Elastic-Plastic Analysis On The Static Property Of Short Limbed Wall Structure

Short-limbed wall (SLW) is an intergradation of structure style between erose-section-column frame and conventional shear wall structure. This kind of Structure can gain better economical benefit and excellent structural function. It is good to energy saving as well. Short-limbed wall (SLW) has become one of the most important structure forms for residence projects with10-25 stories.According to the finite element theory and the computer simulative principle basic mentality, using finite element analysis software ANSYS, the load capacity, deformation capacity and ductility of short- limbed wall are tested by push-over simulative test, and carried on the optimized analysis to its influential factors.Firstly,3D unit SOLID65 is used in ANSYS to establish the finite element analysis model of short- limbed wall. Then changing some influential factors such as concrete strength rank,couple beams span to depth ratio,ratio of axial compressive force and sectional depth-thickness ratio, the simulative test is carried on the short-limbed wall. Though grouping comparison method the paper analyzes the influence of each factor to the load capacity, deformation capacity and ductility, as well as have the reasons why it leads to the influence, then carries on the optimized analysis, discovers the optimized value of each influential factor, and does the analysis to the broken process of short- limbed wall.Secondly, this paper, seismic analysis of elastic-plastic seismic response is done on single-layer short- limbed wall and the upper short- limbed wall. In seismic analysis, The element is analyzed with different parameters, such as the coupling beams span-height ratio, limb thickness ratio and so on. The influences of these parameters are studied.Through the static analysis and seismic response under the action of elastic-plastic analysis, this paper provides some suggestions and the basis for the design of short-limbed wall.
