The Influence Of Anti-Seismic Of Retainig Board On Multilayer Lightweight Steel Residential

The exterior wall retaining materials of lightweight steel structure residentialmainly use foam-like material aerated cement, lightweight concrete hollow materials,lightweight steel keel composite wall material, etc. These materials participate in theforce of actual structure because of its good performance. The role of these retainingmaterials are ignored in the structure design. This article starts with Naj AutoclavedLightweight Concrete(NALC board) of exterior wall of retaining material of asix-layer lightweight steel structure residential and analyzes the plank to the influenceof the structure seismic behavior using finite element analysis. This research workmainly include the following parts:(1)The paper, using response spectrum analysis and time history analysis of thetwo methods, analyzes the bottom shear, storey displacement, inter-storeydisplacement angle and the stress value of NALC board when the original structureare analyzed with or without NALC board on the condition of6,7,8frequent seismicforce. We can obviously see through the comparison of the two kinds of structure,considering the role of NALC board can effectively improve the rigidity, and thestorey displacement and inter-storey displacement angle can be effectively controlled.(2)The paper, using the finite element analysis method, analyzes the change ofthe plastic hinge and the stress value of NALC board when the original structure areanalyzed with or without NALC board on the condition of8infrequent seismic force.Through the analysis, we can see that considering the role of NALC board caneffectively reduce the plastic hinge and keep more components in the elastic state.(3)Refering to the related standard, the paper checks for the date of storeydisplacement and inter-storey displacement angle on seismic force. Through thechecking date provides reference for the design of the similar structure.
