Analysis On The New Low-Cost Isolation Technical For Rural Housing

The vast rural area is relatively weak seismic fortification areas. The housings of townsand villages are the relatively weak seismic fortification and almost have no seismic measures.Once the earthquake happens, most of the houses in towns and villages are damaged severely,many people died. Isolation technology provides an effective way to improve the seismicperformance of building. The traditional steel-reinforced bearings have been used in practicalengineering. It has been confirmed that isolation technique can avoid the earthquake damageduring past earthquake experiences and has amazing effect. However, traditionalsteel-reinforced bearings are large, expensive, and heavy, it is difficult to use to houses in thevillages and towns wildly.In this paper, the new low-cost isolation technologies for 1-story to 3-story masonrystructure in rural area are researched. The new low-cost isolation device -- fiber-reinforcedbearings use fiber layers instead of the steel plates, and abolish of the upper and lowerconnection plates, so the cost and weight of the bearings reduced significantly. What is more,this isolation bearings'isolation effect is obviously, their production process is simple, andwith automatic reset function. It can apply to the housing in high seismic intensity andunderdeveloped areas, to improve the seismic performance of village housing.Protecting thesafety of the lives and property of the villager under the threat of the earthquake.Based on the research of theory, experimental and finite element simulation analysis ofthe new bearings, the mainly researchs are carried out in the following: 1) Researching thetypical domestic rural area to understand the typical housing construction in rural areas,village structure, seismic performance and the status of seismic fortification of the rura houseswere presented.And provide a reliable basis for the study of the new low-cost fiber-reinforcedbearings. 2) The study of the theoretical of the fiber-reinforced bearings is described. Thesystems of theoreticals are established. 3) The nonlinear analysis of the dynamiccharacteristics of fiber-reinforced bearings by finite element software ANSYS is presented. 4)The test of low-cost fiber-reinforced bearings is presented. Such as the test for theircompression characteristics, the test for their shear properties, the test for their compressionand shear properties of relevance and the test for their ultimate mechanical properties .Giventhe range of the stiffness and damping and other mechanical characteristics of thefiber-reinforced bearings. 5) Based on the two story masonry structure housing whichcommonly used in rural areas, the calculation analysis of the isolated village houses which usefiber-reinforced bearings were presented. 6) An model (ratio of 1 / 2) of villages masonry structure housing installed by fiber-reinforced isolator are designed and manufactured in thispaper, simulating earthquake shaking table test and comparing analysis with the samenon-isolated masonry building model, And using finite element software SAP2000 for modalanalysis and time-history analysis, Studying of the seismic capacity of the two kinds ofisolated and non-isolated structural system under earthquake. 7) A series of theoreticalresearch of the parallel composite isolation system which use of the fiber-reinforced bearingsand friction bearings are described.Finally, some conclusions are given and the topics for futher research are presented.
