2. The transverse rigidity of bridge surface structure without steel surface plate (simply as “ A'”) is 30.29～45.13 times smaller than that of B, and the longitudinal rigidity of A' is 14.12～22.59 times smaller than that of B;
Constructing a membrance element to treat the combined space non-mo-ment thin shell structures and proposing a transverse element rigidity matrix which balancedfOr its own,the problems caused by transverse rigidity are setted。
The essay summarizes the status of Wuhu Yangtze River Bridge, analyzes the direct causes that lead to speed limit forapproach bridge, which include insufficiency of transverse rigidity for 32 m T beam, insufficiency of transverse rigidity for framed light pier,and poor dynamic performance of freight train.
3. Comparing bridge surface structure without surface plate (A')and bridge surface structure with surface plate (A): The transverse rigidity of A' is only 1.32% ～ 0.44% of that of A , and the longitudunal rigidity of A' is only 3.26% ～ 1.08% of that of A;
Theoretically the varying contact rolling technology can increase the transverse stiffness of loaded roll gap,heighten the control effect of roll bending,improve the distribution of contact force between backup roll and work roll.
Results indicate that the system stability is decided by the vehicle barycenter position and the lateral stiffness of a tire.
However, the lateral stiffness of each of the PDB's load paths is constant.
This is one of the applications of Part (I), in which the angular stiffness, the lateral stiffness and the corresponding stress distributions of C-shaped bellows were calculated.
It introduces lateral stiffness as a practical stability measure to quantify the ability of both circular saw types to resist lateral cutting forces without large deflections.
Design optimization based on a mathematical programming technique involves minimizing the lateral stiffness of the lateral load resistant system for the structure while satisfying specified drift constraints.
The transverse stiffness of the gastrocnemic muscles and the relationship between the strength of the crural muscles and the angle of talocrural articulation were investigated.
In the present work, the influence of the fibre treatment on the transverse stiffness of glass/epoxy unidirectional laminates is discussed.
Axial and transverse stiffness measures of cochlear outer hair cells suggest a common mechanical basis
It has been found that the correction introduced by taking into account the transverse shearing stressesis determined by the ratio of longitudinal stiffness to shear modulus as well as by the ratio of longitudinal to transverse stiffness.
Anisotropic polymer foams have been prepared, which exhibit a Poisson's ratio exceeding 1, and ratios of longitudinal to transverse stiffness exceeding 50.
