The stiffness analysis method considering uncertainty parameters of frame hydraulic press with movable eccentricity loading in the early design stage was proposed. The mathematical analytical stiffness of the upper beam with movable eccentricity loading was built. The adaptive Monte Carlo Method was used to calculate the interval of the stiffness with random parameters. The result shows that the stiffness appears higher when the eccentricity increasing. The approach has been tested by measuring the stiffness of a 10000kN frame hydraulic press and a 15000kN frame hydraulic press.

 TThe foundation is part of the structure that directly functions to transmit the load from the weight of the structure above it to the ground. In this study, a rectangular foundation is used which is placed on clay soil with 3 variations in dimensions and 7 variations in eccentricity loading. This data will be used in finding the ultimate bearing capacity value. The purpose of this study was to determine the effect of eccentricity loads on the bearing capacity of rectangular foundations on clay soil types. The method used is the Meyerhof method (1963).

The finite element method is used to investigate the behavior of a strip footing constructed near the edge of a sloping cohesive ground. The effects of variation in footing closeness, loading eccentricity and slope angle are studied also. It is proved that Bowles method overestimates the load carrying capacity of the concentrically loaded strip footings on cohesive soils. Decreasing the distance between the footing and the slope edge, increasing the eccentricity and slope angle reduce the ultimate bearing capacity. Slope effect diminishes as the footing distance from the edge approaches (1.5)

Laser fusion research requires a large number of high-precision large-diameter aspherical components. To improve the grinding efficiency in the component production process, the manual operation time during the grinding process needs to be reduced. The grinding process requires the installation of the dressed grinding wheel onto the grinding machine spindle, and the off-line dressing results in installation errors during the loading and unloading process, which requires more time for manual alignment. To achieve self-aligning, the circumferential contour of the grinding wheel was first restore

Amid the rapid advancement of electronic information technology, the need for cable eccentricity measurement in the industry is increasing both in China and across the globe. Current detection methods have several flaws, including high costs, insufficient accuracy, and instability. In this paper, we introduce a magnetic field-based detection method for cable eccentricity that provides high precision and cost-effectiveness. We position three pairs of magnetic field-collection modules in a circular array to gather magnetic flux density information induced by the electrified cable. We apply the l

The theoretical behavior of beam-columns in braced frames with AISC Type 2 connections is examined here to determine the validity of ignoring eccentricity in the design of columns with flexible connections. The AISC Specification for the Design, Fabrication and Erection of Structural Steel for Buildings is not specific on whether eccentricity should be considered, but the British Standard 449 has specific requirements on the eccentricity to be taken. Neither specification provides any relief for restraint offered by the flexible connection as shown in Fig. 1, nor for the stiffness due to the d

Abstract: The study looks at the effect of eccentricity in load combinations, recognising the importance of non-uniform loading circumstances on structural behaviour. The combination of eccentricity factors and moment distribution not only improves structural analysis accuracy but also makes it easier to identify crucial spots prone to higher stresses. This holistic method strives to optimise structural designs while maintaining safety, efficiency, and adherence to applicable design requirements.Case studies and comparative analyses are used in the study to validate the efficiency of the sugge

The bearing capacity of embedded foundations subject to combined horizontal and moment loading in undrained soils is of interest particularly to the offshore geotechnical engineer. These loadings can be experienced by monopod foundations and offshore manifolds and often take the form of a horizontal load applied at a lever arm height above the foundation base. Previous design methods using the failure envelope approach have suggested that peak moment capacity of a foundation is mobilized with positive horizontal loads, but that peak horizontal load is mobilized with no additional moment loadin

To achieve that, an experimental program that consisted of seven wide beams was conducted.

A cable-stiffened steel column (CSSC) possesses superior stability behaviour compared to ordinary compression columns. In the past, the research emphasis has focused on the behaviours of stiffened columns under axial compression; investigations into their behaviour under eccentric loading is scant. This study aims to examine the buckling behaviour of CSSCs under eccentric loading using experimental and numerical investigations. The effects of pretension in cables and eccentricity on stability behaviours were studied. According to the current investigation, it can be demonstrated that the capac

Analyses showed that an unstiffened beam, supporting a timber or steel post similar to those found in bridge falsework, should be designed for a combination of flange bending and post strength. A series of experiments and finite element analyses were conducted to observe and quantify this limit state and to develop predictive methods for the evaluation of joint capacity.

Results showed that a reduction in load capacity as a result of an increase in eccentricity is more significant for grouted prisms than for their hollow counterparts. At a relatively large eccentricity to thickness ratio, e/t, hollow prisms attained a higher ultimate load than grouted prisms.
