Research On The Performance Of L Form Short-shear Wall

The using of short-shear wall has more than ten years, With the research is continuing,this structure form have become increasingly more mature. As the short-shear walls project isapplied more and more, Technical specification for concrete structures of tall buildingJGJ3-2002is the first time to bring this kind of structure form into the Specification,8yearslater, In2010people modified the specification, enabling people to deepen the furtherunderstanding of short-shear walls. In order to learn more about the L form short-shear wallduring the time of new old takes turn of Technical specification for concrete structures of tallbuilding, first of all, I summarize the difference of short-shear walls between the old and newtechnical specification for concrete structures of tall building. Summarize the differenceelastic-plastic analysis of shear wall of between the applications of different software.Furthermore, I analyze the axial compression ratio limits and the ratio of length-thicknesslimits, at last I analyze the mechanical properties in the different span-height ratio of beams.Secondly, I Introduce the settings of nonlinear/layered shell, the plastic hinge, the constitutiverelation of concrete and reinforced, the realization of nonlinear/layered shell in SAP2000.Continuation I make simple comparison of equivalent frame model and nonlinear/layeredshell model. Finally I use the nonlinear/layered shell element to a single model of double limbL form short-shear walls of static elastic-plastic analysis, the content including axialcompression ratio, the wall limb length, length of wall even the beam wing across the aspectratio. Finally I present the experience of the appropriate reference in design. At last I make thewhole structure analysis with strong limbs and holistic coefficient of different coefficient todo response spectrum analysis, and then introduced the wall limb reinforced configuration,and end with a project example to contrast analysis short-shear walls and ordinary shear wallstructure.
