Abstract null null To understand the longitudinal structural deformation mechanism of shield tunnel linings, it is crucial to reasonably consider circumferential joints, especially their shearing deformation. Towards that end, first, the dislocation between lining rings caused by the differential settlement of an actual tunnel project in Shanghai was introduced in detail. Next, the longitudinal deformation model of shield tunnels derived from Timoshenko beam theory was revised to predict the act...

Abstract null null Screw piles are efficient anchors to sustain large uplift loads and can be installed with low noise or vibration. Screw piles dimensions are currently increasing, renewing research interest to reduce the installation requirements (torque and crowd or vertical force). The Discrete Element Method (DEM) is an ideal technique to investigate the complex soil behaviour during screw pile installation. Different techniques such as particle upscaling or increase of pile penetration rat...

Abstract null null Multidirectional shearing tests on soils in the laboratory suffer from drawbacks such as non-uniformity of stress and unknown horizontal stress of the specimen. As a promising numerical technique, the discrete element method (DEM) enables investigation of the responses of virtual granular samples under general loading conditions and provides ideal numerical results to overcome the aforementioned limitations. In this study, three different drained cyclic tests, including conven...

Abstract null null This study proposes an efficient full probabilistic design method using an advanced Monte Carlo simulation (MCS) algorithm, so-called generalized Subset Simulation (GSS), for which a concept of design response vector is proposed. The proposed design response vector contains responses of all possible designs and is used to, simultaneously, explore failure domains of different designs. With the design response vector, the proposed approach determines feasible design domains of d...

Abstract null null A mixing-locally polynomial Regression method and Global Sensitivity analysis – (MRGS) procedure is used in assessing foundation and abutment uncertainties of concrete arch dams. Latin hypercube sampling is employed for generating samples in the sensitivity analysis. The model consists of a typical 80 m high arch dam along with its foundation and abutments. A potentially movable rock wedge confined by three discontinuities located in the Karun IV dam’s abutment is incorporated...

Abstract null null Tapered piles have superior benefits over traditional cylindrical piles in resisting axial and lateral loads, being an economical alternative to cylindrical piles. When designing the tapered pile in soft or liquefiable soil, it is necessary to identify its buckling strengths. Notwithstanding, the buckling analysis of tapered piles considering nonlinear pile-soil interactions with geometric imperfections under combined loads has not been well established. This paper presents a ...
