High Level Structure Transformation Level Situationstress Analysis In Vertical Stress

When lower part the high-rise construction the floor verticalstructure system or the form and upside the floor difference isbigger, must in the structural change floor establishment transformation level structure.The present paper mainly uses ANSYS to transform the structure(including to transform Liang, empty stomach truss, adds strut emptystomach truss three kind of transformations levels structure) carrieson the finite element analysis under the vertical load function stressand the distortion. Has emphatically analyzed two kind of situationsto the superstructure: Shearing force wall structure and portal frameconstruction. Combines above several kind of situations, altogethersome six kind of structures finite element analysis.In the analysis process, is uses thesuperstructure to use 3-4, the substructure uses 1 simplificationmodel to carry on the analysis and the discussion, like this obtainsthe result with uses the result error which the complete floor affectstogether in 5%. Regardless of is regarding the deck shearing forcewall or the portal frame construction, the transformation trussbecause has established two transformations summer beams, avoided abigger pulling force concentrating on a Liang, therefore the endogenicforce generally transformed Liang Xiaohen to be more than, wasadvantageous to enhances the structure the earthquake resistanceperformance. If again joins two diagonal struts, positive and negative can obtain redistributes, compared with the average, thediagonal strut has undertaken part of crosswise stress, regardingmatches in the muscle the transverse steel request to reduce.After transforms Liang and the transformation truss contrast analysis,has obtained the transformation truss superiority from the concretedata, although at present transforms the truss also to have the verymany constructions aspect the difficulty, the stress has nottransformed Liang to be clear, but took one kind of new transformationstructural style, will plant in the later high level structuretransformation level design, certainly will be able to take animportant alternative scheme. At the same time, this kind of finiteelement analysis also is the supplement analysis which must carry onin the actual engineering design.
