As for traffic load , two situation were analyzed , symmetrical load and asymmetric load , in each of them , crack top ' s tension stress , shear stress and stress intensity factor were calculated , also the effect of structural parameters were analyzed
2.
Firstly , with uniaxial symmetrical rectangle cross section , the warping displacement function and tangential displacement function under anti - symmetrical load are supposed . then taking shear deformation into account and with potential principle , the governing differential equation for distortion angle subjected to uniformly distributed distortion load is established
3.
For the first time , based on frame structure with large thick raft plinth and many engineering examples , analytic method of interaction that means the analysis on three parts above as a whole with a full consideration of interaction thereof that met the need of the deformation correspond on the boundary was used to research on the interaction of structure and groundsill in this paper . and five models were adopted , which were : ( 1 ) a tube with symmetrical double - axis structure and symmetrical loads , ( 2 ) two tubes with symmetrical double - axis structure and symmetrical loads , and ( 3 ) a tube with symmetrical single - axis structure and symmetrical loads , and ( 4 ) two tubes with symmetrical double - axis structure and unsymmetrical loads , and ( 5 ) two tubes with unsymmetrical structure and loads . based on the middle - thick slab theory from mindli and the model for groundsill from winkle , the deformation character of raft foundation and the distributing rule for resisting force of fundus were studied in details by using b ig - style fem ( finite element member ) software , ansys
