tables of maximum bending moment, shear force and support rections for simple bridges with span lengths ranging from 2m to 250m are presented.loadings are selected according to the specification given by the highways and transportation ministry of iran. the procedure of using the tables is shown by means of an example.

To date, transverse and vertical forces applied eccentrically to the axis of dental implants in the molar area during oral function have not been quantified. A specially designed load cell placed directly in the implant allowed for measurements of bending moments. Results of both load directions were compared to each other and to the loads applied vertically along the implant axis. The stress i...

Previous studies of twisting have revealed substantial cocontraction of agonist and antagonist muscles within the torso when torsional moments are generated. The objective of the current study was to quantify the activations and cocontraction of eight trunk muscles as subjects maintained an axially rotated trunk posture and resisted external applied bending moments. Ten subjects twisted their t...

This paper investigates the behaviour of exposed column base-plates with four outer anchor bolts subjected to monotonic loading. The results six full-scale tests on steel base-plate connections uni/biaxial bending moment are presented. influence thickness and axis orientation connection response is thoroughly investigated. In addition standard measurements, Digital Image Correlation has been us...

The evaluation of liquefaction effect on the dynamic moment of stabilizing piles is potentially significant. Based on the dynamic centrifuge modeling of a slope reinforced with a row of copper model pile, this paper not only analyzed the response of dynamic pore pressure, earthquake deformation and macroscopic phenomenon measured in the response of the reinforced slope, but also simulated the r...

A parametric study on circular thin-walled pipes subjected to pure bending is performed. Both straight and curved pipes are considered. Ratio D/t, initial pipe curvature and internal pressure are the parameters varying in the analyses. The study is mainly FEA-based. It is found that negative curvatures (opposite to bending moment) considerably increase stiffness and buckling limit of the pipe w...

To understand the mechanical behavior of fast-starting fish, we modeled the pumpkinseed sunfish, Lepomis gibbosus, as a longitudinally-loaded beam that behaves as an elastic column eccentrically-loaded by lateral musculature. Since bending moments are a function of the shape of the body, we used real sunfish to determine, (1) from cross-sections, the effective moment arm of the lateral musculat...

BACKGROUND Short-segment pedicle screw instrumentation (SSPI) is used for unstable burst fractures to correct deformity and stabilize the spine for fusion. However, pedicle screw loosening, pullout, or breakage often occurs due to the large moment applied during spine motion, leading to poor outcomes. The purpose of this study was to test the ability of a newly designed device, the Trans-Endpla...
