Static And Dynamic Analysis Of Staggered Floor Structures

Research of staggered floor structures has become a hot problem in the field of engineering long with extensive application on staggered floor structures in building structures. Column shearing force computation of the staggered floor structures is the key problem. The mechanical analysis of staggered floor structures is more complex than the transmission mechanism of the normal frame structures, because it is related to many factors. At present, its research is less and structural seismic research of staggered floor structures is much less. With the quick boom of economy, the formalism of staggered floor structures is increasingly complicated and the research of staggered floor structures is essential. Building structures for staggered floor aliti are chosen for this study. Main research work is as follows:(1) The recent research and development trend staggered floor structures are reduced;(2) The column computational formula of the containing staggered floor structures and the mixed staggered floor structures under the horizontal loads are deduced by using the D value law. The deducing formula is little error and simple, and accord with fact. The formula is applied to scheme design;(3) The column shearing force formula are deduced when column section coefficientηis changed, a case study is carried out to discuss the influence of the middle column shearing force on the change ofη;(4) The effect of shearing force,bending moment and displacement of the middle column for staggered floor altitude under statical loads are researched;(5) On the basis of structures dynamic analysis theory, the self oscillation characteristic change law and staggered floor column shearing force, the displacement law of staggered floor structures under dynamical effect are researched;(6) The present popular control methods of the site of staggered floor in building structures are introduced.
