Abstract: An approach to finding the optimal layout of prefabricated vertical drains (PVDs) in soft soil treatment, which has the minimum amount of PVDs and meets the requirements for the degree of consolidation, is proposed. Because ...

Abstract: The paper presents the optimization of toroidal shell crosssections under internal pressure. The wall thickness distribution along a circular centerline is derived in an analytical form. In membrane solution, this crosssection ...

Abstract: This article presents an approach to the minimum weight design for toroidal shells with strengthening component subject to internal pressure. The optimal shape is obtained by adjusting the geometry and wall thickness of ...

Abstract: This paper considers the determination of plastic instability pressure in toroidal shells under internal uniform pressure. Analytical and numerical approaches, as well as verification by experiments, ...

Abstract: The design of mechanisms for the static balancing of a rotating and weight-varying link has tremendous implications for mechanical structures and robotic systems. This article presents a compact gear-spring mechanism (CGSM) ...

Abstract: This paper presents a method for realizing a gearspring balancer (GSB) that can cope with variable payloads and its application to serial robots. The GSB is constructed with a threegear train articulating a nonzerofreelength ...

Abstract: This paper presents a gravity-balancing method for a two-degree-of-freedom (2-DoF) parallel robotic platform with variable payloads. The robotic platform is constructed with a parallelogram-based five-bar parallel mechanism, ...

Abstract: This paper presents a method for realizing a gear-spring balancer (GSB) that can cope with variable payloads and its application to serial robots. The GSB is constructed with a three-gear train articulating a nonzero-free-length ...

Abstract: Abstract. Body weight support systems (BWSSs) are widely used in rehabilitation to assist patients by completely or partially unloading body weight, thereby reducing joint loading and enhancing stability during gait training. ...

Abstract: A new service limit state (SLS) design procedure for drilled shafts is described, which utilizes strength resistance factors calibrated to achieve a target probability of failure. The new procedure can be used for varying ...
