Research And Analysis Of The Bearing Capacity Of The Floor Without Beam

Floor without beam is one floor structure system which is directly arranged inthe column or wall. There is no beam in this structural system which makes the roomclear height increase. The general requirements of urban planning in many cities inChina subject to certain restrictions on the total height of the building. Floor withoutbeam structure in these cities have larger building space within the limited height ofthe building, which makes maximize economic benefits.Although the floor without beam structural system has many advantages, limitedto a variety of factors affect, until now people has not yet formed a unifiedunderstanding about Work performance, the fundamental mechanism of failure modesand failure characteristics of this structure. It is a task that contemporary structureresearchers need to complete that depth study on the floor without beam calculationsof the structural system theory and design methods.This article by the using of finite element analysis software ANSYS simulationand combining with literature research studied the reinforced concrete floor withoutbeam in the following aspects:（1）To simulate the test pieces in the literature[27], the test results in theliterature as a reference, to verify the accuracy and reliability of the use of finiteelement software ANSYS simulation and in order to master the appropriate modelingand calculation method, so lay the foundation for the full text of the modelinganalysis;（2）To analyze a3×3layout column-free cap floor without beam simulation inthe literature[27], to study the deformation characteristics, internal force distributionpattern, crack development and stress curve;（3）To conclusions summarize previous floor without beam shear, column capfloor without beam floor with the force of the column node at simulation, Todetermine the relationship between the stirrups configuration punching shear bearingcapacity and To make recommendations to the relevant design formulas;（4）To simulate a single block floor without beam which t he verticaldisplacement of the plate edge is limited. Sectional flexural stiffness to change boardfour sides of the beam height realize beam level changes, To explore the impact of thefilm by the board edge level of the beam flexural stiffness effect on the floor withoutbeam carrying capacity. Identify the boundaries of the side support plate with thecolumn of the support plate.
