Seismic Performance Of High-rise Structure Based On New Latticed Concrete Wall

Expandable Polystyrene latticed concrete new wall structure belongs to the light,for an earthquake-prone highly centralized state,and the urban population and wealth,in view of the advantages of lightweight,short time limit,especially is suitable for post-disaster reconstruction.At present domestic and foreign research on lattice type concrete wall structure is a multi-storey apartment and more homes,the current domestic specifications for cement polystyrene membrane shell lattice type concrete wall building height,the interlayer displacement Angle limit has yet to make that clear,so that make the building structure security there is a huge hidden trouble.Therefore,in this paper,the top cement polystyrene membrane shell lattice systemic research on the seismic performance of concrete wall structure,so as to seismic design of high-rise lattice wall structure provide beneficial guidance.This article is based on structural dynamics and seismic building structure,adopt the method of combining the theoretical analysis and numerical simulation,around the top 8 degree earthquake under the action of cement polystyrene membrane shell lattice seismic dynamic response of the concrete wall structure and seismic performance change law to carry out the research work.This paper conducted the following research work and obtained some valuable research results:(1)Through the establishment of the grid size is 400 mm * 400 mm lattice column size is 160 mm cement polystyrene lattice shell mould high-rise structure elastic-plastic mechanics analysis model of concrete wall structure is studied in EL Centro wave,TAFT wave and artificial waves under the action of difference in stress distribution and displacement variation,12 layer lattice shell mould cement polystyrene concrete wall structure in more than 8 degrees in seismic response under the action of earthquake resistance,the basic dynamic characteristics.(2)The key and lattice column size 140 mm,180mm and 200 mm respectively of high-rise lattice type cement polystyrene membrane shell concrete wall structure are compared,and found the different core column diameter change law of seismic dynamic response of the high-rise building,it is concluded that the lattice column size is 140 mm,the structure of the carrying capacity of basic meet 8 degrees fortification demands and maximum plastic interlayer displacement Angle;Lattice column size for 200 mm basic conform to the stipulations of the torsion effect limit.(3)High-rise frame structure is studied the peripheral lattice wall using cement polystyrene membrane shell concrete walls,shear wall and the hollow block,a detailed analysis of the top cement polystyrene membrane shell lattice seismic dynamic response of the concrete wall structure change rule,points out the guarantee structure shall not exceed the maximum plastic interlayer displacement Angle limits under the premise of that new lattice type concrete wall structure deformation and energy dissipation capability.For high-level cement polystyrene membrane shell lattice type concrete wall structure seismic design provides a valuable reference.
