The modeling of deadweight using Finite Element Method(FEM) software in structure analysis is accounted for,and equivalence graph,the maximum or minimum value of stress and displacement under the condition of plate s deadweight are achieved.

The research is mainly focus ed on using law of energy through formula deduction to separately rough estimate the relation of cable force and frequency(or fundamental frequency) with reckon ing in the influence of cable’s deadweight under three circumstances of hinge j oints in two sides; hinge joint in one side, fixed joint.

Placing driving motors in the dexterous robotic fingers will enable the fingers self weight to have a greater influence on its operation capability.

This paper describes the weighing method and results of self weight of 70-m span box girders of Hangzhou Bay Sea-Crossing Bridge and proposes a way that can precisely measure the self weight of the 70-m span box girders,making use of the equipment at the construction site.

The paper introduced the cause and feature of collapsible loess with self weight for Yanghou Expressway,and proposed relative treatment measures for reference.

Research of Estimating the self-weight of Miter Gates in Locks of Large and Middle Hydraulic Projects;

The 3D digital simulation of the stresses of Xiaowan arch dam under different self-weight exaction ways and initial impoundment process has been done.

This article gathers a large amounts of data of the weights of miter gates in locks of large and middlc hydtaulic prjects, and by using the two-dimensional regression analysis, gives a couple of experience formula to estimate the self-weight of opter gates in locks.

The formula method of virtual work which was extensively applied in the structure optimization design is the rational formula method,but the dead weight and the inertia load of the structure were neglected in the past solution of the equation of virtual work,which resulted in the inaccuracy of the formula and result.

Influence on Wrapping Angle by the Gravity of Belt;

The gravity of rock masses and denudation are important factors in the construction of initial stress field.

The structural features of K 18 series coal hopper cars and such problems as insufficient strength, over weight of tare are described, the causes to over weight of tare are mainly analyzed, and the new structural design thought is put forward.
