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 understood and considered at the designing stage. A new physical model was developed in Amirkabir University of Technology to study the behavior of buried pipes und...

Non-linear model assess (light) damage. Decoupled soil structural models efficient, fast (probabilistic) analyses. Recent, light earthquakes induced by extraction gas north Netherlands have been linked light, mostly aesthetic damage t...

Abstract. In this study, the seismic soil–structure interaction (SSI) of wind turbine support structures is investigated based on complex mode superposition approach. For accurate and efficient estimation loadings structures, an augmented response spectrum method (RSM) developed, where maximum shear force bending moment non-classically damped system are analytically derived. An empirical formul...

Effects of vibrating structure on the free-field motion are presented through a field experiment at the Euro-Seistest and a corresponding numerical simulation. Ground motion has been recorded by a dense temporary three-component (3C), two-dimensional (2D) seismic network installed at increasing distances from a model building forced into vibration by pull-out tests. The building is a five-story...

A simple prismatic Timoshenko beam model with soil-structure interaction (SSI) is developed to approximate the dynamic linear elastic behavior of buildings. A closed-form solution with complete vibration modes is derived. It is demonstrated that building properties, including mode shapes, can be derived from knowledge of the natural frequencies of the first two translational modes in a particul...

In this study, an efficient method is introduced to predict the stability of soil-structure interaction (SSI) system subject to earthquake loads. In the procedure of the nonlinear dynamic analysis, a number of structures collapse and then lose their stability. The prediction of failure probability is considered as stability criterion. In order to achieve this purpose, a modified adaptive neuro ...

As a result of wind power’s expansion over the globe, offshore turbines (OWTs) are being projected in seismic prone areas. In parallel, industry develops increasingly larger and more powerful generators. Many response analyses conducted so far only consider smaller units. this paper, finite element substructuring model frequency domain is used to compute four reference OWTs from 5 15 MW founded...

The tuned mass damper (TMD) is widely used for vibration mitigation, especially in high-rise buildings where significant soil-structure interaction (SSI) effects are usually involved. This creates a need to consider SSI TMD design. In this work, novel design framework systems with proposed. For response evaluations, structure-TMD modeled as two-degrees-of-freedom (2DOF) system, standing on rigi...
