Influence Of Slab On Frame Beam Of RC Frame Structure

In the design of building structures,RC frame structure is a type of structure which is widely applied.Because the RC frame structure is the overall cast-in-place, structure member form a whole.Therefore, the mutually connected structure elements are in interaction and compatible deformation. So is the slab and frame beam, slab and frame beams as structural components in the horizontal direction, In addition to the two integral cast-in-situ and connection, under the vertical load or action, they must be in coordinate deformation and interaction.However, in the analysis of building structure design,because the cast-in-situ slab and frame beam interaction research is not very mature,so the code for design of building structure in the world are in effect on frame beam of cast-in-place board gives only approximate numerical or general fuzzy concept.A large number of experiments and theoretical analysis have proved,cast-in-place plate have different effects on deformation ability,stiffness and bearing capacity of the frame beam.But the designers of building structure is not clear on the magnitude of the effects,this directly leads to the analysis of frame structure design buildings when in face of high load or action (such as large earthquake), frame structure could not be expected to form the failure.Until now, many domestic and foreign scholars and the structure designer about the influence on the frame beam of RC frame structure of cast-in-place board according to different research direction do the various experimental and theoretical analysis.On the basis of the existing achievements,according to the seismic design of "strong column and weak beam", this paper about affect the cast-in-place board on frame beam is determined in the following aspects:1) Various experimental results and the theoretical analysis results on frame structure on the basis of existed are summarized, and organize personal understanding of the impact of the cast-in-place board on frame beam and arrange thinking.2) Establish the board framework model and no board frame model, then loading and pick up data extraction model,at last do comparative analysis on the structure of data to different models,summarize effect cast-in-situ slab of frame beam and the reasons and the effective width value of the slab is proposed.At the same time, summarize and analyse effect of cast-in-place slab on the overall structure.3) Based on the engineering requirement, improvement suggestions are given in the actual structure design of plate effects of specific.
