Abstract


Casting slab of reinforced concrete frame structure is very common in the current structure of the form of a structural system . Floor slab frame structure studies show casting slab bearing capacity , stiffness and deformation properties of the frame structure has a great impact , in particular, the enhanced role of the floor slab flexural capacity of the beam lead to strong beam weak column the occurrence of the earthquake damage have been common , ignored casting slab on the frame structure , frame structure can not always maintained in the earthquake damage in the weak beam overall mechanism failure modes . Will eventually result in a serious risk to life and property losses , and therefore should be fully considered in the seismic design of the framework structure of casting slab on the frame structure . Many domestic and foreign scholars have done a lot of work in the floor slab frame structure are still many issues is not resolved . This paper to do the main work is as follows : In order to more fully consider casting slab frame structure by the model in the literature were summarized and analyzed , drawn should consider how to pour the slab frame structure deformation capacity the impact at home and abroad , and summarizes the research results about the effect of casting slab on the frame structure , and lay the foundation for further study . Using the ABAQUS finite element software with powerful non-linear function of the establishment of a three-dimensional framework model to study the case of different thickness and the casting slab frame structure different Ligament case under different earthquake intensity input dynamic response characteristics , through the layer displacement angle changes to examine the seismic deformation capacity of the floor slab participation framework . Change the model , different reinforcement ratio , the same plate thickness and different thickness , the same reinforcement ratio both cases , the binding layer displacement angle changes as well as floor damage , floor frame structure seismic impact has been described. 4 by comparative analysis of the case of different thickness RBFOR envelope view and a comparative analysis of the different diameters floor slab reinforcement RBFOR diagram to draw the initial value of the effective plate width . In this paper , on the basis of the example model , draw some useful conclusions , make some design recommendations , analysis and design of the floor slab frame structure has certain reference value .
