Tensegrity frameworks are defined on a set of points in Rd and consist of bars, cables, and struts, which provide upper and/or lower bounds for the distance between their endpoints. The graph of the framework, in which edges are labeled as bars, cables, and struts, is called a tensegrity graph. It is said to be strongly rigid in Rd if every generic realization in Rd as a tensegrity framework is...

The definition of rigid floating piles in engineering applications remains ambiguous. This paper develops a numerical model piled embankments and the modeling method is verified through cases. Utilizing this model, critical bearing capacity foundation for firstly determined to be approximately 150 kPa. Subsequent parametric studies show that soil arching embankment begins occur when ratio heigh...

A direction-length framework is a pair (G, p), where G = (V ;D,L) is a ‘mixed’ graph whose edges are labeled as ‘direction’ or ‘length’ edges, and p is a map from V to R for some d. The label of an edge uv represents a direction or length constraint between p(u) and p(v). Let G be obtained from G by adding, for each length edge e of G, a direction edge with the same end vertices as e. We show t...

Motivated by the observed (successful and unsuccessful) performance of numerous structures on top of, or immediately next to a normal fault that ruptured during the Kocaeli 1999 earthquake, this paper: (i) develops a two-step finite element methodology to study the propagation of a fault rupture through soil and its interplay with the foundation–structure system, denoted hereafter “Fault Ruptur...

Through conducting a comparative experimental study of small-aspect-ratio isolated structure models on multi-layered soft soil foundations and rigid foundations, this paper investigates the influence soil–structure interaction (SSI) effects seismic response structures foundations. An energy balance equation for systems considering SSI is proposed, impact dissipation analyzed in depth. The analy...

The traditional anchoring mechanism of the traction robot is rigid, which easy to be stuck in wellbore. In order solve problem produced by rigid robot, a novel was proposed based on spring type inclined block. key make motion whether can anchored wellbore under action force. Therefore, rigid-hyperelastic coupling dynamic model force established. On basis, effects span, width, thickness and cham...
