Overpass calculate examples and (analysis,)the distinguishing condition is introduced that additional bending moment is neglected to calculate the (maximum) normal stress of combined deformation practically.

The article discusses the pile foundation stability of piled wharf and determination of calculated length and additional bending moment of piles.

Through analysis on cracks in the slabs of a factory building, this paper regards it necessary to consider the effect of additional bending moment caused by beam deflection in slab smictural design of me lorg - span steel rein fored concrete fram structure factory building.

The effects of friction moment and additional moment on the stability of rolls for the first time was considered and the optimum offset model for the four high mills was set up.

Meanwhile,the deduction of unified equations of various beam-columns additional moments and the discussion of the effects that factors of sorts exert on additional moments are also performed.

This paper covers the set up of the space coordinate axis of the ring fork U joint, and through the analysis of the additional moment in the ring fork U joint it presents how the value of the additional moment is obtained.

Based on theory analysis of the rolling coupling and roller coupling, it is known when rolling coupling axis direction displacement, radial displacement and angle error are compensated, the rollers are rolling on the rolling path and the abrasion of rolling is slight, the friction force and the add-moment and power consume are small which will not influence the equipment performance.
