Floor Partial Open Hole On The Impact Analysis Of The High-rise Building Seismic Action

High-rise buildings all over the world, our country’s medium cities also abound.Thestructure of high-rise building has a growing in order to guarantee the safety, the functionality,the economy and other factors of high-rise building structure. Due to the needs of the buildinguse function, floor open hole is inevitable. Through the theoretical analysis shows that flooropen hole will more or less about the quality of the structure, stiffness, stress state of forcetransmission path and etc. So, for how to open the floor openings need to be studied.Established a frame structure and a shear wall structure of the high-rise building asexamples. And on the five analysis model is established, respectively. For the mouth of thecave floor open hole ratio and different model horizontal position. Level in the mouth of thecave floor open hole central angle, and symmetry.Use the PKPM software Satwe program foranalysis and calculation model, The analysis of the indicators have the dynamiccharacteristics(variation period,vibration mode,period ratio),the deformationcharacteristics(interlayer displacement angle, displacement ratio),the internal forcecharacteristics(shear,bending moment).Through the analysis of the difference of each index,summed up the local open hole in the floor and reasonable way and advise local open hole forhigh-rise building structure floor slab.
