TL;DR: In this article, an idealized 2-dimensional plain strain finite element seismic soil-structure interaction (SSI) analysis based on a substructure method was performed by using original software developed by the authors.
Abstract: This paper presents an idealized 2-dimensional plain strain finite element seismic soil-structure interaction (SSI) analysis based on a substructure method by using original software developed by the authors. To investigate the effects of SSI the following types of analysis were performed: linear SSI analysis and non-linear SSI analysis. For the same structure, analysis was carried out by the procedure without the consideration of soil-structure interaction. These computations were achieved for different peak accelerations: 0.15g, 0.30g and 0.45g. In another case for a different site soil with a shear wave velocity of 200, 300 and 500 m/s, a linear SSI analysis was performed. In the analysis, the radiation condition was fully accounted for, the soil plasticity was modeled with the Von Mises failure criterion, basemat uplift was not considered, and the action of gravity was not taken into consideration.

TL;DR: In this article, a new physical model was developed in Amirkabir University of Technology, which is capable of simulating and monitoring flexible pipes under different conditions, including the depth and position of the buried pipes as well as the type and density of the surrounding soil.
Abstract: The safety of lifelines, as the most important urban facilities, under different conditions highly depends on the safe design and performance of these buried structures. This cannot be achieved unless their actual behaviors are well realized and considered at the designing stage. To study the behavior of buried pipes under different loading conditions, a new physical model was developed in Amirkabir University of Technology. The model is capable of simulating and monitoring flexible pipes under different conditions. The depth and the position of the buried pipes as well as the type and density of the surrounding soil can be changed and controlled. The cyclic loads with different amplitudes, and cycles as well as the monotonic loads can be generated and applied on the soil surface. The generated load can be applied on the pipe centrally or eccentrically. The radial deformations of the tested pipes as well as the shear and normal stresses on the boundaries of the soil trench were measured by a special probe and data acquisition system developed for this model. A series of different tests were carried out to study the soil-pipe interaction. The main factors affecting the behavior of these buried structures were studied and described in the paper. Among them the soil density and the pipe depth proved to be the most important factors affect the soil-pipe interaction. The influence of the impact at the first cycle was also found one of the main factors affecting the pipe behavior. There are also many other results the descriptions and discussion about which are given in the next sections.

TL;DR: In this paper, a discrete-continuous model to analyze a buried structure response to static surface loading as well as the soil gravitational load at "service-state" conditions is presented, which can represent positive and negative arching and provides an understanding of the effects that various variables have on the arching type and on the structure response.

TL;DR: In this article, an analytical model is developed to estimate the buckling behavior of tapered friction piles fully embedded in inhomogeneous soil, and the governing differential equation of the problem is derived with associated boundary conditions and is solved by using the Runge-Kutta method in combination with the Regula-Falsi method.
