Studies On Anti-earthquake Capacity Of Bent Struction Under The Interaction Of Ground-structure

The essay combines "Code for Seismic Design of Buildings "(GB50011-2001), analyzing and discussing bent structure of one-story industry buildings tinder the interaction of the seismic, ground-structure, and works out calculation model for bent structure's dynamic period about the depth of burying foundation and toft transmutation; the model is employed expediently, adapts to actual engineer construction design at present.According to theory of bent structure, the paper applies the moment balance and potential energy theory, and works out the modified modulus 1 and 2 for the depth of burying foundation and toft transmutation ,which effect buildings dynamic period. The result indicates: modify dynamic period relates to the sort of ground , toft structure. 1>1, 2 >1 indicates the common burying depth , 2<1 indicates burying depth is deep. Analysis indicates if without thinking of the interaction of ground- structure, anti-earthquake designing of bent structure and reliability evaluation go conservative, so that anti-earthquake designing of bent structure would take the interaction of ground-structure into consideration.Based on the general design of bent structure .aiming at multi-complexion bent structure ,the essay calculates the dynamic period and domino effect of earthquake ,66 groups in all about shearing force(Q)and crooked (M) of control section .the essay chooses appropriate regress parameter through repeating attempt ,and makes use of Origin regress analysis program protract dot chart of multi-structure ,through multinomial regress analyse , finally works out the simplified formulas for single-stride bent with different stride shearing force(Q) and crooked road (M) of control section . The validation indicates the simplified formulas in the paper are proper.Considering the interaction of the ground-structure, the paper works out the simplified formulas for anti-earthquake designing of bent structure, provides a sort of designing approach to calculating in reasonable and handy method. There is referenced and applied worthiness to actual engineer .But its applied scope is still limited, and the further study is needed.
