Study on cooperation mechanism of hybrid masonry structure with RC framing under the action of vertical force

Firstly,the computational formula of axial force distribution coefficient for the framework and wall on hybrid masonry structure with RC frame is derived under the action of the vertical force.Theoretical analysis to determine the affecting factors of cooperative work on structures under vertical forces and finite element model is established to study the impact of beam height,column height,wall height etc.on axial force distribution of frame and wall.Results obtained indicate that impact of column section height on axial force distribution of frame and wall is the largest and the variation is around 10%.Impact of masonry elastic modulus on axial force distribution of frame and wall takes the second place.Impact of beam height and wall height on axial force distribution of frame and wall is not obvious.The accuracy of computational formula is verified by the comparison of results from the model analysis and formula calculation respectively.
