Abstract:
<strong>Abstract</strong><strong>:</strong> In this research work, the vibration reaction of a massless or massive raft foundation is investigated. The raft foundation is located on a homogeneous linear-elastic half space and faced to external dynamic loads. The elastic half space, signifying the medium of soil, is formulated by a semi analytical method in a complex response. Hence, this work is analyzed in time-domain by employing inversion fast Fourier transformation for impedance coefficients of subgrade soil. The foundation mat has to be discretized into a number of finite elements, which

Abstract:
Simplified methods of static free head stiffness of the semi-rigid foundation under lateral loads were limited to flexible or rigid behavior by the critical length of piles. This would lead to errors when predicting the static or dynamic performance of their upper structures in OWT Systems. This paper presents a comprehensive analysis of the head static stiffness of the semi-rigid pile without considering the critical length. Firstly, case studies using the energy-based variational method encompassing nearly twenty thousand cases were conducted. These cases involved different types of foundati

Abstract:
To obtain the pressure distribution model on the sole plate of semi-rigid light steel column footing, the deflection formulas of beams with free ends on elastic foundation subjected to arbitrarily concentrated load and arbitrarily trapezoidal load were developed by applying the Winkler model of elastic foundation beam and initiate-parameter expressions of deformation and internal force by presetting boundary condition and calculating with Maple software.

Abstract:
Ultra-soft soil is distributed in coastal areas around the world and has poor engineering properties. There is a significant difference in settlement between semi-rigid pile and surrounding soil under embankment load. Based on existing research results, the settlement calculation formula of ultra-soft soil composite foundation reinforced by semi-rigid pile is derived in this paper. Based on the Alamgir displacement model, assuming a three-zone model of pile skin friction with a negative skin friction plastic zone in the upper part of the pile, an elastic zone in the middle part of the pile, an

Abstract:
Significant differences between the predicted and measured dynamic response of 3D rigid foundations on multi-layered soils in the time domain were identified due to the existence of uncertainties, which makes the issue a complicated one. In this study, a numerical method was developed to determine the dynamic responses of 3D rigid surfaces and embedded foundations of arbitrary shapes that are bonded to a multi-layered soil in the time domain. First, the dynamic stiffness matrices of the rigid foundations in the frequency domain are calculated via integral domain transformation. Secondly, a dyn

The bearing capacity of residue pile composite foundation formed by deep dynamic compaction, shorted for DDC, is calculated and analyzed by ANSYS finite element software. The analysis results show that pile body and soil between piles have a good coordination, residue pile composite foundation is semi-flexible and semi-rigid and the effect of consolidating foundation is obvious. The purpose of foundation treatment should be taken into consideration primarily to provide reference for future similar projects.

An optimization technique for designing the steel space frame with T-stub semi-rigid connections and interaction between soil and structure is presented in this article. A three-parameter-based elastic foundation model is utilized to investigate soil-structure interactions (SSI). To enable two-way data transfer for all optimization methods, computer software was developed using C# version 17.8.6, which connects to SAP2000-OAPI version 22. Particle swarm optimization (PSO) and teaching-learning-based optimization (TLBO) are employed for optimal designs. These optimization techniques choose prof

Abstract:
Most often, in the case of typefied prefabricated systems, foundations are designed and constructed as prefabricated elements as well. When the structure is exposed to high intensity loading and founded on a weak soil, beam foundations are often used instead of pad foundations. Beam foundations, stiffening girders, as well as beams which support the fa?ade elements or partition walls, are treated as beams on elastic foundations, while joint of these girders to pad foundations or vertical support elements of a precast structure can be treated as semi-rigid.

Abstract:
This study is an attempt to analyze the load &amp;ndash; settlement behavior of short composite caisson foundation using the continuum approach. The steining considered to be rigid, undergoes rigid body translation and hence is treated as an incompressible cylinder while the core inside is analyzed as a compressible pile. Only compatibility of vertical displacements is considered in this analysis. The soil displacements are calculated at mid points of the outer surfaces of each element, and at the centers of bases of steining and granular core by integrating numerically the Mindlin's solution for a vertical point load inside a semi-infinite medium. A detailed parametric study is carried out to evaluate the relative influence of each parameter on the overall deformation response of the composite foundation. The results encourage the use of the above foundation for alluvial lowlands.

The Wave Finite Element Method (WFEM) is implemented to accurately capture travelling waves propagating at a finite speed within a bouncing rod system and induced by unilateral contact collisions with a rigid foundation; friction is not accounted for. As opposed to the traditional Finite Element Method (FEM) within a time-stepping framework, potential discontinuous deformation, stress and velocity wave fronts are accurately described, which is critical for the problem of interest. A one-dimensional benchmark with an analytical solution is investigated. The WFEM is compared to two time-stepping
