Reflection Of Ground Walls On Mechanical Properties Of Transfer Beam In Partial Frame Shear Wall Structure

Partial frame shear wall structure is one of the most widely used structure systems ofhigh-rise buildings. The most important structural element in partial frame shear wallstructure is transfer girders. Transfer girders converts the horizontal load and vertical loadfrom the lateral force resisting system above the transfer layer to the lateral force resistingsystem below the transfer layer. If transfer girders fail, the whole structural system fails. Ifground shear wall is set under transfer girders, it will have significant changes taken placein transfer beam’s structure internal force, stress, crack, deformation behavior. It has greatpractical significance to study the impact on mechanical performance of transfer girdersaroused by ground shear walls and the extent of the impact.This paper briefly introduced the research and application of partial frame shear wallstructures and transfer girders. The characteristics of finite element analysis on reinforcedconcrete structure are also summarized in the paper. The finite element analysis software,ANSYS, is used to establish local solid model of partial frame shear wall structure withand without the ground walls under transfer beams. This paper studies the impact onmechanical performance of transfer girders aroused by ground shear walls and the extentof the impact under different upper shear wall arrangement and transfer layer location.This paper shows that the ground walls could obviously improve the mechanicalproperties of transfer beams and this improvement varies with different upper shear wallarrangement and transfer layer location.
