducted ...
