It is a new method to find the displacement function form in analysis of shear lag effect on thin - walled box girder
12.
The analysis of shear lag has an important significance on safety and economy to the design of modern bridges
13.
However , there is shear lag effect in thin - walled box girder when thin - walled box girder is bent in the longitudinal direction
14.
To give more information about the shear lag phenomena in the short leg walls , a computer program of finite element analysis is compiled
15.
In the thesis , fem and plexiglass model test are used for the research of shear lag effect on double - level continuous box girder
16.
In the design of steel box - girder bridge , the shear lag effect of box - girder with wide flange and small span is outstanding
17.
This thesis studies shear lag effect on three representative forms of cable - stayed bridge cross sections by different theoretical methods
18.
Under tensionloading , these gusset plate connections can be susceptible to shear lag failure of thehss since only a part of the tube cross - section is connected to the plate
19.
Furthermore , combining with the experiment of yibin zhongba jinshajiang cable - stayed bridge concrete model , this thesis using finite element method studies shear lag effect of the cable - stayed bridge with n cross section and offers suggestion to the project
20.
Then it was necessary to study the matrix crack and delamination damages in detail , which occurred with the maximum probability and played the most important role on fwc failure . two models about damage analysis were established b y using energy method and shear lag method . the mechanism of damage and the effect to structure performance caused by damage are studied further
